iSchool researchers will present their work at The Web Conference 2021. The conference, which will be held virtually from April 12-23, will address the evolution and current state of the Web through the lens of computer science, computational social science, economics, public policy, and Web-based applications.
Assistant Professor Jodi Schneider, Associate Professor Catherine Blake, and Bioinformatics MS student Yuanxi Fu will present their paper, "Finding Keystone Citations for Constructing Validity Chains among Research Papers," at the Sci-K workshop. The paper builds on Fu & Schneider's keystone citation project and emerged from a class project in Blake's Text Mining class. In the paper, the researchers propose and evaluate "a strategy that repurposes rhetorical category classifiers for the novel application of extracting keystone citations that relate to research methods."
iSchool PhD student Haonan Wang and Computer Science PhD students Yikun Ban and Lecheng Zheng will present three papers of Associate Professor Jingrui He's research group, the iSAIL Lab. Ban will present "Local Clustering in Contextual Multi-Armed Bandits," which introduces a new bandit algorithm, LOCB for content recommendation and online advertisement; Wang will present "Controllable Gradient Item Retrieval," which solves the problem of retrieving a sequence of items with a gradual change on a certain attribute; and Zheng will present "Deep Co-Attention Network for Multi-View Subspace Learning," which provides new methodologies for social media analysis, by leveraging both the topology of the underlying social network and the content of the users' posts.
