In this paper we present an approach for identifying network anomalies by visualizing network flow data which is stored in weblogs. Various clustering techniques can be used to identify different anomalies in the network. Here, we present a new approach based on simple K-Means for analyzing network flow data using different attributes like IP address, Protocol, Port number etc. to detect anomal...

In this paper we compare our selection based learning algorithm with the reinforcement learning algorithm in Web crawlers. The task of the crawlers is to find new information on the Web. We performed simulations based on data collected from the Web. The collected portion of the Web is typical and exhibits scale-free small world (SFSW) structure. We have found that on this SFSW, the weblog updat...

Many approaches to Weblog analysis draw on words found in the postings and comments, and the meaning of those words is inherently bound to a language. Moving beyond single-language analysis will require tools that leverage translation resources in ways that are well matched to the task. In this paper, we describe how state of the art techniques developed originally for machine translation and c...

This paper deals with the relationship between weblog content and time. With the proposed temporal mutual information, we analyze the collocations in time dimension, and the interesting collocations related to special events. The temporal mutual information is employed to observe the strength of term-to-term associations over time. An event detection algorithm identifies the collocations that m...

In diesem Beitrag soll am Beispiel der Ringvorlesung „Umgang mit Heterogenität in der Schule“ dargestellt werden, wie Blogs in Großveranstaltungen (Vorlesungen mit mehr als 250 Teilnehmenden) erfolgreich eingesetzt werden können, um die Aktivität und Interaktion der Studierenden zu fördern sowie Lernprozesse zu initiieren. Im Mittelpunkt steht dabei das zur technischen Unterstützung des didakti...

Das 2009 gestartete Weblog Sags uns (www.tu-braunschweig.de/sagsuns) der TU Braunschweig versucht, Ideen, Lob, Kritik und Beschwerden aller Studentinnen und Studenten, Mitarbeiterinnen und Mitarbeiter der Universität auf einer InternetPlattform zentral zu bündeln. Alle Beteiligten können mitschreiben, diskutieren und gemeinsam Verbesserungen für Studium und Lehre an der TU Braunschweig initiier...
