Measuring Search Engine Quality

The effectiveness of twenty public search engines is evaluated using TREC-inspired methods and a set of 54 queries taken from real Web search logs. The World Wide Web is taken as the test collection and a combination of crawler and text retrieval system is evaluated. The engines are compared on a range of measures derivable from binary relevance judgments of the first seven live results returned. Statistical testing reveals a significant difference between engines and high intercorrelations between measures. Surprisingly, given the dynamic nature of the Web and the time elapsed, there is also a high correlation between results of this study and a previous study by Gordon and Pathak. For nearly all engines, there is a gradual decline in precision at increasing cutoff after some initial fluctuation. Performance of the engines as a group is found to be inferior to the group of participants in the TREC-8 Large Web task, although the best engines approach the median of those systems. Shortcomings of current Web search evaluation methodology are identified and recommendations are made for future improvements. In particular, the present study and its predecessors deal with queries which are assumed to derive from a need to find a selection of documents relevant to a topic. By contrast, real Web search reflects a range of other information need types which require different judging and different measures.

我国省级市体育局信息部门的组织构架

当前我国市级体育局的信息管理，还未独立地设置专门的部门，而把信息管理工作分散到原有的相关部门兼顾完成。这种现象与当前体育事业的发展不相适应。因此，建议在市级体育局的处级层面上，设置一个独立的信息管理部门，为体育局更好地利用信息和更及时地对信息作出反应提供更完善的服务。

Invisible children? The need for support groups for siblings of disabled children

Previous research and first-hand experience suggest that a child with a disability can have a profound effect on family life. Although the need for sibling support has been acknowledged in legislation, the implications for non-disabled siblings remain unclear. In this article, Angie Naylor, lecturer in psychology, and Phil Prescott, senior lecturer in childhood and youth studies, both based at Edge Hill, review a number of key themes emerging from the literature on sibling support. They go on to report the findings from an in-depth study of one sibling support group. The work was carried out in partnership with Barnardo's in the north-west of England and involved setting up a sibling support group, in response to an analysis of local need, and evaluating its impact. This research indicates a clear need for further service provision to meet the needs of the siblings of disabled children who attended the scheme. Angie Naylor and Phil Prescott argue for a reinvigorated debate about the needs of such children and champion the importance of listening to children and valuing what they have to say. The results of this small-scale evaluation project have clear implications for future research and, potentially, for policy and practice.
