Text is not unadulterated fact. A text can make you laugh or cry but can it also make you short sell your stocks in company A and buy up options in company B? Research in the domain of finance strongly suggests that it can. Studies have shown that both the informational and affective aspects of news text affect the markets in profound ways, impacting on(More)
Bayesian Networks are probabilistic structured representations of domains which have been applied to monitoring and manipulating cause and effects for modelled systems as disparate as the weather, disease and mobile telecommunications networks. Although useful, Bayesian Networks are notoriously difficult to build accurately and efficiently which has(More)
Increasingly powerful fault management systems are required to ensure robustness and quality of service in today's networks. In this context, event correlation is of prime importance to extract meaningful information from the wealth of alarm data generated by the network. Existing sequential data mining techniques address the task of identifying possible(More)

The ongoing work presented in this paper is aimed at bringing self-configuration capabilities into next generation radio access networks. We present the main concepts and architecture of our prototype. We also introduce briefly a novel strategy for foreseeing the outcome of enforcing policies integrating behaviour discovery techniques and finite state(More)
BACKGROUND Hospital malnutrition is a significant problem that still remains under-recognised and under-treated in India. The present study assessed the effects of oral nutritional supplementation (ONS) in conjunction with dietary counselling versus dietary counselling (control) alone in malnourished patients when given in hospital and post-hospital(More)
The tremendous growth in ubiquity and diversity of wireless networks render the exploitation of highly heterogeneous next generation networks more challenging. This complexity is compounded by the highly dynamic nature of many of these network types and exacerbates the demands on the network management system to ensure robust service delivery. Various(More)
Policy-based network management (PBNM) is a promising but not yet delivering discipline aimed at automating network management decisions based on expert knowledge and strategic business objectives. One of the issues scarcely addressed in PBNM is the stability of the managed system as the result of the dynamic interaction between the ¿natural¿ network(More)
