This is the 12th article in a series highlighting the case studies of DSM Task XV, Network Driven DSM. This Task demonstrated that DSM can be successfully used to support electricity networks in two main ways 1) by relieving constraints on distribution and/ or transmission networks at lower costs than building ‘poles and wires’ solutions, and 2) by providing services for electricity network sys...

Arguably one of the most important features of Twitter is the support for“retweets”or messages re-posted verbatim by a user that were originated by someone else. (This does not include modified tweets that sometimes are referred to as retweets.) Despite the fact that retweets are routinely studied and reported, many important questions remain about user motivation for their use and their signif...

In the context of a national election, this study explores more than 69,000 Twitter messages containing mentions of political parties and about 2,500 related user profiles to investigate the network structure of political microbloggers with respect to, first, their party preference and, second, the topics they discuss. We find that political microbloggers tend to follow like-minded peers. Micro...

The social web is characterized by a wide variety of connections between individuals and entities. A challenge for recommendation is to represent and synthesize all useful aspects of a user’s profile. Typically, researchers focus on a limited set of relations (for example, person to person ties for user recommendation or annotations in social tagging recommendation). In this paper, we present a...

One of the conditions for the successful introduction of ICT-based homecare services is to allow non-technical persons such as home nurses to personalize these services. We refer to this process of homecare service personalization as service tailoring. Service tailoring can be done by configuring and composing previously developed and deployed service building blocks. In this paper, we describe...

Our aim is to develop methodology for recognition of Internet portal users on the base of their browsing patterns. This is a classification task in which we have thousands values of decision attribute and objects are described by means of sequences of symbols. We develop feature selectors which make our task tractable. Since the behaviour usually does not distinguish users, we introduce user pr...

Current online public opinion analysis systems can explore lots of hot events and present the public emotion distribution for each event, which are useful for the governments and companies. However, the public emotion distributions are just the shallow analysis of the hot events, more and more people want to know the hidden causation behind the emotion distributions. Thus, this paper presents a...

The notion of profile appeared in the 1970s decade, which was mainly due to the need to create custom applications that could be adapted to the user. In what follows, we treat the different aspects of the user’s profile, defining it, profile, its features and its indicators of interest, and then we describe the different approaches of modelling and acquiring the user’s interests.

The evolution of 3rd generation mobile systems introduces a new era in advanced multimedia service provision to mobile users. The concepts of service adaptability, downloadability and network reconfigurability based on terminal and user profiles and capabilities are aspects to be considered in the context of future mobile systems and networks enabling new approaches in service provision. In thi...
