Towards Query Formulation, Query-Driven Ontology Extensions in OBDA Systems
نویسندگان
چکیده
The process of translating end-users’ information needs into executable and optimised queries over the data is the main problem that end-users face in Big Data scenarios. In this paper we present the recently started EU project Optique, which advocates for a next generation of the well known Ontology-Based Data Access (OBDA) approach to address this problem. We discuss challenges, present ongoing work, and our current preliminary solutions with regards to the query formulation and query-driven ontology extension.

OptiqueVQS: a Visual Query System over Ontologies for Industry
An important application of semantic technologies in industry has been the formalisation of information models using OWL 2 ontologies and the use of RDF for storing and exchanging application data. Moreover, legacy data can be virtualised as RDF using ontologies following the ontology-based data access (OBDA) approach. In all these applications, it is important to provide domain experts with qu...

Motivation Ontology Based Data Access (OBDA) [16] is a recently proposed prominent approach that aims at providing domain experts with a direct access to available enterprise data sources without IT-experts being involved. OBDA is an alternative to centralised approaches, where an IT-expert translates the requirements of domain experts into Extract-Transform-Load (ETL) processes to first integr...

A b s t r a c t . Query rewriting is one of the fundamental steps in ontologybased data access (OBDA) approaches. It takes as inputs an ontology and a query written according to that ontology, and produces as an output a set of queries that should be evaluated to account for the inferences that should be considered for that query and ontology. Different query rewriting systems give support to d...

Due to the increasing web, there are many challenges to establish a general framework for data mining and retrieving structured data from the Web. Creating an ontology is a step towards solving this problem. The ontology raises the main entity and the concept of any data in data mining. In this paper, we tried to propose a method for applying the "meaning" of the search system, But the problem ...

Ontology-based data access (OBDA) has recently emerged as a promising application of knowledge representation and reasoning technologies in information management systems. The aim of OBDA is to facilitate access to data that is significantly heterogeneous and incomplete. This is achieved via an ontology that provides a unified conceptual view of the data, and makes it accessible via database qu...
