Web-Based Measure of Semantic Relatedness
This paper explores the use of a semantic relatedness measure between words, that uses the Web as knowledge source, and defines a new semanticrelatedness measure among ontology terms that fulfils the above mentioned desirable properties to be used on the Semantic Web.
Querying the web: a multiontology disambiguation method
The proposed method processes a set of related keywords in order to discover and extract their implicit semantics, obtaining their most suitable senses according to their context and applies an iterative disambiguation algorithm that uses a semantic relatedness measure based on Google frequencies.
Ontology Matching with CIDER: Evaluation Report for the OAEI 2008
A schema-based alignment algorithm compares each pair of ontology terms by extracting their ontological contexts up to a certain depth and combining different elementary ontology matching techniques, which shows a very good behaviour in terms of precision, while preserving an acceptable recall.
Ontology matching with CIDER: evaluation report for OAEI 2011
In this new approach, the burden of manual selection of weights has been definitely eliminated, while preserving the performance with respect to CIDER’s previous participation in the benchmark track (at OAEI’08), and areas of potential improvement are discovered.
Spider: Bringing Non-equivalence Mappings to OAEI
A carrier for electronic components which generate heat during their operation, such as high power semiconductors, is disclosed and includes complementary ends which are designed to conserve space when more than one carrier is mounted on a substrate containing an electronic circuit.
DynaLearn - An Intelligent Learning Environment for Learning Conceptual Knowledge
An overview of the DynaLearn system, an Intelligent Learning Environment that allows learners to acquire conceptual knowledge by constructing and simulating qualitative models of how systems behave, uses diagrammatic representations for learners to express their ideas.
The apertium bilingual dictionaries on the web of data
This paper describes the conversion of the Apertium family of bilingual dictionaries and lexicons into RDF (Resource Description Framework) and how their data have been made accessible on the Web as linked data.
Leveraging RDF Graphs for Crossing Multiple Bilingual Dictionaries
The experiments presented here exploit the properties of the Apertium RDF Graph, principally cycle density and nodes’ degree, to automatically generate new translation relations between words, and…
Discovering the Semantics of User Keywords
A system that takes as input a list of plain keywords pro- vided by a user and translates them into a query expressed in a formal language without ambiguity, which discovers the semantics of user keywords by consulting the knowledge represented by many (heterogeneous and distributed) ontologies.
