Abstract With respect to group evaluation problems with linguistic preference relations on alternatives, an analysis approach is proposed. First, the rank correlation analysis and the sole reference judgment analysis are used to guide the experts to express preference information. After the transform of the partial information of the experts, two induced ordered weighted averaging aggregation operators for two-tuple are proposed for the experts' preference information with ignorance of weight. And the ranking of alternatives is obtained by comparison of two-tuple linguistic information. Finally, an application example is given to illustrate the approach proposed.
