Existing approaches to e-mail filtering measure the likelihood of an e-mail spam based on the blacklist, whitelist, and the spaminess of the words in the content. However, false negative rates and false positive rates cannot be effectively improved without adopting new technologies. In this paper, we propose a social network analysis approach to e-mail filtering based on the previous communicat...

In a 50 people company we compared various performance metrics with social networking structure obtained by mining e-mail archives. We also calculated e-mail responsiveness and conducted an individual job satisfaction survey. We identified patterns of productive and less-productive e-mail usage. Results indicate that central network position reduces e-mail responsiveness, while this position in...

This paper presents the design and implementation of a system to summarize e-mail messages. The system exploits two aspects of e-mail, thread reply chains and commonly-found features, to generate summaries. The system uses existing software designed to summarize single text documents. Such software typically performs best on well-authored, formal documents. E-mail messages, however, are typical...

The purpose of the study is to examine how e-mail affects work performance. E-mail communication studies have aroused both praise and query regarding the suitability, appropriateness and effectiveness of electronic messages in information management. Less is known about the effects of e-mail on work performance. We consider (1) which e-mail features affect work performance; (2) whether these fe...

We investigate the use of decision forests for automated e-mail filing into folders and junk e-mail filtering. The experiments show that decision forests offer the following advantages: (i) ability to deal with the large dimensionality of feature vectors in text categorization, (ii) improved accuracy of the ensemble over the single decision trees and favourable comparison with a number of other...

Most e-mail readers spend a significant amount of time regularly deleting junk e-mail (spam) messages, which are a part of marketing campaigning efforts of various companies wherein users normally signed in and it also results in increasing volume of storage space and consumes network bandwidth. A challenge, therefore, rests with the developers and improvement of automatic classifiers that can ...

Secure environments protect the resources against unauthorized access by enforcing access control mechanisms. Therefore, when increasing security is an issue, text based passwords are not enough to counter such problems. Security has always been an issue since Internet and Web Development came into existence, numeric based passwords is not enough to counter such problems, which is also an out d...

This paper deals with practicability issues of encrypted e-mails. A quick survey on the status quo indicates that popular e-mail clients lack substantial practicability qualities, for example searching in encrypted e-mails. Other approaches such as De-Mail provide solutions, but offer transport encryption only. We present and discuss a number of improvements to the practicability of e-mail encr...

We study the topology of e-mail networks with e-mail addresses as nodes and e-mails as links using data from server log files. The resulting network exhibits a scale-free link distribution and pronounced small-world behavior, as observed in other social networks. These observations imply that the spreading of e-mail viruses is greatly facilitated in real e-mail networks compared to random archi...

The implementation of global virtual teams presents modern organizations with significant challenges, such as a multicultural workforce and the use of information and communication technology. Cultural diversity increases teamwork complexity and may weaken a team's effectiveness and jeopardize its viability. Selection and implementation of appropriate information technology may facilitate group...
