Range As A Semantic Role

Overview

The semantic role of range describes the extent or scope of an action, state, or relationship. It often specifies the boundaries within which something occurs or applies.

Key Concepts

The range can be:

• Spatial: e.g., “The ball rolled across the field.”
• Temporal: e.g., “She worked all day.”
• Abstract: e.g., “His knowledge covers many subjects.”

Deep Dive

The range role is crucial for understanding the scope and limits of predicates. It answers questions like “how far?”, “how long?”, or “to what extent?”. It can be expressed by prepositional phrases or adverbs.

Applications

In linguistics and natural language processing, identifying the range helps in:

• Disambiguating sentence meaning.
• Improving information extraction.
• Enhancing question answering systems.

Challenges & Misconceptions

Distinguishing range from other roles like location or goal can be difficult. It’s important to note that range defines the extent, not necessarily a specific point within it.
