Real-world information including subjective opinions and judgments need imprecise data to be modeled for representation and querying in databases. The Extensible Markup Language (XML) has become a de-facto standard for data modeling and exchange in recent years. Efforts on modeling imprecision and representing such data in XML have not been fully developed. In this paper, an XML based fuzzy data representation and querying system is presented. Complex and imprecise data are represented using a fuzzy extension of XML. The representation forms the basis for a system which enables fuzzy querying on XML documents using XQuery, a XML query language. The system also enables restructuring of XML Schemas through merging of elements of the XML documents. By using this feature of the system, application specific XML Schema and XML documents can be generated from the existing documents.


Fuzzy querying im XML databases
Üstünkaya, Ekin; Yazıcı, Adnan; Department of Computer Engineering (2004)
Real-world information containing subjective opinions and judgments has emerged the need to represent complex and imprecise data in databases. Additionally, the challenge of transferring information between databases whose data storage methods are not compatible has been an important research topic. Extensible Markup Language (XML) has the potential to meet these challenges since it has the ability to represent complex and imprecise data. In this thesis, an XML based fuzzy data representation and querying s...
HyGraph: a subgraph isomorphism algorithm for efficiently querying big graph databases
Asiler, Merve; Yazıcı, Adnan; George, Roy (2022-04-01)
The big graph database provides strong modeling capabilities and efficient querying for complex applications. Subgraph isomorphism which finds exact matches of a query graph in the database efficiently, is a challenging problem. Current subgraph isomorphism approaches mostly are based on the pruning strategy proposed by Ullmann. These techniques have two significant drawbacks- first, they are unable to efficiently handle complex queries, and second, their implementations need the large indexes that require ...
Prediction of Protein-Protein Interaction Relevance of Articles Using References
Calli, Cagatay (2009-09-16)
Classifying documents as protein-protein interaction (PPI) relevant or not is the first step towards extracting meaningful PPI data from article content. Currently, this classification step is handled manually by expert curators. A number of text-mining methods have been proposed to tackle this problem, using abstracts without references. We propose that article references contain important information that can be used to enhance these previous techniques. We trained an SVM classifier solely based on refere...
Secure logical schema and decomposition algorithm for proactive context dependent attribute based inference control
Turan, Ugur; Toroslu, İsmail Hakkı; Kantarcioglu, Murat (2017-09-01)
Inference problem has always been an important and challenging topic of data privacy in databases. In relational databases, the traditional solution to this problem was to define views on relational schemas to restrict the subset of attributes and operations available to the users in order to prevent unwanted inferences. This method is a form of decomposition strategy, which mainly concentrates on the granularity of the accessible fields to the users, to prevent sensitive information inference. Nowadays, du...
Flexible querying in an intelligent object-oriented database environment
Koyuncu, M; Yazıcı, Adnan; George, R (2000-10-28)
Many new-generation database applications demand intelligent information management necessitating efficient interactions between database gr. knowledge bases and the users. In this study we discuss evaluation of imprecise queries in an intelligent object-oriented database environment, IFOOD. A flexible query evaluation mechanism, capable of handling different data types including complex and imprecise data and knowledge is presented and key language issues are addressed.
