Indexing source descriptions based on defined classes

Ralph Lange, Frank Dürr, Kurt Rothermel
2010 Proceedings of the Fourteenth International Database Engineering & Applications Symposium on - IDEAS '10  
The formalism refines existing approaches that describe the sources by constraints on the attribute value ranges in several ways: It allows for complex, nested descriptions based on defined classes.  ...  We further propose the SDC-Tree for indexing such source descriptions.  ...  We further propose the Source Description Class Tree (SDC-Tree) for indexing source descriptions by means of their defined classes.  ...

Integration of OWL Ontologies in MPEG-7 and TV-Anytime Compliant Semantic Indexing [chapter]

Chrisa Tsinaraki, Panagiotis Polydoros, Stavros Christodoulakis
2004 Lecture Notes in Computer Science  
We present the details of the methodology and the implementation of the tools supporting it as well as its integration in a large framework for domain-specific indexing and retrieval of audiovisual content  ...  We describe a systematic methodology for extending the audiovisual content description standards (MPEG-7 and TV-Anytime) with domain-specific knowledge descriptions expressed in OWL.  ...  The indexing process is guided by appropriate domain-specific ontologies, which are based on the Semantic Part of the MPEG-7 MDS and are defined using the syntax of the OWL language.  ...

Integrating ontologies and thesauri for RDF schema creation and metadata querying

Bernd Amann, Irini Fundulaki, Michel Scholl
2000 International Journal on Digital Libraries  
We will present a fairly simple database-oriented solution for querying such metadata which avoids a (recursive) tree traversal and is based on a linear encoding of thesaurus hierarchies.  ...  This integration is based on the specification of inclusion relationships between thesaurus terms and ontology concepts and results in application-specific metadata schemas incorporating the structural  ...  Acknowledgments We would like to thank Vassilis Christophides for his precious comments on preliminary versions of this paper.  ...

Code generator generation based on template-driven target term rewriting [chapter]

Annie Despland, Monique Mazaud, Raymond Rakotozafy
1987 Lecture Notes in Computer Science  
Our approach is based on a target machine description where the basic concepts used (access modes, access classes and instructions) are bottom-up hierarchically described by tree-patterns, These tree-patterns  ...  The first phase of code production is based on access mode template-driven rewritings in which the program intermediate representation is progressively transformed into its "canonical form'*.  ...  So, we define two fundamental concepts: storage base and storage class.  ...

Discovering likely mappings between APIs using text mining

Rahul Pandita, Raoul Praful Jetley, Sithu D Sudarsan, Laurie Williams
2015 2015 IEEE 15th International Working Conference on Source Code Analysis and Manipulation (SCAM)  
To address the shortcoming, this paper proposes TMAP: Text Mining based approach to discover likely API mappings using the similarity in the textual description of the source and target API documents.  ...  We compared the discovered mappings with state-of-the-art source code analysis based approaches: Rosetta and StaMiner.  ...  During the indexing process, a document (a sequence of text) is divided into its constituent units, known as tokens or terms, based on a well-defined criterion.  ...

Automatic Semantic Description Extraction from Social Big Data for Emergency Management

Bukhoree Sahoh, Anant Choksuriwong
2020 Journal of Systems Science and Systems Engineering  
The solution is an automatic approach to knowledge discovery, and we propose a semantic description technique based on the use of triple store indexing for named entity recognition and relation extraction  ...  The main objectives of emergency management are to provide human safety and security, and Social Big Data (SBD) offers an important information source, created directly from eyewitness reports, to assist  ...  A triple store index for semantic descriptions requires semantically graphical knowledge, or an ontology, as a triple store, based on the emergency domain.  ...

2006 IEEE John Vincent Atanasoff 2006 International Symposium on Modern Computing (JVA'06)  
In this paper, we will introduce to describe learning resources by using ontology model based on metadata of learning standard as Sharable Content Object Reference Model (SCORM) and Dublin Core metadata  ...  The designing of metadata structure has followed the standard metadata and we have added some categories and elements to managing the indexation and classification.  ...  This structure is based on SCORM metadata and implemented by means of ontology model. We added new category and elements to indexing, classification, grouping of learning resources.  ...

Knowledge Intensive Case-Based Assistance for Framework Reuse* [chapter]

Mercedes Gómez-Albarrán, Pedro A. González-Calero
2001 Lecture Notes in Computer Science  
Our knowledge intensive Case-Based Reasoning approach faces the reuse of frameworks using cases that correspond to framework usage experiences.  ...  The class in the solution depends on that case index feature. The method depends on the class. So, the class and the method should be adapted.  ...  The case index (the terminological description of the problem) is the individual representing the query used to retrieve the source case.  ...
