Who was where when?

We invite participation in the third edition of the HIPE shared task, dedicated to the extraction of person-place relations in multilingual historical documents. 

Building on the success of HIPE-2020 and HIPE-2022, which focused on entity recognition and linking, HIPE-2026 aims to enable finer-grained analysis of entities and support the accurate reconstruction of individuals' geographical and temporal trajectories.

The objective of HIPE-2026 is to build systems capable of determining whether a relation holds between a person and a location (place) mentioned in a document, and classify its temporal scope. Participants are asked to develop systems that determine, for each (person, location) pair associated with a historical document, whether the text implies that the person is at that location within the document’s temporal horizon (isAt relation), or that the person was there at some earlier moment in their life (a more general At relation), or that no such link can be established. 

Can large language models take up the challenges? Simple co-occurences of entity mentions in a text are not sufficient to uncover the implicit and explicit, temporally anchored relations between person and locations. Addressing this challenge requires temporal reasoning, geographical inference, and the interpretation of noisy historical texts (often with only fragmentary contextual cues) to classify person–location relations with varying degrees of certainty.

The task is designed to be tackled by generative AI systems/LLMs as well as by more traditional classification approaches.

HIPE-2026 features three evaluation profiles:

- Accuracy Profile: Focusing on system performance in relation classification.

- Efficiency Profile: Rewarding scalable, lightweight approaches considering model size and compute cost.

- Generalization Profile: An unseen dataset from a different domain will be included to evaluate systems’ ability to generalise beyond the newspaper domain data.

For the accuracy and efficiency profile, training and test data originate from historical newspapers in English, German, French and Luxembourgish. Entity pairs will be provided.
