Overview of the Cancer Genetics and Pathway Curation tasks of BioNLP Shared Task 2013.
BMC bioinformatics
Jul 13, 2015
BACKGROUND: Since their introduction in 2009, the BioNLP Shared Task events have been instrumental in advancing the development of methods and resources for the automatic extraction of information from the biomedical literature. In this paper, we pre...
Adaptable, high recall, event extraction system with minimal configuration.
BMC bioinformatics
Jul 13, 2015
BACKGROUND: Biomedical event extraction has been a major focus of biomedical natural language processing (BioNLP) research since the first BioNLP shared task was held in 2009. Accordingly, a large number of event extraction systems have been develope...
The contribution of co-reference resolution to supervised relation detection between bacteria and biotopes entities.
BMC bioinformatics
Jul 13, 2015
BACKGROUND: The acquisition of knowledge about relations between bacteria and their locations (habitats and geographical locations) in short texts about bacteria, as defined in the BioNLP-ST 2013 Bacteria Biotope task, depends on the detection of co-...
Prediction of hydrogen and carbon chemical shifts from RNA using database mining and support vector regression.
Journal of biomolecular NMR
Jul 4, 2015
The Biological Magnetic Resonance Data Bank (BMRB) contains NMR chemical shift depositions for over 200 RNAs and RNA-containing complexes. We have analyzed the (1)H NMR and (13)C chemical shifts reported for non-exchangeable protons of 187 of these R...
An Approach for Learning Expressive Ontologies in Medical Domain.
Journal of medical systems
Jun 16, 2015
The access to medical information (journals, blogs, web-pages, dictionaries, and texts) has been increased due to availability of many digital media. In particular, finding an appropriate structure that represents the information contained in texts i...
Detection of sentence boundaries and abbreviations in clinical narratives.
BMC medical informatics and decision making
Jun 15, 2015
BACKGROUND: In Western languages the period character is highly ambiguous, due to its double role as sentence delimiter and abbreviation marker. This is particularly relevant in clinical free-texts characterized by numerous anomalies in spelling, pun...
Fast Distributed Dynamics of Semantic Networks via Social Media.
Computational intelligence and neuroscience
May 17, 2015
We investigate the dynamics of semantic organization using social media, a collective expression of human thought. We propose a novel, time-dependent semantic similarity measure (TSS), based on the social network Twitter. We show that TSS is consiste...
KnowLife: a versatile approach for constructing a large knowledge graph for biomedical sciences.
BMC bioinformatics
May 14, 2015
BACKGROUND: Biomedical knowledge bases (KB's) have become important assets in life sciences. Prior work on KB construction has three major limitations. First, most biomedical KBs are manually built and curated, and cannot keep up with the rate at whi...
Exploring relation types for literature-based discovery.
Journal of the American Medical Informatics Association : JAMIA
May 13, 2015
OBJECTIVE: Literature-based discovery (LBD) aims to identify "hidden knowledge" in the medical literature by: (1) analyzing documents to identify pairs of explicitly related concepts (terms), then (2) hypothesizing novel relations between pairs of un...
Measuring information transfer in a soft robotic arm.
Bioinspiration & biomimetics
May 13, 2015
Soft robots can exhibit diverse behaviors with simple types of actuation by partially outsourcing control to the morphological and material properties of their soft bodies, which is made possible by the tight coupling between control, body, and envir...
