Learning Entity Representation for Named Entity Disambiguation
Rui Cai, Houfeng Wang, Junhao Zhang · Lecture notes in computer science · 2015
In this paper we present a novel disambiguation model, based on neural networks. Most existing studies focus on designing effective man-made features and complicated similarity measures to obtain better disambiguation performance. Instead, our method learns distributed representation of entity to measure similarity without man-made features. Entity representation consists of context document representation and category representation. Document representation of an entity is learned based on deep neural network (DNN), and is directly optimized for a given similarity measure. Convolutional neural network (CNN) is employed to obtain category representation, and shares deep layers with DNN. Both models are trained jointly using massive documents collected from Baike http://baike.baidu.com/ . Experiment results show that our method achieves a good performance on two datasets without any manually designed features.
