A location-aware news feed system enables mobile users to share geotagged user-generated messages, e.g., a user can receive nearby messages that are the most relevant to her. In this paper, we present MobiFeed that is a framework designed for scheduling news feeds for mobile users. MobiFeed consists of three key functions, location prediction, relevance measure, and news feed scheduler. The loc...

In addressing the growing problem of junk E-mail on the Internet, we examine methods for the automated construction of filters to eliminate such unwanted messages from a user’s mail stream. By casting this problem in a decision theoretic framework, we are able to make use of probabilistic learning methods in conjunction with a notion of differential misclassification cost to produce filters Whi...

This paper describes the Natural Language Processing (NLP) component of an e-mail monitoring product called Assentor. Assentor monitors electronic correspondence for brokerage firms. It uses pattern-matching-based information extraction technology to find and quarantine e-mail messages that indicate, among others, customer complaints, insider trading, stock hyping, hard-pressure sales tactics,...

The paper proposes a non-parametric approach to filtering of unsolicited commercial e-mail messages, also known as spam. The email messages text is represented as an LSA vector, which is then fed into a kNN classifier. The method shows a high accuracy on a collection of recent personal email messages. Tests on the standard LINGSPAM collection achieve an accuracy of over 99.65%, which is an impr...

In this paper, a new e-mail management system is demonstrated in which all messages are prioritized. Each type of priority message is handled with a special method to enhance the efficiency of the proposed e-mail system. Also, a new management technique for user inbox is introduced. In addition, a minor upgrade in TCP (Transmission Control Protocol) message confirmation (ACK) is demonstrated, t...

One of the most popular Internet services is e-mail services which provide sending and receiving electronic messages of communication networks. E-mail standards and services apply various cryptographic algorithms to achieve the security goals (Stallings, 2006; Stallings, 2007) of confidentiality, integrity, authentication and non-repudiation. Data confidentiality in e-mail services is commonly ...

E-mail services are essential in the Internet. However, the current e-mail architecture presents problems that open it to several threats. Alternatives have been proposed to solve some problems related to e-mail services, offering reliability and scalability to such systems. This work presents a distributed trust model, allowing to create dynamic and decentralized trusted server lists, through ...

A significant amount of contribution to pragmatics research comes from cross-cultural and developmental pragmatic studies with L2 learners in focus; however, despite broad interest in such analyses, the role of lecturers has been relatively ignored. As the lectures’ perceptions/opinions of L2 learners’ e-mail requests are important, L2 learners must become familiar with their lecturers’...
