A Content Management System (CMS) is a software application for creating, publishing, editing and managing content. The future step in content management system development is building intelligence over existing content resources that are heterogeneous in nature. Intelligence collected at the knowledge base can later on be used for executing semantic queries. Expressing the relations among content resources with ontological formalisms is therefore the key to implementing such semantic features. In this work, a methodology for the semantic lifting of JSR-170 compliant content repositories to ontologies is devised. The fact that in the worst case JSR-170 enforces no particular structural restrictions on the content model poses a technical challenge both for the initial build-up and further synchronization of the knowledge base. To address this problem, some recurring structural patterns in JSR-170 compliant content repositories are exploited. The value of the ontology extraction framework is assessed through a semantic search mechanism that is built on top of the extracted ontologies. The work in this thesis is complementary to the “Interactive Knowledge Stack for small to medium CMS/KMS providers (IKS)” project funded by the EC (FP7-ICT-2007-3).

Design and implementation of a privacy framework for web servicesin the travel domain Erkanar, Mehmet; Doğaç, Asuman; Department of Computer Engineering (2005) A web service is a collection of functions that are packaged as a single entity and published to the network for use by other programs. Web services are building blocks for creating open distributed systems, and allow companies and individuals to quickly and cheaply make their digital assets available worldwide. With considerable interoperability, privacy management becomes an inevitable concern of the web services. Companies and individuals should be able to restrict the information available about themsel...
Un/cefact ccts based e-business document design and customization environment for achivieng data interoperability Tunçer, Fulya; Doğaç, Asuman; Department of Computer Engineering (2009) The leading effort for creating a standard semantic basis for business documents to solve the electronic business document interoperability problem came from the UN/CEFACT (United Nations Centre for Trade Facilitation and Electronic Business) Core Components Technical Specification (CCTS) through a conceptual document modeling methodology. Currently, the main challenge in using UN/CEFACT CCTS based approaches is that the document artifacts are stored in spreadsheets and this makes it very difficult to disco...
An ontology-based multimedia information management system Tarakçı, Hilal; Çiçekli, Fehime Nihan; Department of Computer Engineering (2008) In order to manage the content of multimedia data, the content must be annotated. Although any user-defined annotation is acceptable, it is preferable if systems agree on the same annotation format. MPEG-7 is a widely accepted standard for multimedia content annotation. However, in MPEG-7, semantically identical metadata can be represented in multiple ways due to lack of precise semantics in its XML-based syntax. Unfortunately this prevents metadata interoperability. To overcome this problem, MPEG-7 standar...
An Automated defect detection approach for cosmic functional size measurement Yılmaz, Gökçen; Demirörs, Onur; Department of Information Systems (2012) Software size measurement provides a basis for software project management and plays an important role for its activities such as project management estimations, process benchmarking, and quality control. As size can be measured with functional size measurement (FSM) methods in the early phases of the software projects, functionality is one of the most frequently used metric. On the other hand, FSMs are being criticized by being subjective. The main aim of this thesis is increasing the accuracy of the measu...
A conformance and interoperability test suite for Turkey’s National Health Information System (NHIS) and an interactive test control and monitoring environment Sınacı, Ali Anıl; Doğaç, Asuman; Department of Computer Engineering (2009) Conformance to standards and interoperability is a major challenge of today`s applications in all domains. Several standards have been developed and some are still under development to address the various layers in the interoperability stack. Conformance and interoperability testing involves checking whether the applications conform to the standards so that they can interoperate with other conformant systems. Only through testing, correct information exchange among applications can be guaranteed. National H...
