Embodiment 1

[0062] Embodiment 1: as figure 1 , 2 As shown, a unified logical retrieval method for ancient documents based on index relations, including the following steps:

[0063] 1) Build an index system:

[0064] read text;

[0065] Establishing a first index table, the first index table includes a document number and a document name corresponding to the document number;

[0066] Establishing a second index table, the second index table includes different characters in all documents and in which documents the character appears;

[0067] Establishing a third index table, the third index table includes all the different characters in each document and the position of the characters;

[0068] Writing the first index table, the second index table, and the third index table into the index file for preservation;

[0069] 2) Count the number of occurrences of sentences with a fixed sentence length:

[0070] Read the third index table;

[0071] Because the period, question mark and exc...

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...
