Abstract

The invention discloses a text vector representation method and a text vector representation device. The text vector representation method includes the steps of acquiring a test text; subjecting the test text to characterization so as to obtain a target text represented by multiple text characteristics; processing the target text by a prestored characteristic subject relation matrix so as to obtain subject distribution of the target text, wherein the subject distribution includes a target subject of the target text and a proportion corresponding to the target subject; extending the text characteristics describing the target subject by a prestored characteristic embedded vector set to obtain a target subject characteristic set, and acquiring a vector representing the target subject according to the target subject characteristic set; subjecting the subject distribution and the vector representing the target subject to computation so as to obtain a vector representing the test text. By the text vector representation method, the problem that text vector representation methods in related technologies are weak in ability to present semantic information included in the text.

Description

technical field [0001] The present application relates to the field of natural language processing, in particular, to a text vector representation method and device. Background technique [0002] Text vector representation is the process of representing unstructured text into mathematical vectors through a series of calculations, which is the basis and premise of many tasks in the field of natural language processing. In tasks such as text classification, text clustering, and similarity calculation, it is necessary to perform vectorized transformation on the text in advance, and then use the vectorized text to replace the original text for mathematical operations and statistics. It can be seen that the quality of the text vector representation will directly affect the subsequent analysis results. At present, the general method of text vector representation is to use the Vector Space Model (Vector Space Model, referred to as VSM) to represent the text as vectors under severa...
