Embedding expert systems in semi-formal domains : examining the boundaries of the knowledge base

This thesis examines the use of expert systems in semi-formal domains. The research identifies the main problems with semi-formal domains and proposes and evaluates a number of different solutions to them. The thesis considers the traditional approach to developing expert systems, which sees domains as being formal, and notes that it continuously faces problems that result from informal features of the problem domain. To circumvent these difficulties experience or other subjective qualities are often used but they are not supported by the traditional approach to design. The thesis examines the formal approach and compares it with a semiformal approach to designing expert systems which is heavily influenced by the socio-technical view of information systems. From this basis it examines a number of problems that limit the construction and use of knowledge bases in semi-formal domains. These limitations arise from the nature of the problem being tackled, in particular problems of natural language communication and tacit knowledge and also from the character of computer technology and the role it plays. The thesis explores the possible mismatch between a human user and the machine and models the various types of confusion that arise. The thesis describes a number of practical solutions to overcome the problems identified. These solutions are implemented in an expert system shell (PESYS), developed as part of the research. The resulting solutions, based on non-linear documents and other software tools that open up the reasoning of the system, support users of expert systems in examining the boundaries of the knowledge base to help them avoid and overcome any confusion that has arisen. In this way users are encouraged to use their own skills and experiences in conjunction with an expert system to successfully exploit this technology in semi-formal domains

Opposition policies on identity cards

ID cards are a key point of difference between the main parties. Both the Liberal Democrats and the Conservatives have pledged to scrap them, while Labour will continue with their plans to introduce them. The LSE Identity Project has been following developments in the UK’s Identity Policy since the early days of the Identity Cards Bill in 2005. Here, Dr Edgar A. Whitley and Dr Gus Hosein from the LSE Identity Project analyse the Labour Party’s manifesto comment on identity cards

Challenges to ethical publishing in the digital era: a journal editor’s response to the limited mind reading skills of academic authors

Purpose – The purpose of this paper is to respond to Curno ' s article from the perspective of a journal editor. Design/methodology/approach – The paper is analysed and a commentary formulated. Findings – A tacit knowledge perspective is developed. Research limitations/implications – The perspective is of one editor of a journal published by Emerald. Originality/value – Given that the perspective is of a current editor, it provides a distinctive practical insight into some of the issues surrounding academic authorship. </jats:sec

The dynamic consent model provides a way forward for care.data

What do the delays to the care.data plans tell us about privacy and policy making? Edgar A. Whitley considers whether the delays are the result of a poor communication strategy, ill–advised nudges or the consequences of a particular view of respect for persons and individual autonomy

Experiments identify the challenges for the adoption of the open-standards services, argues Edgar Whitle

Submission to the House of Lords Constitution Committee Inquiry into "Legislative Process: Stage 1: Preparing legislation for introduction in Parliament" Consultation

Executive summary 1. This submission responds to a key section of the inquiry from the perspective of information systems: the social study of information and communications technologies. It focuses on the role of technology when addressing Questions 1–3 on creating a good law There are, however, also implications for Questions 6 and 7 (on the role of technology). 2. For questions 1–3, the submission draws on research that questions the idea of technology–neutral laws1 and argues instead that technological issues should not be left for codes of practice, regulations and statutory instruments. This because apparently neutral technological decisions can, in fact, have a significant impact on the way a law is implemented and, as such, should be subject to proper, detailed scrutiny. In particular, these decisions can be such a key part of the proposed legislation that they should be subject to more scrutiny than codes of practice and statutory instruments typically receive

How academic research has impact – but not always what the Minister wanted: the story of the LSE Identity Project

The last Labour government policy insisted that henceforward 25 per cent of all government aid to university R & D should be determined by how much ‘impact’ university research has on the economy and public policy. Academics from LSE’s ‘Identity Project’ have been heavily involved in the debates about the now scrapped government identity cards scheme. LSE published a critical report in 2005 only for some of the leading researchers to be singled out for attacks by Labour government ministers. Here Simon Davies, Edgar A. Whitley and Gus Hosein reflect on their experiences and discuss the perils for academic freedom in seeking to influence public policy. A more tolerant and broad-ranging consideration of university research can bring great benefits in building better policies from the outset

Scrapping costly and controversial proposals for identity cards
