WEB PAGES, AUTHORS AND AUDIENCES: The meaning of a mouse click

One popular framework for analysing web pages has been to think of them as identity performances on the part of the author. This framework opens up possibilities for analysis of the ways in which identity performances are composed. The personal web pages to which this perspective is most immediately applicable, are, however, now only a small proportion of the overall amount of information available on the World Wide Web. It would be possible, by extension, to analyse institutional web pages as performances of the institutional identity. It is the contention of this paper that to do so is to miss out on some important aspects of web page design: namely that the production of a web page involves understandings not only of the audience for the page but also of the capacities of the technology. In addition, web page production has to become a socially meaningful act for the individual web page developer and the institution concerned. It is, therefore, argued that the analysis of web pages can usefully learn from media studies and the sociology of technology in this respect. An interview-based study of the developers of web pages for the service departments of a UK university is described. The ideas of audience which the authors use are far from homogeneous: they include an institutional offline audience for the page, a pre-existing imagined audience, developers themselves as audience, and the technology of the browser as a stand-in audience. The audience and the capacities of the technology are developed in context through the practices of designers.     

基于滑动窗口的自适应网页预测模型

PPM模型广泛应用于Web预取技术,但大多数的PPM模型不具有自适应性,不能反映用户浏览模式的改变。通过对标准PPM模型的扩展,提出基于滑动窗口的自适应网页预测模型。该模型仅保留处于滑动窗口之内的最近访问序列,从而反映用户兴趣的变化,同时利用非压缩后缀树增量式添加新的用户请求和删除过时的浏览信息,以提高更新速度。实验表明,该模型能更准确地描述用户在Web上的浏览特征,在预取性能上明显地优于以往的模型。

Target detection from a classical and a Bayesian viewpoint

Two approaches have been used for designing spatial surveys to detect a target. The classical approach controls the probability of missing a target that exists; a Bayesian approach controls the probability that a target exists given that none was seen. In both cases, information about the likely size of the target can reduce sampling requirements. In this paper, previous results are summarized and then used to assess the risk that Roman remains could be present at sites scheduled for development in Greater London.
