Social Integration: At the Crossroads of Knowledge and Values
The International Laboratory for Social Integration Research (ILSIR) at HSE University studies the challenges faced by vulnerable groups and explores ways to help them participate fully in everyday life. To develop effective solutions, the laboratory’s researchers combine cutting-edge methods with practical fieldwork. In this interview with the HSE News Service, Laboratory Head Elena Iarskaia-Smirnova discusses the laboratory’s work.

Physicists Discover What Happens Inside a Stable Vortex
Large vortices with characteristic spiral arms are often observed in the atmosphere and the ocean. Physicists from HSE University have explained how these structures form and why they retain their shape. The researchers found that velocities at points located along the same vortex arc remain correlated even over long distances. At the same time, this correlation weakens rapidly with increasing distance from the vortex centre. These differences help explain the formation of spiral arms and may improve models of atmospheric and oceanic currents. The findings have been published in Physical Review Fluids.

Ontology-Based Data Access: Ontop of Databases

Ch. 35. P. 558–573.
Rodríguez-Muro M., Kontchakov R., Zakharyaschev M.

We present the architecture and technologies underpinning the OBDA system Ontop and taking full advantage of storing data in relational databases. We discuss the theoretical foundations of Ontop: the tree-witness query rewriting,T-mappings and optimisations based on database integrity constraints and SQL features. We analyse the performance of Ontop in a series of experiments and demonstrate that, for standard ontologies, queries and data stored in relational databases, Ontop is fast, efficient and produces SQL rewritings of high quality.

Many experts in the field of data management believe that the emergence of non-volatile byte-addressable main memory (NVM) available for practical use will lead to the development of a new type of ultra-high-speed database management systems (DBMS) with single-level data storage (native in-NVM DBMS). However, the number of researchers who are actively engaged in research ...

Bi-objective Optimization for Approximate Query Evaluation.
Yarygina A., Novikov B., , in: New Trends in Databases and Information Systems. ADBIS 2015Vol. 539: ommunications in Computer and Information Science.: Springer, 2015.
A problem of effective and efficient approximate query evaluation is addressed as a special case of multi-objective optimization with 2 criteria: the computational resources and the quality of result. The proposed optimization and execution model provides for interactive trade of quality for speed. ...

ptimizing resource allocation for approximate real-time query processing.

Queryoptimizationtechniquesareprovedtobeessentialforhighperfor- mance of database management systems. In the context of new querying paradigms, such as similarity based search, exact query evaluation is neither computationally feasible nor meaningful, and approximate query evaluation is the only reasonable option. In this paper a problem of resource allocation for approximate evaluation of com- plex queries is considered. An approximate algorithm ...

Temporal Description Logic for Ontology-Based Data Access
Artale A., Kontchakov R., Wolter F. et al., , in: Proceedings of the 23rd International Joint Conference on Artificial Intelligence.: Beijing: AAAI Press, 2013. Ch. 112 P. 711–718.
Our aim is to investigate ontology-based data access over temporal data with validity time and ontologies capable of temporal conceptual modelling. To this end, we design a temporal description logic, TQL, that extends the standard ontology language OWL 2 QL, provides basic means for temporal conceptual modelling and ensures first-order rewritability of conjunctive queries for ...

New Technology Trends Watch: An Approach and Case Study
Irina V. Efimenko, Khoroshevsky V. F., Lecture Notes in Computer Science 2014 No. 8722 P. 170–177
A hybrid approach to automated identification and monitoring of technology trends is presented. The hybrid approach combines methods of ontology based information extraction and statistical methods for processing OBIE results. The key point of the approach is the so called ‘black box’ principle. It is related to identification of trends on the basis of heuristics ...

OntoQuad: Native High-Speed RDF DBMS for Semantic Web
Potocki A., Polukhin A., Drobyazko G. et al., , in: Knowledge Engineering and the Semantic Web. 4th Conference, KESW 2013, St. Petersburg, Russia, October 7-9, 2013. ProceedingsVol. 394.: Berlin: Springer, 2013. P. 171–131.
In the last years native RDF stores made enormous progress in closing the performance gap compared to RDBMS. This albeit smaller gap, however, still prevents adoption of RDF stores in scenarios with high requirements on responsiveness. We try to bridge the gap and present a native RDF store “OntoQuad” and its fundamental design principles. Basing ...
