Solution

The correct answer is A - II, B - II, C - II, D - I

Key Points

• A. Text planning -> II. Natural language generation:
  • Text planning is a step in the natural language generation process. It involves deciding what content to include in a text, as well as the order in which that content should be presented. This includes planning the main points, arguments, or messages that the text will communicate.
• B. Sentence planning -> II. Natural language generation:
  • Sentence planning is another step in the language generation process. This involves deciding how individual sentences will be structured, including the ordering of words and phrases, and the selection of appropriate vocabulary. It generally comes after text planning, so that each sentence supports the overall textual structure.
• C. Sentence generation -> II. Natural language generation:
  • Sentence generation is the final step in the natural language generation process, where the structured sentences (from the planning phase), are actually generated in specific chosen language (like English, Spanish etc.). This is where the planned elements from text and sentence planning come together to create cohesive, comprehensible output.
• D. Map the input to useful representations -> I. Natural language understanding:
  • Mapping the input to useful representations is a step in natural language understanding. This means converting raw input (which is usually in the form of human language text) into a form that a machine can 'understand' and process. This could be, for example, a vector representation of a sentence in a high-dimension space, or a parse tree that represents the grammatical structure of a sentence. This process aids in interpreting the meaning of the input.
