- Abstract:
-
Embedding-based feature extraction methods usually ignore path semantics; there is still scope of improvement of relational path-based algorithms, which generally consider single paths. To further boost the performance of knowledge-based inferences, a self-defined convolutional neural network framework was employed to encode multiple paths generated by random walks into low-dimensional representations that are merged to form a single vector of hidden states with long-short term memory (LSTM); this is accomplished by combining the attention mechanism-based processes. Semantic information of multiple paths is integrated with various weight distributions used for measuring probability scores of triples comprising candidate relations and entity pairs to determine whether the triples hold or not. Link prediction experiments performed on NELL995 and FB15k-237 demonstrated the capability of the proposed model. Scores of F1 and other indicators also confirmed the advantages of our framework compared with mainstream models. The model was further tested on FC17 and NELL-One.
