Policy learning for task-oriented dialogue systems via reinforcement learning techniques
Task-oriented dialogue systems such as Apple Siri and Microsoft Cortana are becoming increasingly popular and are attracting much attention. Task-oriented dialogue systems aim to serve people as virtual personal assistants. ...
Discrete optimization over graph problems
Discrete optimization problems are ubiquitous both in industry and theoretical computer science. They appear in a wide range of fields, such as manufacturing, planning, packing, design and scheduling. It is often the case ...
Protecting organizational knowledge: a strategic perspective framework
Organizational knowledge is considered a valuable resource for providing competitive advantage. Extensive research has been done on strategies to encourage knowledge creation and sharing. However, limited research has been ...
Supporting bodily communication in video consultations of physiotherapy
Physiotherapists are increasingly organising video consultations to support their patients over-a-distance. Physiotherapy is all about movements, and physiotherapists work on improving the subtle differences in the movements ...
Development and evaluation of a semantic-based access framework for health record linkage
Record linkage is the task of finding records in data sources that refer to the same entity across those different resources. In the health domain, record linkage is commonly used for identifying records belonging to the ...
Understanding how cloud computing enables business model innovation in start-up companies
Start-up companies contribute significantly to the national economies of many countries but their failure rate is notably high. Successful start-ups typically depend on innovative business models to be competitive and ...
Erasure codes for optimal performance in geographically distributed storage systems
The amount of digital data generated is overwhelmingly growing. Big data distributed storage systems will require a large storage backbone to store, process and analyse massive volumes of data. Such systems employ cheap ...
Investigating the evolution of structural variation in cancer
Cancers arise from single progenitor cells that acquire mutations, eventually dividing into mixed populations with distinct genotypes. These populations can be estimated by identifying common mutational profiles, using ...
Practical approximation algorithms for clustering and covering
The aim of this thesis is to provide solutions to computationally difficult network optimisation problems on modern architectures. There are three types of problem that we will be studying – clustering, covering and ordering ...
Real and misflagged duplicate question detection in community question-answering
Community question-answering (cQA) sites are websites that people visit to ask or answer questions. Some of these questions are asked repeatedly (although differently worded), resulting in a duplicate effort on the part ...
