Abstract: We discussed polysemy analysis and semantic analysis based on formal concept analysis. On polysemy analysis, we generated a decision context based on relations between word meanings and the corresponding parts of speech.And then we extracted the decision rules from the context and gave them explanations. On semantic analysis,we formed a formal context based on relations between linguistic objects and their semantic features, and analyzed them according to formal concept analysis. Experiments show that we can not only classify the linguistic objects easily, but view reladons between different word classifications intuitively, and that formal concept analysis is an efficient tool for semantic analysis.

Key words: Formal concept analysis, Concept lattice, Polysemy, Semantic analysis
