Pushing complexity down the stack

The lower bound is proved by examining the decision tree of the deterministic query scheme and exhibiting an input for which the number of queries asked is high.. More precisely,

In the HAQWA (Hash-based and Query Workload Aware) system, we pro- pose a trade-off between data distribution complexity and query answering effi- ciency together with an

The complexity of the task, which is determined by the student's preparedness scale at the level of probability of the correct answer P (  )  0. So the complexity of

In order to model the relations with access limitations we use a special type of oracle Turing machine (OTM) as follows: (1) the OTM, apart from the standard tape, has an oracle

This platform editorializes semantic enrichments carried out by the TRIPLE project by proposing the discovery of scientific issues in the fields of SSH by taking advantage of

For these sets of MDs a conjunctive query can be rewritten to retrieve, in polynomial time, the resolved answers, provided there are no joins on existentially quantified vari-

1, represent triple patterns and are responsible for routing partially matched copies of queries (referred to as query particles ) towards triple vertices that match the pattern of

A lay- out uses several HBase tables with different schemas to store RDF triples; each layout provides a tradeoff in terms of query performance/storage.. All operations on a RDF
