Boosting Collective Entity Linking via Type-Guided Semantic Embedding

摘要

Entity Linking (EL) is the task of mapping mentions in natural-language text to their corresponding entities in a knowledge base (KB). Type modeling for mention and entity could be beneficial for entity linking. In this paper, we propose a type-guided semantic embedding approach to boost collective entity linking. We use Bidirectional Long Short-Term Memory (BiLSTM) and dynamic convolutional neural network (DCNN) to model the mention and the entity respectively. Then, we build a graph with the semantic relatedness of mentions and entities for the collective entity linking. Finally, we evaluate our approach by comparing the state-of-the-art entity linking approaches over a wide range of very different data sets, such as TAC-KBP from 2009 to 2013, AIDA, DBPediaSpotlight, N3-Reuters-128, and N3-RSS-500. Besides, we also evaluate our approach with a Chinese Corpora. The experiments reveal that the modeling for entity type can be very beneficial to the entity linking.
