OWL Formal Ontology for the Social Structure in the OperA Meta-model

In this thesis, we present the OWL OperA meta-model, which is redelivered from the OperA approach description into OWL2, and OWLperettA as a plug-in for OperettA to export the Social structure (SS) of an Organizational Model designed by OperettA into OWL2 format. The OWL OperA meta-model provides a more expressive way of defining or specifying...

Examining Mobile Search and Re-finding Behaviour

Mobile search has been a target of research for many years as it is challenging, multi-level and rapidly increasing in use, much like the mobile platforms themselves. This work examines the aforementioned subject from two of its aspects; mobile re-finding behaviour and queries' contextual information. Re-finding behaviour is an well-known...

Analyzing the Evolution of WSDL Interfaces using Metrics

Recent studies have investigated the use of source code metrics to predict the change- and defect-proneness of source code. While the indicative power of these metrics was validated for several systems, it has not been tested on Service-Oriented Architectures (SOA). In particular, the SOA paradigm prescribes the development of systems through...

Design of a coaching support system for evaluating sport tactics

Coaches are using video analysis to evaluate the performance of a team in field hockey. Events with the ball are tagged and saved in a match annotation file, which is used to lookup video fragments. The match annotation enables a coach to lookup and to evaluate single moments of the match but doesn't provide a coach insight in the tactic. Tactic...

Detection of Duplicate Content on Twitter

Depending on the needs of a user, searching on Twitter streams has proven to be very useful for a wide range of applications. Twitter however, has large volumes of information available in the form of tweets, that are shared by mil- lions of users. We have observed that many of these tweets contain mutually redundant information and due to this,...

Weak signal detection on twitter datasets: A non-accumulated approach for non-famous events

With the rise of social networking platforms, a great amount of data has been generated. Extracting information regarding interesting events from this large data pool has become an interesting direction of research. Multiple tools have been built for this challenge. Detecting the signals for a target event has thus become a crucial task and it...

Critical Success Factors for The Migration of Legacy Information Systems to SOA

Legacy Information Systems abbreviated as LIS are information systems that have been developed and deployed in the past and have been running critical business processes within an enterprise information system. Legacy Information Systems are considered the backbone of the organizations business since these systems are robust and carry valuable...

Methodology for Deploying Secure Applications in the Cloud

There are challenges that lie in migrating enterprise applications into the cloud .Certain enterprises might want data to be partly hosted on premise in the enterprise and also partly hosted in the cloud, while other enterprises might their applications to be fully hosted on the cloud. Such hybrid possibilities can enable enterprises to benefit...

Researching a transition to an organized chaos in enterprise system architectures

After its founding 15 years ago, Tam Tam has encountered the limits of legacy systems used for the internal processes in recent years. To overcome these limits, multiple efforts have been made to enforce a transition to specific Enterprise Application Integration styles. Although the efforts resulted in working application interactions, the...

Exploiting Twitter to fulfill information needs during incidents

How can Twitter be exploited to fulfill information needs of users on Twitter during incidents? In this Thesis this question wil be investigated and a strategy to locate tweets which fulfill information needs will be introduced. First, techniques are proposed to automatically detect incidents given an unstructured incident data source and...

Tag-based Recommender System

Organizers of STRP Art and Technology Festival want to enhance the festival experience of visitors whilst also learning more about these visitors. The proposed solution is a tag-based recommender system, where the feedback received from visitors will allow STRP to learn more about how visitors perceive art pieces and in turn provide visitors...

Model-driven Generation of Semantic Web Applications

An increasing amount of datasets that can be combined with other datasets is emerging. Particularly the SemanticWeb allows creating links between datasets, which increase the value of the dataset that is being linked. Finding links between datasets, as well as capturing the data inside another dataset that is of interest is a process for which...

Supporting the Tennis Coach: Automatically Analyzing and Evaluating Tennis Footage

Video support is becoming an indispensable tool in tennis practice sessions, especially at the professional level. Cameras are used to record a player and the current available software is used optimize the player's tennis technique, i.e. the biomechanics. Unfortunately, the tactical side of tennis is underexposed in terms of available software....

A Semantic Web based approach to expertise finding at KPMG

An important requirement for realizing high organizational effectiveness within large organizations is the existence of an expertise finding application which enables rapid discovery of expertise inside the organization. The main goal of this research was to investigate how Semantic Web techniques could be used to increase the findability and...

Designing Linked Data Applications

A lot of (legacy) datasets can be combined with other datasets in order to increase their value. New technologies and ideas around the Semantic Web are evolving to make these enrichments possible. In recent years, the Linked Data principles have become the established standard for publishing data on the Semantic Web. With these techniques and...

BibMix: Enrichment of Citation Metadata Based on Integration of Bibliographic Data

A citation in an academic text provides the reader with exact publication information to uniquely identify and locate a scholarly resource for further study. In the domain of academic research, citations are a key part of linking discrete pieces of knowledge. As opposed to the natural language mostly used in academic texts, bibliographic...

Evaluating the State-of-the-Art in Business Process Management Tools and Methodologies

Although people have tried to control processes for centuries, with the more recent introduction of larger economies-of-scale and the toughening economic environment organisations are increasingly interested in improving their business processes. This has resulted in the emergence of Business Process Management (BPM), a field that has quickly...

Round-trip Business Process Driven SOA modelling between ARIS and Cordys

Business process modelling is the core activity in Business Process Driven SOA. ARIS is as Business Process Analysis (BPA) tool adequate for analyzing and designing business processes, while the execution and monitoring of these processes is empowered by Cordys as Business Process Management Suite (BPMS). The challenge is to enable iterative...
