AGROMENTORIS aims to develop a knowledge based system, which can assist farmers, agronomists and other agro stakeholders to increase agricultural production performance. This will be achieved by combining knowledge of the main factors of influence on the production: diseases, environmental conditions, cultivating methods and treatment. The project aims to implement a knowledge base, which will include the main diseases affecting the species that comprise Greek agricultural production. Three key services will be provided. The first is a browsing capability over the knowledge base providing encyclopedic information about a given plant. The second will provide identification of a disease (and disease stage) through a camera image and a relevant query to the knowledge base. The third will be an alerting service, to interested farmers, when weather conditions will change negatively the evolution of an existing disease or will create favorable conditions for the appearance of a new one. Over time the knowledge base will also cover the Balkan and Mediterranean regions allowing the offering of the same services in a wider audience. Localised knowledge and conditions will be included in the knowledge base in order to maximize relevance to each area of interest in the same or a different country.
