Abstract

The invention discloses a method and a system for linking entities. The method includes acquiring to-be-linked entities from given texts; acquiring entity names and abbreviation word banks from preset knowledge bases and establishing synonym banks of the entity names on the basis of the preset knowledge bases; carrying out searching in the synonym banks by the aid of entity keywords; linking the entity keywords for searching and the entity names in the preset knowledge bases if a certain entry matched with the synonym banks is found by means of searching; generating candidate entities if the certain entry is not found by means of matching and carrying out disambiguation linking in context similarity evaluation modes. The synonym banks contain the entity names acquired from the preset knowledge bases and information data related to the entity names. The entity keywords are acquired by means of word segmentation and are used as search terms. The entity names in the knowledge bases correspond to the entry. The method and the system in an embodiment of the invention have the advantage that the entity linking accuracy can be improved.

Description

technical field [0001] The invention relates to the field of unstructured text processing, in particular to a method and system for linking entities. Background technique [0002] With the widespread use of computers and the rapid development of the Internet, the Internet has become a very important channel for people to obtain information.
