Development of a search system for legal and technical documents using labeling of lexical network information

Abstract

The contents of laws and technical documents are difficult, the relationships between them are complex, and the number of laws and technical documents is increasing, making it difficult for users to find the necessary laws and technical documents. We propose a method to assist users in identifying necessary parts of legal and technical documents in a short time by using information such as the relationship between legal and technical documents. We created a network of legal and technical documents. In addition to the sentences that make up the documents and the words that make up the sentences, we added labels that group similar words together. This enables ordinary users who do not have expert knowledge of legal and technical documents to understand the structure of the documents and to grasp them systematically.
