Latest Patents

Bifan Wei holds a patent titled "Method and device for constructing legal knowledge graph based on joint entity and relation extraction." This patent outlines a comprehensive method for creating a legal knowledge graph. The construction method includes several steps, such as constructing a triple data set, designing a model architecture, and training a model. The model architecture consists of an encoding layer, a head entity extraction layer, and a relation-tail entity extraction layer. The process also involves determining the relationships between sentences in the text, combining triples, and visualizing the graph. Notably, the design of the model framework utilizes a Chinese Bert pre-training model as an encoder. In the entity extraction phase, two BiLSTM binary classifiers are employed to identify the start and end positions of an entity. The head entity is extracted first, followed by the extraction of the tail entity corresponding to the entity relation.
