ABSTRACT: Probability-based text clustering algorithm by alternately repeating two operations

Abstract Owing to the rapid advance of internet technology, users have to face to a large amount of raw data from the World Wide Web every day, most of which is displayed in text format. This situation brings a great demand for efficient text analysis techniques by internet users. Since clustering

MANUSCRIPT: Sharing data for the public good and protecting individual privacy: informatics solutions to combine different goals

Data sharing requires an environment in which the professionals who handle the data adhere to the highest ethical standards and implement systematic processes that (a) measure data quality, (b) respect to consumer preferences, (c) successfully identify research cohorts, and (d) are scalable. http://jamia.bmj.com/content/20/1/1.full.pdf html

ABSTRACT: Implementing an interface terminology for structured clinical documentation

Abstract Clinically oriented interface terminologies support interactions between humans and computer programs that accept structured entry of healthcare information. This manuscript describes efforts over the past decade to introduce an interface terminology called CHISL (Categorical Health Information Structured Lexicon) into clinical practice as part of a computer-based documentation application at Vanderbilt

RESOURCE: The Best Assessment Tools for the Online Classroom

This article will discuss some practical methods, which have been empirically tested and experimented both in the classroom and in "distance" delivery. New methods, which are either low cost or no cost for the instructor or end-user, will also be discussed. Some of these are already known as Web 2.0

RESOURCE: Informatics Professor: Implementing the Learning Healthcare System Can Be Facilitated Using the Principles of Evidence-Based Medicine

The enthusiasm for big data and for the use of analytics and business intelligence with that data is reaching a fevered pitch. I share that enthusiasm, but also know from both my clinical and my informatics experience that knowledge will not emanate just by turning on the data spigot from

MANUSCRIPT: Towards comprehensive syntactic and semantic annotations of the clinical narrative — Albright et al. — Journal of the American Medical Informatics Association

Abstract Objective To create annotated clinical narratives with layers of syntactic and semantic labels to facilitate advances in clinical natural language processing (NLP). To develop NLP algorithms and open source components. Methods Manual annotation of a clinical narrative corpus of 127 606 tokens following the Treebank schema for syntactic information, PropBank schema for

ABSTRACT: The intended and unintended consequences of communication systems on general internal medicine inpatient care delivery: a prospective observational case study of five teaching hospitals — Wu et al. — Journal of the American Medical Informatics Association

Abstract Background Effective clinical communication is critical to providing high-quality patient care. Hospitals have used different types of interventions to improve communication between care teams, but there have been few studies of their effectiveness.Objectives To describe the effects of different communication interventions and their problems.Design Prospective observational case study using a

MANUSCRIPT: How is a search system used in work task completion?

Abstract Typically studies of information retrieval and interactive information retrieval concentrate on the identification of relevant items. In this study, rather than stop at finding relevant items, we considered how people use a search system in the completion of a broader work task. To conduct the study, we created 12 tasks that required

ABSTRACT: Federated queries of clinical data repositories: the sum of the parts does not equal the whole — Weber — Journal of the American Medical Informatics Association

Abstract Background and objective In 2008 we developed a shared health research information network (SHRINE), which for the first time enabled research queries across the full patient populations of four Boston hospitals. It uses a federated architecture, where each hospital returns only the aggregate count of the number of patients who
