By Javier Lacasta, Javier Nogueras-Iso, Francisco Javier Zarazaga Soria

Information infrastructures are built-in options in line with the fusion of knowledge and communique applied sciences. they're characterised through the big quantity of information that has to be controlled consequently. a data infrastructure calls for an effective and powerful details retrieval approach to supply entry to the goods saved within the infrastructure. Terminological Ontologies: layout, administration and useful purposes offers the most difficulties that have an effect on the invention structures of data infrastructures to regulate terminological versions, and introduces a mix of study instruments and functions in Semantic net applied sciences. This booklet particularly analyzes the necessity to create, relate, and combine the types required for an infrastructure via elaborating at the challenge of gaining access to those versions in a good demeanour through interoperable providers and components.

About this publication: • comprises the typical framework for integration of terminological types into info infrastructures, masking different administration steps (acquisition, garage, and access). • offers a revision of the most specifications of terminological types in several info retrieval structures and proposes integration recommendations to facilitate and simplify its administration. • “This publication is vital in the event you should create ontologies from latest terminological databases,” reviews Dr. Jacques Teller, collage Of Liege, Belgium.

Terminological Ontologies: layout, administration and sensible functions is aimed at details administration platforms and semantic net execs operating as venture managers, software builders, executive employees and extra. complex undergraduate and graduate point scholars, professors and researchers targeting desktop technology also will locate this e-book invaluable as a secondary textual content or reference publication.

Knowledge Representation and the Semantics of Natural Language

The booklet provides an interdisciplinary method of wisdom illustration and the therapy of semantic phenomena of common language, that is located among synthetic intelligence, computational linguistics, and cognitive psychology. The proposed approach is predicated on Multilayered prolonged Semantic Networks (MultiNets), that are used for theoretical investigations into the semantics of average language, for cognitive modeling, for describing lexical entries in a computational lexicon, and for normal language processing (NLP).

Web data mining: Exploring hyperlinks, contents, and usage data

Internet mining goals to find worthwhile details and information from internet links, web page contents, and utilization facts. even supposing internet mining makes use of many traditional facts mining concepts, it isn't basically an program of conventional facts mining as a result of the semi-structured and unstructured nature of the net information.

Semantic Models for Multimedia Database Searching and Browsing

Semantic versions for Multimedia Database looking out and perusing starts off with the advent of multimedia info functions, the necessity for the advance of the multimedia database administration platforms (MDBMSs), and the real concerns and demanding situations of multimedia structures. The temporal relatives, the spatial kin, the spatio-temporal relatives, and several other semantic versions for multimedia info platforms also are brought.

Enterprise Content Management in Information Systems Research: Foundations, Methods and Cases

This e-book collects ECM examine from the educational self-discipline of data platforms and similar fields to help lecturers and practitioners who're attracted to figuring out the layout, use and influence of ECM structures. It additionally offers a useful source for college students and academics within the box. “Enterprise content material administration in info structures examine – Foundations, tools and circumstances” consolidates our present wisdom on how today’s companies can deal with their electronic details resources.

A first family is the one based on frames such as the described by Minsky [143], Fikes and Kehler [54], that are used in knowledge tools such as Prot´eg´e [158] and Ontolingua Server [50], CycLp [128] or the Frame Logic lan- 18 1 Ontology basic concepts guage used by OntoEdit20 [183]. Another family is based on Description Logics such as Classic [20], KIF [61], its successor CL [89] and Ontolingua language [70] (also based on KIF). OWL [16] has also an explicit logical basis for the language based on description logics, but the limitations of the RDF-Schema based representations make difficult the expression of some types of predicates (see Horrocks and Patel-Schneider [78]).

Its opposite is hypernymy. , cow, bull). org/ 20 1 Ontology basic concepts they can be considered equivalent for search purposes. Therefore, the equivalence between them has to be stated. Translations: Terms from different languages can also be equivalents in the way described by synonymy (having exactly the same meaning). However, is much more habitual to have terms in different languages that only partially overlap in meaning, making difficult the definition of equivalence relations. Most ontology models are able to represent subsets of these relations.

They are domain or application models that contain the terminology required in an area of knowledge for a specific application and along the years, they have proven to be a useful tool to deal with ambiguity problems, providing inter-relation structure and semantics to the terminology used in these systems. Nowadays, there is a great deal of terminological models covering every area of interest and they have become a crucial part of the information retrieval systems of digital libraries, catalogues and any other system where information is searched or presented thematically.
