Abstract: Implementations of the present disclosure relate to methods, devices, and computer program products of extracting a feature for multimedia data that comprises a plurality of medium types. In a method, a first feature is determined for a first medium type in the plurality of medium types by masking a portion in a first medium object with the first medium type. A second feature is determined for a second medium type other than the first medium type in the plurality of medium types. The feature is generated for the multimedia data based on the first and second features. With these implementations, multiple medium types are considered in the feature extraction, and thus the feature may fully reflect various aspects of the multimedia data in an accurate way.

Abstract: The present disclosure relates to a web page classification method, apparatus, storage medium, and electronic device. The method comprises: acquiring feature information of a web page to be classified; respectively predicting, according to each piece of the feature information, a candidate web page category of the web page to be classified; and determining, from all the candidate web page categories, a target web page category to which the web page to be classified belongs. The candidate web page category of the web page to be classified is predicted by using various feature information of the web page to be classified, and the target web page category of the web page to be classified is further determined from the candidate web page categories, thereby improving the accuracy of web page classification.

Abstract: The present disclosure relates to a method and apparatus for knowledge graph construction, storage medium and electronic device. The method for knowledge graph construction, comprises: identifying an entity concept from a title text of a target web page and at least one entity corresponding to the entity concept from a body text of the target web page; constructing a syntax parse tree of the title text based on syntax parse rules of a language to which the title text belongs, and determining, from the syntax parse tree, a modifier for modifying the entity concept; and generating a knowledge graph based on the entity concept, the modifier, and the at least one entity. Through the solution of the present disclosure, knowledge graphs with high accuracy and high recall rates are constructed without structured processing on target web pages.
