Deal sites are widely used for some time and there is a growing body of knowledge on them. There exists literature on infomediaries. But there is a gap when it comes to infomediaties focused on deal sites, i.e. aggregators of deal site offers. The research focused on impact of Big Five Inventory personality traits on whether respondents prefer visiting individual deal sites, or aggregators, or ...

This paper examines the development of web aggregators, entities that collect information from a wide range of sources, with or without prior arrangements, and add value through post-aggregation services. New Web-page extraction tools, context sensitive mediators, and agent technologies have greatly reduced the barriers to constructing aggregators. We predict that aggregators will soon emerge i...

Many decades of research have produced a significant amount of data showing increased oxidative stress in asthma and indicating a potential role for oxidants in the pathogenesis of the disease, particularly during exacerbations. Putatively relevant pro-oxidative mechanisms have also been identified. Currently available asthma drugs are generally effective for the treatment of the disease, but t...

In this study, we investigate the review system of Amazon.com, which is regarded as one of the most successful e-commerce websites in the world. We believe that the review results provided by Amazon’s review system may not be representative of the advertised products because the system does not consider two essential factors, namely the credibility and the time-decay of public reviews. Using a ...

FNR can detect various sentiments of news articles, and determine the sentimetal preferences of a user based on the sentiments of previously read articles by the user. While there are many news portal sites o...

After has been delivered DSO, it needs settled. This is typically done by comparing load measurements with a baseline. baseline describes an asset’s power profile in case no would have delivered. Until recently, baselining ...

We present a novel methodology for identifying public knowledge and eliminating the biases it creates when aggregating information in small group settings. A two-stage mechanism consisting of an information market and a coordination game is used to reveal and adjust for individuals’ public information. A nonlinear aggregation of their decisions then allows for the calculation of the probability...

A High Yield Investment Program (HYIP) is an online Ponzi scheme, a financial fraud that pays outrageous levels of interest using money from new investors. We call this fraud ‘postmodern’ in that sophisticated investors understand the fraud, but hope to profit by joining early. These investors support ‘aggregators’ – reputation websites that track the status of HYIPs. We examine 9 months of agg...
