A pilot study was conducted to compare the so called "logical relevance" and "pertinence." The results suggest that logical relevance and pertinence indeed refer to different aspects and levels of information retrieval evaluation. Proper selection of the evaluation criteria based on the evaluation purposes and levels is recommended.檢索評鑑檢索評鑑量標相關Information retrieval evaluationRelevanceLogical relevancePertinence
