Information Architecture is a part of Information Technology Architecture, and has attracted interest through e-business and e-government initiatives as well as through the general popularity of Service Oriented Architecture. In many ways there is nothing new about Information Technology Architecture; however both public and private sector organisations are becoming freshly receptive to talking about the strategic shaping of Information Technology using the language of Architecture. Information Architecture is a core responsibility of Information Technology management, and is as much organisational as technical, drawing on the breadth of the Information Systems field. This paper reviews the literature on Information Architecture to bring together a number of key issues within an overarching architectural perspective. It argues that its current topicality offers Information Systems practitioners a renewed opportunity and mandate to pursue an Information Architecture strategy, and offers academics a renewed incentive to research this area. 相似文献

The empirical import of Shannon's Information Theory and its impact on information science are discussed. It is argued that extension of the scope of Information Theory as well as development of new theories of information science presupposes better understanding of relevant empirical regularities and laws. Possibilities of broadening the empirical foundation of Information Theory by introduction of appropriate least effort criteria are discussed. 相似文献
