Query recommendation using query logs in search engines
TL;DR: A method is proposed that, given a query submitted to a search engine, suggests a list of related queries that are based in previously issued queries and can be issued by the user to the search engine to tune or redirect the search process.
Proceedings ArticleDOI
Foundations of semantic web databases
TL;DR: This work proposes a query language with well-defined semantics and study the complexity of query processing, query containment, and simplification of answers, including computational aspects of testing entailment and redundancy.
Book ChapterDOI
Temporal RDF
TL;DR: In this paper, the authors present a framework to incorporate temporal reasoning into RDF, yielding temporal RDF graphs, and a syntax to incorporate temporality into standard RDF graph.
Journal ArticleDOI
Capturing summarizability with integrity constraints in OLAP
TL;DR: A sound and complete algorithm for solving the implication of dimension constraints that uses heuristics based on the structure of the dimension and the constraints to speed up its execution is given.
Book ChapterDOI
Query relaxation in RDF
TL;DR: Flexible querying of RDF data is explored, with the aim of making it possible to return data satisfying query conditions with varying degrees of exactness, and to rank the results of a query depending on how "closely" they satisfy the query conditions.
