A display unit for displaying the search result, and the data search unit collates the attribute information of each document data when searching the document data, and at least one of the designated search word or the search related word On the other hand, document data corresponding to the attribute information in a search range designated in advance is extracted.

  According to this, when a designated search word or a search related word is set, in addition to searching the document data based on whether or not the set word is included in the document data, the search is performed based on the attribute information of each document data. Document data is searched by narrowing the range. By performing data search using the attribute information of document data in this way, fine data search with a narrowed search range becomes possible. In other words, the search results are such that some or all of the unnecessary information has been eliminated, so that, for example, a document created at a necessary place or at a necessary era can be accurately and easily acquired, and the acquisition time can be obtained. This shortens the convenience of data retrieval.

  As the attribute information of the document data here, at least one of a creation date, a creator, and a registered database name associated with the document data in advance can be used.

  In this case, it is possible to have a related information list in which the search range is set for each of the designated search words or the search related words, and a means for editing the related information list.

  The display unit includes a field in which the designated search word is designated, a field in which the search range of the designated search word is designated, a field in which the search related word is designated, and a search range of the search related word. A setting screen having a field for specifying can be displayed.

  The display unit may display a search result obtained by classifying document data including the designated search word or the search related word for each of the designated search word or the search related word.

  The display unit can display a search result to which the search range is added for each document data including the designated search word or the search related word.

  In addition, the display unit can display a search result obtained by classifying document data including the designated search word or the search related word for each search range.

  In order to solve the above problem, the data search program of the present invention includes a search procedure for searching document data including a specified search word or a search related word corresponding to the specified search word from a plurality of document data, and the search result. A display procedure for displaying the document, and when the search is performed to search the document data, the search procedure compares attribute information of each document data, and at least one of the designated search word or the search related word. The document data corresponding to the attribute information is extracted in the search range specified for.

  The data search method of the present invention also includes a search step for searching document data including a designated search term or a search related word corresponding to the designated search term from a plurality of document data, and a display for displaying a search result of the search step. The search step, when searching the document data, collates the attribute information of each document data, and within the search range specified for at least one of the specified search word or the search related word Document data corresponding to the attribute information is extracted.

  According to the present invention, it is possible to realize a data search technique that is more convenient for acquiring necessary information from document data.

  An embodiment of a data search apparatus to which the present invention is applied will be described with reference to the drawings. FIG. 1 is a diagram illustrating a configuration of a data search apparatus according to the present embodiment.

  As shown in FIG. 1, a data search apparatus for searching document data including information required by a user is a designated search word (hereinafter referred to as a keyword) or a search related word corresponding to a keyword (hereinafter referred to as a keyword related word). A data search unit 10 that searches document data including a plurality of document data, and a display unit 12 that displays search results of the data search unit 10.

The data search unit 10 applied to the data search apparatus of the present embodiment collates the attribute information of each document data when searching for document data, and is specified for at least one of keywords or keyword related words. The extended search control unit 14 extracts document data corresponding to the search range. As a result, it becomes more convenient to accurately acquire necessary document data from the document data. Here, the creation date, creator, registered database name, site, etc. associated with the document data in advance as the attribute information of the document data will be described in more detail. As shown in FIG. 1, the data search apparatus uses a digital engineering technique using a computer 16 and a database 18 connected to the computer 16.

  The computer 16 includes an input unit 20 for inputting a keyword and the like, a display unit 22 for displaying a keyword or a keyword-related word or a search range set for the keyword, and a related item in which a search range is set for each keyword or keyword-related word. A related information list construction unit (hereinafter referred to as a list construction unit 24) that constructs an information list, a data retrieval unit 10 that retrieves document data including keywords or keyword-related words from a plurality of document data in the database 18, and a data retrieval unit A display unit 12 that displays ten search results is mounted. However, each component may be mounted on another computer connected to the computer 16 and distributed on the network.

  The database 18 includes a document database 26 that stores a plurality of document data to be searched, and a related information database 28 that stores a related information list. The document database 26 stores a plurality of document data as search targets. The related information database 28 stores a related information list in which keywords, keyword related words, search ranges, comments, classifications, and the like are described in association with each other. The document database 26 and the related information database 28 may be distributed on the network.

  The input unit 20 mounted on the computer 16 includes a keyboard and a mouse. The input unit 20 is input with keywords or keyword-related words corresponding to necessary information intended by the user, and search ranges set for them. The search range here is a range determined by, for example, document creation date and time, registration destination database name, document creator, and the like. Further, the input unit 20 receives a comment and a classification to be displayed on the search range setting screen. The comment is a message for allowing the user to easily understand the set search range. The classification is, for example, a similar word or synonym used as a keyword related word. Note that the input unit 20 also has a function of capturing a keyword or the like input from a user terminal 32 connected to the computer 16 via the network 30.

