Abstract

Embodiments of the present application provide a data clustering method and apparatus for constructing a knowledge base, wherein the method includes obtaining a local density and a mutually exclusivedistance of each data point of a data set, each data point corresponding to a problem; determining at least one data point as a clustering center according to the local density and the mutual exclusion distance; generating clusters for each clustering center, wherein the clusters comprise all data points in a preset clustering area around the clustering center; according to the distance between the remaining data points outside the cluster and the cluster center, adding the remaining data points to the cluster. The present application is based on the idea of clustering of local density maxima,when the method of the present application generates a knowledge base for an intelligent question answering system, the quality of the question clustering can be improved, so that the intelligent question answering system provides a more reliable intelligent question answering service for a user.

Description

technical field [0001] The present application relates to the technical field of natural language processing, in particular to a data clustering method and device for building a knowledge base. Background technique [0002] The intelligent question answering system can receive user questions described in natural language and match the answers to the questions by searching the knowledge base. Compared with search engines, intelligent question answering systems can better understand the real intention of users to ask questions, and at the same time more effectively meet users' information needs. [0003] The generation of answers to user's questions by the intelligent question answering system depends on the knowledge base and the retrieval algorithm corresponding to the knowledge base. Since the knowledge base is usually obtained by collecting and sorting out questions in some application fields by those skilled in the art, the scale is limited. Therefore, in the intelligent...
