Abstract

Relation extraction is an important task in information extraction. While dealing with the question-answer pairs, in addition to the relations among the entities in the texts, the question pattern as the relation connected questions and the answers also needs to be extracted. The combination of the supervised labeling algorithm(conditional random field) and the semi-supervised algorithm based on a feature template(Bootstrapping) has a good performance when extracting relationships between entities. However, the method to find the template in the traditional semi-supervised algorithm is hard to move to the extraction of the question pattern. Therefore, this paper proposed model based on the combination of sentence2vec technology and semi-supervised algorithm, which introduced the sentence vector to calculate the text similarity and selected the sentence template. It used random sampling validation to verify the final result. The experimental results show that the method has higher precision and recall values than the traditional semi-supervised algorithm.
