Abstract

PURPOSE:To enable easy and speedy registration work by abolishing retrieval keyword registration work so as to retrieve an electronic document with retrieval keywords extracted from both of a text information part and an image information part. CONSTITUTION:When the desired retrieval keyword to be registered is registered by an input device 1, it is registered on a storage device 4 by a retrieval keyword registration part 52 of an electronic file processor 5. When the electronic document is registered, the inputted electronic document is divided into the text information part and the image information part by a retrieval keyword extraction part 51. Then, each of information is resolved into words and temporarily preserved as keyword candidates. The retrieval keywords are automatically extracted from both of the text information part and the image information part, and only the retrieval keyword recognized in a retrieval keyword table is adopted among the temporarily preserved retrieval keywords and decided as the retrieval keyword. Then, it is registered on the storage device 4 by the retrieval keyword registration part 52.

(C2) A search keyword is automatically extracted from both the text information part and the image information part, and is recognized by the search keyword table standardized in the apparatus among the temporarily stored search keyword candidates. A search keyword determination function that determines only the search keywords that exist as search keywords. (C3) A function of registering the search keyword determined by the search keyword determination function in the storage device 4 by the search keyword registration unit 52. Next, the registration / retrieval operation in the electronic filing apparatus of this embodiment configured as described above will be described with reference to the flow charts shown in FIGS.

Note that FIG. 2 is a flow chart showing the flow of main processing when searching an electronic document by using search keywords extracted from both the text information section and the image information section, and FIG. 3 is a text information section and image information. FIG. 4 is a flow chart showing the flow of main processing when registering both search keywords of the department. FIG. 4 shows the main process when registering the search keywords automatically from both the text information part and the image information part. It is a flowchart which shows the flow of various processes. First,
An operation for searching an electronic document will be described with reference to FIGS. 1 and 2. Now, when the operator selects the electronic document search mode, a search keyword input screen is displayed on the CRT display device 3.

Next, the operator inputs the search keyword to be registered from the input device 1 with reference to this search keyword input screen. In this case, the keyword may correspond to either the text information section or the image information section.

Then, the keyword search unit 54 of the electronic file processing device 5 searches the search keyword file registered in the storage device 4, and the electronic document in which the keyword matching the keyword specified by the operator is registered. The name is displayed on the CRT display device 3.

If the electronic document in which the keyword matching the keyword designated by the operator is not registered, the fact is displayed on the CRT display device 3. Next, with reference to FIG. 1 and FIG. 3, an operation for registering search keywords in both the text information section and the image information section will be described.

Now, when the operator selects the search keyword registration mode, a search keyword registration screen is displayed on the CRT display device 3 and a search keyword table is displayed. This search keyword table is standardized in this device and can be customized. It is also used in the keyword determination process when automatically extracting search keywords.

Next, the operator registers the search keyword to be registered with the input device 1 with reference to this search keyword table. In this case, the keyword may correspond to either the text information section or the image information section.

Then, the search keyword registration section 52 of the electronic file processing device 5 registers the search keyword specified by the operator in the storage device 4 as a search keyword file. Next, with reference to FIGS. 1 and 4, an operation for automatically extracting and registering a search keyword from both the text information section and the image information section will be described.

Now, when the operator registers an electronic document, first, the electronic document input from the input device 1 or the auxiliary input device 2 is divided into a text information part and an image information part by the search keyword extraction part 51. It Then, the text information part is decomposed into word units using an existing natural language analysis technique or the like, and temporarily stored as a keyword candidate.

Further, the image information section is converted into a word corresponding to the image by using the image information / text information correspondence table standardized in the present apparatus, the existing pattern recognition technique, etc., and is used as a keyword candidate. It is temporarily saved.

Next, search keywords are automatically extracted from both the text information section and the image information section, and among the search keyword candidates temporarily stored as described above, the search keyword table standardized in the apparatus is used. Only recognized search keywords are adopted and determined as search keywords.

The search keyword automatically extracted by the search keyword registration unit 52 of the electronic file processing device 5 is stored in the storage device 4 as a search keyword file.
Be registered with.

As described above, in the electronic filing apparatus of this embodiment, not only is the search keyword manually registered, but it is also automatically extracted and registered from the electronic document. In this case, the automatic extraction is the electronic document. In addition to extracting the search keyword from the text information section, the search keyword is also extracted from the image information section.

Therefore, regardless of the contents in the storage device 4, if the user does not have to add the search keyword himself / herself, which is a troublesome task of registering the search keyword, which has been done by hand when registering an electronic document, is completely abolished. Therefore, registration work can be performed easily and quickly.

Further, since the search keyword is automatically extracted and registered from both the text information section and the image information section of the electronic document, a more accurate and reliable search keyword can be registered, and the electronic document which is the purpose of the electronic document can be registered. It becomes possible to search for in a short time.

[0037]

As described above, according to the present invention, the troublesome search keyword registration work manually performed when registering an electronic document can be completely eliminated, and the registration work can be performed easily and quickly. At the same time, a more accurate and reliable search keyword can be registered, and an electronic filing device that can search for an electronic document intended by the user in a short time can be provided.
