Abstract

According to the embodiments of the present disclosure, a method, device, device and medium for determining text relevance are provided. The method of determining text relevance includes identifying a first set of knowledge elements associated with a first text and a second set of knowledge elements associated with a second text from a predefined knowledge base. A knowledge base includes a knowledge representation composed of knowledge elements. The method also includes determining a knowledge element relevancy between the first set of knowledge elements and the second set of knowledge elements, and determining a textual relevancy of the second text to the first text based at least on the knowledge element relevancy. In this way, the determination of textual relevance can be improved by knowledge element-level relevance in the knowledge base.

Description

technical field [0001] Embodiments of the present disclosure mainly relate to the field of computers, and more particularly, to methods, devices, devices and computer-readable storage media for determining text relevance. Background technique [0002] The relevance of the text is also called the matching degree of the text. In many applications, it is necessary to determine the degree of relevance between different texts. A typical scenario is a search application. Usually, when performing a search, it is necessary to determine the correlation between the text in each document and the text in the search query, and determine the ranking of each document in the returned query results based on the correlation, that is, realize the correlation ranking. The determination of text relevance is based on the understanding of the text, which is not only related to the semantic similarity of two texts, but also related to the matching degree between the texts. Although a lot of rese...
