Models to Combat Email Spam Botnets and Unwanted Phone Calls

Husna, Husain 05 1900 (has links)
With the amount of email spam received these days it is hard to imagine that spammers act individually. Nowadays, most of the spam emails have been sent from a collection of compromised machines controlled by some spammers. These compromised computers are often called bots, using which the spammers can send massive volume of spam within a short period of time. The motivation of this work is to understand and analyze the behavior of spammers through a large collection of spam mails. My research examined a the data set collected over a 2.5-year period and developed an algorithm which would give the botnet features and then classify them into various groups. Principal component analysis was used to study the association patterns of group of spammers and the individual behavior of a spammer in a given domain. This is based on the features which capture maximum variance of information we have clustered. Presence information is a growing tool towards more efficient communication and providing new services and features within a business setting and much more. The main contribution in my thesis is to propose the willingness estimator that can estimate the callee's willingness without his/her involvement, the model estimates willingness level based on call history. Finally, the accuracy of the proposed willingness estimator is validated with the actual call logs.

Gespräche in einer Krise : Analyse von Telefonaten mit einem RAF-Mitglied während der Okkupation der westdeutschen Botschaft in Stockholm 1975 / Conversations in a crisis : Analysis of telephone communication with a member of the red army faction during the 1975 occupation of the West German embassy in Stockholm

von der Heiden, Gregor January 2009 (has links)
When crises develop, people are confronted with difficulties beyond those experienced in normal everyday activities.  Due to the perceived threats inherent to such situations, familiar behaviors may prove ineffective, and such attempts can pose dangerous and unpredictable risks. Crises are extreme situations, occurring at the very edges of human experience. Oral communication in such situations cannot be casual; the seriousness of the situation demands exceptional communicative performance on the part of the participants. Therefore, certainties about everyday communication conventions are called into question. The following work examines conversations during which the participants were involved in an extreme situation. In this particular crisis, a politically motivated kidnapping, the personal involvement of the interlocutors is substantial. A clear and present fear of the situation escalating and the possibility of a failure to anticipate the resulting reactions from the other party(ies) characterize the communicative acts of those involved. Recorded telephone calls during the occupation of the West German Embassy in Stockholm by members of the Red Army Faction (RAF) on April 24, 1975 comprise the basis for this analysis. One of the occupiers speaks with various interlocutors located in an adjacent embassy building. These interlocutors are relatives of the hostages, the Swedish Minister of Justice, and a German official charged with leading the negotiations. In this study, the communicative processes of the crisis are reconstructed. In order to show how the interlocutors attempt to reach their goals in this tense situation with the resources available to them, as well as what they in fact achieve, ethnographic methods of analysis have been employed. This study shows how, despite strong conflicting interests and motives, a shared reality is built through the actions of the interlocutors. The interaction between two key figures in the early stages of the crisis can even be characterized as a form of coalition building. An explanation as to why this collaboration is not retained in the subsequent course of the events, however, leading to an escalation of the situation, is also presented. Furthermore, the following work sets forth qualities needed to interactively build a coalition in a precarious crisis situation, which has arisen between parties characterized by diametrically opposed aims.

Dès lors, les éléments de base du schéma de la communication ont été posés et les particularités de notre corpus explicitées à la suite d’un double choix :celui des outils d’analyse réellement utiles à la démarche et celui des éléments essentiels et nécessaires constitutifs des énoncés retenus et à retenir.<p><p>L’énonciation et l’énoncé<p>Le travail porte sur l’analyse d’un certain type de discours à l’intérieur d’actes de communication sur base d’énoncés, produits d’un acte d'énonciation, qui comportent des marques énonciatives faisant référence à la fois au locuteur et à l'allocutaire. <p>Il en est tenu compte lors de la description du corpus car les éléments retenus portent non seulement sur la structuration phrastique de l’énoncé mais également sur le sens qui lui est donné ainsi que ses utilisations caractéristiques en fonction des intentions, choix et motivations des destinateurs.<p><p>Le sens et le son<p>La considération du langage sous sa double articulation favorise une analyse appariant les points de vue sémantique et phonologique :le sens et le son.<p>\ / Doctorat en philosophie et lettres, Orientation linguistique / info:eu-repo/semantics/nonPublished
