Abstract

The invention discloses an intelligent robot chat system and method based on similar-sentence searching. The system includes a receiving unit used for receiving a sentence input by a user, a similar-sentence calculation unit used for calculating a sentence which is in sentences included in a question and answer knowledge library and is closest to the sentence input by the user, an output unit usedfor outputting a corresponding answer in the question and answer knowledge library, and a question and answer knowledge library unit used for storing dialogues in various situations. According to thesystem, on the one hand, a method of information retrieval is adopted, an inverted index is established in the question and answer knowledge library, to-be-found vocabulary can be quickly located ininverted indexing, and index space is saved at the same time; and on the other hand, weight calculation and sentence word order distance comparison are carried out according to different part-of-speech of vocabulary, cases where words used in sentences are similar but meanings are different can be distinguished, thus the more accurate similar sentence is obtained, a more accurate searching resultis provided, and interactive experience of the user is enhanced.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence, in particular to an intelligent robot chatting system and method based on similar sentence search. Background technique [0002] With the development of information technology, intelligent robots have gradually become an important auxiliary tool in people's lives. People hope to have more convenient ways to obtain information and a more humanized human-computer interaction experience. However, the way of human-computer interaction has not changed much at present, especially the method for users to obtain information is not effective enough. It is of great significance to promote the development of human-computer interaction through the study of chat robot related technologies. [0003] At present, in chatbots, user utterances are treated superficially by simply considering the direct matching of a single or several words. Contents of the invention [0004] The object of the pr...
