Research on pests and diseases expert system of urban forest based on agent

This paper applies the agent technology into the forestry pests and diseases expert system. Firstly, it introduces the agent technology and the expert system, and then a new design method is proposed, which unifies the domain expert´s experience of pest diagnosis, disease diagnosis, pests forecasting and the achievement of prevention and control technique. Beside those, the pest forecasting and diagnosis mathematical model, vector apace model and TF-IDF algorithm are also constructed, at last these methods are take into application.
