Abstract

The invention provides a text information similarity matching method and device on the basis of TF-IDF. The method includes the steps of acquiring text information; performing word segmentation on thetext information to obtain word segments w1, w2, ..., wn-1 and wn; using a CBOW model for calculating word vectors V(w1), V(w2), ..., V(wn-1) and V(wn) of the word segments respectively; using the TF-IDF algorithm for calculating TF-IDF values k1, k2, ..., kn-1 and kn of the word segments respectively; according to products of the word vectors of the word segments and the corresponding TF-IDF values, obtaining a sentence vector V; calculating the cosine similarity between the sentence vector V and sentence vectors of pre-stored statements, and determining the pre-stored statement with the maximum cosine similarity. Through the process above, the pre-stored statement which is the most similar to the text information can be found, the accuracy of problem recognition can be improved in the aspects of robot dialogue, information classification and the like, and therefore the dialogue efficiency or the classification efficiency is improved. A computer device and a storage medium are also provided.

Description

technical field [0001] The present invention relates to the technical field of text information identification. Specifically, the present invention relates to a TF-IDF-based text information similarity matching method and device, a computer device and a storage medium storing computer-readable instructions. Background technique [0002] With the development of intelligence, customer service robots and chat robots are becoming more and more popular. Users can consult customer service robots by inputting text messages, or chat with chat robots. [0003] When the robot recognizes the text information sent by the user, it needs to give feedback based on the text information. Generally speaking, the feedback information can be determined according to the retrieval method or the generation method according to the text information. The generation method is to automatically generate answers based on the model. This method requires a large number of labeled question-answer pairs for...