  The display unit 22 displays information (for example, keywords, keyword related words, search range) input to the input unit 20 on the screen. The display unit 22 has a setting field having a column for specifying a keyword, a column for specifying a keyword search range, a column for specifying a keyword-related word, and a column for specifying a search range for a keyword-related word. Display the screen. Further, the display unit 22 extracts specified information (for example, keywords, keyword related words, search range) from the related information list of the related information database 28 in accordance with a command from the input unit 20 and displays it on the screen.

  The list construction unit 24 reads the related information list from the related information database 28 and reconstructs it. The related information list here describes a keyword, a keyword related word associated with the keyword, a search range associated with at least one of the keyword or the keyword related word, and the like. For example, when information such as a keyword, a keyword-related word, and a search range set for the keyword is newly input from the input unit 20 via the setting screen of the display unit 22, the list construction unit 24 displays the input information in the related information list. Add to. The list construction unit 24 corrects the related information list when an instruction to change information such as a search range is input from the input unit 20 via the setting screen of the display unit 22. That is, the list construction unit 24 has a function of editing the related information list in response to a command from the input unit 20.

  The data search unit 10 is based on a database search unit 34 that extracts document data from the document database 26 based on keywords or keyword-related words specified via the setting screen of the display unit 22 and a related information list in the related information database 28. And an extended search control unit 14 that extracts document data from the document database 26.

  The database search unit 34 extracts document data including the keyword or keyword-related word from the document database 26 by determining whether character data matches or does not match the keyword or keyword-related word.

  The extended search control unit 14 operates in conjunction with the database search unit 34 and complements the search function of the database search unit 34. That is, the extended search control unit 14 collates the attribute information of each document data in the document database 26 when the database search unit 34 searches the document data. Then, the related information list is read from the related information database 28, and the document data whose attribute information falls within the search range set in the related information is extracted. For example, when the database search unit 34 searches the document data, the extended search control unit 14 specifies a search target database (for example, the document database 26) from a plurality of databases based on the registered database name described in the related information list. Further, based on the time range (for example, 1995 to 2000) of the related information list, the document data whose creation date falls within that time range is extracted. Further, based on the subject range (for example, Company A) of the related information list, the document data corresponding to the creator within the subject range is extracted.

  In short, the database search unit 34 searches by referring to the description content of the document data based on the keyword or the keyword-related word, whereas the extended search control unit 14 uses attribute information previously associated with the document data. Search for. By using both the search function of the database search unit 34 and the search function of the extended search control unit 14, document data including necessary information of the user is searched from the document database 26. As the attribute information of the document data, information automatically associated with each document data by the file management function of the operating system installed in the computer 16 can be used, or information intentionally associated with each document data is used. May be.

  The display unit 12 displays a list of search results of the data search unit 10 on the screen. For example, the display unit 12 displays a search result obtained by classifying document data including a keyword or a keyword-related word for each keyword or keyword-related word according to the search result output from the data search unit 10. Further, the display unit 12 can display a search range added to each document data including a keyword or a keyword-related word. Further, the display unit 12 can display the document data including the keyword or the keyword-related word by dividing each search range.

  The operation of the data search apparatus configured as described above will be described with reference to FIGS. FIG. 2 is a flowchart showing the procedure of the data search method of this embodiment. This procedure is broadly divided into phases (S1, S2) for building a related information list and phases (S3 to S7) for searching for information required by the user.

<Related information setting process: S1>
In this step, when a keyword corresponding to the user's necessary information is input and specified, a keyword-related word is selected and a search range to be set for at least one of the keyword or the keyword-related word is set. FIG. 3 shows a setting menu for setting keywords or related information. First, a keyword (for example, “carriage”) corresponding to user's necessary information is specified in the input field 50. A search range is defined in the column 52 for the keyword “carriage”. In the column 52 of FIG. 3, blanks are set which mean that the entire range is searched without limiting the search range. Note that blanks may be set if there is no designation for other fields. A comment is defined in the column 54 for the keyword “carriage”. Characters or commands specified in such a setting menu are input via the input unit 20.

  When the search button 56 in the setting menu is clicked, the related information list in the related information database 28 is referred to. Then, for example, a keyword-related word previously associated with the keyword “carriage” and its related information are extracted and displayed in a related information display area (for example, display areas 58 and 60). The display area 58 shown in FIG. 3 includes a display field 62 for the keyword-related word “E block” associated with the keyword “carriage” in the past, a display field 63 for the keyword-related word classification “synonyms”, and the keyword. A display field 64 for a search range “before 1995” set as a related term and a display field 66 for a comment “term before 1995” that easily recalls the search range are provided. The display area 60 is set in the display field 68 for the keyword-related word “Comb” previously associated with the keyword “carriage”, the display field 70 for the classification of the keyword-related word “synonyms”, and the keyword-related word. The display field 72 of the search range “Before 2000 AND Party A” and the display field 74 of the comment “Terms before 2000 at the Site A” that easily recall the search range.

