Why Do Nurses Utilize Textual Knowledge Sources at Work?

Understanding collaboration between nurses and physicians as knowledge at work.

BACKGROUND Collaboration between nurses and physicians is linked to positive outcomes for patients, especially in the intensive care unit. However, effective collaboration poses challenges because of traditional barriers such as sex and class differences, hierarchical organizational structures in health-care, and physicians' belief that they are the final arbiter of clinical decisions. OBJECT...

Robust Textual Inference using Diverse Knowledge Sources

We present a machine learning approach to robust textual inference, in which parses of the text and the hypothesis sentences are used to measure their asymmetric “similarity”, and thereby to decide if the hypothesis can be inferred. This idea is realized in two different ways. In the first, each sentence is represented as a graph (extracted from a dependency parser) in which the nodes are words...

Knowledge Sources for Textual CBR Applications

Textual CBR applications address issues that have traditionally been dealt with in the Information Retrieval community, namely the handling of textual documents. As CBR is a knowledge-based technique, the question arises where items of knowledge may come from and how they might contribute to the implementation of a Textual CBR system. In this paper, we will show how various pieces of knowledge ...

Why do color transforms work?

Numerous papers have been written regarding techniques to translate color measurements from an RGB device (such as a scanner or camera) into some standard color space. The papers seem to ignore the mathematical "truth"... that the translation is impossible. Do these color transforms work, or under what conditions do they work, and what are the limitations? Why is it that they work (if they do)?...
