Embodiment Construction

[0039] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0040] The semantic tree-based full-text search engine service provided by the present invention includes: document import, semantic tree construction, relationship between feature semantics and documents, storage of document information, and semantic-based search function. Simply put, it includes two parts: the establishment of the semantic tree and the search of the statement.

[0041] figure 1 Describe the process of building a semantic tree. Specifically include the following:

[0042] import of documents;

[0043] Determine the information fields that need to be indexed in the document results;

[0044] Determine the text encoding range that needs to be indexed;

[0045] Determine the separator of the text;

[0046] Divide the document into sentences;

[0047] Encode the feature information of the sentence;

[0048] Store the featu...

Abstract

The invention mainly relates to the field of full-text search, discloses a built semantic tree and provides a semantic tree based indexing method and system. According to the method, a statement is subjected to incremental hash-coding processing according to a sequence of characters in the statement, specific semantic information coding is formed, pre-semantic feature information, characters and semantic features are stored, and the semantic tree is built; semantic based indexing basis is established according to the semantic tree, a semantic tree and document association table and document storage, and a semantic tree based full-text search engine is provided. The semantic tree based indexing method and system have the advantages of no dependence on word segmentation service, small storage space, high query speed and the like, and are suitable for full-text index of character information and semantic comprehension and processing based on the semantic tree.

Description

technical field [0001] The invention mainly relates to the field of full-text retrieval, proposes a semantic tree construction, and provides an indexing method and system based on the semantic tree. Background technique [0002] Full-text retrieval is mainly divided into two parts: article indexing and search. The index of the article mainly refers to the index of keywords. To put it simply, the indexing program scans the article to create an index for each word, and records the number and position of the word in the article. When querying, the retrieval program searches according to the pre-established index and compares the results of the search Feedback to the user's retrieval method. [0003] The full-text retrieval system is a software system established according to the full-text retrieval theory and used to provide full-text retrieval services. Generally speaking, full-text search needs to have the basic functions of indexing and providing query. In terms of funct...
