Description

  The present invention relates to an information processing technique for issuing an electronic journal.

  Conventionally, academic papers have been published through paper-based academic journals. Recently, however, papers are generally published in electronic journals on the Internet.

  By the way, in many cases, a DOI (Digital Object Identifier) that is an identifier for uniquely identifying each paper is given to a paper published on the Internet. DOI is a universal code system for indicating the location of a paper published on the Internet, and the original location of the paper can be specified without being affected by a change in URL or the like.

  Specifically, the DOI is a code such as “10.1039 / j29710000797”, and can be assigned not only to the unit of books and magazines, but also to any unit such as chapters, papers, tables included in it. . By using this DOI, it is possible to access original data of a paper associated with the DOI.

When browsing original data of a paper using DOI, for example, crossref. In the Web page provided by org (Non-Patent Document 1), when a DOI is input into a text box for inputting a DOI and the search button is pressed, a URL associated with the DOI is acquired from the directory server, The original data of the paper can be accessed using the URL. In addition, the URL “http://dx.doi.org/10.1039/j29710000797” with the DOI added after the URL “http://dx.doi.org/” indicating the DOI directory server You can also access directly. Note that the directory server manages the DOI and the URL where the original data of the paper specified by the DOI is associated with each other. Also, crossref. org also manages a database in which attribute information such as papers is associated with DOI.
“Crossref.org”, [online], [search January 6, 2006], Internet <URL: http://mailserv.crossref.org/>

  By the way, as described above, it is common for papers to be published in electronic journals on the Internet, and researchers' paper writing and browsing environments have changed compared to when paper journals were published. ing. However, the accuracy of the cited references in each paper is the same as before the digitization, and the author's description is still trusted. Verification and correction on the editing and publishing side is very difficult from the viewpoint of human burden of verification burden and time of publication schedule.

  In view of such a situation, the present invention intends to provide a system capable of automatically confirming whether or not a document described as a cited document exists in a document. In particular, the existence of a link to an electronic journal etc. of a cited document is automatically confirmed, and if a link exists, the link is embedded in the document and published, and the cited document of a newly published paper is also published. Is intended to automatically accumulate

  In order to solve the above problems, an electronic journal system of the present invention extracts information relating to a cited document included in document data, and generates a search expression based on the extracted cited document information, and a search expression generation Using the search expression generated by the means, an identifier acquisition means for searching for a document-specific identifier from the storage means (database), and when the identifier acquisition means acquires the document-specific identifier, the acquired identifier is used. Link embedding means for generating link information for accessing the original data of the cited document and embedding the link information generated in the document data.

  Preferably, the information processing apparatus further includes a document information storage unit that stores an identifier unique to the document and attribute information indicating a journal name of the document in association with each other, and the identifier acquisition unit uses the search formula generated by the search formula generation unit. If the document information storage means is searched and the identifier cannot be obtained from the document information storage means, the identifier is searched using the storage means outside the system. The “storage means outside the system” is a storage means connected to the electronic journal system via a network. For example, crossref. storage means (database) managed by org or the like.

  At this time, when the identifier acquisition unit acquires the identifier using the storage unit (database) outside the system, the acquired identifier is associated with the attribute information of the cited document related to the identifier in the document information storage unit. It is preferable to further include document information storage means for storing.

  Preferably, an e-mail for urging the sender of the e-mail to confirm an error or the like when the document-specific identifier is not acquired by the receiving unit that receives the document data by e-mail and the identifier acquiring unit. And a confirmation means for transmitting. Furthermore, the document data is preferably a paper submitted to an electronic journal.

  The link generation method of the present invention is a method for generating link information in a cited document included in document data in an electronic journal system comprising a control means for controlling the operation or processing of the system, wherein the control means , Extracting cited document information included in the document data, generating a search expression based on the extracted cited document information, and using the generated search expression, the control means stores the document-specific information from the storage means (database). When the identifier unique to the document is acquired as a result of the search, and the search means generates link information for accessing the original data of the cited document using the acquired identifier, Embedding the generated link information.

  The program of the present invention causes a computer to execute each step of the link generation method of the present invention. The program of the present invention can be installed or loaded on a computer through various recording media such as an optical disk such as a CD-ROM, a magnetic disk, or a semiconductor memory, or via a communication network.

  A dedicated or general-purpose computer having all of the above-described apparatus configuration or a part necessary for carrying out the present invention can be applied as the electronic journal system 10. The electronic journal system 10 may be composed of a single computer or a plurality of computers distributed on a network.

