Our goal is to extract and display temporal entities in textual documents. The task involves identification of all events in a document followed by identification of important events using a classifier. We present a user with the key events and their associated people, places, and organizations within a document in terms of a timeline and a map. For(More)

ABSTRACT Objective To evaluate state-of-the-art unsupervised methods on the word sense disambiguation (WSD) task in the clinical domain. In particular, to compare graphbased approaches relying on a clinical knowledge base with bottom-up topic-modeling-based approaches.(More)
Lexical ambiguity, the ambiguity arising from a string with multiple meanings, is pervasive in language of all domains. Word sense disambiguation (WSD) and word sense induction (WSI) are the tasks of resolving this ambiguity. Applications in the clinical and biomedical domain focus on the potential disambiguation has for information extraction. Most(More)
Traditional labeling theory usually contends that pathological labels contribute to pathology and benign labels help alleviate it. However, it is likely that the role of pathological labels as the cause of pathology has been overstated and overgeneralized. Family therapists have probably overused the practice of substituting a benign label for a(More)
OBJECTIVE To evaluate state-of-the-art unsupervised methods on the word sense disambiguation (WSD) task in the clinical domain. In particular, to compare graph-based approaches relying on a clinical knowledge base with bottom-up topic-modeling-based approaches. We investigate several enhancements to the topic-modeling techniques that use domain-specific(More)
This article presents a method for conducting a couple session that illustrates a theoretically valid role for action techniques (as opposed to verbal methods) in post-Milan systemic interviewing. Useful in an opening meeting or in consultation, it pointedly activates client resources while deemphasizing current problems. The interview format begins with(More)
