Abstract

The invention discloses a phrase extraction method and a device, electronic equipment and a storage medium, and relates to the technical field of big data. The method comprises the steps of: segmenting a corpus text to obtain short sentences; extracting candidate phrases according to dependency relationships and part-of-speech among the words in the short sentences; and if the phrases meet the preset conditions, storing the candidate phrases into a phrase matching corpus. Therefore, the phrase matching mode conforming to the part-of-speech combination can be determined according to the dependency relationship and the part-of-speech among the words in the sentence, and the phrase extraction efficiency and accuracy of the corpus text are improved.

Description

technical field [0001] The present application relates to intelligent search technology in the field of big data technology, and in particular to a phrase extraction method, device, electronic equipment and storage medium. Background technique [0002] With the development of data processing technology, the function of intelligent search is becoming more and more powerful. In addition to searching for relevant content based on keywords, users can also search for phrase matching results by entering a phrase with interrogative words. [0003] At present, the phrase collocation corpus is generally pre-built by manual annotation or co-occurrence analysis. When the user enters a phrase with question words, the search engine searches all the phrases that meet the requirements from the phrase collocation corpus. [0004] However, the manual labeling method requires a lot of manpower for corpus labeling, and the co-occurrence analysis method cannot analyze the collocation of words ...
