Problems solved by technology

However, these de-duplication techniques are subject to certain degree, and cannot meet the requirement of maintaining good consistency of feature words extracted from multiple texts.
[0004] In addition, the computational complexity of existing feature mapping methods is too high

Abstract

A method, a device, an apparatus, and a storage medium for de-duplication of feature word are disclosed. The method includes: acquiring a set of phrases associated with a current feature word in the set of feature words; calculating a sum of a specified part of a phrase based on an ASCII code corresponding to the phrase one by one to obtain a first set of sum values; the deduplicated feature wordsbeing determined by judging the number of minimum values in the first set of sum values. According to the technical proposal of the embodiment of the present application, by calculating the sum of ASCII codes, the feature words with the same meaning are de-duplicated, thereby reducing the computational complexity of the current feature word de-duplication method, saving computational space, and significantly improving the generalization ability of the current feature words to the text.

Description

technical field [0001] The present application generally relates to but not limited to the technical field of semantic analysis, and specifically relates to a method, device, equipment and storage medium for deduplication of characteristic words. Background technique [0002] In natural language processing technology, the smallest meaningful unit in natural language is a phrase or word. Generally speaking, the significance of extracting a single phrase as a feature word is that it can well summarize the main content of the text and reduce the complexity of text processing. In the prior art, there are many algorithms for extracting feature words based on text, such as word frequency-inverse document frequency (TF-IDF) method, information gain and other algorithms. [0003] With the development of technology, there may be multiple words expressing the same meaning among the feature words extracted from multiple texts, resulting in redundancy of feature words. The current fea...
