Basic semantic relationships

Basic semantic relationships

1. Paraphase: Two sentences that have the same meaning are called paraphrases of each other. Thus, at the sentence level, paraphrases are the equivalent of synonyms at the lexical level.

   • Examples: 1. The dog chased the cat paraphrases The cat was chased by the dog. 2.Philip purchased an automobile is a paraphrase of Philip bought a car.

2. Entailment or implication: we speak of entailment when one sentence entails that the other sentence is true, but the reverse does not hold.

   • Examples: Mary loves flowers entails Mary loves roses. Alan lives in Toronto entails Alan lives in Canada.
