Quick retrieval method and system

Abstract

The invention discloses a quick retrieval method and system. The method comprises the steps of S1, performing preprocessing and text quantification on a to-be-retrieved user questioning text; s2, constructing an n-dimensional space according to a quantization result; s3, randomly selecting n points in the n-dimensional space, and constructing a segmentation hyperplane of the n-dimensional space and a vertical bisector of the segmentation hyperplane based on the n points; s4, repeatedly executing S3 until m points are left in the segmented region; s5, constructing a binary tree, and establishing a binary tree index; s6, performing word segmentation, stop word removal and text quantification processing on the retrieval text; s7, retrieval traversal is carried out according to the binary treestructure until leaf nodes are reached, similar text data of the retrieval text are obtained, the similarity between the retrieval text and each similar text data is calculated, and the similar textdata with the highest similarity are taken; and S8, performing retrieval in the database based on the similar text data with the highest similarity to obtain a final answer of the similar text data with the highest similarity, and taking the final answer as an answer of the retrieval ontology.

Description

Technical field [0001] The present invention belongs to the field of natural language processing information retrieval, and in particular to a quick retrieval method and system. Background technique [0002] With the rapid development of Internet technology, data is an important carrier for information transmission. In the field of human-machine dialogue, for massive data retrieval, traditional methods have higher time complexity, in a scene of some real-time requirements, obviously do not satisfy requirements, so constructing a quick retrieval method is especially important. Inventive content [0003] The present invention provides a new type of fast retrieval method and system for problems and insufficient problems and insufficient prior art. [0004] The present invention solves the above technical problems by the following technical solutions: [0005] The present invention provides a rapid retrieval method, characterized in that it includes the steps of: [0006] S1, prepro...

Problems solved by technology

In the field of human-computer dialogue, for massive data retrieval, the traditional method has high time complexity, and obviously does not meet the requirements in some scenarios with high real-time requirements. Therefore, it is particularly important to construct a fast retrieval method. important
