FIELD OF EMBODIMENTS [0001] The described embodiments relate generally to search results. More particularly, the described embodiments relate to methods, and systems for identifying files of a collaborative file storage system or a desktop file storage system having relevance to a first file. BACKGROUND [0002] In a collaborative file storage system, search engines use a variety of search techniques to present documents to users based on one or more search terms, which are provided, by the users. The relevance of search results relate closely to the search terms. Selection of a document from the search results in the search engine of a collaborative file storage system provides a list of documents related to the selected document. Users who like to read more about the related subject matter use the results suggested by the author or the search engine itself. Many authors suggest related documents that are very valuable to users also referred to as citations. The suggested list however is older than the selected document. For documents published after the publication date of the selected document, users have to rely on the search engine to provide a relevant list. The documents suggested by search engines are based on the search engine's algorithm. The search engine generally produces a large number of documents, which include some irrelevant results and are difficult to sort for relevant documents. Many suggested documents are not relevant to the user. Relevant results are not always provided. [0003] It is desirable to have methods and systems for providing an up-to-date list of documents (files) related to the selected document (file) relevant to the subject matter of the selected document in a collaborative file storage system or a desktop file storage system. SUMMARY [0004] One embodiment includes a method of identifying files of a file storage system having relevance to a first file. The method includes identifying a plurality of files within the file storage system, wherein the plurality of files each have a relationship with the first file, and wherein the file storage system allows sharing of the plurality of files between multiple users through a network. The method further includes generating, by a system server, a list of inquiries based on the plurality of files, providing, by the system server, the list of inquiries to at least one collaborator of the first file, receiving from the at least one collaborator at least one response to the list of inquiries, selecting a subset of the plurality of files based on the at least one response, and storing information related to the selected subset of the plurality of files for access if the first file is selected. [0005] Other aspects and advantages of the described embodiments will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, illustrating by way of example the principles of the described embodiments.

DETAILED DESCRIPTION [0017] The described embodiments are embodied in methods, and systems for providing a set of files to a user in a collaborative file storage system, where the set of files have relevance to the first file from a search or retrieval of a record identifying the first file. [0018] FIG. 1 is a block diagram of an embodiment of system 100 , a system of providing related files from a collaborative file storage system, where a collaborator is involved in selecting/ranking a subset of files. [0019] Enterprises create shared file systems for various business activities. A collaborative file storage system provides a platform for sharing files for teams of people working together. For at least one embodiment, the collaborative file storage system includes remote storage of a plurality of files, and allows sharing of the plurality of files between multiple users through a network. Users can upload files and share the files immediately without the need to email or transport using portable storage drives. In an embodiment, the shared files have read or read and write privileges. PubMed®, SharePoint®, Pike®, Google Doc®, Box.net®, Drop Box®, and desktop file systems such as Microsoft Window®, Apple Macintosh®, or Linux® are examples of collaborative file storage system. Collaborative file storage system is a file storage system among the members of an enterprise or group. The collaborative file storage system stores files of different formats not limited to word document, power point presentations, portable document format (pdf), and spreadsheets. In one embodiment of a collaborative file storage system, a user may contribute to the file system. In an embodiment, any user may edit a file similar to a wiki. In another embodiment, write privilege to a file may be assigned to a certain group of users such as team of authors or a team of people working on a project. [0020] For at least one embodiment, the collaborative file storage system includes a desktop file storage system for storage of the plurality of files at a desktop or a mobile user computer, and allows sharing of the plurality of files between multiple users through a network. In an embodiment, the shared files have read or read and write privileges. Microsoft Window, Apple Macintosh®, and Linux® are examples of personal computer operating systems that contain a desktop file storage system. Mendeley, Evernote, and Zotero are examples of desktop file storage systems that run in personal computer operating systems. A desktop file storage system is a file storage system running inside the operating system of a personal computer. The desktop file storage system stores files of different formats not limited to word document, power point presentations, portable document format (pdf), and spreadsheets. [0021] In one embodiment of a desktop file storage system, a user may contribute to the file