报告内容简介:

The size of biomedical literature is massive and expands at a fast rate, due to the rapid growth in biomedical research and development. PubMed is an online portal (accessing primarily the MEDLINE database) that include more than 30 million of research articles (abstracts) on life sciences and biomedical topics by the end of January 2020. Biomedical literature provides healthcare practitioners (e.g., physicians, pharmacists) up-to-date biomedical research findings, which can be applied to improve professional practices and healthcare outcomes. Moreover, biomedical literature is core to new knowledge creation and discovery. Because the size of biomedical literature expands rapidly, manual review and inspection of biomedical research articles is very difficult and time-consuming. As a result, the development of some natural language understanding (NLU) techniques that can comprehend or extract important information from this huge collection of literature is essential and desirable.

One important type of information that can be extracted from these articles are biomedical relations discussed in each article. Examples of biomedical relations include drug-disease relations, chemical-protein relations, gene-disease relations, protein interactions, drug-drug interactions, etc. Formally, given a sentence (or a small segment of text) that contains two entities of interest, the task of  relation extraction is to predict whether the sentence describes some relation (out of a predefined set of relation types) between the two entities and, if so, to classify which relation class does the sentence point to. In this talk, I will present our proposed biomedical relation extraction methods that follow the deep-learning-based approach. In addition, in this talk, I will also discuss an important application of biomedical relation extraction, i.e., literature-based drug repurposing.
