The concept of “approximate” searching has applications in a vast number of fields. Some examples are non-traditional databases (e. g. storing images, fingerprints or audio clips, where the concept of exact search is of no use and we search instead…

EQUIVALENCE OF SOME STRINGS. THESE ARE LOWERCASE VERUS UPPERCASE MATCHING, MORPHOLOGICAL INFLECTION, DERIVATION, AND SYNONYMY OF WORDS: E.G. GIVE A QUERY COMPUTER, FIND COMPUTER COMPUTING, WORKSTATION. THE LATTER PROBLEMS ARE VERY IMPORTANT IN LANGUAGES WITH RICHER MORPHOLOGY AND LESS STABLE…

The Semantic Web attempts to reach a state in the future where everything on the Web will no longer be only machine-readable, but also machine-understandable. An ontology is an explicit specification of a conceptualization. A conceptualization is an abstract, simplified…

Vertical partitioning, in which attributes of a relation are
assigned to partitions, is aimed at improving database
performance. We extend previous research that is based on
a single relation to multi-relation database environment,
by including referential integrity constraints, access time

Este artículo presenta un método de identificación y clasificación de la valencia y las
emociones presentes en un texto. Para ello, se introduce un nuevo concepto denominado

THE GOAL OF THIS PAPER IS TO DOCUMENT THE USE OF TIME SERIES IN COLOR MATCHING. ALTHOUGH TIME SERIES ARE NOT COMMONLY USED FOR THIS PURPOSE, THE RESULTS OBTAINED, BASED ON THE PRINCIPLE OF SIMILARITY IN TIME SERIES USING THE…

This book provides an excellent foundation for the principles of database and data management. It explains some of the more difficult concepts fairly well. The book is meant for an introductory course in database management which is usually required as…

Software engineering has entered a new era, the Internet and its associated technologies require a different conceptual framework for building and understanding software solutions.
Users ask to develop applications more rapidly, and software engineers need to ensamble systems from preexisting…

Similarity search is a fundamental operation for applications that deal with unstructured data sources. In this paper we propose a new pivot-based method for similarity search, called Sparse Spatial Selection (SSS).
The main characteristic of this method is that it…
