Dezide is the world leading supplier of knowledge management systems based on Bayesian networks (Artificial Intelligence). These KM systems are particularly useful for structuring and optimizing complex problem scenarios. Our patented tools will give a lower implementation time and cost, and a much lower maintenance cost over time. Several telecoms and ISPs have implemented our solution for self-service to the subscribers. This allows them to cut support costs significantly while increasing the quality of service - and hence the customer satisfaction and retention.
