[Talk Summary 8] Data-Driven Science of Science

Dr. Ying Ding from School of Informatics and Computing, Indiana University gave the talk "Data-Driven Science of Science" on November, 04, 2016 at School of Information Science, University of Pittsburgh.

In the talk. Dr. Ding presented an overview about Data Science and the current layers of bibliometrics, which are macro level in complex network, meso level in bibliometrics, and micro level in collaboration and team science. Currently, most of research work has been focusing on analyzing data from complex network and bibliometrics. Dr. Ding suggested that collaboration and team science, as a micro level, should be a new trend to have the attention of data scientists.

In addition, Dr. Ding concisely summarized her work related to Data Science which is beyond the bibliometrics. The three following are the main of her research:
  • Data-Driven Discovery: entity metrics, computational hypothesis generation, and digital innovation (e.g. machine reading)
  • Data-Driven Decision Making: understanding scientific career, understanding scientific collaboration, and understanding scientific success and innovation.
  • Data-Driven Knowledge Discovery
In details, she stated some potential, interesting ideas and techniques related to her work. Speaking of keywords, how does a keyword shift from one topic to another topic (or one domain to another domain). How can we increase the strength of relationship between two nodes in a graph in a far distance? Figuring out those kinds of relationship helps us to discover the knowledge which is difficult to be known. In her research, she tried to find patterns in the graph through extracting the same sub-structure of two entities, the semantic relationship, and the gene ontology.

At the end of the talk, Dr. Ding discussed a new potential topic in machine learning, lifelong machine learning. Lifelong learning which learns as humans retains the knowledge gained from the past learning and uses the knowledge to help future learning and problem solving.

Personalized Access to Scientific Publications: from Recommendation to Explanation

Dario De Nart, Felice Ferrara, and Carlo Tasso ( UMAP-2013 ) http://link.springer.com/chapter/10.1007/978-3-642-38844-6_26 In the paper “Personalized Access to Scientific Publications: from Recommendation to Explanation”, Dario De Nart et al. present a Recommender and Explanation System (RES) that is able to recommend scientific publication and show explanation to users.  In order to do recommendation, Dario De Nart et al., firstly, use the The Dikpe Keyphrase extraction algorithm introduced by Pudota (2010) to extract keyphrases from papers. Each keyphrase has a weight called keyphraseness that reveals the several lexical and statistical indicators exploited in the extraction process. Higher is the keyphraseness, more relevant is the KP. For each paper in the collection, they represent it as a conceptual graph. Each node in the graph is a term broken down from a KP. Two nodes are connected when they appear in the same KP. For instance, the KP “document retrieval” is split into tw

FolkTrails: Interpreting Navigation Behavior in a Social Tagging System

Thomas Niebler, Martin Becker, Daniel Zoller, Stephan Doerfel, & Andreas Hotho ( CIKM-2016 ) http://dl.acm.org/citation.cfm?doid=2983323.2983686 In the paper “FolkTrails: Interpreting Navigation Behavior in a Social Tagging System”, Niebler et al. present an investigate navigation trails in the popular scholarly social tagging system BibSonomy. They tried to understand users’ dynamic browsing behaviors on this kind of systems, how individual users behave differently on navigation, and whether the semantic nature of the underlying folksonomy can help to explain navigation. Firstly, Niebler et al. study different hypotheses about the navigational user behavior in Bibsonomy, a social bookmarking system. They test these hypotheses by using HypTrails, an approach utilizing first-order Markov chain models and Bayesian inference for expressing and comparing hypotheses about human trails. These hypotheses include: Uniform hypothesis: serves as a baseline, users randomly pick a l

Personalized Social Search Based on the User’s Social Network

David Carmel et al. - IBM Research Lab in Haifa, Israel ( CIKM-2009 ) http://dl.acm.org/citation.cfm?doid=1645953.1646109 Personalizing the search process considers the searcher’s personal attributes & preferences so that the system is able to, for example, do personalized query expansion, re-rank the result list or filter presented information. However, few studies consider the preferences of the user’s related people in social network which can be utilized to enrich the user’s preferences. In the paper “Personalized Social Search Based on the User’s Social Network”, Carmel et al. presents a study that leverages both aforementioned information resources to improve social search, which is the search process over “social” data (e.g., documents or people) gathered from Web 2.0 applications. Particularly, they plan to re-rank search results by considering the relationships with other users in the searcher’s social network (SN). Firstly, Carmel et al. build user profiles from t
