MedISys is a media monitoring system initially intended for news items related to human health. The
tool has how been extended by the Joint Research Centre, Universitat de Lleida and IRTA to also deal
with plant health threats. This EFSA-funded project was based on a knowledge representation
approach that generated an ontology, a formal representation of knowledge related to plant health
threats. The ontology models plant pests and diseases, together with other concepts related with
them: affected crops, hosts, vectors and symptoms. First of all, a collection of news sources related to
plant health threats was collected to be monitored by MedISys. These sources included already known
manually curated Web pages but also additional ones discovered by performing global Web searches
using terms appearing in the ontology. Then, the news items coming from these sources were filtered
using MedISys using a set of categories with keywords to identify those actually about plant health
threats. Most of these categories focused on known threats and used terms associated with the 117
pests and diseases selected at the beginning of the project. Additionally, categories for unknown
threats were also developed. In this case the categories included keywords that are usually used by
experts to describe unknown threats and keywords related with symptoms expressions. All these
MedISys categories combined provide mechanism to monitor plant health threats mentions in media,
from newspapers to social media, ranging from those that explicitly mention a named threat (useful to
monitor re-emerging threats or their spread) to those related to unknown ones (to monitor potential
new threats). The project concluded with an evaluation of the e-mail alerts and reports generated by
MedISys based on the previous categories. A survey and tests with real users were conducted and the
results analysed to generate a set of recommendations and improvements to facilitate the use of
MedISys as a plant health threats monitoring tool.
