Domain adaptation for semantic role labeling of clinical text.

Journal of the American Medical Informatics Association : JAMIA Jun 10, 2015
OBJECTIVE: Semantic role labeling (SRL), which extracts a shallow semantic relation representation from different surface textual forms of free text sentences, is important for understanding natural language. Few studies in SRL have been conducted in...

A Model of Emergent Category-specific Activation in the Posterior Fusiform Gyrus of Sighted and Congenitally Blind Populations.

Journal of cognitive neuroscience Jun 4, 2015
Theories about the neural bases of semantic knowledge tend between two poles, one proposing that distinct brain regions are innately dedicated to different conceptual domains and the other suggesting that all concepts are encoded within a single netw...

Identifying synonymy between relational phrases using word embeddings.

Journal of biomedical informatics May 22, 2015
Many text mining applications in the biomedical domain benefit from automatic clustering of relational phrases into synonymous groups, since it alleviates the problem of spurious mismatches caused by the diversity of natural language expressions. Mos...

A formal concept analysis and semantic query expansion cooperation to refine health outcomes of interest.

BMC medical informatics and decision making May 20, 2015
BACKGROUND: Electronic Health Records (EHRs) are frequently used by clinicians and researchers to search for, extract, and analyze groups of patients by defining Health Outcome of Interests (HOI). The definition of an HOI is generally considered a co...

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...
