Improving cardiac patients' medication compliance is a major factor in reducing mortality rate and reducing hospitalization rate. This paper describes a novel medication compliance management system. Its novelty lies in the combination of functionalities that helps the patient to comply with their medication regimen, together with a personal health monitoring system that monitors their health and collects vital signs data using a mobile phone and wireless bio sensors. The system is designed to collect and analyse medication compliance, side effects and symptom responses and transfers the collected data in real time to a web based system for remote monitoring by caregivers and health professionals. Health professionals can use the system to assess the effect of the medication regimen on their patients' health and adapt it to reduce side effects and maximise the patient's wellbeing.

The huge increase in online content has rapidly stepped up the challenges facing various entities such as organisations, businesses, governments. Dealing with this immense increase in information is beyond any human ability, as it requires massive efforts to go through huge volumes of posts/news to analyse and understand their content. In responding to this challenge, research has picked up in recent years to automatically analyse, and extract opinions/sentiment from online content. This thesis investigated the area of sentiment analysis and its impact on financial market entities. The thesis includes a review of the sentiment analysis processes, , an overview of sentiment analysis studies and their application to the financial markets domain. The literature shows a gap in defining systematic and reusable evaluation processes, for users to automatically conduct impact analysis of sentiment datasets in different financial contexts. In addressing the research gap the thesis proposes a framework called News Sentiment Impact Analysis (NSIA) which consists of three components which are a conceptual data model, a software architecture, and a set of use cases. The key component which is the conceptual data model captures three sets of parameters: the financial context parameters, the sentiment related parameters, and the impact measure parameters. The CPD model is supported by a software architecture, which consists of a GUI, Business, and Data layers. The main use case allows the analyst to define the CPD parameters using the provided GUI layer and trigger the impact analysis process. To evaluate the proposed framework, a prototype is implemented. Three case studies have been conducted to evaluate the different aspects of the proposed framework.
