Selectivity estimation for hybrid queries over text-rich data graphs
2013
Proceedings of the 16th International Conference on Extending Database Technology - EDBT '13
Preserved Fulltext
With this general probabilistic solution, BN + , selectivity estimations can be obtained for queries over text-rich graph-structured data, which may contain structured and string predicates (hybrid queries ...
In this work, we propose a template-based probabilistic model, which enables selectivity estimation for general graph-structured data. ...
Towards a holistic solution for selectivity estimation of queries over text-rich data graphs, we provide the following contributions: (1) for our work we rely on an instantiation of a general template-based ...

Text-rich RDF data is frequently queried via predicates matching structured data, combined with string predicates for textual constraints (hybrid queries). ...
Evaluating hybrid queries efficiently requires means for selectivity estimation. ...
Such text-rich RDF descriptions are often queried with queries, which comprise predicates that match structured data as well as words in text data (hybrid queries). ...

To alleviate this problem, we present a hybrid approach that blends several language modelling techniques for question retrieval, namely, the classic (query-likelihood) language model, the state-ofthe-art ...
However, as the text of each question is short, there is usually a lexical gap between the queried question and the past questions. ...
