Abstract

Fuzzy triangular number was applied in area such as risk assessment and performance evaluation because it can better express fuzzy linguistic terms. There were several approaches to measure the similarity of fuzzy triangular numbers. A new method to measure fuzzy triangular number was put forward based on the location and area of two fuzzy triangular numbers. And it was applied to collaborative filtering recommendation system to measure users' similarity. A case was used to illustrated the proposed method and the result showed that it can obtained better discriminability.
