Abstract

The invention provides a classified corpus establishing method and system and a server provided with the system. The establishing method comprises the steps of acquiring target data to be classified and acquiring category description data according to actual needs, selecting a text similarity calculating method corresponding to maximum accuracy, classifying the target data to be classified as a category corresponding to maximum similarity, filling the target data with first classification matching degree within a first similarity range in a preset primary corpus, classifying the rest of the target data to be classified with a selected and well trained classifier, filling the target data with second classification matching degree within a second similarity range in the preset primary corpus, and determining the preset primary corpus as a final corpus when the filled preset primary corpus can not be enlarged any more. In this way, corpus establishment cost is reduced, manual intervene degree is reduced, and corpus establishment time is shortened.

Description

technical field

[0001] The invention belongs to the technical field of natural language processing, and relates to a construction method and system, in particular to a classification corpus construction method, system and a server with the system. Background technique

[0002] In recent years, network technology has developed rapidly, and Internet data has become the main source of information for people due to its advantages such as rapid update, wide range, and easy access. According to statistics, the vast majority of network data exists in the form of text. How to use natural language processing technology to classify these text information, so that users can find useful information more accurately and quickly, has become an important issue in the field of artificial intelligence. an important research question. Faced with this demand, a number of technologies with great practical value have been born, such as information retrieval, data mining, and public opinion monit...
