Small-world phenomena were initially studied in the 1960s through a series of social network experiments, and are, as evidenced by the game “The six degrees of Kevin Bacon,” even part of our pop-culture. Recently, mathematicians and physicists have shown that most small-world phenomena are expected consequences of the mathematical properties of certain networks– known as small-world networks. I...

Bereits seit 2007 sind die Mitarbeiter weltweit vernetzt. Der enorme Erfolg von Internetplattformen wie Facebook oder XING hat unter anderem dazu geführt, dass die ursprünglich primär für private Zwecke konzipierten Social Networking Services (SNS) in den vergangenen Jahren auch für Unternehmen zunehmend interessanter wurden. Dementsprechend ver suchen aktuell bereits einige Organisationen die ...

a r t i c l e i n f o In this article, the author examines voluntary self-disclosure phenomenon among social networking sites. Self-disclosure enables member interactions, service customizations, targeted marketing, and digital content generation; hence the level of self-disclosure is imperative to the success of social networking sites. Yet, members are often reluctant to reveal themselves des...

The social computing, such as social networking services (SNSs) and social Networking Platforms (SNPs) provide a coherent medium through which people can be interactive and socialize. The SNP is a Web-based social space, specifically designed for end user-driven applications that facilitate communication, collaboration and sharing of the knowledge through a variety of SNSs, such as text, video ...

Social networking services (SNSs) have recently emerged as a research topic of interest, in line with their commercial success and popularity. They are internet (sometimes mobile) services that have, as a primary purpose, the building and sustaining of users’ social networks. In this article we conduct two analyses. We review the existing literature on social networking software, and we examine...

Social Networking Sites (SNS) have become a key component of users’ experience of the internet. Whilst much has been made of the social dynamics of online SNS, the influence of the structures and operations of these sites – and the business models behind them – on users is rarely accounted for. This paper argues that behind the social behaviours supported by SNS, there is a growing shift toward...

Sentient computing was conceived in 1999 and aims to make applications more responsive and useful by observing and reacting to the physical world [7]. It is particularly attractive in a world of mobile users and computers. In recent years we have observed a convergence between services enabled by ubiquitous computing technologies [16] and applications offered to social networks. The overlap wil...

This article aims at summarizing existing methods for sampling social networking services and proposing a faster confidence interval for related sampling methods. Social networking services (SNSs), such as Facebook and Twitter, are an important part of the current Internet culture. Collecting samples from these networks, therefore, is necessary for learning more about sociological or cultural i...

A good friend of mine died recently after a sudden and brief illness. One of the things that helped those of us who cared for and about her was the use of the social networking Web site, LotsaHelpingHands (www.lotsahelpinghands.com). The site enabled us to provide updates to her family and friends near and far, receive messages from them, coordinate her care, and help the family with food and c...

Nahezu jede Woche geht mittlerweile ein neuer Social-NetworkingDienst online und allgemein lässt sich feststellen, dass Nutzungshäufigkeit und Nutzungsumfang von Diensten zum privaten Social-Networking sehr stark zugenommen haben. Neben der privaten Nutzung stehen solche Anwendungen inzwischen auch für die Nutzung in und um Unternehmen zur Verfügung, v.a. um den Austausch impliziten Wissens zu ...
