The invention discloses a text core word identification method and device. The method comprises the steps of training to obtain a condition random field (CRF) model according to a primary sample text,primary preferential core words of the primary sample text and entity features of the primary preferential core words; using the CRF model and at least one keyword extracting algorithm to select secondary preferential core words of a secondary sample text respectively for keywords extracted from the secondary sample text; according to the secondary sample text and the secondary preferential corewords, training a deep neural network model according to the secondary sample text and the secondary preferential core words to obtain a text core word identification model; using the text core word identification model to identify core words of a target text. By means of the text core word identification method and device, through optimization of a training sample from multiple layers, the identification accuracy of the text core word identification model is improved, so that the accuracy of the extracted core words is improved.
Description
technical field [0001] The present disclosure generally relates to the field of Internet technology, and specifically relates to a text core word recognition method and device. Background technique [0002] With the development of computer and network technology, the number of digitized files is increasing at an alarming rate. People spend a lot of time and energy reading and searching for documents every day. In order to save time and improve people's work efficiency, various concise representations of original documents (such as abstracts, keywords, core words, etc.) have emerged as the times require. Core words are defined as words that compress important information and core content of the original text. People can use it to quickly understand the general content of the text without reading the full text. In information retrieval, core words are often used by us to find content-related text or pictures and videos carrying text. [0003] For example, through keyword-b...
