Medical ontologies are valuable and effective methods of representing medical knowledge. In this direction, they are much stronger than biomedical vocabularies. In the process of medical diagnosis, each disease has several symptoms associated with it. There are currently no ontologies that relate diseases and symptoms and only attempts at their infancy along with some simple proposed models. However,...
Today the channels for expressing opinions seem to increase daily. When these opinions are relevant to a company, they are important sources of business insight, whether they represent critical intelligence about a customer's defection risk, the impact of an influential reviewer on other people's purchase decisions, or early feedback on product releases, company news or competitors. Capturing and...
Welcome to the Seventh International Conference on Digital Information Management (ICDIM 2012). This year at Macau, after the previous editions in Bangalore (2006-India), Lyon (2007-France), London (2008-UK), Michigan (2009- USA), Lakehead (2010-Canada) and Melbourne (2011- Australia), we are pleased to host here at University of Macau that, in an impressive display of the international diversity...
This paper presents a layered approach to analysis and visualization of associations from events. The proposed approach provides different levels of abstraction for aggregating and analyzing events from heterogeneous data sources by using lists and customizable functions. Interfaces for creating lists and functions are also implemented for different levels of users. The effectiveness of the proposed...
In computer science, a computational challenge exists in finding a globally optimized solution from a tremendously large search space. Heuristic optimization methods have therefore been created that can search the very large spaces of candidate solutions. These methods have been extensively studied in the past, and progressively extended in order to suit a wide range of optimization problems. Researchers...
