Human-computer interaction intelligent question answering method based on cloud platform

Abstract

The invention discloses a human-computer interaction intelligent question answering method based on a cloud platform, which comprises the following steps: acquiring voice information input by a user;performing voice-to-text conversion on the voice information to obtain text information; performing word segmentation processing on the text information to obtain keyword extraction results; using a machine learning algorithm to classify the obtained keyword extraction results so as to obtain classification results; using a natural language processing algorithm to perform keyword expansion on verbs and nouns in the keyword extraction results and taking out a result with the largest similarity from the results of the keyword expansion in each of the verbs and nous, wherein all the results forma keyword expansion sequence; and performing fuzzy matching in a local database according to the classification results and the keyword expandable sequence. The human-computer interaction intelligentquestion answering method based on the cloud platform in the invention can solve the technical problem of low interaction accuracy caused by inaccurate word segmentation, inaccurate keyword expansion,and inaccurate extraction of answers in the existing human-computer interaction question answering system.

Description

technical field [0001] The invention belongs to the technical field of artificial intelligence, and more specifically, relates to a method and system for human-computer interaction intelligent question answering based on a cloud platform. Background technique [0002] Human-computer interaction question answering system has been developed with artificial intelligence in daily life. For example, the well-known chat robot is a practical application product that has only appeared in recent years, and it has become a new hot spot in smart phone application development. [0003] Existing human-computer interactive question answering systems include interactive question answering systems based on local libraries, community question answering systems, and chat robots. The interactive question answering system based on the local library is that the user enters a question, then searches in the local library, and gives the final answer; the community question answering system is A use...
