Presentation of the manuscript "User Interaction Mining: Discovering the Gap Between the Conceptual Model of a Geospatial Search Engine and Its Corresponding User Mental Model" at the 22nd International Conference on Perspectives in Business Informatics Research (BIR 2023) in Ascoli Piceno, Italy on 13th September 2023. "User interaction mining: discovering the gap between the conceptual model of a geospatial search engine and its corresponding user mental model" describes a case study conducted at the National Geographic Institute of Spain. In this research, twenty-one participants, including novice and expert users, performed a search task with a new geospatial search engine. Their interactions were recorded as event logs and analysed with process mining techniques. The results helped to identify areas for improvement in product design that come from understanding the differences between the conceptual design of the interface and the mental model of the users. This case study illustrates the potential that interaction mining can add to the design and evaluation of new user interfaces.