system. In several embodiments, a first file is a file in the collaborative file storage system, a file whose URL was shared by the user on a social network, or a file on the disk drive of the user system, or a file on the internet, or a file on any other file system identified to generate a list of related files. The first file may be a recently added file to the collaborative file storage system, or identified due a large number of files added to the collaborative file storage system in the same subject matter, or identified automatically for a periodic update of related files, or identified by any other method. It is to be understood that for various embodiments, the first file and the related files includes at least one of a web page, a document, an article, a social profile, a message, a message thread, a conversation, a video file, an audio file, or a picture file. It is also to be understood that this is not an exhaustive list. [0022] At least some embodiments of the collaborative file storage system are updated constantly as users add files to the file storage system. As the number of files grows large, existence of the file may not be known to many users if relevant hyperlinks to other files are not created. Creating hyperlinks is a manual task and often few files are linked together in a collaborative file storage system. Search engines provide access to the files that are not linked. Examples of search engines for a desktop file storage system include X-1, Windows Search, and Apple Spotlight. [0023] Many collaborator/authors list references or citations in their files. The files referenced by collaborators/authors are generally more relevant than the machine generated references, but have a publication date earlier than the current file. Unlike machine generated references using an algorithm running on a computer, the judgment of human authors in selecting reference documents is uniquely valuable to other readers due to the author's intrinsic understanding and motivation to identify materials related to the file written by that author. In general, an author or expert has greater interest and more precise understanding of the subject matter compared to other readers. In the described embodiments, a collaborator is an author or a co-author or an expert on the subject matter or a team member or a person who is identified for correspondence related to the first file or listed in the metadata of the first file anyone who has write-privilege to the first file. [0024] Search engines list files that may be related to a first file that may be published before or after the first file has been published. When a file is selected from the search results, a set of possibly related files is generally presented by search engines. The list may not always be accurate. For example, when asked to evaluate the accuracy of the list of related files, an author of the first file or expert on the subject matter of the first file may not always concur with the relationship of all the files presented in the list of related files provided by the search engine. Therefore, lists of possibly related files produced by the search engines may contain some files that are actually related (true-positives) and some that are unrelated in practice (false-positives). The set of related files produced by a search engine are based on some criteria such as the number of hyperlinks a file has, common subject matter, and the frequency of certain phrases. The number of hyperlinks to a file is one of the criteria used by search engines to rank it in search results to make it visible to users searching for it. If a file has no hyperlinks, a file that is actually related may be missing from the list of related files presented by the search engine (false-negatives). The list of related files presented by a search engine can be improved by surveying an expert or author to recommend the related files and eliminate false-positives and false-negatives. The method of semi-automating the presentation of a list of related files using surveys is described in the embodiments. [0025] For at least one embodiment, a set of files related to the first file is identified in collaborative file storage system 110 by server 120 . In one embodiment, identifying in collaborative file storage system 110 includes server 120 identifying a set of files related to the first file and receiving the list of identified files. In another embodiment, identifying in collaborative file storage system 110 includes server 120 receiving the list of identified files. The set of identified files 110 can be the output of natural language search, or a text analysis, or from collaborative filtering, or any other search technique. The search can be based on a string of words, or a picture or a collaborator. The set of files is derived based on a relationship with the first file. The relationship can be any one of or some of author of the first file, author of the references cited in the first file, frequently used noun phrases, publication date later than the first file, a specific publication date, or a publication date after a specific date. Files published from an author tend to have common subject matter. Frequently used noun-phrases in the first file are also keywords for searching related files. However, noun phrases may change with technology or over a period. Many search engines may not have the intelligence to recognize the changing noun phrases over a period. In some embodiments, the full-text of the file is used for searching to yield more relevant related files. Files with publication date later than the first file are valuable as users are generally interested in recent updates. In an example, a search engine operating on server 120 uses Windows Search API to identify bibliography of