Abstract

The invention discloses a lexicon updating method and device and electronic equipment. The method comprises the steps that audit new corpora are acquired, and the audit new corpora comprise audit basic words and electric power data statements; labeling the audit new corpus to obtain basic sample data; a new word retrieval model is adopted to identify new words in the basic sample data, the new word retrieval model is obtained on the basis of training of multiple sets of data, and each set of data in the multiple sets of data comprises lexicon words and new word prediction probabilities; and updating the audit data lexicon based on the new words. According to the method and the device, the technical problems of unbalanced data quality and incomplete data of a term database due to the fact that professional terms are easy to miss when corpora are extracted in related technologies are solved.

Description

technical field [0001] The present invention relates to the technical field of power data processing, in particular, to a method and device for updating a lexicon, and electronic equipment. Background technique [0002] In the field of electric power, unregistered words are a big problem when performing word analysis on unprocessed original corpus. Unregistered words refer to words that are not included in the electric power word segmentation vocabulary but must be segmented, including All kinds of proper nouns (names of people, places, companies, etc.), abbreviations, new vocabulary, etc. Moreover, most of the unregistered words are technical terms in the field of electric power, so term discovery is an urgent problem that needs to be solved. The discovery of terms directly affects the quality of the corpus. In the process of term discovery, the main task is to complete term extraction, that is, from the Terms are extracted from the processed corpus to ensure the comprehen...