  After referring to the display areas 58 and 60, the user clicks an add button 76 in the setting menu to newly associate a keyword-related word with the keyword “carriage”. When the add button 76 is clicked, a display area 78 is additionally displayed. The display area 78 shown in FIG. 3 includes an input field 80 for a keyword-related word “comb” associated with the keyword “carriage”, an input field 82 for designating the keyword-related word classification “synonyms” from the pull-down menu, and It has an input field 84 for a search range “O-site” set as a keyword-related word, and an input field 86 for a comment “term before 1995” that easily recalls the search range. Then, after entering the respective fields in the display area 78 and clicking the registration button 90 in the setting menu, the contents of the display area 78 are added to the related information list in the related information database 28 by the list construction unit 24. Similarly, when the contents of the display areas 58 and 60 are changed, the related information list is updated.

  Note that the keywords or keyword-related words shown in FIG. 3 are associated with each other in the related information list. For example, FIG. 4 shows a display example when “comb” is entered in the keyword input field 50 after the association work described with reference to FIG. As shown in FIG. 4, when the keyword “comb” is entered in the input field 50 and the search button 56 is clicked, the related information list in the related information database 28 is referred to. Then, based on the related information list, the display unit 22 displays the search range “B site” set for the keyword “comb” in the column 52 and the comment “B site term” in the column 54. In the display area 58, the keyword-related word “carriage” previously associated with the keyword “comb” is displayed in the display field 62. Further, a comment “common term” associated with the keyword-related word “carriage” is displayed in the display field 66. The search range display field 64 and the classification display field 63 in the display area 58 of FIG. 4 are displayed blank. Similar to the case of FIG. 3, a term or a search range associated with the keyword “comb” can be designated in each column of the display area 78.

<Related information registration process: S2>
Register the contents associated with the keyword in the related information list. For example, after defining or correcting the keyword-related words associated with the keyword or the search range thereof via the setting screen of FIG. 3 or FIG. 4, the registration button 90 is clicked. When the registration button 90 is clicked, the list construction unit 24 constructs or modifies the related information list based on the contents defined or modified via the setting screen of FIG. 3 or FIG. Note that when the cancel button 91 on the setting screen in FIG. 3 or FIG. 4 is clicked, the content defined or modified via the setting screen is not registered, and this process ends. 3 and FIG. 4, the user can interactively construct or modify the related information list, so that the related information (for example, keyword related words and search range) of the keyword can be easily set.

<Keyword designation process: S3>
When searching for necessary information, the user designates a keyword corresponding to the necessary information. For example, FIG. 5 is a display example of a search input screen. As shown in FIG. 5, the search input screen has an input field 94 for specifying a keyword. A keyword (for example, “E block”) is input to the input field 94 via the input unit 20.

<Specifying search range for keyword: S4>
A search range is designated for the keyword “E block” designated in step S3. For example, when the keyword “E block” is entered in the input field 94 of the search input screen, the display unit 22 refers to the related information list in the related information database 28. Then, as shown in FIG. 5, based on the registered contents of the related information list, comments (for example, “pre-1995 term” and “not set”) associated with the keyword “E block” are displayed in the related information setting menu 98. Is displayed. The comment here is displayed obliquely below the keyword “E block” in consideration of user convenience. The user selects a desired comment, for example, “terms before 1995” from among the displayed comments. That is, for the keyword “E block”, the search range “before 1995” corresponding to the comment “term before 1995” is designated. Therefore, in this example, when searching for necessary information based on the keyword “E block”, the search range is narrowed down to document data before 1995. If the comment “do not set” is selected instead of the comment “term before 1995”, the entire document data is searched when searching based on the keyword “E block”. If related information (for example, a search range) has not been associated with the keyword “E block” in the past, the related information setting menu 98 is not displayed. A display example in which the search range is set for the keyword “E block” is shown in the lower part of FIG.

<Extended search setting process: S5>
When searching for necessary information, in addition to the keyword and the search range set for the keyword, the keyword-related word and the search range set for the keyword-related word are additionally specified. For example, FIG. 6 is a display example of a keyword related word and search range setting screen. When the search expansion button 96 on the setting screen is clicked, the display unit 22 refers to the related information list in the related information database 28. Then, as shown in FIG. 6, the keyword related words (for example, “carriage” and “Comb”) associated with the keyword “E block” are displayed on the selection menu 100 based on the registered contents of the related information list. When a keyword-related word is displayed, the classification of the keyword-related word (for example, “same” meaning a synonym) is also displayed. Then, the user selects a desired keyword related word “Comb” among the keyword related words being displayed.

