* Overview
Conceptual modeling has enjoyed substantial growth over the past decades in diverse fields such as Information Systems Analysis, Software Engineering, Enterprise Architecture, Business Analysis and Business Process Engineering. A plethora of conceptual modeling languages, frameworks and systems have been proposed, promising to facilitate activities such as communication, design, documentation or decision making. Success in designing a conceptual modeling system is, however, predicated on demonstrably attaining language goals through observing their use in practical scenarios. At the same time, the way individuals and groups produce and consume models gives raise to cognitive, behavioral, organizational or other phenomena, whose systematic observation may help us better understand how models are used in practice and how we can make them more effective.

* Aim and Topics
We aim at bringing together researchers with an interest in the empirical investigation of conceptual modeling systems and practices. We invite reports on finished, on-going or proposed empirical studies and theoretical, review and experience papers about empirical research in conceptual modeling. Examples of contributions include but are not limited:
. Complete, on-going or planned empirical studies in Conceptual Modeling.
. Literature reviews on empirical research in Conceptual Modeling.
. Theoretical/philosophical positions on Empirical Conceptual Modeling.
. Discussions/positions on statistical and methodological issues.
. Lessons learned from past studies.

* Submissions
We solicit three types of papers:
. Full study papers describing a completed study, including negative results and early exploratory efforts.
. Work-in-progress papers describing a planned study or study in progress.
. Position, vision and lessons papers about the use of empirical methods for conceptual modelling.

Maximum length for submissions is 14 LNCS pages max including references. The EmpER’21 accepted papers will be published within the ER Workshop proceedings, in the Springer LNCS Series.

* Format and Duration
The workshop will consist of paper presentations with an emphasis on discussion. Time permitting, papers presenting on-going studies will have a discussion session led by a designated member of the program committee.

* Location
The workshop is co-located with the 40th International Conference on Conceptual Modeling (ER 2021), which will take place in St. John’s, Canada.
Format is blended and participants can join on-line or in-person.
