Biomedical question answering: A survey
OBJECTIVES In this survey, we reviewed the current state of the art in biomedical QA (Question Answering), within a broader framework of semantic knowledge-based QA approaches, and projected directions for the future research development in this critical area of intersection between Artificial Intelligence, Information Retrieval, and Biomedical Informatics. MATERIALS AND METHODS We devised a ...
متن کاملNeural Domain Adaptation for Biomedical Question Answering
Factoid question answering (QA) has recently benefited from the development of deep learning (DL) systems. Neural network models outperform traditional approaches in domains where large datasets exist, such as SQuAD (≈ 100, 000 questions) for Wikipedia articles. However, these systems have not yet been applied to QA in more specific domains, such as biomedicine, because datasets are generally t...
متن کاملExternal Knowledge Sources for Question Answering
MIT CSAIL’s entries for the TREC Question Answering track (Voorhees, 2005) focused on incorporating external general-knowledge sources into the question answering process. We also explored the effect of document retrieval on factoid question answering, in cooperation with a community focus on document retrieval. For the new relationship task, we present a new passage-retrieval based algorithm e...
متن کاملQuestion Answering Summarization of Multiple Biomedical Documents
In this paper we introduce a system that automatically summarizes multiple biomedical documents relevant to a question. The system extracts biomedical and general concepts by utilizing concept-level knowledge from domain-specific and domain-independent sources. Semantic role labeling, semantic subgraph-based sentence selection and automatic post-editing are involved in the process of finding th...
متن کاملThe OHSU Biomedical Question Answering System Framework
The Oregon Health & Science University submission to the TREC 2007 Genomics Track approached the entity list question answering task using a modular object oriented system framework. A system object coordinates a collection of processing objects into a pipe that constructs a set of queries, retrieves passage, and then processes those passages into a final output answer set. Using the framework ...
