Data access in an enterprise setting is a determining factor for value creation processes, such as sense making, decision making, and intelligence analysis. Particularly, in an enterprise setting, intuitive data access tools that directly engage domain experts with data could substantially increase competitiveness and profitability. In this respect, the use of ontologies as a natural communication medium between end users and computers has emerged as a prominent approach. To this end, this article introduces a novel ontology-based visual query system, named OptiqueVQS, for end users. OptiqueVQS is built on a powerful and scalable data access platform and has a user-centric design supported by a widget-based flexible and extensible architecture allowing multiple coordinated representation and interaction paradigms to be employed. The results of a usability experiment performed with non-expert users suggest that OptiqueVQS provides a decent level of expressivity and high usability, and hence is quite promising.Keywords Visual query formulation · visual query systems · ontology-based data access · data retrieval 1 Introduction

“…There are several academic and industrial systems for OBDA or that are very similar to OBDA in spirit. Mastro [14], morph-RDB [15], and Ontop [16] support ontology reasoning and thus address Requirement R3, while D2RQ [17], OntoQF [18], Virtuoso 3 , Spyder 4 , and Ultrawrap [19] do not support reasoning and thus fail Requirement R3. Moreover, all these systems fail Requirement R2: Ultrawrap, Ontop, Mastro, and morph-RDB lack user-oriented query formulation interfaces and query visualisation, since they only provide SPARQL end-points and predefined queries; while OntoQF considers ontology queries as OWL statements and has no visual query formulation support.…”

We present a description and analysis of the data access challenge in Siemens Energy. We advocate Ontology Based Data Access (OBDA) as a suitable Semantic Web driven technology to address the challenge. We derive requirements for applying OBDA in Siemens, review existing OBDA systems and discuss their limitations with respect to the Siemens requirements. We then introduce the Optique platform as a suitable OBDA solution for Siemens. The platform is based on a number of novel techniques and components including a deployment module, BootOX for ontology and mapping bootstrapping, a query language STARQL that allows for a uniform querying of both streaming and static data, a highly optimised backend, ExaStream, for processing such data, and a query formulation interface, OptiqueVQS, that allows to formulate STARQL queries without prior knowledge of its formal syntax. Finally, we describe our installation and evaluation of the platform in Siemens.

“…OWL is a formal language for representing ontologies in the Semantic Web [12]. This language has been used in many specific scenarios for the construction of flexible data semantic models [9,13,14]. Several knowledge organization systems takes advantage of semantic web technologies [18,11,8], SKOS [18] is one of them.…”

Abstract. Authority control is recognized as an expensive task in the cataloging process. This is actually an active research field in libraries and related research institutions even when several approaches have been proposed in this research area. In this paper, we propose AUCTORITAS, a tool for exposing high value services on the web for the authority control in a generic institution environment. This paper describes the application ecosystem behind AUCTORITAS and how the semantic web languages make possible the semantic integration of heterogeneous applications. Likewise we evaluate the applicability of the proposal for academic libraries.
