Abstract

PURPOSE:To hold securely the contents of each sentence and to improve retrieval efficiency by collating information for retrieval which consists of structure information and element information on a sentence obtained by analyzing a retrieval inquiry sentence with information for retrieval obtained similarly from an identification sentence registered in a data base. CONSTITUTION:The identification sentence 1a supplied to an object 5 to be registered is inputted to a sentence analyzing means 3 through an input means 2, and information for retrieval obtained by analyzing the input sentence into structure information, keywords as element information, and connection phrases between keywords, and the object 5 are registered in the data base 8 in the form of a registered body 9a and information 9b for retrieval on the registered body 9a by using a registering means 6. When the data base 8 is retrieved with the retrieval inquiry sentence 1b, the information 9b for retrieval is collated by a retrieving means 7 with similarly obtained information 4 for retrieval on the inquiry sentence 1b. At this time, coincidences of not only keywords, but also connection phrases and modification relations are collated to perform retrieval efficiently.

First, the flow of registering an object 5 to which an "inquiry about product C from company A to company B" is added as the identification text 1a will be shown. The identification sentence 1a can be input using method 1, in which a list of possible phrases is displayed on the CRT, and a connecting phrase is selected from the displayed candidates (selection using a pointing device or using a function key). There is a method 2 in which the data is input by selecting the data (selection, etc.). The filler phrase candidates for Method 2 are based on filler phrases that are frequently used in identification sentences.
Display as shown. The identification sentence input from the input means 2 as described above is analyzed by the sentence analysis means 3. In the sentence analysis means 3, when analyzing the identification sentence input in method 1, it uses an independent word dictionary, an attached word dictionary, etc. to separate the keywords and the connecting phrases between the keywords, and then The relationship extraction process shown in Figure 3 is used for the relationship extraction process, and the relationship, keyword, and linking phrase information between the keywords (these are the search information for the registered object obtained from the identification sentence). 4)) On the other hand, when analyzing the input identification sentence using method 2, there is no need to separate the keywords and the connecting phrases between the keywords; All you need to do is perform the relation extraction process. Search information 4 possessed by the identification sentence extracted by the sentence analysis means 3
The object 5 to be registered is registered in the database 8 using the registration means 6. In the database 8, it is stored in the form of a registered object 9a and search information 9b for the registered object 9a. As described above, when registering an object according to the present invention, even if the identification sentence given to the object is entered as a natural sentence instead of a keyword, the keyword is extracted and the keyword connecting phrase is added. and dependency relationship information is also extracted and stored in the database. As another example of identification sentence 1a, “B
If the search information shown in FIG. ``Inquiry letter'' and ``Inquiry letter regarding product C from company B to company A''
In order to distinguish between the two, it is not necessary to provide a keyword with a connecting phrase, for example, "from company A 1" for the former and "to company A" for the latter.

Next, when searching the database 8 using the search interim statement 1b, the steps from inputting the search interim statement 1b to analysis are the same as those for registration. The retrieval means 7 performs a retrieval using the retrieval information 4 possessed by the retrieval statement resulting from the analysis and the retrieval information 9b of the registered object stored in the database. - For example, if you enter "Inquiry about product C from company B to company A" in the search statement, the search means 7 will search the search information contained in the search statement and the search information stored in the database. Verify with the actual information.

At the time of comparison, in accordance with the search information, not only a match of keywords but also a match of connecting phrases between keywords and a match of dependency relationships are checked. As a result, the search information that has a difference in expression due to rearrangement, for example, the search information extracted from the identification sentence "Inquiry text from company B to company A regarding product C", is changed from the above search makeshift sentence. It is the same as the search information you have. Furthermore, by having a synonymous phrase table for the connecting phrases, even if they have the same meaning but different connecting phrases, they can be compared as the same. Furthermore, in order to perform a search that retrieves related objects, it is possible to perform a matching algorithm by looking at dependency relationships and checking whether they agree even if there are deficiencies or redundancies. For example, the search information extracted from the identification text "Inquiry text from company B to company A" is related to the search information included in the above-mentioned search interim text. As described above, when searching for a matching sentence in the present invention, the matching sentence is a natural sentence, just as it is at the time of registration, even if it is a sentence that is different in expression from the identification sentence at the time of registration. Provides searchability.

Note that it is also possible to write the identification sentence and the search interim sentence in other languages.

Effects of the Invention As described above, by analyzing identification sentences and search intermediary sentences, search information consisting of keywords, linking phrases between keywords, and dependency relationships can be obtained, and at the time of a search,
By comparing the search information of the stored identification sentence with the search information of the input search query sentence, the search can be performed more easily than by a list of keywords or a mixed expression of keywords and AND and OR operators. This enables more efficient searches.
