IberLEF eHealth-KD 2019: eHealth Knowledge Discovery

Natural Language Processing (NLP) methods are increasingly being used to mine knowledge from unstructured health texts. Recent advances in health text processing techniques are encouraging researchers and health domain experts to go beyond just reading the information included in published texts (e.g. academic manuscripts, clinical reports, etc.) and structured questionnaires, to discover new knowledge by mining health contents. This has allowed other perspectives to surface that were not previously available.

Over the years many eHealth challenges have taken place, which have attempted to identify, classify, extract and link knowledge, such as Semevals, CLEF campaigns and others [1].

Inspired by previous NLP shared tasks like Semeval-2017 Task 10: ScienceIE and research lines like Teleologies [2],both not specifically focussed on the health area, and related previous TASS challenges, eHealth-KD 2019 proposes –as the previous edition eHealth-KD 2018– modeling the human language in a scenario in which Spanish electronic health documents could be machine readable from a semantic point of view. With this task, we expect to encourage the development of software technologies to automatically extract a large variety of knowledge from eHealth documents written in the Spanish Language.

Even though this challenge is oriented to the health domain, the structure of the knowledge to be extracted is general-purpose. The semantic structure proposed models four types of information units. Each one represents a specific semantic interpretation, and they make use of thirteen semantic relations among them. The following sections provide a detailed presentation of each unit and relation type. An example is provided in the following picture.

This challenge can be of interest for experts in the field of natural language processing, specifically for those working on automatic knowledge extraction and discovery. It is not a requirement to have expertise in health texts processing for dealing with the eHealth-KD task, due to the general purpose of the semantic schema defined. Nevertheless, eHealth researchers could find interesting this challenge to evaluate their technologies that rely on health domain knowledge.

Description of the Subtasks

To simplify the evaluation process, two subtasks are presented:

  1. Identification and classification of key phrases
  2. Detection of semantic relations

Submissions and evaluation

The challenge will be graded in Codalab. Details about submissions are provided here.

There are three evaluation scenarios:

  1. A main scenario covering both tasks
  2. An optional scenario evaluating subtask A
  3. An optional scenario evaluation subtask B


All the data will be made available to participants in due time. This includes training, development and test data, as well as evaluation scripts and sample submissions. More details are provided here.

Publication instructions

The following instructions are subject to change to adapt to the official IberLEF 2019 requirements.

Send your paper to our Program Comitee at chairs_eHealth-KD@googlegroups.com before June 3rd, 2019.

The Organization Committee of eHealth-KD encourages participants to submit a description paper of their systems. Submitted papers will be reviewed by a scientific committee, and only accepted papers will be published at CEUR. The proceedings of eHealth-KD will be jointly published with the proceedings of all tasks of IberLEF 2019. The submitted papers will be peer-reviewed by a Program Commitee which is composed by all the participants and the Organization Commitee.

The manuscripts must satisfy the following rules:

Up to 6 pages plus references formatted according to the SEPLN template.
