Integrating flexibility and fuzziness into a question driven query model

Abdullah Sarhan, Jon Rokne, Reda Alhajj
2018 Information Sciences  
Such interfaces range from visual to natural language based. This thesis contributes a question driven query model which falls under the natural language based category.  ...  Further, a relational database management system supports a structured query language (SQL) for data processing, and it is not possible to access and retrieve data from a relational database without knowing  ...  The ranges for these three fuzzy domains and their centroids are determined by analyzing the values present in the corresponding column which is intended to be queried based on a fuzzy term.  ...

Fuzzy queries in multimedia database systems

Ronald Fagin
1998 Proceedings of the seventeenth ACM SIGACT-SIGMOD-SIGART symposium on Principles of database systems - PODS '98  
These differences lead to interesting new issues, and in particular cause us to consider new typos of queries.  ...  This is in contrast to a rolationnl database, where the answer to a query is simply a set, In this paper, we survey some new issues that arise for multimedia queries, with a particular focus on recent  ...  Acknowledgments The author is grateful to Laura Haas, Jim Hafner, Wayne Niblack, Dragutin Petkovic, and Ed Wimmers for helpful comments and suggestions.  ...

Ranking-based processing of SQL queries

Hany Azzam, Thomas Roelleke, Sirvan Yahyaei
2011 Proceedings of the 20th ACM international conference on Information and knowledge management - CIKM '11  
The evaluation on the IMDB and Monster benchmarks proves that the PSQL-based approach is applicable to (semi-)structured and unstructured data and structured queries.  ...  The result is a general-purpose framework that can interpret any SQL query and then assign a probabilistic retrieval model to rank the results of that query.  ...  In other words, the structure of the data is not taken into consideration by the retrieval model and a bag-of-words representation is utilised (this is similar to the experimental methodology reported  ...

Domain specific multistage query language for medical document repositories

Aastha Madaan, Subhash Bhalla
2013 Proceedings of the VLDB Endowment  
This topic has not been sufficiently addressed by the existing approaches including SQL-like query languages or generalpurpose keyword-based search engines and document-level indexing based search.  ...  We aim to bridge the gap between information needs of the skilled/semi-skilled domain users and the query capability provided by the query language.  ...  For example, a physician has an exploratory evidence-based query 1 "cases where helicobacter pylon bacteria causes peptic ulcer" or he or she may have a hypothesis-directed query 2 , "Treatment in case  ...
