This paper presents the solution to problems of fuzzy ranking Vietnamese documents using approach of Hedge Algebra based on envaluating an accordance of found documents by heuristic criteria. These criteria firstly are evaluated by degree of importance (weight) and then are combined following some aggregation operator to define final evaluation unique number, that will be used for sorting the documents. The experimental results are presented to show the effectiveness of the proposed solution. | ’ Tap ch´ Tin hoc v` Diˆu khiˆn hoc, , (2008), 87–96 ı a ` e e . . . ´ ´ ’. ` ` ´ ´ ´ ˘ ˆ `. ` ˆ ˆ ˆ ˆ DAI SO GIA TU VA BAI TOAN SAP XEP MO TAI LIEU TIENG VIET . . . . ˜ ´ ˆ ´ ˆ ˆ ´ ˆ ˘ TR` N THAI SO N, LE QUOC THAI, NGUYEN VAN NAM A Viˆn Cˆng nghˆ thˆng tin, Viˆn Khoa hoc v` Cˆng nghˆ Viˆt Nam e o e o e e e . . . . a o . . Abstract. This paper presents the solution to problems of fuzzy ranking Vietnamese documents using approach of Hedge Algebra based on envaluating an accordance of found documents by heuristic criteria. These criteria firstly are evaluated by degree of importance (weight) and then are combined following some aggregation operator to define final evaluation unique number, that will be used for sorting the documents. The experimental results are presented to show the effectiveness of the proposed solution. ´ ´ ´ ´ ’ T´m t˘t.
