Bei abriss aufstand de4/9/2023 This high precision was reached using a combination of trained n-grams, structural properties (e.g. Our experiments show a maximal accuracy of 83.5% overall. We present a set of 80 features and extensively experiment with possible combinations and SVM parameters to identify the best constellation for the categorization into the four different web genres. Especially the new distinction between news portals and blogs allows analyses to adapt to the network-specific characteristics of traditional media with high journalistic effort and more personal weblogs and their authors. In this research, we focus on the distinction between traditional blogs, news portals, forums and miscellaneous websites. Due to the increasing diversity of blog usage, the initial categorization into web genres is the first necessary step before any analyses. Hence researchers and industry have interest in analyzing the blogosphere. In recent years, blogs have become a very popular way to publish information, express opinions and hold discussions. By evaluating the metric with a test data set of 12,000 crawled blogs, we demonstrate the plausibility of our approach. We divide the consistency ranking in four different aspects: (1) intra-post, (2) inter-post, (3) intra-blog, and (4) inter-blog consistency. to separate them from the mass of blogs that report on random topics, we introduce a metric for blogs based on topic consistency. To ease the retrieval of expert blogs, i.e. To find these blogs is particular important for other domain experts to identify blogs that they would like to follow and stay in active contact. how focused an author reports on a single topic, is a sign for expert knowledge. We argue that the consistency of a blog, i.e. This results in a low ranking from today's blog retrieval systems. On the other side, niche blogs with a very specific topic only attract a small audience and thus have only a small reach. Current ranking algorithms, such as PageRank, Technorati authority, and BI-Impact, favor blogs that report on a diversity of topics since those attract a large audience and thus more visitors, links, and comments.
