This paper presents a new database containing high-definition audio and video recordings in a rather unconstrained video-conferencing-like environment. The database consists of recordings of people sitting around a table in two separate rooms communicating ...
In today's companies and organizations, databases are omnipresent. They are the means to represent and store information. Therefore, they must evolve whenever the information architecture (semantic and structure) changes. Databases are subject to evolution ...
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 ...
TubercuList (http://tuberculist.epfl.ch/), the relational database that presents genome-derived information about H37Rv, the paradigm strain of Mycobacterium tuberculosis, has been active for ten years and now presents its twentieth release. Here, we descr ...
This document presents an overview of the mobile biometry (MOBIO) database. This document is written expressly for the face and speech organised for the 2010 International Conference on Pattern Recognition. ...
A major obstacle to the development of ontologies in support of the Semantic Web is the poor capability of current ontology techniques to handle very large ontologies, in particular regarding scalability of reasoners. This paper builds on the assumption th ...
We study highly expressive query languages such as datalog, fixpoint, and while-languages on probabilistic databases. We generalize these languages such that computation steps (e.g. datalog rules) can fire probabilistically. We define two possible semantic ...
In the past, the problem of semantic interoperability in information systems was mostly solved by means of centralization, both at a system and at a logical level. This approach has been successful to a certain extent, but offers limited scalability and fl ...
The current design of database drivers – a necessary evil for interacting with a DBMS – imposes undue burdens on those who install, upgrade, and manage database systems and their applications. In this paper, we introduce Drivolution, a new architecture for ...
The gap between the semantic content of multimedia data and its underlying physical representation is one of the main problems in the modern multimedia research in general, and, in particular, in the field of multimedia database modeling. We believe that o ...