  The document identifier server 20 includes, for example, a database server that manages storage means (database) that associates electronic paper attribute information with DOI, and a Web server that operates the database server to transmit and receive search results. It is prepared for. Each server may be composed of a single computer or may be composed of a plurality of computers distributed on a network.

  As the user terminal device 30, a portable terminal device including a general-purpose or dedicated computer or a mobile phone that can be connected to a network such as the Internet can be applied.

  FIG. 3 is a block diagram showing the main functional configuration of the electronic journal system 10. The electronic journal system 10 includes an accepting unit 70, a search expression generating unit 72, an identifier obtaining unit 74, a link embedding unit 76, and a disclosure unit 78. In addition, preferably, the document information storage unit 80 and the confirmation unit 82 are further included. For example, the control means 50 of the electronic journal system 10 executes a predetermined program stored in the reading storage means 54 or the external storage means 56 and causes the control means 50 to function as various function realization means. Functional means are realized.

  Preferably, the external storage unit 56 of the electronic journal system 10 includes a document information storage area 84 that stores attribute information of a previously cited document (electronic article) and DOI in association with each other, and an ambiguous search. And a dictionary information storage area 86 for storing dictionary information.

  The accepting unit 70 has a function of accepting submission of a paper to an electronic journal. Preferably, the author or the like of the paper attaches or pastes the electronic paper to the electronic mail and transmits the electronic mail from the user terminal device 30 to the electronic journal system 10, and the receiving means 70 attaches or attaches to the electronic mail. Receive the pasted electronic paper.

  The search expression generation unit 72 has a function of extracting a portion where a cited document is described from the electronic paper received by the reception unit 70 and generating a search expression for searching the DOI. For example, a full-text search is performed on the end peripheral part of an electronic paper, and a part where a cited document is described is extracted by detecting an item set such as “references” or “References”. Then, a search expression for searching the DOI is generated for each cited document described in the electronic paper. The search formula includes attribute information such as journal name, publication year, volume, issue, and number of pages. Any attribute information used for the search may be used as necessary.

  In addition, it is general that the cited references described in the paper are described according to a certain format for each journal. Therefore, by setting in advance form information for extracting attribute information for each journal, it is possible to acquire attribute information necessary for the search.

  The identifier acquisition unit 74 has a function of searching the storage unit (database) based on the search formula generated by the search formula generation unit 72 and acquiring a DOI that is a document-specific identifier. Preferably, first, the document information storage means 84 which is a locally managed database of the electronic journal system 10 is searched. Then, when the search result can be obtained in the document information storage unit 84, that is, when the information of the document related to the search formula is accumulated in the document information storage unit 84, the DOI is acquired from the document information storage unit 84. When the search result cannot be obtained in the document information storage unit 84, the document identifier server 20 outside the electronic journal system 10 is accessed, the database of the document identifier server 20 is searched, and the DOI is acquired. Thus, by first searching the local storage means (document information storage means 84) and attempting to obtain the DOI, it is possible to reduce the communication cost and traffic load and improve the total processing speed. it can.

  If a search result is not obtained even after searching the document identifier server 20, a search is performed by changing a part of the search formula (so-called fuzzy search). At this time, the search formula is changed using the dictionary information stored in the dictionary information storage means 86. For example, referring to the dictionary information storage means 86, the journal name in the search formula is changed from "Journal of International ..." to "Jour. Int ....". In addition, the type of attribute information to be searched may be partially replaced.

  The link embedding unit 76 generates link information (URL) for directly accessing the original data of the cited document based on the DOI acquired by the identifier acquiring unit 74, and the generated link information is included in the electronic paper. A function of embedding in the portion where the cited document is described is provided. If the identifier acquisition unit 68 cannot acquire the DOI, the link is not embedded.

  The publishing means 78 has a function of publishing an electronic paper on a Web site after the addition of the link information of the cited document to the electronic paper is completed. For example, an electronic paper may be uploaded to a web page of an electronic journal.

  When the identifier acquisition unit 74 acquires the DOI from the document identifier server 20, the document information storage unit 80 stores the acquired DOI and the document attribute information related to the DOI in association with each other in the document information storage unit 84. It has a function. As a result, it is possible to locally manage a document for which a DOI has been acquired in the past, and when the identifier acquiring unit 74 searches and acquires the DOI, the document information storage unit 84 can be used like a cache. . Since the documents cited in the paper are often concentrated on specific documents, managing the DOI once used locally leads to a significant improvement in processing efficiency.

