2. About us
• Eventos was founded in 2010 as a R&D division
of Avicomp Services & Ontos AG
• Completed projects
– 2010 – “News planner” with semantic notations for
RIA Novosti
– 2011 – First major research project - LOD 5 mln. USD
– 2012 – Open Data portal for Moscow city
administration
– 2010 – 2013 – Company turnover 10 mln. USD

3. About us
• Team of 60 people with vast exp. in semantic
technology, including:
– Natural Language Processing
– Document clusterization and classification
– Semantic Storage

4. Natural Language Processing
• Rule based NLP engine (2003 -)
– Ontos Miner based on Gate technology
– Russian, English, German, French
– 80-90% precision and recall accuracy
• Rule based NLP + statistics (2011 - )
– Vector machines support technology
– Rule based system supplies statistical machine with
language specific data
(morphology, gazetteer, recognized objects)
– More language independence has become available

5. Document clusterization and classification
• Combination of statistical and semantic
algorithms
• Context awareness
• Summarization – automatic generation of 5-6
sentences of smooth text from texts of 10-100
articles

6. Technology of topic detection

7. Summary example

8. Semantic Storage – OntoQuad RDF
• R&D since 2005
• RDF DB native engine
• Quad type of RDF (named graph notation
supplements each triple)
• Global Object Identification subsystem
• Platforms: Linux, Windows, Android & iOS
• Light on resources (Raspberry Pi tested)
• Accomplished projects:
– “LOD for Digital Science” under aegis of Ministry of Edu.
– City of Moscow – Open Data Portal
– RIA Novosti mass media company

9. OntoQuad RDF Store - benchmarking
• Berlin SPARQL Benchmark (BSBM)
– “Explore” use case scenarios results
– “BI” use case scenarios will be test ready by autumn
2013

10. Summary
• Our plans before 2014
– RIA Novosti RDF Open data store like
data.nytimes.com, BBC, AP
– Inference engine for OntoQuad RDF Store (OWL DL
+ BI testcases for BSBM)
– Scalability for OntoQuad RDF Store
– Mobile application for Android and iOS to promote
LOD and OntoQuad RDF store
