A Novel Similarity Calculation Method Based on Chinese Sentence Keyword Weight

Abstract

Question Answering system (QA), is a kind of new information retrieval system which can be queried with natural language and return knowledge directly.By improving the traditional Chinese sentence similarity model, this paper proposes a Chinese sentence similarity calculation method based on keywords weight.Its key question is that questions asked by user and questions in the Frequently Asked Question (FAQ) carry on similarity calculation, discover the closest question in the FAQ and return the question answer stored in advance. It can also automatically update and maintain FAQ.The experiment indicates that precision of question match can be improved compared with traditional sentence similarity model.

Application and analysis of text similarity in text clustering in the Chinese context

“…Before clustering, it needs to use the text similarity calculation method to establish a similarity matrix, and then use the appropriate clustering algorithm to cluster the clusters. Therefore, a good similarity calculation method can greatly improve the efficiency of clustering [8].…”
