Evaluation Task @ MDTT 2026

A HEREDITARY Challenge

24 June 2026, Zadar, Croatia

DETECH: DEfinition and Term Extraction CHallenge


DETECH 2026 will be a hybrid event


We are happy to announce that DETECH 2026 is a co-located event at MDTT 2026!


Challenge

The DEfinition and Term Extraction CHallenge (DETECH) focuses on the automatic extraction of domain-specific terms and the generation of natural language definitions for medical concepts.

DETECH aims to advance research on explainable, data-driven medical terminology by combining term extraction and definition generation into a unified challenge.

Organized within the HEREDITARY project, DETECH inaugurates a new evaluation challenge dedicated to the intersection of terminology, NLP, and biomedical text analysis. It will take place as a satellite event of Multilingual Digital Terminology Today (MDTT) 2026, scheduled for June 24, 2026.

The DETECH 2026 edition explores the gut–brain interplay, a domain at the crossroads of gastroenterology, neuroscience, and genetics. It provides a realistic testbed for evaluating automatic methods that identify and define specialized concepts in complex medical communication.

The challenge is organized around the following tasks:


The provisional agenda of the challenge is the following:

Participation

We welcome participation from academic, research, and industry teams working in NLP, terminology, lexicography, or biomedical informatics.

In particular:

  • Up to five runs per subtask per team are allowed.
  • External resources (e.g., pre-trained models, lexicons, ontologies) are permitted but must be clearly documented.
  • Manual runs are accepted but will not be ranked.
  • Registration details will be available (soon) on this website.

Evaluation

Each run will be evaluated according to the following measures:

  • Task A – Term Extraction: Micro-F1 - how consistently a system detects every instance of a term across the corpus - and Type-F1 - how well the system identifies the distinct terminology of the domain.
  • Task B – Definition Generation: BLEU Score, BERTScore and additional manual/qualitative check for evaluating the informativeness and linguistic quality of definitions.

Submissions

Participants must submit a technical report describing their approach, experiments, and results.
Reports must be in the CEUR-ART single-column style.

Templates:

The instruction for the submission of papers will be available soon.


Reports will undergo a peer review and accepted papers will be published on the online open-access platform CEUR-WS. Proceedings published with CEUR-WS are indexed in Scopus.

It is mandatory that at least one author of each accepted paper registers for the challenge to present the work and have the paper published in the proceedings.


Post-Conference Selected Papers Publication

Authors of the accepted contributions to the conference will be invited to submit an extended version of the paper for a journal or a volume. More information will be announced during the conference.
