What is the role of Compositionality in Computational Semantics?

  1. It allows for the meaning of complex expressions to be derived from the meanings of their constituent parts

  2. It ensures that the meaning of a sentence is always the same, regardless of the context in which it is used

  3. It helps to identify the syntactic structure of a sentence

  4. It enables the generation of natural language text from formal representations

Show answer
Correct Option: A
Explanation:

Compositionality is a fundamental principle in Computational Semantics that states that the meaning of a complex expression can be derived from the meanings of its constituent parts.

What is the relationship between Computational Semantics and Pragmatics?

  1. Computational Semantics focuses on the meaning of individual words and phrases, while Pragmatics focuses on the meaning of sentences and utterances in context

  2. Computational Semantics is a subfield of Pragmatics

  3. Pragmatics is a subfield of Computational Semantics

  4. There is no relationship between Computational Semantics and Pragmatics

Show answer
Correct Option: A
Explanation:

Computational Semantics focuses on the meaning of individual words and phrases, while Pragmatics focuses on the meaning of sentences and utterances in context.
