Relying on the massive high-quality data of the whole network and deep neural network technology, the similarity between two words is calculated through word vectorization to meet the business scenario requirements of high-precision requirements
This technology is often used to calculate the semantic similarity of two given words. Based on the distribution assumption in natural language, that is, the more frequently the words appear together, the higher the similarity is
Leading technology application
Word sense similarity is an important basic technology in natural language processing, and is one of the foundations of common technologies such as proper name mining, query rewriting, part of speech tagging, etc
Application scenarios
Proper name mining
Query rewriting
Proper name mining
Find related words of person name, place name, organization name, etc. through semantic correlation calculation between words, expand the dictionary of proper nouns, and better assist application
