Conceptual queries using ConQuer-II [chapter]

A. C. Bloesch, T. A. Halpin
1997 Lecture Notes in Computer Science  
ConQuer-II's new features such as arbitrary correlation and subtyping enable it to be used for a wide range of advanced conceptual queries.  ...  While most conceptual query languages are based on the Entity-Relationship approach, ConQuer is based on Object-Role Modeling (ORM), which exposes semantic domains as conceptual object types, allowing  ...  Consequently, ActiveQuery's user interface was Conceptual Queries Using ConQuer-II 10 redesigned.  ...

2015 2015 IEEE 22nd International Conference on Software Analysis, Evolution, and Reengineering (SANER)  
Our initial empirical study on search tasks performed on the JavaScript/ECMAScript interpreter and compiler, Rhino, shows that the synonyms used to expand the queries help recommend good alternative queries  ...  Our approach also improves the precision and recall of Conquer, a state-of-the-art query expansion/reformulation technique, by 5% and 8% respectively. 978-1-4799-8469-5/15/$31.00 c 2015 IEEE SANER 2015  ...  II.

Query Formulation Technique Using of Data Web Mining

Mummoorthy Dr.A., Bhasker B., Karthik Deep Yadav S.J.
2018 Bonfring International Journal of Networking Technologies and Applications  
Query is the one of the search engine and arranges the data. To expose the bulk of data full the potential.  ...  We proposed one query fromatulation language called as MashQL it will be arrange the data on web and search the data.  ...  However, none of these approaches was used by casual users. This is because they still assume knowledge about the relational/conceptual schema.  ...

2007 Journal of the American Society for Information Science and Technology  
This framework is not only comprehensive and integrated, but also offers an explanation of the mechanisms governing the interaction between users' cognitive states and their manifested behavior when using  ...  in the change previous query, e.g., use plural forms Use a narrower To replace or add a term that is conceptually term lower or narrower in meaning than a term in the previous query Use a related To replace  ...  Research in IIS behavior has proposed a conceptual hierarchy to describe IIS behavior. First, user behavior can be viewed at different levels.  ...

The nautilus analyzer

Melanie Herschel, Hanno Eichelberger
2012 Proceedings of the 21st ACM international conference on Information and knowledge management - CIKM '12  
We thank the students having contributed to the visualization and annotation analyzer components as well as Adriane Chapman and Quoc Trung Tran to have shared their programs with us.  ...  Conceptually, we first consider a logical operator tree representation, the query tree, of the queries to be analyzed, e.g., of Q 1 .  ...  Each question is then processed using one or more of the implemented algorithms. These include Why-Not [1] , ConQuer [9] , Missing-Answers [7] , Artemis [5] , and lineage [3] 2 .  ...

ExConQuer: Lowering barriers to RDF and Linked Data re-use

Judie Attard, Fabrizio Orlandi, Sören Auer, Werner Kuhn
2018 Semantic Web Journal  
Through the ExConQuer Framework we provide a comprehensive set of tools that enable users to easily query linked datasets, download the results in a number of formats, and re-use previously-executed queries  ...  In order to help overcome this barrier, we propose the ExConQuer Framework (Explore, Convert, and Query Framework) as a tool that preserves the semantic richness of the data model while catering for simplified  ...  , legacy or domain-specific formats 4 , as well as (ii) to enable stakeolders to easily re-use persisted transformations.  ...

MapReduce Model using FPGA Acceleration for Chromosome Y Sequence Mapping

Asmaa G. Seliem, Hesham F. A. Hamed, Wael Abouelwafa
2021 IEEE Access  
The proposed algorithm uses D&C to divide the complete Y chromosome's length into (N*the size of the query sequence) and conquer each alignment process's results to get the final result.  ...  Divide and conquer is a robust algorithm for solving conceptually complex problems: all the technique requires is to divide an issue into sub-issues, which decreases the size of the case to be solved.  ...

An intelligent approach to handling imperfect information in concept-based natural language queries

Vesper Owei
2002 ACM Transactions on Information Systems  
Section 5 deals with semantically mismatched conceptual queries. Section 6 examines missing information in conceptual queries. Inexplicit conceptual queries are addressed in Section 7.  ...  Although these problems are widely studied in relational database systems, this is not the case in conceptual query systems.  ...  ConQuer-II allows queries to be formulated via paths through the conceptual schema. Query paths are constructed from the semantic roles of objects and entities.  ...

The dynamics of interactive information retrieval, Part II: An empirical study from the activity theory perspective

Yunjie Xu, Chengliang Liu
2007 Journal of the American Society for Information Science and Technology  
Users adopt a divide-and-conquer strategy in information retrieval. The planning of information retrieval activity is also partially manifested in query revision tactics.  ...  IIS research in other ways.  ...  Because users' subneeds are planned, and because query specification tactics steer queries through a corpus to satisfy subneeds, the use of tactics should also exhibit the divideand-conquer strategy.  ...
