To address this challenging issue, this paper proposes a project-based KM system that helps to acquire and trans...

We allow bloggers to differ along two dimensions: (1) the ability to post news-breaking content, and (2) the ability to find news in other blogs. By linking, a blog signals to the reader that it wi...

While these studies have provided important insights into the content of A-list political blogs (Adamic and Glance, 2005), how A-list political blogs influence media coverage (Drezner and Farrell, 2004) and who A-list political bloggers are (McKenna and Pole, 2004), they have largely ignored t...
