  Next, FIG. 2 is an explanatory diagram functionally showing the configuration of the document search apparatus according to the embodiment of the present invention. In the figure, reference numeral 200 denotes an original document storage unit, which is a functional unit that holds a plurality of documents (hereinafter referred to as “original documents”) before conversion by a document conversion unit 201 described later. These original documents include a document including a table in at least a part of its body (the number of tables in the body does not matter). Note that these documents may have any format, and documents of various formats may be mixed.

  A document conversion unit 201 is a functional unit that converts each document in the original document storage unit 200 into a common format, for example, an XML format. Specifically, the document conversion unit 201 is an XML converter corresponding to each format of each document, and the converted XML document output from the document conversion unit 201 is held in the search target document storage unit 202. . The original document before conversion in the original document storage unit 200 and the converted XML document in the search target document storage unit 202 can be in a one-to-one correspondence (for example, in the converted document). Gives the same file name as the document before conversion).

  Reference numeral 203 denotes an input / output unit that accepts input of search conditions as a basis of search by a document search unit 204 described later from the user, a search result list created by a search result aggregation unit 205 described later, This is a functional unit that displays the text of the linked original document on the screen.

  A document retrieval unit 204 retrieves a document that satisfies the search condition accepted by the input / output unit 203 from each document converted by the document conversion unit 201 held in the search target document storage unit 202. It is a functional part. The document search unit 204 can narrow down the matching documents by limiting to the appearance position of a character string or a numerical value, such as a document including a value in a certain field of a table in the document.

  Reference numeral 205 denotes a search result aggregating unit that functions to create a search result list as shown in FIG. 3 instead of the conventional search result list shown in FIG. 8 on the basis of the conforming document searched by the document search unit 204. Part.

  The search result list in FIG. 3 is a list in which records that match the search conditions are further extracted from the table in the matching document, and the values of the key items (fields having unique values) are listed. For example, “measurement result 1.jtd” in FIG. 6 and “measurement result 2.jtd” in FIG. 7 were obtained as documents including the numerical value “5.0” in the “voltage” field. In the case where an XML document corresponding to the document is obtained), the search result aggregating unit 205 first uses the record extracting unit 205a to record from the table in each document a value including “5.0” in the “voltage” field. Then, a record of “resistance B” of “measurement result 1.jtd” and a record of “resistance D” of “measurement result 2.jtd” are extracted.

  Next, the search result aggregation unit 205 uses the field extraction unit 205b to extract the designated field of the record extracted above. In the example of FIG. 3, as a result of the key item (only) being specified as this field, the character strings “resistance B” and “resistance D”, which are the values of the key items of the above records, are extracted.

  Then, the search result aggregating unit 205 further uses the result list creating unit 205c to add the extracted document to “resistor B” and “resistor D” (exactly, the XML that is the source of extraction). A table such as FIG. 3 is created by associating “measurement result 1.jtd” and “measurement result 2.jtd”, which are names of original documents corresponding to the document, and embedding a link to each document. Create In the figure, the link is represented by an underline. For example, by clicking “measurement result 1.jtd”, the viewer is activated to display the text of “measurement result 1.jtd” in the original document storage unit 200. it can.

  FIG. 4 is a flowchart showing the procedure of the document search process in the document search apparatus according to the embodiment of the present invention. Prior to the start of the illustrated process, each document in the original document storage unit 200 is converted to the XML format by the document conversion unit 201 and stored in the search target document storage unit 202.

  When the input / output unit 203 detects an input of a document search instruction from the user (step S401: Yes), the document search unit 204 that has received the instruction from the input / output unit 203 uses the search condition input together with the search instruction. A suitable document is searched from the search target document storage unit 202 (step S402).

  Next, the search result aggregating unit 205 notified of the conforming document from the document retrieving unit 204 uses the record extracting unit 205a to extract a record that meets the retrieval condition from the table in each document (step S403). Further, the field extraction unit 205b extracts only the fields designated in advance from these records (step S404), and the result list creation unit 205c then retrieves the search result list including the values of each field and the link to the extraction source document. Is created (step S405). Then, this list is transferred from the search result aggregating unit 205 to the input / output unit 203 and displayed on the screen as shown in FIG. 3 (step S406).

  According to the embodiment described above, when only documents that include a certain character string or numerical value as a value of a certain field in a table in a document are searched, the search result list includes records that match the search condition (exactly Is displayed in detail up to the required field value of the record. In other words, since the conforming parts in the conforming document are presented in a list, the user does not need to open the conforming documents one by one and confirm the conforming part as in the conventional art. Of course, even when it is necessary to check the conforming portions one by one, since the link to the original document is embedded in the result list, the text of the target document can be viewed at high speed.

  In addition, since the search is performed not on the original document directly but on the XML document converted from the original document, it is possible to perform a high-speed and leak-free search across various types of documents.

  In the above-described embodiment, only the key items in the record that meet the search condition are displayed as a list, but any number of fields may be displayed. For example, FIG. 5 shows a display example when the field is not particularly specified (the entire matching record is displayed). However, if the number of fields becomes too large, it will be difficult to see the search results. For example, even if the priority is given to each field with the key item at the top, and the higher the order, the more it will be placed on the left side of the screen. Good. This priority may be specified by the user when inputting search conditions or displaying a result list, or may be determined automatically or mechanically by some algorithm.

  In the above-described embodiment, there is no problem because the table format in the search target document is completely the same. For example, “measurement result 1.jtd” in FIG. If there is a “Manufacturer” item, and “Measurement result 2.jtd” in FIG. 7 has a “Measurement date” item in addition to “Voltage” and “Current”, and some fields are not common. , Only the values of fields common to all or at least many of the relevant documents may be displayed. That is, in this example, the “manufacturer” item and the “measurement date” item are ignored, and only the resistance value and the current value are displayed as a result list.

  As described above, according to the document search device, the document search method, and the document search program according to the present invention, when a search is performed on an electronic document including a table in the text, the search result is sent to the user. It can be presented in an easy-to-understand manner.

  The document search method described in the present embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. This program is recorded on a computer-readable recording medium such as the hard disk 105, the flexible disk 107, the CD-ROM, the CD-RW 109, the MO, and the DVD, and is executed by being read from the recording medium by the computer. The program may be a transmission medium that can be distributed via a network such as the Internet.

  As described above, the document search apparatus, the document search method, and the document search program according to the present invention are useful for searching an electronic document including a table in the text. This method is suitable when you want to know the values of other fields in the record that contains the data in the field rather than the document itself that contains the specified field.
