Semantic-Based Case Retrieval of Service Integration Models in Extensible Enterprise Systems Based on a Business Domain Ontology [chapter]

Matthias Allgaier, Markus Heller, Sven Overhage, Klaus Turowski
2011 Lecture Notes in Business Information Processing  
In addition a case retrieval algorithm is proposed, that computes the similarity between two integration cases based on the semantic distance between concepts within the Business Domain Ontology.  ...  A key challenge for the reuse of integration knowledge is to retrieve existing integration cases that have been developed in similar functional areas within the process space of standard enterprise systems  ...  Here, a new problem is solved by retrieving a similar past case, and reusing it in the new situation [2] .  ...

An Extensible Platform for Semantic Classification And Retrieval of Multimedia Resources

Paolo Pellegrino, Fulvio Corno
2006 Semantic Web Applications and Perspectives  
Moreover, the platform uses an ontology as a conceptual representation of a well-defined domain in order to semantically classify and retrieve anchors (and the related resources).  ...  This paper introduces a possible solution to the problem of semantic indexing, searching and retrieving heterogeneous resources, from textual as in most of modern search engines, to multimedia.  ...  In this case, the main task is the interpretation of a description basing on the conceptual domain provided as an ontology to the platform.  ...

Semantic-Driven Matchmaking of Web Services Using Case-Based Reasoning

Taha Osman, Dhavalkumar Thakker, David Al-Dabass
2006 2006 IEEE International Conference on Web Services (ICWS'06)  
In this paper, we present a novel approach that utilizes the case based reasoning methodology for modelling dynamic Web service discovery and matchmaking.  ...  The framework also utilises OWL semantic descriptions extensively for implementing both the components of the CBR engine and the matchmaking profile of the Web services.  ...  Applied to CBR case descriptions for Web services, ontologies can be used to provide a generic, reasoner-independent description of their functional and non-functional parameters.  ...

A Case Study of Structure Processing to Generate a Case Base [chapter]

Hector Gómez-Gauchía, Belén Díaz-Agudo, Pedro A. González-Calero
2004 Lecture Notes in Computer Science  
In this paper we present a semiautomatic methodology for building an ontology-based organization of the Case Base and to populate it with cases extracted from structured documents.  ...  Although Case-based Reasoning is supposed to alleviate the well known knowledge acquisition bottleneck for knowledge-based systems, case acquisition remains an expensive process.  ...  The system shows the text of the slot solution in the retrieved case, that is a brief description of the general functionality related with companies.  ...

The use of mediation and ontology technologies for software component information retrieval

Regina M. M. Braga, Marta Mattoso, Cláudia M. L. Werner
2001 Software engineering notes  
Through mediators, domain ontology acts as a technique/formalism for specifying ontological commitments or agreements between component users and providers, enabling more accurate software component information  ...  We present a component information integration data layer, based on mediators.  ...  For each ontological domain term, it is necessary to register its name, its type (in this specific case a term that represents a functionality in the domain), its importance within the domain and the related  ...

A Declarative Similarity Framework for Knowledge Intensive CBR [chapter]

Belén Díaz-Agudo, Pedro A. González-Calero
2001 Lecture Notes in Computer Science  
Our approach is based on acquiring the domain knowledge by reusing knowledge from a library of ontologies and integrating it with CBROnto, a task based ontology comprising common CBR terminology.  ...  We describe our CBROnto based similarity representation framework and explain how it is used to represent similarity measures and retrieval processes.  ...  That allows complex retrieval processes and an interactive use of the CBR system where the user makes a possibly complex description of the case/s she needs and can judge the quality of the retrieved cases  ...
