Description

  The present invention relates to a document data display processing technique executed by a program installed in a computer. The present invention particularly relates to a control program and a computer that extract proper nouns from document data displayed by a computer and display proper nouns or information added to proper nouns together with document data.

  Here, proper nouns include not only names that are uniquely given to things or events such as names of people, places, and product names, but also nouns defined in a predetermined dictionary database.

  When a document is displayed on a computer, a proper noun in the document is extracted, a hyperlink to another document linked to the proper noun is set, and a search process using the proper noun is proposed. For example, a mechanism for supporting a new awareness of a user who is browsing a document has been proposed.

  In the first conventional method, the document provider extracts proper nouns contained in the document and sets necessary link information before the user requests to view the document. For example, in a web site that provides a document explaining the meaning content of a headword, such as an encyclopedia, a hyperlink is set in advance for a proper noun included in the displayed explanatory text, and the user selects it. , The Web page of another explanatory text having the proper noun as a headword can be referred to (see Non-Patent Document 1).

As a second conventional technique, a technique has been proposed in which proper nouns are extracted from a target document when a user requests to browse the document in order to cope with the tendency of increasing proper nouns to be extracted in a document. It was.
Wikipedia, http://en.wikipedia.org/wiki/, January 23, 2007

  However, in the first conventional method, the document provider side needs to perform proper noun extraction processing in advance for all documents that the user may view. Since the vocabulary of proper nouns is constantly increasing, it has become necessary to redo the proper noun extraction process in response to the increase in vocabulary even for document data that has been subjected to proper noun extraction processing in the past. For this reason, the technique of performing proper noun extraction processing in advance has a problem that the processing cost is wasteful.

  In the second conventional method, the proper noun extraction process is performed when the document data is requested by the user to deal with the increasing number of proper nouns. However, it is necessary to perform the proper noun extraction process before sending the document data. It was. However, the user's primary purpose is document browsing, and the service of extracting proper nouns to give the user awareness is only an auxiliary. In the second method, there is a problem that the processing time for proper noun extraction occurs before the user browses the document, and the response time for the user's browsing request deteriorates.

  Moreover, in the above two conventional methods, each system that provides a document needs to have a proper noun extraction processing function. For this reason, it is necessary to maintain the vocabulary database used in the proper noun extraction processing for each document providing system, and there is a problem that the total maintenance cost is required.

  An object of the present invention is to extract proper nouns in a document and present the user with additional information added to proper nouns without sacrificing the user's main performance of browsing the document. It is to provide a data processing technology that supports new awareness of users.

  The present invention is a program for causing a computer to execute the following processing.

  For example, a computer that executes the control program according to the present invention is interposed as a client between a document data providing apparatus that stores document data and a proper noun extraction processing apparatus. Then, the computer extracts the phrase included in the document information from the document information to be displayed on another computer, and determines the location of the related document information related to the document information based on the extracted phrase. The location of the related document information used for setting the link destination of the component that is specified and is displayed together with the document information without covering the display area of the document information is provided to the other computer.

  As a result, the proper noun extraction process is executed every time the user browses the document data, so there is no need to execute the proper noun extraction process on all the document data in advance, or to repeat the proper noun extraction process. Processing costs can be reduced.

  Moreover, since the proper noun extraction process is performed in parallel with the user browsing the document data, the response time of the document data display for the user is not deteriorated.

  Further, when the computer in which the present invention is executed is configured as a client via a document providing device and a proper noun extraction processing device, a proper noun extraction process for document data provided from a plurality of document providing devices is performed. It can be processed by two proper noun extraction processing devices. For this reason, the maintenance of the vocabulary of the dictionary database used for the proper noun extraction processing has only to be performed in one place, so that the cost of maintaining and maintaining the proper noun extraction processing function for each document provider can be eliminated.

  Further, according to the present invention, in the proper noun extraction process, the proper noun extracted from the text data is stored in the proper noun extraction history storage unit in association with the document identification information given to the text data. Further, prior to the proper noun extraction process, it is determined whether document identification information that matches the document identification information of the received text data is stored in the proper noun extraction history storage unit, and if there is matching document identification information, The proper noun associated with the document identification information can be the proper noun extracted by the proper noun extraction process.