post-publication updates to papers in the Microsoft Windows® desktop file storage system, based on noun phrases in full-text. [0026] In an example, a search engine operating on server 120 uses ENTREZ® API to identify bibliography of post-publication updates to papers in PubMed®, based on noun phrases in full-text. PubMed® is a free database of references and abstracts on life sciences and biomedical topics. ENTREZ® is a powerful search engine that allows users to search health sciences database at the National Center for Biotechnology Information website. The algorithm used to generate the search terms using ENTREZ® API automatically extracts noun phrases from a file using natural language processing tools and ranks them by the number of occurrences in the file compared to the number of occurrences on the web. In another embodiment, a search API such as FAST/SharePoint®, Google Search Appliance®, or Autonomy IDOL® may be used. In another embodiment, a search API such to Windows Desktop Search® or Apple Macintosh Spotlight Search®, or X1® search may be used. [0027] In an embodiment, citation-validation is used to generate the list of related documents 110 . Citation-validation is defined as search results from queries where the queries are present in one or more citations provided by the author. Citation-validated search terms improve the relevance of the search results compared to search terms that are not present in the citations. The citations can written by the same authors as the paper or written by different authors. [0028] For an embodiment, a server 120 generates a list of inquiries based on the set of files related to the first file. In an embodiment, the list of inquiries includes questions asking the collaborator whether the files are relevant to the first file, and the search terms used in keyword search or noun-phrase used to select the file. [0029] FIG. 2 shows example 200 , an inquiry generated using keyword search by desktop API in desktop file storage system or ENTREZ® API in PubMed®. The selection of keyword search results displays related files. Example 200 shows the related files from keyword searches. In example 200 , 202 is the title of the first file. The first question summarizes the inquiry about relevant files. 204 is a check box next to a related file selected by a search engine. 206 is the publication date of the related file. 208 is the search term used to identify the related file. 210 is an input box for the collaborator to enter the reason for the file being relevant. 212 shows the author who selected the profile as relevant. 214 shows the institution of the author. 216 shows the relationship tag, 218 shows the email address of the author, 220 shows the address and 222 shows the affiliation of the author. In one embodiment, the identity of the senders who selected each message thread is revealed to the user by displaying meta-data such as the sender's name, address, or contact information. [0030] FIG. 3 shows example 300 generated using PubMed® ENTREZ® API to obtain related citations in PubMed® and display the files published after the first file. In the described embodiments, a single ranked list of PubMed® papers that are related are derived from text-analysis of papers is referred to as PubMed® Related-Citations. For each word or term in each paper, a numeric weight is computed based on the number of times the word occurs in the paper and the number of papers that the term occurs in within PubMed®. The numeric-weight is used to find the most similar pairs of papers. 312 is the title of the document obtained from related citations. In another embodiment, Autonomy® or Google Search Appliance® indexes the collaborative files system and includes “automatic hyperlinks” or “related documents” functions similar to PubMed® “related citations.” [0031] For an embodiment, again referring to FIG. 1 , a collaborator 130 is notified of the list of inquiries generated by server 120 . In the described embodiments, the notification can be sent electronically. In an embodiment, the notification email contains a link to a webpage that contains the list of inquiries. In another embodiment, the email contains the text of the inquiries. In another embodiment, the notification is sent by an email or message on a social network such as Facebook® or instant message system. In another embodiment, the notification is sent from a web-based interface such as Jive®, or LinkedIn® or Google Docs®. The collaborator completes the inquiry by selecting one or more files related to the first file in the opinion of the collaborator, and sends the response to the server using any of the notification methods described above. Server 120 receives the response to the inquiry from the collaborator and processes the response. The response includes a selection of files related to the first file. In an embodiment, the response includes a ranked list of the related files, identifying the relevance of the related files to the first file. [0032] In an embodiment, files selected by the collaborator are ranked higher than the files not selected by the collaborator. A subset of the ranked files is selected. In another embodiment, all files selected by the collaborator 130 are selected. In another embodiment, a certain number of ranked files are selected. Server 120 creates a hyperlink between the first file and the subset of selected/ranked files in the collaborative file storage system. The hyperlink influences future search results of the engine when the first file or any of the subset of files is involved. Server 120 stores information about the subset of related files in a storage system 140 . The information includes one or more of hyperlinks to the related files, ranking of the files, the collaborator of the first file, and