The choice behaviour of alternatives can be expressed as a two-stage process: a stage to recognize the character of each alternative and a stage of decision making based on the character, i.e., ‘recognize’ and ‘choose’ stages. Many of the existing studies on reputation and opinion analysis focus on the information extraction of the ‘recognize’ stage, whereas this paper describes the entire choice behaviour including the ‘choose’ stage and tries to capture unknown elements. This paper reports the selection process throughout the ‘choose’ stage, which can be described as conforming to Elimination-By-Aspects (EBA). EBA performs the selection by eliminating according to whether the alternative has the feature (aspect) in question or not. This paper achieves this process with choice strategies that eliminate or retain the alternatives. Moreover, it is insufficient to simply handle the appeared information, hence, it is necessary to read between the lines. Finally, we can know the merits and demerits of the alternatives by analyzing the reason for the triggering of selection or elimination.
