Special Session: Trends & Controversies in Data Science
Aims and scope
As an emerging area, data science is facing great opportunities as well as challenges.Often arguments exist: What is data science? Why data science? We have information science already, why do we need data science? Do we need analytics science? Is analytics new? What is the difference between statistics and data analytics? What makes a data scientist?
We believe that a special session on Trends and Controversy about data science and advanced analytics could bring insights from different mindsets for the healthy development of the science and society. Accordingly, this T&C special session will host talks by invitation to outline different views about today and future of data science. Invited speakers can contribute a paper (in the same format as the main conference submissions but could be less than 7 pages) to the special session, which will be handled by program co-chairs and accepted into the main conference proceeding probably by addressing comments from the program co-chairs.
Topic of interests
We expect insightful talks about forward-thinking, big thinking, original research, critical reflection and questioning on existing theories and tools, and/or innovative insights about data science, big data, advanced analytics.
Nominations to this T&C special sessions are welcome, please contact firstname.lastname@example.org.

|Title: Assessing the Longevity of Online Videos: a New Insight of a Video’s Quality|
Recommending valuable videos to viewers is always crucial to an online video website and its related third parties. More particularly, what features and methods to be selected to assess the quality of online videos is still an on-going research topic. Unlike previous work attempted to evaluate a video only by its view count (a.k.a. popularity), this article proposes an additional scoring mechanism to capture a video’s long-lasting value (a.k.a. longevity) to assist the judgment of its quality. Generally speaking, a longevous video tends to be watched frequently and therefore is considered to be more valuable. We introduce the concept of latent social impulses and the necessity of using them while measuring a video’s longevity. When deriving latent social impulses, we view the video website as a digital signal filter and formulate the task as a least squares problem. The proposed longevity computation is based on the derived social impulses, and we use experiments to directly show that the computed longevity scores are able to capture overlooked information by popularity measure.

|Title: Scalable learning of Bayesian network classifiers|
I present our work on highly-scalable out-of-core techniques for learning well-calibrated Bayesian network classifiers. Our techniques are based on a novel hybrid generative and discriminative learning paradigm. These algorithms
Despite their computationally efficiency the new algorithms deliver classification accuracy that is competitive with stateoftheart incore discriminative learning techniques.

|Title: Generating, Communicating, Accessing and Analyzing Data in a Context Aware Perspective|
The Internet of Things and the Web of Things have made context awareness a central issue in defining complex autonomic systems that rely on various layers, including devices, communications and applications. The spread usage of mobile devices that allow users to generate and access distributed data makes it extremely important to organize the forwarding and gathering of such data in a user centered way, which may support a targeted process of data analytics. Data science should strongly take into account the individual and her/his needs to look at data from a personal perspective. In this contribution an integrated view of context awareness is presented, with the several technological and scientific issues that it raises.
Bio for Prof Gabriella Pasi:
Gabriella Pasi is a professor at University of Milano Bicocca, Department of Informatics, Systems and Communication. Since 1989 the research activity of Gabriella Pasi is aimed at proposing new models and systems for a flexible and personalized management and access to information. By flexibility is meant the ability to deal with both precise and imperfect information, i.e. information affected by imprecision/vagueness and/or uncertainty. To this aim she applied soft computing techniques, based on fuzzy set theory, possibility theory, multi-criteria decision making and associative neural networks as means to design flexible information systems.

|Title: Why the worlds of MOOCs and Big Data do not collide?|
MOOCs are a new popular trend of providing online courses at a very large scale. This new popular world-wide phenomenon is yielding a very large amount of data and opportunities for analysis. Big Data on the other hand is the integration of large volumes of data coming from disparate sources at a rapid pace and can produce added data value and insight. It seems that a marriage between the two is inevitable and natural and data science can be profitable to improve the experience on MOOCs. Yet, even the techniques proposed in education data mining are not adopted in current MOOCs to enhance the involvement of learners and the evaluation of the learning. What can be done for the union of data science with MOOCs?