metadata of the files. In the described embodiments, hyperlinks are references to files that connect the users to another file or a portion of the file. In another embodiment, storage system 140 is a separate file storage system. When a user selects the file identifier ( 150 ) from search results or any other listing, server 120 retrieves information about the selected/ranked related files. In several embodiments, the user is presented with a list of information about the related files shown in FIG. 2 and FIG. 3 . In one embodiment, the identity of the collaborators who selected each file is revealed to the user by displaying meta-data such as the collaborator's name, institution, and qualifications. [0033] FIG. 4 is a block diagram of an embodiment of system 400 , a system of providing related files, where more than one collaborator provides input to selecting/ranking a subset of files. A set of files related to the first file 110 is identified in collaborative file storage system by server 420 . For at least some embodiments, the set of files is derived based on a relationship such as author, frequently use noun-phrases, and common subject matter with the first file. For an embodiment, a server 420 generates a list of inquiries based on the set of files related to the first file. In an embodiment, the list of inquiries includes questions asking the collaborators whether the related files are relevant to the first file as determined by the search engine. [0034] For at least one embodiment, the list of inquiries generated by server 420 is notified to the first collaborator 430 . In at least some of the described embodiments, a first collaborator is the author of the first file, an expert on the subject matter or a team member or anyone who has write-privilege to the first file. The list of inquiries is also notified to second collaborators 431 . In at least some of the described embodiments, the second collaborator is one or more collaborators other than the first collaborator. The first and second collaborators are notified electronically as described in conjunction with FIG. 1 . Server 420 receives responses from the first collaborator as well as the second collaborators. The response includes a selection of files related to the first file. In an embodiment, the response includes a ranked list of the related files, identifying the relevance of the related files to the first file. In an embodiment, files are ranked based on the number of selections from the first and the second collaborators. In an embodiment, the files selected by the first collaborator are ranked higher than the files selected by second collaborators. In another embodiment, all responses are ranked with the same weight. In another embodiment, a certain number of ranked files are selected. In another embodiment, all files selected by the first collaborator and the second collaborators are selected. [0035] For at least some embodiments, information about the selected/ranked files is stored in a storage system 140 . User selection of the first file identifier 150 from search results or any other listing is sent to server 420 . In several embodiments, server 420 retrieves information about the selected/ranked list of related files from the file storage system before presenting to the user shown in FIG. 2 and FIG. 3 . In one embodiment, the identity of the collaborators who selected each file is revealed to the user by displaying meta-data such as the collaborator's name, institution, and qualifications. [0036] FIG. 5 is a block diagram of an embodiment of system 500 , a system of providing related files, where more than one collaborator provides input to selecting/ranking a subset of files and more than one list of inquiries is generated. For this embodiment, one or more files related to a first file are identified by server 520 in a collaborative file storage system (similar to the description in conjunction with FIG. 1 ). A list of inquiries is generated by server 520 based on the files related to the first file. The list of inquiries includes questions asking the relevance of the related file to the first file. The list of inquiries is notified to a first collaborator 550 . A first response is received from first collaborator 550 by server 520 . The first response includes selection of files that are related to the first file in the opinion of the first collaborator 550 . In an embodiment, the first response includes a ranked list of the related files, identifying the relevance of the related files to the first file. A second list of inquiries is generated based on the first response. The second list of inquiries includes questions about the selection of the files related to the first file by the first collaborator. In an embodiment, the second list of inquiries includes one or more of the selection of related files by the first collaborator, the publication date, the abstract, the unique identification number, the search terms used to identify the related file or the noun-phrases used to identify the files, or the noun-phrases in the citation of the first file. [0037] For at least some embodiments, second collaborators 551 are notified electronically (by methods discussed in conjunction with FIG. 1 ) with the second list of inquiries. Server 520 receives the second response from second collaborators 551 and analyzes the second response. The second response further refines the machine generated search results. The second response includes a selection of files related to the first file. In an embodiment, the second response includes a ranked list of the related files, identifying the relevance of the related files to the first file. [0038] In an embodiment, server 520 generates a questionnaire based on identified files related to the first file 110 .

