ABSTRACT
Relation classification is an important research arena in the field of natural language processing (NLP).In this paper, we present SDP-LSTM, a novel neural network to classify relation two entities sentence.Our architecture leverages shortest dependency path (SDP) between entities; multichannel recurrent networks, with long short term memory (LSTM) units, pick up heterogeneous information along SDP.Our proposed model has several distinct features: (1) The paths retain most relevant (to classification), while eliminating irrelevant words sentence.(2) LSTM networks allow effective integration from sources over paths.(3) A customized dropout strategy regularizes alleviate overfitting.We test our on SemEval 2010 task, and achieve F 1 -score 83.7%, higher than competing methods literature.
