The detector final state is the core element of particle physics analysis as it defines the physical characteristics that form the basis of the measurement presented in a published paper. Although they are a crucial part of the research process, detector final states are not yet formally described, published in papers or searchable in a convenient way. This paper aims at providing an ontology pattern for the detector final state that can be used as a building block for an ontology covering the whole particle physics analysis life cycle.

We present D-SPARQ, a distributed RDF query engine that combines the MapReduce processing framework with a NoSQL distributed data store, MongoDB. The performance of processing SPARQL queries mainly depends on the efficiency of handling the join operations between the RDF triple patterns. Our system features two unique characteristics that enable efficiently tackling this challenge: 1) Identifying specific patterns of the input queries that enable improving the performance by running different parts of the query in a parallel mode. 2) Using the triple selectivity information for reordering the individual triples of the input query within the identified query patterns. The preliminary results demonstrate the scalability and efficiency of our distributed RDF query engine.

Due to recent developments in reasoning algorithms of the\ various OWL profiles, the classification time for an ontology has come\ down drastically. For all of the popular reasoners, in order to process\ an ontology, an implicit assumption is that the ontology should fit in\ primary memory. The memory requirements for a reasoner are already\ quite high, and considering the ever increasing size of the data to be\ processed and the goal of making reasoning Web scale, this assumption\ becomes overly restrictive. In our work, we study several distributed\ classification approaches for the description logic EL+ (a fragment of OWL 2 EL profile). We present the lessons learned from each approach, our current results, and plans for future work.

It transcends previous work on circumscriptive description logics which had the drawback of yielding an undecidable logic unless severe restrictions were imposed. In particular, it was not possible, in general, to apply local closure to roles. In this paper, we provide a new approach, called grounded circumscription, which is applicable to SROIQ and other description logics around OWL without these restrictions. We show that the resulting language is decidable, and we derive an upper complexity bound. We also provide a decision procedure in the form of a tableaux algorithm.}, doi = {10.1007/978-3-642-25073-6_39}, author = {Kunal Sengupta and Adila Krisnadhi and Pascal Hitzler}, editor = {Lora Aroyo and Chris Welty and Harith Alani and Jamie Taylor and Abraham Bernstein and Lalana Kagal and Natasha F.
