While the methodological frameworks for selecting these properties provide a good foundation, a continued discussion is necessary for further clarifying and improving the available methods. This paper advances earlier work by building on the existing InSPECT framework and improving its capabilities of working with complex/compound objects like blogs. The modifications enable a more thorough analysis of object structures, accentuate the differences and similarities between the framework’s two streams of analysis (i.e. Object and Stakeholder analysis) and, subsequently, improve the final reformulation of the properties. To demonstrate the applicability of the modified framework, thepaper presents a use case of a blog preservation initiative that is informed by stakeholder interviews and evaluation of structural and technological foundations of blogs. It concludes by discussing the limitations of the approach and suggesting directions for future research.}}, author = {{Stepanyan, Karen and Gkotsis, George and Kalb, Hendrik and Kim, Yunhyong and Cristea, Alexandra I. and Joy, Mike and Trier, Matthias and Ross, Seamus}}, booktitle = {{iPress 2012}}, editor = {{Moore, Reagan and Ashley, Kevin and Ross, Seamus}}, keywords = {{Blogs, Weblogs, Digital Preservation, Significant Properties}}, pages = {{218--224}}, publisher = {{University of Toronto Press}}, title = {{{Blogs as Objects of Preservation: Advancing the Discussion on Significant Properties}}}, year = {{2012}}, } @inproceedings{13326, abstract = {{Communication within online social network applications enables users to express and share sentiments electronically. Existing studies examined the existence or distribution of sentiments in online communication at a general level or in small-observed groups. Our paper extends this research by analyzing sentiment exchange within social networks from an ego-network perspective. We draw from research on social influence and social attachment to develop theories of node polarization, balance effects and sentiment mirroring within communication dyads. Our empirical analysis covers a multitude of social networks in which the sentiment valence of all messages was determined. Subsequently we studied ego-networks of focal actors (ego) and their immediate contacts. Results support our theories and indicate that actors develop polarized sentiments towards individual peers but keep sentiment in balance on the ego-network level. Further, pairs of nodes tend to establish similar attitudes towards each other leading to stable and polarized positive or negative relationships}}, author = {{Hillmann, Robert and Trier, Matthias}}, booktitle = {{AMCIS 2012 Proceedings}}, editor = {{Joshi, K.D. and Yoo, Youngjin}}, keywords = {{Social Network Analysis, Ego-Network Analysis, Node Polarization, Sentiment Dissemination}}, publisher = {{Association for Information Systems.

While various studies have inquired social-psychological influenceson the intention to contribute to an individual blog, the perceptions related to creating such a common valuable good have not yet been focussed. Therefore, we introduce a new construct – the oeuvre of blogging – to better account for the notion of the blogosphere as a collective outcome. Furthermore, we propose a research model to inquire the influence of individual and collective beliefs on the oeuvre in comparison to short-term blogging activity. We conducted an online survey with 509 international distributed bloggers to test our model.

So far, very little is known about the relationship between sentiments and network emergence, dissemination patternsand possible differences between positive and negative sentiments. The dissemination patterns analyzed in this study consist of network motifs based on triples of actors and the ties among them. These motifs are associated with common social network effects to derive meaningful insights about dissemination activities. The data basis includes several thousand social networks with textual messages classified according to embedded positive and negative sentiments. Based on this data, sub-networks are extracted and analyzed with a dynamic network motif analysis to determine dissemination patterns and associated network effects. Results indicate that the emergence of digital social networks exhibits a strong tendency towards reciprocity, followed by the dominance ofhierarchy as an intermediate step leading to social clustering with hubs and transitivity effects for both positive and negative sentiments to the same extend. Sentiments embedded in exchanged textual messages do only play a secondary role in network emergence and do not express differences regarding the emergence of network patterns.}}, author = {{Hillmann, Robert and Trier, Matthias}}, booktitle = {{Proceedings of the 2012 IEEE/ACM International Conference on Advances in Social Networks Analysis and Mining}}, isbn = {{9780769547992}}, keywords = {{Social Network Analysis, Dynamic Network Motif Analysis, Sentiment Dissemination, Networking Effects, Triads}}, pages = {{510--515}}, publisher = {{IEEE}}, title = {{{Dissemination Patterns and Associated Network Effects of Sentiments in Social Networks}}}, year = {{2012}}, } @misc{13462, author = {{Lewis, Peter and Platzner, Marco and Yao, Xin}}, publisher = {{Awareness Magazine}}, title = {{{An outlook for self-awareness in computing systems}}}, year = {{2012}}, } @inbook{10153, author = {{Hüllermeier, Eyke}}, booktitle = {{Combining Experimentation and Theory}}, editor = {{Trillas, E. and Bonissone, P.P. and Magdalena, L. and Kacprzyk, J.}}, pages = {{123--135}}, publisher = {{Springer}}, title = {{{Fuzzy rules in data mining: From fuzzy associations to gradual dependencies}}}, volume = {{271}}, year = {{2012}}, } @article{10170, author = {{Brinkmann, Gunnar and Crevals, Simon and Melot, Hadrien and Rylands, Leanne J. and Steffen, Eckhard}}, journal = {{Discrete Mathematics. and Theoretical Computer Science}}, pages = {{159--174}}, title = {{{α-labelings and the structure of trees with nonzero α-deficit }}}, volume = {{14.1}}, year = {{2012}}, } @article{10171, author = {{Steffen, Eckhard}}, journal = {{Discrete Mathematics}}, pages = {{2757--2759}}, title = {{{Nearly nowhere-zero r-flow graphs}}}, volume = {{312}}, year = {{2012}}, } @article{10172, author = {{Mkrtchyan, Vahan and Steffen, Eckhard}}, journal = {{J.
