Data Mining for Web Site Evaluation

Abstract

This paper evaluates the actual use of a course Website by graduate social work students. The study utilized data mining techniques to discover meaningful trends by using the data from server logs. The course Website was accessed 24,730 times by all 49 graduate students during a semester. The students utilized the course Website 23 hours a day, 7 days a week, day and night, evening hours, and weekends. The most popular area was the course documents area and the least popular was the student area. Study findings have implications for distance learning in higher education.     

HTML5本地数据存储技术研究

随着互联网信息量的迅猛增长,以及B/S架构的应用逐步深入,服务器端存储数据的压力越来越大,传统的Cookies方式已显得力不从心.HTML5通过两种方式:Web Storage和Web SQL Database将一些数据存储在本地客户机,避免了服务器存储容量和网络传送带宽的限制,同时也可以存储较大容量的数据,从而支持网络应用程序的推广和应用.

Cascading the use of Web 2.0 technology in secondary schools in the United Kingdom: identifying the barriers beyond pre-service training

This paper reports on research that took place at two universities in the United Kingdom, over two years. The research focuses on the use of Web 2.0 technology, specifically blogs, with pre-service teachers, both during their university programme and the first year of teaching as full-time newly qualified teachers (NQTs). The purpose of this research was to add to a developing body of knowledge by identifying whether technology used by pre-service teachers during their training course can be cascaded into their practice once qualified. Key findings identify a number of enablers and barriers to cascading technology in the classroom; these include curriculum time, pupil skills and support. The research concludes that early professional support and development should continue during the early years of teaching and assumptions about new teachers as champions of cascading innovative use of Web 2.0 technologies into their practice as NQTs may be over-optimistic.     

Website usage metrics: A re-assessment of session data

Metrics derived from user visits or sessions provide a means of evaluating Websites and an important insight into online information seeking behaviour, the most important of them being the duration of sessions and the number of pages viewed in a session, a possible busyness indicator. However, the identification of session (termed often ‘sessionization’) is fraught with difficulty in that there is no way of determining from a transactional log file that a user has ended their session. No one logs out. Instead a session delimiter has to be applied and this is typically done on the basis of a standard period of inactivity. To date researchers have discussed the issue of a time out delimiter in terms of a single value and if a page view time exceeds the cut-off value the session is deemed to have ended. This approach assumes that page view time is a single distribution and that the cut-off value is one point on that distribution. The authors however argue that page time distribution is composed of a number of quite separate view time distributions because of the marked differences in view times between pages (abstract, contents page, full text). This implies that a number of timeout delimiters should be applied. Employing data from a study of the OhioLINK digital journal library, the authors demonstrate how the setting of a time out delimiter impacts on the estimate of page view time and the number of estimated session. Furthermore, they also show how a number of timeout delimiters might apply and they argue that this gives a better and more robust estimate of the number of sessions, session time and page view time compared to an application of a single timeout delimiter.

Mathematical models for academic webs: Linear relationship or non-linear power law?

Previous studies of academic web interlinking have tended to hypothesise that the relationship between the research of a university and links to or from its web site should follow a linear trend, yet the typical distribution of web data, in general, seems to be a non-linear power law. This paper assesses whether a linear trend or a power law is the most appropriate method with which to model the relationship between research and web site size or outlinks. Following linear regression, analysis of the confidence intervals for the logarithmic graphs, and analysis of the outliers, the results suggest that a linear trend is more appropriate than a non-linear power law.
