Understanding Human Preferences for Summary Designs in Online Debates Domain

Research on automatic text summarization has primarily focused on summarizing news, web pages, scientific papers, etc. While in some of these text genres, it is intuitively clear what constitutes a good summary, the issue is much less clear cut in social media scenarios like online debates, product reviews, etc., where summaries can be presented in many ways. As yet, there is no analysis about which summary representation is favored by readers. In this work, we empirically analyze this question and elicit readers’ preferences for the different designs of summaries for online debates. Seven possible summary designs in total were presented to 60 participants via an online study. Participants were asked to read and assign preference scores to each summary design. The results indicated that the combination of Chart Summary and Side-By-Side Summary is the most preferred summary design. This finding is important for future work in automatic text summarization of online debates

New Models of Technology Assessment for Development

This report explores the role that ‘new models’ of technology assessment can play in improving the lives of poor and vulnerable populations in the developing world. The ‘new models’ addressed here combine citizen and decision-maker participation with technical expertise. They are virtual and networked rather than being based in a single office of technology assessment (as was the case in the United States in the 1970s-90s). They are flexible enough to address issues across disciplines and are increasingly transnational or global in their reach and scope. The report argues that these new models of technology assessment can make a vital contribution to informing policies and strategies around innovation, particularly in developing regions. They are most beneficial if they enable the broadening out of inputs to technology assessment, and the opening up of political debate around possible directions of technological change and their interactions with social and environmental systems. Beyond the process of technology assessment itself, the report argues that governance systems within which these processes are embedded play an important role in determining the impact and effectiveness of technology assessment. Finally, the report argues for training and capacity-building in technology assessment methodologies in developing countries, and support for internationally co-ordinated technology assessment efforts to address global and regional development challenges

Designing smart markets

Electronic markets have been a core topic of information systems (IS) research for last three decades. We focus on a more recent phenomenon: smart markets. This phenomenon is starting to draw considerable interdisciplinary attention from the researchers in computer science, operations research, and economics communities. The objective of this commentary is to identify and outline fruitful research areas where IS researchers can provide valuable contributions. The idea of smart markets revolves around using theoretically supported computational tools to both understand the characteristics of complex trading environments and multiechelon markets and help human decision makers make real-time decisions in these complex environments. We outline the research opportunities for complex trading environments primarily from the perspective o

PRIMA — Privacy research through the perspective of a multidisciplinary mash up

Based on a summary description of privacy protection research within three fields of inquiry, viz. social sciences, legal science, and computer and systems sciences, we discuss multidisciplinary approaches with regard to the difficulties and the risks that they entail as well as their possible advantages. The latter include the identification of relevant perspectives of privacy, increased expressiveness in the formulation of research goals, opportunities for improved research methods, and a boost in the utility of invested research efforts

AAPOR Report on Big Data

In recent years we have seen an increase in the amount of statistics in society describing different phenomena based on so called Big Data. The term Big Data is used for a variety of data as explained in the report, many of them characterized not just by their large volume, but also by their variety and velocity, the organic way in which they are created, and the new types of processes needed to analyze them and make inference from them. The change in the nature of the new types of data, their availability, the way in which they are collected, and disseminated are fundamental. The change constitutes a paradigm shift for survey research.There is a great potential in Big Data but there are some fundamental challenges that have to be resolved before its full potential can be realized. In this report we give examples of different types of Big Data and their potential for survey research. We also describe the Big Data process and discuss its main challenges