When a second search yields a plurality of search results containing the information identifying first file 650 , server 620 , retrieves the stored information about the subset of selected/ranked files and influences the ranking of the first file relative the search results when presenting the search results to the user. In one embodiment, the identity of the collaborators who selected each file is revealed to the user by displaying meta-data such as the collaborator's name, institution, and qualifications. Methods [0041] FIG. 7 is a flowchart that includes the steps of an example of a method of providing related files, where a collaborator is involved in the selecting/ranking a subset of files. In step 702 , the collaborative file storage system is searched to identify one or more files that are related to a first file. For at least some embodiments, the search is based on any of or all of natural language search, machine language search, text analysis, or collaborative filtering. For at least some embodiments, the collaborative file storage system is searched for keywords that are automatically generated by the server. The keywords may be the author/authors of the first file, frequently appearing words, authors of cited references in the first file, noun phrases based on subject matter, and title. In an embodiment, the search is conducted on the full-text of the file. In another embodiment, only the abstract and the title are searched. In an embodiment, only files published after the first file's published date are searched. In embodiment, the algorithm used to generate the search terms using ENTREZ® API automatically extracts noun phrases from the first file using natural language processing tools and ranks them by the number of occurrences in the file compared to the number of occurrences on the web. In one embodiment, the algorithm used to generate the search terms using desktop search API automatically extracts noun phrases from the first file using natural language processing tools and ranks them by the number of occurrences in the file compared to the number of occurrences on the desktop file storage system. In an embodiment, citation-validation is used to generate the list of related files to improve the quality and relevance of the search results. [0042] In step 704 , the server automatically generates a list of inquires based on the search results of step 702 to access the relevancy of the search result. The list of inquiries includes questions about each related file. In an embodiment, inquiries list the title of one or more files identified in the search, the publication date, and the search terms used to identify the file. Other embodiments may not list all the above items. FIG. 2 and FIG. 3 , show an example of the list of inquiries presented to collaborators. In step 706 , the list of inquiries is notified to at least one collaborator of the first file.

Web based interface is another method of notifying the collaborator. [0043] In step 708 , method 700 receives at least one response to the list of inquiries from the collaborators. The response includes a selection whether any of the files are relevant to the first file. If any of the files are relevant, a selection of the relevant file and optionally the reason for the file being relevant is received by the server. In an embodiment, the response includes a list of the related files, identifying the relevance of the related files to the first file. In step 710 , method 700 analyzes the responses from the collaborators. The related files are ranked based on the number of selections received from the collaborators. A subset of the ranked related files is selected. In an embodiment, all files selected by the collaborators are selected. In another embodiment, a certain number of ranked files are selected. In another embodiment, files receiving certain rank are selected. Method 700 creates a hyperlink between the first file and the selected/ranked subset of files. The hyperlink can influence the search results in the collaborative file storage system when the first file is involved. In step 712 , information about the selected/ranked files related to the first file is stored. The information about the selected/ranked files includes at least one of hyperlinks to the files in the collaborative file storage system, the rank of each file in the selected subset, metadata of the files. The information may be stored on the collaborative file storage system or any other storage system. [0044] Steps 702 - 712 are performed to generate a list of selected/ranked files that may be more relevant than the machine generated references. In an embodiment, steps 702 - 712 are performed once. In another embodiment, steps 702 - 712 are performed at certain fixed intervals. In another embodiment, events such as addition of a certain number of files or a manual intervention may trigger steps 702 - 712 . [0045] In step 714 , method 700 receives a selection of the first file identifier or information about the first file from a user. The file or information about the file may be selected from search results or from a list of files. The server retrieves the stored information about the selected/ranked files in step 716 . In several embodiments, information about the related files is displayed to the user in step 718 shown in FIG. 2 and FIG. 3 . In one embodiment, the identity of the collaborators who selected each file is revealed to the user by displaying meta-data such as the collaborator's name, institution, and qualifications. Steps 714 - 718 are performed when a user selects the first file for display. [0046] In an embodiment, each of the steps of method 700 may be a distinct step. In other embodiments, method 700 may not have all of the above steps and/or may have other steps in addition to or instead of those listed above.

