Abstract: The credibility assessment of the eyewitness accounts has attracted researchers from different backgrounds, including but not limited to psycholinguistics and computational linguistics. The outcomes of these methods, however, have pitfalls for different reasons and Yuille et al (1989) advocated for a multidisciplinary and multidimensional approach to the information construction of the evidence. A simulation experiment is adopted to elicit a group of true eyewitness accounts as well as a group of fabricated ones before they are compared from the perspective of discourse information analysis. The result shows the DIAbased linguistic approach can distinguish the true accounts from the fabricated ones, which marks a different way in the field of credibility assessment of the eyewitness accounts.