  Thereby, the uniqueness of the document data is confirmed, and the cache processing of the proper noun extraction processing result is realized. It is no longer necessary to perform proper noun extraction processing for the same document data, and the processing cost can be further reduced.

  Further, according to the present invention, in the proper noun extraction history saving process, when the document identification information is not added to the received text data, the feature value of the text data is calculated, and the document identification information based on the calculated feature value is added. The proper noun extracted by the proper noun extraction process can be stored in the proper noun extraction history storage unit in association with the document identification information.

  For example, a feature value of document data is calculated by combining a plurality of methods such as document data size, hash value calculation processing using a hash function, and checksum calculation processing, and proper noun extraction processing is performed using this feature value. Document identification information is assigned on the device side, and cache processing of the processing result of proper noun extraction processing is realized.

  Thereby, the management cost for managing document identification information for each document data by the document provider can be reduced. Further, even when the document identification information is forgotten to be added to the document data, the document data can be identified, so that it is not necessary to perform the proper noun extraction process, and the processing cost can be reduced.

  In the proper noun display processing, the present invention converts the extracted proper noun into a configuration that displays in a predetermined form (guidance form) that guides the user operation, and displays the converted proper noun. can do.

  Thereby, the extracted proper noun can be displayed in a state in which a new awareness is presented to the user. For example, when the extracted proper noun is converted to a configuration with hyperlinks, the user is prompted to click on the link information set for the proper noun, and thus the detailed information on the proper noun is confirmed. Can do.

  In addition, when the extracted proper noun is converted into a configuration in which search processing using the search key is set, the user is given an opportunity to immediately execute the search processing using the proper noun as the search key. You can check related information of nouns.

  Furthermore, the present invention relates to a proper noun existing as a headword from text data using the dictionary database storing additional information of the proper noun in which the proper noun is defined as a headword in the proper noun extraction process, When processing for extracting additional information is executed, in the proper noun display processing, the extracted proper noun and additional information are received, and the proper noun and additional information, or information configured based on the additional information, It can be displayed on a display device.

  In addition to simply displaying proper nouns, more information can be presented to the user by presenting additional information associated with proper nouns.

  For example, useful information can be notified to the user by associating the classification information (company name / person name / product name) as additional information of the proper noun. For example, when the proper noun is a company name, its stock price, company logo mark, map information indicating the company location, etc. can be displayed, and useful information can be provided to the user.

  The present invention also provides a document data display processing system comprising a document providing server for storing document data, a proper noun extraction processing server having a dictionary database for storing predetermined proper nouns, and a client terminal having a display device. It is.

  The client terminal obtains the document data to be displayed from the document providing server, displays the document data on the display device, extracts all or part of the text data contained in the document data, and extracts the proper nouns from the text data. Send to server. The proper noun extracted from the text data received from the proper noun extraction processing server is displayed on the display device along with the document data. The proper noun extraction processing server extracts proper nouns existing in the dictionary database from the text data, and transmits the extracted proper nouns to the client terminal.

  The program according to the present invention can be stored in an appropriate recording medium such as a portable medium memory, a semiconductor memory, or a hard disk that can be read by a computer. It is provided by transmission and reception using various communication networks via the interface.

  According to the present invention, since proper nouns are extracted from document data every time a user views the document data, it is not necessary to extract proper nouns from all document data in advance, thereby reducing processing costs. it can.

  Further, since the proper noun extraction process is performed in parallel with the display process of the document data, it is possible to extract the proper noun each time it is displayed without deteriorating the response time in the display process.

  Furthermore, since document data provided by a plurality of document providing devices can be processed by a single proper noun extraction processing device, the maintenance cost of the dictionary database can be reduced.

  Therefore, the proper noun extraction processing for each browsing request can be realized without impairing the response of the display processing of the document data, and the user's awareness with significant information can be supported.
