User Simulation for Evaluating Information Access Systems book

by

The book User Simulation for Evaluating Information Access Systems by Krisztian Balog and ChengXiang Zhai has been published by Foundations and Trends in Information Retrieval. This comprehensive monograph delves into the pivotal role of user simulation in assessing the effectiveness of information access systems, such as search engines, recommender systems, and conversational assistants. A preprint is available on arXiv.

PKG API presented at WWW’24

by

The PKG API is a tool for managing personal knowledge graphs (PKGs), which has been developed by our group (Nolwenn Bernard, Ivica Kostric, Weronika Łajewska, Krisztian Balog, Petra Galuscakova, Vinay Setty, and Martin G. Skjæveland). This work is a first step toward the realization of our proposed PKG ecosystem and has been presented at the 2024 ACM Web Conference, in Singapore. Have a look at the paper or the toolkit for more details.

MovieBot 2.0 demo paper presented at WSDM’24

by

IAI MovieBot is a conversational recommender system for movies developed by members of our group, Javeria Habib, Krisztian Balog, Nolwenn Bernard, Ivica Kostric, Weronika Łajewska, Martin G. Skjæveland, and Shuo Zhang. This work has been demonstrated at the 17th ACM International Conference on Web Search and Data Mining (WSDM’24), in Merida, Mexico. Have a look at the demo paper or the repository to learn more about our movie recommender system.
