Combining Multiple Layers of Syntactic Information for Protein-Protein Interaction Extraction
نویسندگان
چکیده
Protein-protein interaction extraction is a challenging information extraction task in the BioNLP field. Several kernels focusing on a part of syntactic information have been proposed for the task. In this paper, we propose a method to combine multiple layers of syntactic information by using a combination of multiple kernels based on several different parsers. We evaluated the method using support vector machine and achieved an F-score of 62.0% on the AIMed corpus. Further, we analyzed the performance with or without including self-interaction pairs, and found that there is a danger of confusing classifiers and decreasing the performance when treating self-interaction pairs together with real pairs.

Integrating Semantic Information into Multiple Kernels for Protein-Protein Interaction Extraction from Biomedical Literatures
Protein-Protein Interaction (PPI) extraction is an important task in the biomedical information extraction. Presently, many machine learning methods for PPI extraction have achieved promising results. However, the performance is still not satisfactory. One reason is that the semantic resources were basically ignored. In this paper, we propose a multiple-kernel learning-based approach to extract...
