title: Clustering performance on evolving data streams: Assessing algorithms and evaluation measures within MOA

authors: Kranen, Philipp

subjects: data streams

abstract: In today's applications, evolving data streams are ubiquitous. Stream clustering algorithms were introduced to gain useful knowledge from these streams in real-time. The quality of the obtained clusterings, i.e. how good they reflect the data, can be assessed by evaluation measures. A multitude of stream clustering algorithms and evaluation measures for clusterings were introduced in the literature, however, until now there is no general tool for a direct comparison of the different algorithms or the evaluation measures. In our demo, we present a novel experimental framework for both tasks. It offers the means for extensive evaluation and visualization and is an extension of the Massive Online Analysis (MOA) software environment released under the GNU GPL License.

title: Recognising the interactive space: Marketing for social transformation

authors: Nolan, Terry

subjects: nonlinear rationality

abstract: How can the positive power of a marketing ethos and techniques solve social problems? We propose a deepened understanding of social marketing in response to the sustainability imperative, applying systems theory to elaborate the impact of social marketing campaigns and to advance our understanding of viable practices. A meta-framework reveals the complexities of human behaviour that influences the aims and outcomes of social marketing. We clarify the ontological status of the social marketing field and recognise the world view within which marketing has expanded into the public realm of social problems. We identify the problem of ontological misconception stemming from the denial of nonrational forms of human behaviour. While complicated mechanism is assumed in the problem of long-term health and prosperity for citizens and society, organic complexity is the condition faced. Conventional social marketing has provided a ‘partial’ gesture towards a solution. We outline an alternative understanding grounded in a human-centred world view of socio-economic advancement.
