This paper explores the idea of Pattern Language as a method for interaction design in a social network environment. It is the belief of the author that Pattern Language can enable interaction design to address group interaction within an “unbounded” interaction event. The aim is to define a theoretical starting point for adapting Pattern Language that addresses criteria informed by the concept...

We describe work on large scale automatic annotation of full texts of books with social tags. Our task consisted of assigning tags to the full texts of works of fiction and evaluating them against tags assigned by humans. We compared Boosting and Relevance Models (RM) methods to explore how they differ primarily in terms scalability and also annotation quality. We extended beyond the set of 50 ...

As argued elsewhere (Henningham, 1995), conservatism scales are unlike other measures of attitudes in that they need a “use by” date. The community’s evolving values, as well as changes in fashion and in acceptable behaviour, render scales measuring conservatism-liberalism products of their day and age. This is obvious by considering some of the items in the original “catchphrase” scale of Wils...

Chronic deteriorated patients have been receiving increased attention since the advent of the tranquilizing drugs. The problem of evaluating the effects of these drugs on this type of patient has become acute. Recently the authors were called upon to evaluate the therapeutic effects of a new drug, promazine, on such patients (4). The existing scales seemed ill-suited for use at this very low le...

MaxEnt’s variational principle, in conjunction with Shannon’s logarithmic information measure, yields only exponential functional forms in straightforward fashion. In this communication we show how to overcome this limitation via the incorporation, into the variational process, of suitable dynamical information. As a consequence, we are able to formulate a somewhat generalized Shannonian Maximu...

We present an efficient algorithm for computing distances in hyperbolic grids. We apply this algorithm to work efficiently with a discrete variant of the hyperbolic random graph model. This model is gaining popularity in the analysis of scale-free networks, which are ubiquitous in many fields, from social network analysis to biology. We present experimental results conducted on real world netwo...

Sustainability is a global issue concerning future generations, but steps towards sustainable development must also be taken at the spatial scales of regions and at the temporal scales of individual lives. Different scales matter in social networks and in cultural realities, too. The fact that relatively small regions can dominate global markets for products based on continuous innovation point...

In this paper, we report the result of a research project investigating social aspects of knowledge sharing and development. Prior research in a consulting firm revealed that respondents recognized five kinds of informational benefits when consulting others: solutions, meta-knowledge, problem reformulation, validation and legitimation. We employed these dimensions in a systematic network analys...
