Text information screening method, device and equipment

Abstract

The embodiment of the invention discloses a text information screening method, device and equipment, and the method comprises the steps: obtaining a related question text corresponding to a target question text, and enabling an answer text of the related question text to form a candidate answer text; performing word segmentation on the candidate answer text to obtain a word segmentation result, and calculating a word segmentation transition probability according to an association relationship among segmented words in the word segmentation result; and calculating a probability value of each candidate answer text according to the segmented words included in each candidate answer text and the segmented word transition probability, and determining the candidate answer text with the maximum probability value as a target answer text of the target question text, wherein the probability value of each candidate answer text calculated on the basis of the word segmentation transition probabilityaccurately represents the possibility that each candidate answer text can accurately reply to the target question, so that the accurate target answer can be accurately screened out subsequently on thebasis of the probability value, and the screening accuracy of the target answer is improved.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a text information screening method, device and equipment. Background technique [0002] Question answering system is a commonly used information retrieval system. The question answering system can use natural language to answer questions raised by users in natural language, and the answering process is specifically: after the user asks a question, the question answering system can use the question and answer pairs recorded in the question answer database to retrieve the answer corresponding to the question, so as to use The retrieved answers answer user questions. Wherein, a question-answer pair refers to a question and an answer that have a corresponding relationship. [0003] However, because the question-answer database includes a large number of question-answer pairs, the question-answer system cannot accurately retrieve the exact answers correspondin...

Problems solved by technology

[0003] However, because the question-answer database includes a large number of question-answer pairs, the question-answer system cannot accurately retrieve the exact answers corresponding to the user's questions from these large number of question-answer pairs, which reduces the accuracy of the answers answered by the question-answer system for the user's questions.
