With the explosive growth of data available on the Internet, discovery and analysis of useful information from web log data becomes a practical necessity. However, analysis of large web log files is a complex task not fully addressed by existing web access analyzers. Using commercial software, we applied data mining technology to analyze access log records collected on a web newspaper. We have ...

Using survey data from 240 US corporations we evaluate the use, satisfaction, and performance of forecasting software in practice. Despite large choices in commercial forecasting software packages only 10.8 percent of the respondents report using them. Most report using spreadsheets for forecast generation, and most software users routinely adjust software generated forecasts based upon their j...

Finite PMC surfaces have been analyzed with the help of a commercial software. The PMC effect is illustrated and the amplitude of successive evanescent waves is analyzed. It is found that the evanescent waves, as well as the effects of array truncation, are the strongest near the PMC. The evanescent waves may have a strong impact on the reactive component of antennas placed near the surface.

Exact inference is based on the conditional distribution of the sufficient statistics for the parameters of interest given the observed values for the remaining sufficient statistics. Exact inference for logistic regression can be problematic when data sets are large and the support of the conditional distribution cannot be represented in memory. Additionally, these methods are not widely imple...

One of the most intriguing ways that commercial developers of software can become more efficient is to reuse not only software but also best practices from the open-source movement. The open-source movement encompasses a wide collection of ideas, knowledge, techniques, and solutions. Commercial software vendors have an opportunity to both learn from the opensource community, as well as leverage...

This article presents an overview of selected general delivery options (e.g., videoconferencing, online learning, etc.) and specific software applications for developing and delivering instruction electronically, especially via the World Wide Web. A summary of the relative merits of developing customized software and of buying commercial software sets the stage for a brief review of 15 delivery...

This article describes an empirical study of the growth and evolution of three open source and three commercial software projects. This study identifies commonality and differences in the growth of these projects, and discusses how these results may be useful in planning software development strategies.

Present commercial software packages (such as ERP) have incorporated management insights, industry solutions, and best-practices to facilitate IT-business alignment. However, poor alignment of IT-business still exists on a large scale in practice. In this study, we investigate the notion of IT-business alignment from a managerial perspective and argue that, in addition to the four well-studied ...

Many commercial software firms face the possibility that free and open source software (FOSS) will disrupt their markets. A “disruptive innovation” is a new product, service, or business model that initially enters a market as a low-priced, lower-quality alternative to the products of market incumbents but which, through a process of rapid improvement, eventually satisfies mainstream consumers ...

This paper introduces the use of theVigilAgent agent methodology to develop monitoring systems. This work is based on the suitability of the specific characteristics of agency for developing monitoring systems. It is usual to develop them following an ad-hoc approach instead of using a methodology for achieving quality standards expected from commercial software. In this paper, the five phases ...
