HICSS – Automatic Text Analysis of Values in the Enron Email Dataset: Clustering a Social Network Using the Value Patterns of Actors
2010 43rd Hawaii International Conference on System Sciences, 2010Co-Authors: Yingjie Zhou, Kenneth R. Fleischmann, William A. WallaceAbstract:Widely discussed in the mass media, Web 2.0, or social software, has also drawn the attention of researchers, developing into a whole new research area. With Web 2.0’s further development, corporations aim to adopt its technologies and transfer its benefits, such as enhanced collaboration and knowledge sharing, to their organizations. Whether any of these benefits also apply in an organizational conText and whether there are further, still uncovered, benefits remains unclear. Furthermore, research in this area is still in its early stages, thus hampering progress towards qualitative and quantitative models that could provide answers. In order to encourage further progress in this area, we reviewed the existing research on corporate blogging and identified 24 articles that investigate the topic. Using the framework by Ives et al. [18], we categorized the articles for further Analysis. By means of process theory, we build a conceptual model and identify the antecedents and consequences of internal corporate weblog usage. Our findings suggest that usage is driven by organizational culture, as well as by attitudes towards blogging. In addition, the benefits of weblog usage are centered on community benefits.

Automatic Text Analysis of Values in the Enron Email Dataset: Clustering a Social Network Using the Value Patterns of Actors
2010 43rd Hawaii International Conference on System Sciences, 2010Co-Authors: Yingjie Zhou, Kenneth R. Fleischmann, William A. WallaceAbstract:This paper describes an Automatic Text Analysis of values contained in the Enron email dataset that seeks to explore the potential to apply value patterns to cluster a social network. Two hypotheses are posed: individuals communicate more frequently with other individuals who share similar value patterns than with individuals with different value patterns; and people who communicate more frequently with each other share similar value patterns. The first hypothesis is supported: indeed, individuals were found to communicate more frequently with individuals who share similar value patterns, and further, the extent to which this is true appears to depend at least in part on the value patterns themselves. However, the second hypothesis is not supported – people who communicate more frequently with each other do not necessarily all fit into a particular value type. Thus, values have utility as a novel tool for social network Analysis.

Smart City Analytics: state of the art and future perspectives
Interaction Design and Architecture(s), 2014Co-Authors: Carlo Giovannella, Mihai Dascalu, Federico ScacciaAbstract:In accordance with a “people centred” vision, this paper critically examines current approaches to smart cities benchmarking. In particular, by means of correlation Analysis and Principal Component Analysis (PCA) we put in evidence current limitations of city rankings and, as well, the emergence of different perspectives for data interpretations. To follow, a possible redesign of the “Smart Cities Analytics” grounded on the traces left by individuals, is suggested. In particular, as an example, we focus on the potential of Automatic Text Analysis tools to extract people perceptions and expectations that, in turns, demonstrate the need to integrate bottom-up and top-down approaches to city benchmarking. Finally a novel definition of smart city is proposed based on the territorial state of flow and, as a consequence, a novel path toward smart city benchmarking is brought forward.

Monitoring Learning Experiences and Styles: The Socio-emotional Level
2010 10th IEEE International Conference on Advanced Learning Technologies, 2010Co-Authors: Chiara Spadavecchia, Carlo GiovannellaAbstract:This article describes the integration within an on-line learning environment – LIFE (Learning in an Interacting Framework to Experience) – of two tools that have been designed to allow “quasi-real-time” and “in situ” monitoring of complex educational “experiences/processes”, thanks to the Analysis of the traces left by the learners. The two tools allow to monitor and analyze, respectively, the level of social interaction – through techniques of social network Analysis (SNA) – and the emotional state of learners through Automatic Text Analysis (ATA). When combined, the two tools allow also to monitor the emotional relationships and, ultimately, the ‘social’ emotional state of the community. As case history we present and discuss the results of a monitoring experiment conducted on an educational process which lasts five months (the second part of a master’s degree in “E-Learning: methods, techniques and applications”).
