It is thus critical to establish links between these data, both for the web of data and for the semantic web that it contributes to feed. We consider here the various techniques developed for that purpose and analyze their commonalities and differences. We propose a general framework and show how the diverse techniques fit in the framework.

In this paper, we present a workflow for publishing and linking transport data on the Web. So we will be able to develop transport applications and to add other features which will be created from other datasets. This will be possible because transport data will be linked to these datasets.

This deliverable focusses on the definition of a delivery alignment format for tools producing alignments (mapping tools). It considers the many formats that are currently available for expressing alignments and evaluate them with regard to criteria that such formats would satisfy. It then proposes some improvements in order to produce a format satisfying more needs.

One of the solutions is to designing mappings that link the corresponding entities. Many systems and algorithms have been built by different parties, but each system represents the mappings in its own format. To allow reusability of the mapping tools and of the results of the algorithms, we have designed a language to express these mappings.

This language, together with the mapping patterns, allows the user to more easily identify mappings and to describe mappings in an intuitive way. The mappings are organized in a library in a hierarchical fashion in order to allow for easy browsing and retrieving of mappings. Keyword list: Ontology Mapping, Mapping Patterns, Patterns Library

Les outils et méthodologies actuels de conception d'ontologies proposent des services de débogage pour aider à la réalisation de cette tâche.

It has been achieved by extending tuple space computing to support RDF as triple space computing. It can play an important role by acting as global middleware providing support for collaboration of different semantic technologies.

Correspondence patterns capture regularities recurring when aligning ontologies. They come in complement of ontology matching algorithms and graphical mapping tools, and facilitate the task of the engineer building the alignment between a pair of ontologies. We develop an ontology mediation framework based on three ontology correspondence abstraction levels.

We propose to use three levels representing a degree of structuration, from manually annotated documents at the basic level to complex ontology based information. We formulate” hops” allowing to go from one level to the next using data mining and information retrieval techniques. We illustrate our framework by structuring an annotated web documents corpus.

As the wealth of data on the World Wide Web grows, and as the structuring of that data improves, more sophisticated applications can be developed to derive meaningful characteristics relating to the content and structure of that data. In particular, ranking the various elements of sets of structured information is of great utility with respect to semantic network analysis.

It is thus critical to establish links between these data, both for the Web of data and for the Semantic Web that it contributes to feed. We consider here the various techniques which have been developed for that purpose and analyze their commonalities and differences. This provides a general framework that the diverse data linking systems instantiate.

Apres un rappel des notions essentielles et un bref état de l'art, nous y présentons les outils pour l'extraction de graphes et les méthodes pour réaliser des croisements sémantiques entre un verbe et un noma l'intérieur du graphe du dictionnaire, développés au cours du stage. Les résultats de ces méthodes sont ensuite brievement comparés et des perspectives d'application entrevues.

Ontology antipatterns are structures that reflect ontology modelling problems because they lead to inconsistencies, bad reasoning performance or bad formalisation of domain knowledge. We propose four methods for the detection of antipatterns using SPARQL queries. We conduct some experiments to detect antipattern in a corpus of OWL ontologies.

It ensures that the published datasets are connected with others on the Web. Many techniques are developed on this topic in order to automate the task of finding similar entities in two datasets. In this deliverable, we first clarify terminology in the field of linking data. Then we classify and overview many techniques used to automate data linking on the web.

On pourrait aller jusqu'à ajouter, en éreintant sans doute plus qu'il n'est nécessaire la célèbre phrase de Clausewitz, qu'elle n'est rien d'autre que la poursuite de la philosophie par d'autres moyens.

Ontology antipatterns are structures that reflect ontology modelling problems, they lead to inconsistencies, bad reasoning performance or bad formalisation of domain knowledge. Antipatterns normally appear in ontologies developed by those who are not experts in ontology engineering. Based on our experience in ontology design, we have created a catalogue of such antipatterns in the past, and in this paper we describe how we can use SPARQL-DL to detect them.

We present an approach to ontology transformation based on transformation patterns, which could assist in many semantic tasks (such as reasoning, modularisation or matching). Ontology transformation can be applied on parts of ontologies called ontology patterns.
