This paper introduces the Dezert-Smarandache (DSm) Field and Linear Algebra of Refined Labels (FLARL) useful for dealing accurately with qualitative information expressed in terms of qualitative belief functions. This work extends substantially our previous works done in DSmT framework which were mainly based on approximate qualitative operators. Here, new well justified accurate basic operators on qualitative labels (addition, subtraction, multiplication, division, root, power, etc) are presented. The end of this paper is devoted to an exemples of qualitative fusion rules based on this new FLARL approach for decision-making support.
