| Abstract: | Purpose/significance] Aiming at the problem of semantic extension in automatic question answering system, this paper proposes a semantic extension technology based on word vector, and designs and implements a library intelligent consulting system.Method/process] Using word2vec word vector semantic extension technology, Chinese word segmentation and co-occurrence matching technology, an intelligent Q & A engine was designed. Combined with the concept of collaborative office, the library intelligent consulting system was realized, and the operation data of the system was statistically analyzed.Result/conclusion] The system meets the design requirements well in terms of working hours, consultation effect and back-stage management, and provides reference for the construction of library intelligent consultation system. |