  When the keyword-related word “Comb” is selected, comments previously associated with the keyword-related word “Comb” (for example, “Terms before 2000 on the Site A” and “Not set”) are displayed on the setting menu 102. The user selects a desired comment, for example, “terms before 2000 on the A site” from among the displayed comments. That is, for the keyword “Comb”, a search range “AND 2000 site before 2000” corresponding to the comment “Terms before 2000 on Site A” is designated. Therefore, in this example, when searching for necessary information, the keyword related word “Comb” and the keyword related word are set in addition to the keyword “E block” and the search range “term before 1995” set for the keyword. The search range “AND site before 2000” is set. That is, when searching based on the keyword-related word “Comb”, document data belonging to the site A and document data created before 2000 are searched. If the comment “Not set” is selected instead of the comment “Terms before 2000 on the Site A”, all of the document data is searched when searching based on the keyword related term “Comb”. 5 and FIG. 6, the user can easily specify keyword related information (for example, keyword related words and search ranges).

<Search process: S6>
Necessary document data is searched based on the related information list set in step S4 or step S5. For example, when the search button 104 in FIG. 6 is clicked, the data search unit 10 is set to the keyword “E block” and the search range “before 1995” set to the keyword, and the keyword related word “Comb” and the keyword related word. The document data is searched from the document database 26 based on the search range “Terms before 2000 at Site A”.

<Search result display process: S7>
A list of the results retrieved in the step S5 is displayed on the display unit 12. FIG. 7 is a display example of search results. As shown in FIG. 7, the display screen displays a search result display area 108 based on the keyword “E block” and the search range “before 1995” set for the keyword, the keyword related word “Comb”, and the keyword related A search result display area 110 based on the search range “terms before 2000 on the site A” set for the word is included. That is, the search results are displayed by being classified into the keyword “E block” and the keyword related word “Comb”. However, not limited to this display form, a search range “before 1995” or a search range “terms before 2000 on the Site A” is added to each document data including the keyword “E block” or the keyword related word “Comb”. Search results. Further, it is possible to classify document data including the keyword “E block” or the keyword related word “Comb” into the search range “before 1995” or the search range “terms before 2000 on the A site” and display the search results. The user acquires necessary information with reference to the search result.

  According to the present embodiment, when keywords or keyword-related words are set, in addition to searching the document data based on whether or not the set words are included in the document data, attribute information (for example, creation) of each document data Document data is searched by narrowing the search range based on the date, creator, and registered database name. By performing data search using the attribute information of document data in this way, fine data search with a narrowed search range becomes possible. In other words, the search results are such that some or all of the unnecessary information has been eliminated, so that, for example, a document created at a necessary place or at a necessary era can be accurately and easily acquired, and the acquisition time can be obtained. This shortens the convenience of data retrieval.

  For example, if the meaning of a keyword or keyword-related word changes over time, or if the meaning varies depending on the region, a word search using only the keyword or keyword-related word will result in something other than the document data intended by the user. Unnecessary document data is also extracted. Also, when companies share each other's database due to mergers, etc., even if words that represent the same meaning are used in different words in each company, word search is performed using only keywords and keyword-related words. Then, unnecessary document data is extracted. More specifically, one company refers to a part as A, but another company refers to the part as B and associates A with another part. Unnecessary document data is extracted by performing a word search. In this regard, according to the present embodiment, by narrowing down the search range of data search using attribute information of document data, for example, necessary information can be accurately obtained from document data created at a required place or a required era. Searchable.

  As described above, the data search apparatus to which the present invention is applied is applied according to the present embodiment, but the present invention is not limited to this. For example, the number of search ranges set for keywords, the number of keyword-related words, and the number of search ranges set for keyword-related words can be increased as necessary. Moreover, although the example which set the site and the date as a search range was demonstrated, an e-mail or a technical field etc. can also be added to a setting. In addition, when a person name is set as a keyword, a condition for changing the person name can also be set in the search range.

  Moreover, as shown in FIG. 1, although each function was divided and demonstrated, it can implement | achieve as a computer program which mounted each function. That is, the data search program according to the present embodiment causes a computer to execute a search procedure for searching document data including a keyword or a keyword-related word from a plurality of document data, and a display procedure for displaying a search result. When searching document data, the attribute information of each document data is collated, and the document data whose attribute information falls within the search range specified for at least one of the keyword and the keyword-related word can be extracted. .

It is a figure which shows the structure of the data search device of one Embodiment to which this invention is applied. It is a flowchart which shows the procedure of a data search method. It is a display example of a setting menu for setting a keyword or related information. It is another example of a display of the setting menu of the search range which sets a keyword or its related information. It is a display example of a search input screen for setting a keyword or its related information. It is a display example of a setting screen for keyword related words and search ranges. It is a display example of a search result.
