Problems solved by technology

Traditional semantic lexicon compilation is inefficient due to the limited number of personnel performing data collection and processing, coupled with the manual nature of data collection and processing
In today's information explosion, natural language processing systems need to process massive corpus data, and such inefficient semantic dictionary compilation efficiency is obviously difficult to meet the needs of information processing and processing

Abstract

The embodiment of the invention discloses a semantic dictionary construction method and device. The semantic dictionary construction method includes: extracting sentences with the same or similar semantics from the user's web log; according to the semantics of words in the sentences with the same or similar semantics, the Words are aligned to obtain alternative words with the same or similar semantics; according to the context information of the alternative words in the sentence with the same or similar semantics, the alternative words are clustered to obtain Get words with the same semantic meaning and add the words with the same semantic meaning to the semantic dictionary. The semantic dictionary construction method and device provided by the embodiments of the present invention efficiently construct a semantic dictionary including synonym data by mining users' web logs.

Description

technical field [0001] Embodiments of the present invention relate to network data processing technology, and in particular to a method and device for constructing a semantic dictionary. Background technique [0002] According to the current engineering practice of natural language processing, building a semantic dictionary with rich corpus and reliable data plays a fundamental role in improving the processing efficiency and accuracy of natural language processing systems. However, traditional semantic dictionaries mostly rely on manual data collection and processing. Moreover, because the semantic dictionary itself has high professional requirements for data, the personnel who need to collect and process data have high professional background knowledge and profound language skills. Therefore, the number of people who can meet the above requirements and participate in the compilation of semantic dictionaries is generally small. Due to the limited number of personnel perfor...
