Abstract: With respect to a kind of clustering problem of which both the value of characteristic index and weight of index are of linguistic assessment information, a new approach is presented for cluster analysis. Defining such problems and by virtue of the conventional fuzzy cluster analysis via digital information networking. All the abbreviations are converted then expressed into triangular fuzzy numbers to give the computational steps so as to solve the clustering problems of multi-index linguistic assessment information. A numerical example is given to illustrate the new approach to cluster analysis, which is available to widen the applications of networking cluster analysis to multi-index linguistic assessment information.
