Classification, Analysis and Navigation Tools for Physics Research Communication

点击翻译按钮获取中文摘要

Research will be carried out aimed at improving usability of the Electronic Preprint Archive, a web-based, interactive repository of over 250,000 full text articles in physics and related disciplines used heavily by these communities, and, increasingly, serving as a model for such systems and libraries in other fields of science and engineering in the U.S. and abroad. For this purpose, the structure of the archive will be explored using document content data, citation tree data, and usage data. Automatic text classification and document clustering techniques will be developed and used for cleaning, building, and maintaining the subject classification structure. Usage data logs will be used to mine for functional improvements to the Archive. Burst analysis of words in document titles will be used to map trends and, together with citation data, to visualize and navigate the literature. This work will provide new tools useful for continued development of open access systems starting to be used as research libraries in a number of fields, including medicine.
