Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions.

Towards better entity resolution techniques for Web document collections

Karl Aberer, Zoltán Miklós, Surender Reddy Yerva

As person names are non-unique, the same name on different Web pages might or might not refer to the same real-world person. This entity identification problem is one of the most challenging issues in realizing the Semantic Web or entity-oriented search. W ...

Incremental Query Evaluation in a Ring of Databases.

Christoph Koch

This paper approaches the incremental view maintenance problem from an algebraic perspective. We construct a ring of databases and use it as the foundation of the design of a query calculus that allows to express powerful aggregate queries. The query calcu ...

Functional dependencies in OWL ABoxes

Jean Paul Calbimonte Perez

Functional Dependency (FD) has been extensively studied in database theory. Most recently there have been some works investigating the implications of extending Description Logics with functional dependencies. In particular the OWL ontology language offers ...

Context aware, multimodal, and semantic rendering engine

Daniel Thalmann, Patrick Salamin

Nowadays, several techniques exist to render digital content such as graphics, audio, haptic, etc. Unfortunately, they require different faculties that cannot always be applied, e.g. providing a picture to a blind person would be useless. In this paper, we ...

Visual creation of inhabited 3D environments: An ontology-based approach

Daniel Thalmann, Alejandra Garcia Rojas Martinez

The creation of virtual reality applications and 3D environments is a complex task that requires good programming skills and expertise in computer graphics and many other disciplines. The complexity increases when we want to include complex entities such a ...

Conceptual Synopses of Semantics in Social Networks Sharing Structured Data

We are interested in the problem of data sharing in overlay networks that have a social structure, i.e. participants are linked and exchange data with others w.r.t. the similarity of their data semantics. In this paper we propose a methodology to produce c ...

Methods of inferring user preferences using ontologies

Boi Faltings, Vincent Jean Fabrice Schickel

Methods of inferring user preferences using ontologies use ontology structure based similarity and an inference mechanism in defining ontology filtering (OF). Items are recommended to users by identifying items that the users may prefer, but may not have b ...

Extending OWL with Explicit Dependency

Jean Paul Calbimonte Perez

Functional Dependency has been extensively studied in database theory. It provides an elegant formalism for specifying key constraints and is the basis for normalization theory used in Relational database design. Given its known axiomatization through logi ...
