Abstract
In order to provide a case search system in which a search case corresponding to the notation fluctuation of a word within a sentence is a learning object, a sentence constituting a search target case is divided into a plurality of words by a morphological analysis, and a synonym integration unit 20 converts a predetermined word group within the sentence based on the relationship between the plurality of words into a single word consisting of another language in a synonym relationship with the word group. Further, the predetermined word group within the sentence is converted to a sentence with words stored in the corpus and the sentence is integrated, and the search target case composed of the integrated sentence is vectorized by leaning.
Claims8
A case search method for searching a predetermined case from search target cases stored in a database, the case search method comprising the steps of:
- dividing a sentence constituting the search target case into a plurality of words by a morphological analysis;
- extracting a predetermined word group from the sentence based on relationships between the plurality of words;
- converting the predetermined word group into a single word composed of another language in synonym relationship with the word group;
- storing the word unified into a synonym by the converting in a corpus;
- integrating the sentence by replacing the predetermined word group within the sentence with the word stored in the corpus;
- vectorizing a search target case composed of the integrated sentence by learning,
- receiving a search keyword input by a user;
- calculating a feature vector characterizing the search keyword;
- and
- extracting a search target case similar to the search keyword based on the degree of similarity between the vectorized search target case and the search keyword indicated by the feature vector.
