Problems solved by technology

[0004] Under normal circumstances, the text to be tested is short, resulting in a small TF of each word. For example, the TF of the word "report the loss" in I want to report the loss is 1, so that using the TF-IDF technology, the obtained word inaccurate weights, resulting in inaccurate text hits from the corpus with word-based weights

Abstract

The embodiment of the invention provides a keyword weight obtaining method and device, an electronic device and a readable storage medium. Due to the fact that floating factors of service operating pages corresponding to keywords are considered, equivalently the probability is considered that texts corresponding to the service operating pages are selected, the weights of the keywords can be obtained, and the important degrees of the keywords to files included in a corpus can be accessed. The weights of the keywords are greater, the keywords are more important for the files included in the corpus. Based on the weight of each keyword in a keyword set, the greater the probability is that the file obtained form the corpus are texts which a user is intent to check, and the files are more accurate.

Description

technical field [0001] The present invention relates to the technical field of weighting, and more specifically, relates to a keyword weight acquisition method, device, electronic equipment and readable storage medium. Background technique [0002] TF-IDF (term frequency–inverse document frequency) is a commonly used weighting technique for information retrieval and data mining, which uses the weight of words to evaluate the importance of a word to the documents contained in the corpus. TF (Term Frequency) refers to the word frequency in the text to be tested, and IDF (Inverse Document Frequency) refers to the reciprocal of the number of documents containing the word in the corpus, that is, the inverse text frequency index. Based on TF and IDF, the weight of words in the text to be tested can be used to hit one or more texts in the corpus. [0003] Intelligent question answering is to use TF-IDF technology to determine the text that the user may need from the corpus based o...
