Abstract

The invention provides a recognition method of a named entity and relates to the technical field of language recognition. The recognition method of the named entity adopts the mode of composite recognition, conducts word segmentation processing on each sentence firstly, (obtains the word units to be recognized) on the basis of the result of the word segmentation, confirms the word class, the language structure and the occurrence situation of the word unit to be recognized in various reference named dictionaries, and accurately confirm the recognition results of the name entity according to the occurrence situation (which reference named dictionary the word units to be recognized occurs in) of different word units in the reference named dictionaries and the word class and the language structure. Since each word unit to be recognized is matched with a corresponding reference named dictionary, more accurate recognition of the named entity can be conducted on the word units to be recognized according to the reference named dictionaries.

Description

technical field [0001] The invention relates to the field of language recognition, in particular to a method for recognizing named entities. Background technique [0002] Named entity recognition is information extraction, question answering system, syntax analysis, machine translation, oriented to Semantic Web (Semantic Web, which is a global information network alliance Tim Berners-Lee (Tim Berners-Lee) proposed in 1998 A concept, its core is: by adding semantic "metadata (Meta data)" that can be understood by computers to documents on the global information network (such as: an application HTML under the standard general markup language), so that the entire The Internet has become a general information exchange medium), important basic tools in application fields such as metadata labeling, occupy an important position in the process of natural language processing technology becoming practical. Generally speaking, the task of named entity recognition is to identify three ...
