Solution

The correct answer is B and C Only.

Key Points

• Conceptual dependency: While it captures some semantic relationships (meaning), it also incorporates syntactic elements like roles and case relations.
• Predicate logic: Focuses on the structure of propositions and logical connectives. It defines valid arguments based on syntactic rules, regardless of the specific meaning of the symbols.
• Slot-and-filler: Represents knowledge as entities (objects) with attributes (slots) filled with values (fillers). It emphasizes the structure of the knowledge representation, not the inherent meaning.
• Nonmonotonic systems: Deal with reasoning and inference in situations where new information might invalidate previous conclusions. This involves semantics (meaning) as new information needs to be interpreted and integrated.

Both predicate logic and slot-and-filler prioritize the structure and organization of knowledge, making them primarily syntactic in nature. They define the form of knowledge without necessarily specifying the underlying meaning.
