METHOD AND APPARATUS FOR MINING ENTITY FOCUS IN TEXT

摘要

The present disclosure relates to the field of knowledge graph. Embodiments of the present disclosure disclose a method and apparatus for mining an entity focus in a text. The method includes: performing word and phrase feature extraction on an input text; inputting an extracted word and phrase feature into a text coding network for coding, to obtain a coding sequence of the input text; processing the coding sequence of the input text using a core entity labeling network to predict a position of a core entity in the input text; extracting a subsequence corresponding to the core entity in the input text from the coding sequence of the input text, based on the position of the core entity in the input text; and predicting a position of a focus corresponding to the core entity in the input text using a focus labeling network, based on the coding sequence of the input text and the subsequence corresponding to the core entity in the input text. This method realizes a precise extraction of the entity focus in a text.
