Use Of Machine Learning Methods In Automatic Assessment Programming Assignments, Botond Tarcsay
Use Of Machine Learning Methods In Automatic Assessment Programming Assignments, Botond Tarcsay
Masters
Programming has become an important skill in today’s world and is taught widely both in traditional settings and online. Instructors need to assess increasing amounts of student work. Unit testing can contribute to the automation of the grading process; however, it cannot assess the structures, style and partially correct source code or differentiate between levels of achievement. The topic of this thesis is an investigation into the use of machine learning methods for assessing the correctness and quality of code, with the ultimate goal of assisting instructors in the grading process. In this research, we have used nine different machine …
Measuring Semantic Similarity Of Documents By Using Named Entity Recognition Methods, David Efraín Muñoz Morales
Measuring Semantic Similarity Of Documents By Using Named Entity Recognition Methods, David Efraín Muñoz Morales
Masters
The work presented in this thesis was born from the desire to map documents with similar semantic concepts between them. We decided to address this problem as a named entity recognition task, where we have identified key concepts in the texts we use, and we have categorized them. So, we can apply named entity recognition techniques and automatically recognize these key concepts inside other documents. However, we propose the use of a classification method based on the recognition of named entities or key phrases, where the method can detect similarities between key concepts of the texts to be analyzed, and …
Development Of A Workflow For The Comparison Of Classification Techniques, Zanifa Omary
Development Of A Workflow For The Comparison Of Classification Techniques, Zanifa Omary
Masters
As the interest in machine learning and data mining springs up, the problem of how to assess learning algorithms and compare classifiers become more pressing. This has been associated with the lack of comprehensive and complete workflow depending on the project scale to provide guidance to its users. This means the success or failure of the project can be highly dependent on the person or team carrying it. The standard practice adopted by many researchers and experimenters has been to follow steps or phases from existing workflows such as CRISP-DM, KDD and SASSEMMA. However, as machine learning and data mining …

Samats : Semi-Automated Modelling And Texturing System, Joe Hegarty
Masters
The creation of detailed 3D (three-dimensional) building models has become an area of considerable research over the last couple of decades. The accurate modelling of buildings offers LBS (Location Based Services) applications in planning, cultural heritage, tourism and e-commerce among others. The approach taken by the majority of contemporary modelling systems that use terrestrial imagery taken from arbitrary locations requires the user to carry out manual correspondences across the image set. These correspondences are used for two purposes. Firstly, the correspondences are used to determine the exterior orientation parameters (position and orientation) of the cameras used to capture each image. …
A Framework For Processing Viewer-Based Directional Queries In A Simulated Mobile Environment, Keith Gardiner
A Framework For Processing Viewer-Based Directional Queries In A Simulated Mobile Environment, Keith Gardiner
Masters
With the steady and fast advancements in the integration of geographic information systems and mobile location-based services, interest in exploiting this technology for Cultural Heritage (CH) data sharing has become apparent. In this area there has been an increasing need to integrate positional information with non-positional data and add a spatial dimension to the definition of a users “context” In this research the integration of Cultural Heritage information coupled with spatial technologies is investigated. The idea is based on a 3-tier architecture that positions the user at the client layer with a mobile device, a spatial query processor in the …
Development Of A Real-Time Digital Acquisition Software System For The Ocean Optics S1000 Spectrometer, Stephen Fennell
Development Of A Real-Time Digital Acquisition Software System For The Ocean Optics S1000 Spectrometer, Stephen Fennell
Masters
The objective of the M. Phil degree project was to improve the digital acquisition speed of the existing Ocean Optic I/O S1000 spectrometer system. Research carried out prior to this research work indicated that the existing system, although allowing for successful spectroscopic measurements, did not provide for a true time-base required for time-resolved spectroscopy. The analogue/digital speed aspects of the I/O were investigated and shortcomings were found in the digital I/O of the system. These shortcomings were investigated and the existing Ocean Optics software was found to have a considerable role in the lack of overall acquisition speed. Various Ocean …

Masters
Application of a differential pulse waveform to a microelectrode or a rotating disk electrode results in a peaked response for amperometric redox reactions. Based on these observations models were proposed and tested for these methods. Simulations of the models were carried out by inputting the relevant equations into Microsoft Excel. The microelectrode study revealed a good correlation between one model and the numerical derivative of the current following a linear sweep potential waveform. Experimentally the derivative can be obtained numerically following a linear sweep. The alternative differential pulse waveform requires more sophisticated equipment and the response can be affected by …