  The confirmation unit 82 has a function for confirming whether or not there is an error in the description of the cited document with respect to the author of the electronic paper when the identifier acquisition unit 74 cannot acquire the DOI. For example, it automatically notifies the authors of electronic papers of e-mails stating that the DOI cannot be obtained with the description of the cited references that could not obtain the DOI and the description of the current cited references, and confirms typographical errors, etc. Prompt. At this time, it is preferable to use the transmission source of the email received by the receiving means 60 as the transmission destination of the email.

  The document information storage unit 84 is a storage unit (database) for storing a document-specific DOI and attribute information of the document in association with each other locally in the electronic journal system 10.

  The dictionary information storage means 86 stores the dictionary information that is referred to when the identifier acquisition means 74 performs a fuzzy search by changing a part of the search expression generated by the search expression generation means 72 when searching the DOI. It is a means to memorize. For example, associations between the official names and abbreviations of journals and associations between words and abbreviations are stored as dictionary information.

  FIG. 4 is a diagram showing an example of link information embedded in the electronic paper by the link embedding unit 76. FIG. 6A is a diagram showing the description of a cited document before link information is embedded. In this example, three documents a) to c) are cited. FIG. 5B is a diagram showing the description of the cited document after the link information is embedded. In the example shown in the figure, the DOI can be acquired for the two documents a) and c), and the DOI cannot be acquired for the document b). The link embedding unit 76 adds a predetermined character string (http://dx.doi.org/) to the acquired DOI (for example, 10.1039 / j29710000797) and accesses a URL or the like for accessing the original data of the document. A link information (for example, http://dx.doi.org/10.1039/j29710000797) is generated, and a predetermined format (for example, \ href [http://dx.doi.org /10.1039/j29710000797]) Therefore, the link information is embedded in the electronic paper.

  FIG. 5 is a flowchart illustrating an example of a processing procedure in the electronic journal system 10. First, the accepting means 70 of the electronic journal system 10 accepts submission of an electronic paper from the user terminal device 30 (S100). The search expression generation unit 72 extracts a part where the cited document is described from the accepted electronic paper and generates a search expression for searching the DOI (S102). Thereafter, the identifier acquisition unit 74 searches the DOI using the generated search expression. At this time, first, the document information storage unit 84 is searched to try to obtain the DOI (S104). If the DOI cannot be obtained by searching the document information storage unit 84, the document identifier server 20 is accessed and the storage unit (database) of the document identifier server 20 is searched (S106). When searching for a DOI, the dictionary information storage unit 86 is referred to as necessary to perform an ambiguous search. When the storage means (database) of the document identifier server 20 is searched and the DOI is acquired, the document information storage unit 80 stores the acquired DOI in the document information storage unit 84 in association with the attribute information of the document (S108). .

  When the identifier acquisition unit 74 can acquire the DOI, the link embedding unit 76 generates link information (URL) for directly accessing the original data of the cited document based on the acquired DOI, and describes the cited document of the electronic paper. The link information is added to the location (S110). When the identifier acquisition unit 74 cannot acquire the DOI, link information is not added to the cited document. Further, if necessary, an e-mail is transmitted to the author of the electronic paper, etc., and confirmation is made as to whether or not there is an error in the description of the cited document (S112). In this confirmation process, the cited documents that cannot obtain the DOI may be collectively notified to the author or the like.

  The electronic journal system 10 repeats the processing from S102 to S112 for all documents cited in the accepted electronic paper (S114). Then, after the processing is completed for all the cited references, the publication means 78 publishes the electronic paper with the link information embedded on the website (S116).

  Note that the steps can be executed in any order or in parallel as long as the processing contents do not contradict each other.

  The present invention is not limited to the above-described embodiment, and can be implemented in various other forms without departing from the gist of the present invention. For this reason, the said embodiment is only a mere illustration in all points, and is not interpreted limitedly.

  For example, in the present embodiment, an example in which link information is automatically embedded in a cited reference of an electronic paper submitted to an electronic journal has been shown, but not limited to an electronic paper, a report, electronic data of a book, and other documents Applicable to any document data cited.

  In the present embodiment, the electronic article is identified by using the DOI and the link information is generated. However, the generation of the identifier and the link information is not limited to that using the DOI. In the present embodiment, an example of automatically generating a link of a cited document in an electronic paper has been described. However, the present invention can be applied to a case where a digital object such as music or video data is cited in addition to the document.
