Protein Name Recognition Based on Dictionary Mining and Heuristics

We propose a novel method that integrates dictionary, heuristics and data mining approaches to efficiently and effectively recognize exact protein names from the literature. According to the protein name dictionary and heuristic rules published in related studies, core tokens of protein names can be efficiently detected. However, exact boundaries of protein names are hard to be identified. By regarding tokens of a protein name as items within a transaction, we apply mining associations to discover significant sequential patterns (SSPs) from the protein name dictionary. Based on SSPs, protein name parts are extended from core tokens to left and right boundaries for correctly recognizing the protein name. Based on Yapex101 corpus, Protein Name Recognition System (PNRS) achieves the F-score (74.49%) better than existing systems and papers.
