摘要： The present disclosure provides a method, a device, an equipment and a storage medium for mining a topic concept. The method includes: acquiring a plurality of candidate topic concepts based on a query; performing word segmentation on the plurality of candidate topic concepts and performing part-of-speech tagging on words obtained after performing the word segmentation, to obtain a part-of-speech sequence of each of the plurality of candidate topic concepts; and filtering the plurality of candidate topic concepts based on the part-of-speech sequence, to filter out a topic concept corresponding to a target part-of-speech sequence among the plurality of candidate topic concepts, in which a proportion of accurate topic concepts in the target part-of-speech sequence is lower than or equal to a first preset threshold, or a proportion of inaccurate topic concepts in the target part-of-speech sequence is higher than or equal to a second preset threshold. The present disclosure can reduce the labor cost required for mining the topic concept.

摘要： Embodiments of the present disclosure relate to a theme classification method based on multimodality, a device and a storage medium, more particularly to a field of a knowledge map. The method includes obtaining text information and non-text information of an object to be classified. The non-text information includes at least one of visual information and audio information. The method also includes determining an entity set of the text information based on a pre-established knowledge base, and then extracting a text feature of the object based on the text information and the entity set. The method also includes determining a theme classification of the object based on the text feature and a non-text feature of the object.

摘要： The present disclosure provides a text processing method and device based on ambiguous entity words. The method includes: obtaining (101) a context of a text to be disambiguated and at least two candidate entities represented by the text to be disambiguated; generating (102) a semantic vector of the context based on a trained word vector model; generating (103) a first entity vector of each of the at least two candidate entities based on a trained unsupervised neural network model; determining (104) a similarity between the context and each candidate entity; and determining (105) a target entity represented by the text to be disambiguated in the context. By the present disclosure, entity information of the text to be disambiguated is completely depicted, and accuracy disambiguation for the text to be disambiguated is improved.

摘要： A method and an apparatus for outputting information are provided according to embodiments of the disclosure. A specific embodiment of the method includes: recognizing a target video, to recognize at least one entity and obtain a confidence degree of each entity, the entity including a main entity and related entities; matching the at least one entity with a pre-stored knowledge base to determine at least one candidate entity; obtaining at least one main entity by expanding the related entities of the at least one candidate entity based on the knowledge base, and obtaining a confidence degree of the obtained main entity; and calculating a confidence level of the obtained main entity based on the confidence degree of each of the related entities of the at least one candidate entity and the confidence degree of the obtained main entity, and outputting the confidence level of the obtained main entity. This embodiment integrates single-modal entity annotation results, and performs multi-modal fusion, to break through the bottleneck of the single-modal entity annotation effects, thereby achieving expansion based on knowledge base, and achieving inference and expansion of fine-grained contents on the existing entity annotation results based on the knowledge base.
