Ontop: Answering SPARQL queries over relational databases
In this paper we present Ontop, an open-source Ontology Based Data Access (OBDA) system that allows for querying relational data sources through a conceptual representation of the domain of interest, provided in terms of an ontology, to which the data sources are mapped. Key features of Ontop are its solid theoretical foundations, a virtual approach to OBDA that avoids materializing triples and...
متن کاملAnswering queries over incomplete data stream histories
Streams of data often originate from many distributed sources. A distributed stream processing system publishes such streams of data and enables queries over the streams. This allows users to retrieve and relate data from the distributed streams without needing to know where they are located. Stream data is important not only for its current values but also for past values produced. In order to...
متن کاملToward Answering Queries Over Incomplete Data, A Monte Carlo Approach
While most of research work is focused on generating summary or partial snapshot of data by sampling raw databases, we take a reverse direction: generating samples from summary or partial data to answer queries without accessing original complete database. Previous work on data reconstruction aims to recover data deterministically by mapping it to an inverse problem, which is unable to answer p...
متن کاملData complexity of answering conjunctive queries over SHIQ knowledge bases
In [6] the authors give an algorithm for answering conjunctive queries over ALCN R knowledge bases which is coNP in data complexity. Their technique is based on the tableau technique for checking sat-isfiability in ALCN R presented in [2]. In their algorithm, the blocking conditions of [2] are weakened in such a way that the set of models their algorithm yields suffices to check query entailmen...
متن کاملAnswering Arbitrary Conjunctive Queries over Incomplete Data Stream Histories
Streams of data often originate from many distributed sources. A user wanting to query the streams should not need to know from where each stream originates but should be provided with a global view of the streams. R-GMA is a system that integrates distributed data streams to provide a global view of all the streams for users to query. R-GMA has been developed as a grid information and monitori...
