Title: "Defining the Multistakeholder Recommendation"
Recommender systems are the essential part of many existing web technologies including ecommerce, entertainment, transportation, education, etc. Most of the existing work on recommender systems has focused on personalization: making recommendations more accurate to the user. While this is indeed a reasonable consideration, it does not cover the complexity of many existing applications in which recommemder systems are being used. That is, there might be multiple stakeholders whose needs and interests should be taken into account. We will explore one specific area of this new paradigm in which the system’s objectives as a stakeholder should be also incorporated in the recommendation generation along with the users’ preferences. In addition, we will discuss some methods to incorporate one example of system objective which is promoting less popular items in the recommendation algorithms.
Abdollahpouri is a PhD student in the Department of Information Science at CU Boulder. His thesis is on recommender systems and personalization. In particular, he is working on a new topic called multistakeholder recommendation, where the goal is to generate personalized recommendations for users while satisfying the needs and interests of multiple stakeholders such as item providers, intermediary partners, the recommendation platform and so on. He holds a bachelor's degree in computer engineering and also a master's degree in artificial intelligence from Bu-Ali Sina university and Iran University of Science and Technology, respectively. During his PhD program, he has done two internships at Pandora Media in summer 2017 and 2018 as a research data scientist working on machine learning and recommendation algorithms for improving the performance of their music recommendations
Title: "Why Computer Science Faculty Change Their Teaching"
This talk explores results from the second stage of a two-part research project designed to uncover what influences computer science (CS) faculty to adopt new teaching practices. In the first phase, we conducted theory-driven interviews, classroom observations and focus groups with faculty to better understand the organizational, individual and social factors that influence their adoption of new teaching strategies. To investigate the prevalence of these qualitative findings, we collected and analyzed survey data from 821 CS faculty at approximately 595 U.S. institutions during the second phase of the project. Results of the quantitative phase show that CS faculty who tried an innovation were motivated primarily by concerns for students learning and course experience, including their engagement and participation. Also important were the “fit” with existing practices and tools, and the logistics of implementing an innovation. Factors that reduced faculty willingness to try an innovation include a lack of time, logistical issues, and satisfaction with their current teaching practices. Faculty learned about the innovations they later adopted through presentations and workshops at conferences and at their home institutions, and through conversations with respected colleagues who teach in similar contexts. Implications for encouraging more widespread usage of teaching techniques that improve diversity and student learning are discussed.
Hovey is a research associate in the Department of Information Science at CU Boulder and a social research scientist for the National Center for Women & Information Technology (NCWIT). His research focuses on issues related to increasing gender parity in undergraduate and graduate computing programs, including how individual, social, and organizational features influence faculty to adopt student-centered teaching practices. Chris received his bachelor's degree in sociology from CU Boulder and his MA and PhD in sociology from Northeastern University in Boston.
