A Study of Fuzzy Relational Database
The present work deals with detail study of func- tional dependency in fuzzy relational databases. The paper is an extension of the work done by Al-Hamouz and Biswas (1). Here, the f-Armstrong's axioms of (1) have been modified with verification and the well-known concepts of partial ffd, fuzzy key, fuzzy closure of attribute(s) and redundant ffd have been studied with the new notion of fi-ffd as defined in (1). Finally fuzzy key and fuzzy closure of attribute(s) have been tested with a real life example. Copyright c
In TREC2004, Dublin City University took part in three tracks, Terabyte (in collaboration with University College Dublin), Genomic and Novelty. In this paper we will discuss each track separately and present separate conclusions from this work. In addition, we present a general description of a text retrieval engine that we have developed in the last year to support our experiments into large scale, distributed information retrieval, which underlies all of the track experiments described in this document.
