Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 単語間の関係を利用し、かつ表層的な表現に は依存せず、より適切なキーワードを抽出することので きる抽出装置、および、より適切な検索要求に基づく検 索を行なうことのできる検索装置を提供する。 【構成】 表現抽出部2は、データ入力部1から入力さ れた文書データ中の各テキストを形態素解析部14で解 析し、単語単位に分割した後、単語群抽出部15で単語 群抽出規則に基づいて、互いに関係を持ち得る複数の単 語を、その品詞などの情報とともに表現として取り出 す。表現抽出部2で抽出された表現は、関係抽出部3で 関係抽出規則に基づいて、関係が付与され、さらに、正 規化部4において正規化される。正規化部4で正規化さ れた関係表現は、入力された原データとともに記憶部5 に登録する。登録された原データは、関係表現を検索キ ーとして検索可能である。 (57) [Summary] [Purpose] Based on a more appropriate search request, and an extraction device that can use a relationship between words and that does not depend on surface expressions and can extract more appropriate keywords. A search device capable of performing a search is provided. [Structure] The expression extraction unit 2 analyzes each text in the document data input from the data input unit 1 by a morpheme analysis unit 14, divides the text into word units, and then a word group extraction unit 15 determines a word group extraction rule. Based on this, a plurality of words that may have a relationship with each other are extracted as an expression together with information such as the part of speech. The expressions extracted by the expression extraction unit 2 are given a relationship by the relationship extraction unit 3 based on the relationship extraction rule, and further normalized by the normalization unit 4. The relational expression normalized by the normalization unit 4 is stored in the storage unit 5 together with the input original data. Register with. The registered original data can be searched using the relational expression as a search key.
