Interpretation of metaphor and the principle of conceptual fuzzy sets

The utterance `She is a bulldozer' is not interpreted by a person to refer to a piece of construction equipment but to mean something like `She is powerful'. Thus, interpretations of language are affected by contexts. This phenomenon does not only apply to metaphor. According to `Metaphors We Live By' (Lakoff and Johnson), our ordinary conceptual system, in terms of which we both think and act, is fundamentally metaphorical in nature. The subject of research is a typical metaphor `A is B', which is a foundation of interpretations, and we propose the model interpretation of metaphor along with the principle of conceptual fuzzy sets. We used news documents as a corpus, experimented on the appropriateness of a proposed system, and then evaluated it.
