Abstract

The invention relates to the technical field of artificial intelligence, and discloses an information recognition method and device based on semantic enhancement, a medium and equipment, and the method comprises the steps: obtaining to-be-recognized text information and keywords; obtaining similar words of the keyword in a pre-trained word vector library; adopting a preset context coding model to code the similar words to obtain hidden vectors of the similar words, calculating word vector weights of the similar words according to the hidden vectors, and obtaining semantic enhancement information of the keywords through calculation; calculating the information weights of semantic enhancement information and hidden vectors relative to keyword semantic understanding through a preset gating model, calculating semantic feature parameters of keywords according to the information weights, calculating semantic prediction sequence tags corresponding to the semantic feature parameters, and performing semantic recognition on text information to be recognized. Therefore, semantic enhancement of the keywords is realized, the weights of the context environment and the semantic enhancement information are balanced, and the text information to be identified is accurately identified.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence, in particular to an information recognition method, device, medium and equipment based on semantic enhancement. Background technique [0002] At present, Weibo occupies a vital part in the field of domestic social media. With the increasing popularity of Weibo, user data is also increasing. The text in these user data is usually short and informal, that is, users want to The information expressed is hidden in unstructured posts. Since these user data are unstructured data, there are certain obstacles in extracting information from these user data. How to effectively understand these texts is still a challenging task. . [0003] Named Entity Recognition (NER) is a task of discovering information entities and identifying their corresponding categories. It is widely used in question answering, topic modeling, information retrieval and other fields. It is an important part ...
