Semantic interoperability of the un/cefact ccts based electronic business document standards

Kabak, Yıldıray
The interoperability of the electronic documents exchanged in eBusiness applications is an important problem in industry. Currently, this problem is handled by the mapping experts who understand the meaning of every element in the involved document schemas and define the mappings among them which is a very costly and tedious process. In order to improve electronic document interoperability, the UN/CEFACT produced the Core Components Technical Specification (CCTS) which defines a common structure and semantic properties for document artifacts. However, at present, this document content information is available only through text-based search mechanisms and tools. In this thesis, the semantics of CCTS based business document standards is explicated through a formal, machine processable language as an ontology. In this way, it becomes possible to compute a harmonized ontology, which gives the similarities among document schema ontology classes of different document standards through both the semantic properties they share and the semantic equivalences established through reasoning. However, as expected, the harmonized ontology only helps discovering the similarities of structurally and semantically equivalent elements. In order to handle the structurally different but semantically similar document artifacts, heuristic rules are developed describing the possible ways of organizing simple document artifacts into compound artifacts as defined in the CCTS methodology. Finally, the equivalences discovered among document schema ontologies are used for the semi-automated generation of XSLT definitions for the translation of real-life document instances.


A metrics-based approach to the testing process and testability of object-oriented software systems
Yurga, Tolga; Doğru, Ali Hikmet; Department of Information Systems (2009)
This dissertation investigates the factors that affect testability and testing cost of object- oriented software systems. Developing a software program which eases the testing process by increasing testability is crucial. Also, to assess whether or not the testing effort and cost consumed or planned is adequate or not is another critical matter this dissertation aims to answer by composing a new way to evaluate the links between software design parameters and testing effort via source-based metrics. An auto...
Modular Verification of Asynchronous Service Interactions Using Behavioral Interfaces
Betin Can, Aysu; Bultan, Tevfik (2013-04-01)
A crucial problem in service oriented computing is the specification and analysis of interactions among multiple peers that communicate via messages. We propose a design pattern that enables the specification of behavioral interfaces acting as communication contracts between peers. This “peer controller pattern” provides a modular, assume-guarantee style verification strategy that consists of three phases. 1) Each individual peer is statically verified for conformance to its part of the contract, using soft...
Distributed Content Based Video Identification in Peer-to-Peer Networks: Requirements and Solutions
Koz, Alper; Lagendijk, R. (Inald) L. (2017-03-01)
In this paper, we first discuss the essential requirements for a fingerprint (perceptual hash)-based distributed video identification system in peer-to-peer (P2P) networks in comparison with traditional central database implementations of fingerprints. This discussion reveals that first, fingerprint sizes of existing video fingerprint methods are not compatible with the cache sizes of current P2P clients; second, fingerprint extraction durations during a query are not at tolerable levels for a user in the n...
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...
Design and implementation of a monitoring framework
Kuz, Kadir; Doğru, Ali Hikmet; Department of Computer Engineering (2009)
In this thesis work, the symptoms in Windows XP operating system for fault monitoring are investigated and a fault monitoring library is developed. A test GUI is implemented to examine this library. Performance tests including memory and CPU usage are done to see its overhead to the system and platform tests on the current version of Windows operating system series (Windows Vista) are done to see for compatibility. In this thesis, fault monitor-fault detector interface is also defined and implemented. To mo...
