چکیده

We approach the BioCreative VI Track 1 task of biological entity identification by focusing on named entity recognition (NER) and linking tagged entities to standard database identifiers. For this task, we apply recent neural NER techniques of combining bi-directional long short term memory (BLSTM) network layers with conditional random fields (CRFs) to the biomedical domain. We then use context words, dictionary lookups, and external biological knowledge bases to match tagged biological entities with corresponding identifiers. Our system predicts cell types and cell lines, cellular components, organisms and species, proteins and genes, small molecules, and tissues and organs. Keywords—named entity recognition; NER; bi-directional LSTM; conditional random fields; CRF; dictionary lookup

Named Entity Recognition in Persian Text using Deep Learning

Named entities recognition is a fundamental task in the field of natural language processing. It is also known as a subset of information extraction. The process of recognizing named entities aims at finding proper nouns in the text and classifying them into predetermined classes such as names of people, organizations, and places. In this paper, we propose a named entity recognizer which benefi...
