In this paper the algorithm of construction of hierarchical classifier of short text fragments is presented. This algorithm is based on hierarchical clustering of fuzzy graph. Clustering and classification problem of short text fragments which are fully or partly context free is quite common nowadays. There are many examples of such objects: sms, twitter messages, paper and news headers. This paper is focused on classifier construction of key process indicators of strategic planning system of Russian Federation. Classifier is built on the result of clustering process. As a model for the clustering process the fuzzy graph is chosen, because its ability of natural presentation of word relations. This method allows perform clustering recursively, thus hierarchical classifier is obtained.
