Ancient document unified logical retrieval method based on index relation

Abstract

The invention relates to an ancient document unified logical retrieval method based on index relation, in particular to the logical combination of any logical relations contained in an input text string extracted from text retrieval, and belongs to the technical field of document retrieval. The logical retrieval method concretely comprises the steps of constructing an index system, counting the number of times of a sentence appearing in a fixed sentence length, establishing corresponding rules for logical relations, extracting the logical relation contained in an input text string, and combining rules thereof; displaying results and outputting the six technical steps. According to the logical retrieval method, different retrieval requirements of the user can be satisfied based on the understanding for the logical relation, and user experience is greatly improved.

Description

technical field [0001] The invention relates to an index relation-based unified logical retrieval method for ancient documents, which belongs to the technical field of document retrieval. Background technique [0002] Ancient literature data is a kind of massive information storage. How can we obtain information that meets the needs of users through reasonable and fast retrieval, and use computers to automatically study different objects of ancient literature, discover some changes, and then obtain some valuable knowledge. Because, relative to the different cultures of different countries, there are also great differences in language. Therefore, it is very important to set up a specific search for ancient Chinese documents to lay the foundation for knowledge discovery. [0003] Most of the existing patents related to retrieval focus on the rapid retrieval of information on the Internet, but relatively few researches on the retrieval of ancient documents; for example, the ap...

Problems solved by technology

[0003] Most of the existing patents related to retrieval focus on the rapid retrieval of information on the Internet, but relatively few researches on the retrieval of ancient documents; for example, the application publication number: CN 105989030 A, a text retrieval method and device proposed by the applicant; In this patent, the text entered by the user is divided into words, each keyword is displayed, and then the user selects the keyword for retrieval, which only realizes the rapid retrieval of information on the Internet, but not for the rapid retrieval of ancient documents. Retrieve and conduct research analysis on various objects

[0004] For example, the application publication number: CN 105354325 A, a document retrieval and analysis system proposed by the applicant, the patent sets the basic retrieval module, which searches in the structured database; sets the extended retrieval module, the retrieval module The search is based on user requests combined with natural language processing; a multi-source integrated retrieval module is set up, which integrates multiple data sources in the patent database and cross-database retrieval by users; although the patent is more in line with user requirements through multi-faceted correlation output As a result, but the settings cannot be used for statistical analysis research on various objects of ancient documents
