Database management systems are now an indispensable tool for managing information, and a course on the principles and practice of database systems is now an integral part of computer science curricula. This book covers the
fundamentals of modern database management systems, in particular relational database systems.
We have attempted to present the material in a clear, simple style. A quantitative approach is used throughout with many detailed examples.

CL Research began experimenting with massive XML tagging of texts to answer questions in TREC 2002. In DUC 2003, the experiments were extended into text summarization. Based on these experiments, The Knowledge Management System (KMS) was developed to combine these two capabilities and to serve as a unified basis for other types of document exploration. KMS has been extended to include web question answering, both general and topic-based summarization, information extraction, and document exploration. ...

EUFID is a natural language frontend for data management systems. It is modular and table driven so that it can be interfaced to different applications and data management systems. It allows a user to query his data base in natural English, including sloppy syntax and misspellings. The tables contain a data management system view of the data base, a semantic/syntactic view of the application, and a mapping from the second to the first. We are entering a new era in data base access. Computers and terminals have come down in price while salaries have risen. ...
The paper discusses the corpora management system (CMS) design that uses Java and Oracle9i DBMS to support strategic corpora analysis. We present the pilot webbased CMS to support linguists in their daily work. The system offers facilities to assist linguists and internet users as they search for relevant material, and then classify and annotate this material.
