Incremental Reasoning on RDF Streams [chapter]

Daniele Dell'Aglio, Emanuele Della Valle
2014 Emerging Directions in Database Systems and Applications  
Related works The origin of the approach, which we follow in this work, can be found in incremental maintenance of materialized views in deductive databases [7, 14] .  ...  They proved that when the number of modification in the database is under a threshold, the incremental maintenance techniques perform orders of magnitude faster than the whole re-computation of the view  ...

Incremental Reasoning on Streams and Rich Background Knowledge [chapter]

Davide Francesco Barbieri, Daniele Braga, Stefano Ceri, Emanuele Della Valle, Michael Grossniklaus
2010 Lecture Notes in Computer Science  
Our contribution is a new technique that exploits the nature of streaming data in order to efficiently maintain materialized views of RDF triples, which can be used by a reasoner.  ...  Previous work, delivered in the context of deductive databases, describes the use of logic programming for the incremental maintenance of such entailments.  ...  We elaborate on previous papers [9, 10] that extend to logic programming results from incremental maintenance of materialized views in deductive databases [11] .  ...

Taming velocity and variety simultaneously in big data with stream reasoning

Emanuele Della Valle, Daniele Dell'Aglio, Alessandro Margara
2016 Proceedings of the 10th ACM International Conference on Distributed and Event-based Systems - DEBS '16  
Many "big data" applications must tame velocity (processing data in-motion) and variety (processing many different types of data) simultaneously.  ...  On the other hand, the event and stream processing community has focused on the velocity of data, producing systems that efficiently operate on streams of data on-the-fly according to pre-deployed processing  ...  The origin of incremental maintenance approach can be found in maintenance of materialized views in active databases [21, 60] .  ...

Marco A. Casanova, Vânia M. P. Vidal, Giseli Rabello Lopes, Luiz André P. Paes Leme, Livia Ruback
2014 Lecture Notes in Computer Science  
The Linked Data initiative promotes the publication of previously isolated databases as interlinked RDF datasets, thereby creating a global scale data space.  ...  Datasets are frequently interlinked using some automated matching process that results in a materialized sameAs linkset, that is, a set of links of the form (s, owl:sameAs, o), which asserts that s denotes  ...  as the Web of Data.  ...

ODIN: A Dataspace Management System

Sergi Nadal, Kashif Rabbani, Oscar Romero, Shumet Tadesse
2019 International Semantic Web Conference  
Odin is a system that supports the incremental pay-as-yougo integration of data sources into dataspaces and provides user-friendly querying mechanisms on top of them.  ...  Odin automatically extracts the schemata from structured (e.g., relational) and semi-structured (e.g., JSON) data sources and translates them into a canonical data model, namely RDFS.  ...  ., relational or JSON), a set of pre-defined production rules (i.e., tuple-generating dependencies defined at the meta-model level) generate an equivalent RDFS model 2 .  ...
