Abstract

The invention discloses a method, device and device for identifying a named entity based on a map. The idea of ​​the present invention is to solve the problem of insufficient information and inconsistent form in the input text in a specific scene, making it difficult to recognize some objects with ambiguous meanings in the text. The attribute information of the image attached to the scene and the deep information of the text are introduced to prevent the recognition of certain objects in the text. Auxiliary named entity recognition processing, in particular, the present invention proposes to transform image information at the text level, so that image attributes can be unified with text deep information and basic text information, so that the basic text information, deep information, map attribute information and image information can be unified. When multi-modal comprehensive processing of basic information is performed, on the one hand, it can make up for the problem of insufficient input text information, and on the other hand, it can reduce the spatial heterogeneity of images and texts, so that text and images can fully interact and combine in depth, so that It can greatly improve the recognition efficiency and accuracy of named entities in this scenario.

Description

technical field [0001] The present invention relates to the field of knowledge graphs, in particular to a named entity recognition method, device and equipment based on graphs. Background technique [0002] Named Entity Recognition (NER) is a key technology for information extraction. The main task of named entity recognition is to identify entities with specific meaning in the text, mainly including names of people, places, institutions, and proper nouns. The implementation process Usually, the boundary range of the entity in the input text is determined first, and then the type label of the entity is determined. [0003] At present, for texts with good sentence structure and sufficient context information, based on technologies such as BiLSTM+CRF or Bert+CRF, satisfactory entity recognition results have been achieved. However, due to the characteristics of short text, insufficient context, colloquialism, incorrect spelling, and abbreviation in some specific application fi...
