Abstract: Multiquery optimization is performed in the context of RDF/SPARQL. Heuristic algorithms partition an input batch of queries into groups such that each group of queries can be optimized together. The optimization incorporates an efficient algorithm to discover the common substructures of multiple SPARQL queries and an effective cost model to compare candidate execution plans. No assumptions are made about the underlying SPARQL query engine. This provides portability across different RDF stores.

Abstract: Embodiments described herein are directed to providing local search engines over large databases. In one scenario, a computing system receives as inputs data records stored in a database. The computing parses the data records into file pairs that each include a keyword file and record ID file and merges file pairs into a keyword file and record ID file, where the keyword file includes keywords in sorted order, and where the record ID file includes a list of record IDs for keywords in the keyword file. The computing system further creates an offset file which stores offset values for starting addresses of record ID lists in the record ID file, and generates an index of keywords by assigning unique identifiers to keywords in the keyword file. The computing system also provides a query interface that allows the database's data records to be searched using the generated index of keywords.

Abstract: Keyword searching is used to explore and search large Resource Description Framework datasets having unknown or constantly changing structures. A succinct and effective summarization is built from the underlying resource description framework data. Given a keyword query, the summarization lends significant pruning powers to exploratory keyword searches and leads to much better efficiency compared to previous work. The summarization returns exact results and can be updated incrementally and efficiently.
