Patent number: 10372736Abstract: 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 merge 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.Type: GrantFiled: May 16, 2014Date of Patent: August 6, 2019Assignee: University of Utah Research FoundationInventors: Feifei Li, Cody Hansen

Publication number: 20190005094Abstract: Systems are provided for processing of complex join queries. The systems receive a join query directed towards a set of tables. The systems randomly select an attribute from an index associated with a table from the set of tables. The selected attribute is selected based upon a query applied to the table. The systems identify a number of possible pathways from the selected attribute to a set of attributes in another table within the set of tables. Each pathway is representative of a possible join between the selected attribute and the attributes within the set of attributes. The systems then identify a terminating attribute within the set of tables. A contribution of the terminating attribute to a result is weighted by a number of possible pathways identified between an initial set of attributes and the terminating attribute.Type: ApplicationFiled: December 20, 2016Publication date: January 3, 2019Inventors: Ke Yi, Feifei Li

Patent number: 10095742Abstract: 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 sub-structures 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.Type: GrantFiled: November 28, 2016Date of Patent: October 9, 2018Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Songyun Duan, Anastasios Kementsietsidis, Wangchao Le, Feifei Li