Server system 1002 consists of on one or more servers connected to the network. Server system 1002 can be a single unit, distributed in various locations, or virtualized. Processor system 1004 may include any one of, some of, any combination of, or all of multiple parallel processors, a single processor, a system of processors having one or more central processors and/or one or more specialized processors dedicated to specific tasks. Also, processor system 1004 may include one or more Digital Signal Processors (DSPs) in addition to or in place of one or more Central Processing Units (CPUs) and/or may have one or more digital signal processing programs that run on one or more CPU. [0074] Memory system 1006 may include, for example, any one of, some of, any combination of, or all of a long-term storage system, such as a hard drive; a short-term storage system, such as random access memory; a removable storage system, such as a floppy drive or a removable drive; and/or flash memory. Memory system 1006 may include one or more machine-readable mediums that may store a variety of different types of information. The term machine-readable medium is used to refer to any medium capable carrying information that is readable by a machine. One example of a machine-readable medium is a computer-readable medium. [0075] In an embodiment, memory system 1006 stores code for search engine 1008 , code to identify plurality of files 1010 , code to generate a list of inquiries 1012 , and code to select/rank subset of plurality of files 1014 . Memory system 1006 stores code for search engine 1006 to search the collaborative file storage system for files related to a first file and returns the result to server system 1002 . In the described embodiments, the first file can reside in the collaborative file storage system 1020 , or collaborator system 1022 , or storage system for information related to selected/ranked subset of files 1024 or memory system 1006 or any other storage system. In an embodiment, the search engine searches the abstract of the file. In another embodiment, the search engine searches the entire file for keywords. The results from the search engine are ranked in order of relevancy. The relevancy may be the number of times the keyword appears in the file, and the number of hyperlinks. [0076] The keywords for searching related files are supplied by the code to identify plurality of files 1010 . The keywords may be all of or some of frequently used noun phrases, the author of the first file, the authors listed in the references cited in the first file, words from the title, publication date, words related to subject matter. Once the server receives the list of files related to the first file, an inquiry is automatically generated by code to generate a list of inquiries/questionnaire 1012 and sent to one or more collaborators. The list of inquiries is based on the search results. The inquiries include the relevancy of each of files listed as a related file to the first file, the reason for the file being related to the first file. Code to select/rank subset of plurality of files 1014 , selects a subset of the files from search results, stores information about the selected subset of files, and provides a hyperlink between the first file and the selected subset of files. Selection of files may also include ranking the files based on the number of selection from the collaborators. In an embodiment, responses from different collaborators can have different weight. Information related to the selected/ranked subset of files is stored. In an embodiment, the information related to the selected/ranked subset of files is stored on a storage system for information related to selected/ranked subset of files 1024 . In another embodiment, the information related to the selected/ranked subset of files is stored in memory system 1006 . In another embodiment, the information related to the selected/ranked subset of files is stored in the collaborative file storage system. In an embodiment, a hyperlink is created between the first file and the selected subset of files. The hyperlink influences the ranking of search results by the search engine when the first file is involved. [0077] Network 1016 is a network and/or combination of networks of devices that communicate with one another within an enterprise or on the Internet. User system 1018 is a user device connected to the network 1016 . User system 1018 selects a file from the collaborative file storage system. The file is selected from a search result or from a listing of files. Collaborative file storage system 1020 is a shared file storage system. All users can access the collaborative file storage system to read and in some cases contribute to the file system. In an embodiment, the collaborative file storage system includes a desktop file storage system. Collaborator system 1022 is a user system in the network. The collaborator system has read and write access to files in the collaborative file storage system. A collaborator of a file may be an author of the file, co-author of the file, an expert in the subject matter or a team member. [0078] An embodiment includes a programmable storage device (such as memory system 1002 ) readable by a machine (such as, processor system 1004 ), tangibly embodying a program of instructions when executed by the machine to perform a method of identifying files of a collaborative file storage system having relevance to a first file. The method includes identifying a plurality of files within the collaborative file storage system, wherein the plurality of files each have a relationship with the first file, and wherein the collaborative file storage system includes remote storage of the plurality of files, and allows sharing of the plurality of files between multiple users through a network. The method further includes generating, by a system server, a list of inquiries based on the plurality of files, providing, by the system server, the list of inquiries to at least one collaborator of the first file, receiving from the at least one collaborator at least one response to the list of inquiries, selecting a subset of the plurality of files based on the at least one response, and storing information related to the selected subset of the plurality of files for access if the first file is selected. [0079] Although specific embodiments have been described and illustrated, the described embodiments are not to be limited to the specific forms or arrangements of parts so described and illustrated.
