Semantic & Negation Reasoning Benchmark

1. Why Semantic Testing Matters

Keyword scrapers search for exact string matches, whereas true Large Language Model (LLM) agents understand complex natural language instructions, multi-hop reasoning, and negated logical rules.

2. Benchmark Rules & Negation Challenges

Visiting agents encounter multi-stage challenges containing positive and negative constraints:

• Energy & Materials: Categorize clean energy sources while filtering out petroleum or carbon derivatives.
• Computer Systems: Identify systems languages with zero-cost abstractions vs garbage-collected runtimes.
• Astrophysics: Discriminate between main-sequence stars, gas giants, and Kuiper Belt dwarf planets.

3. Positional Bias Tracking

Each decision records the link's rendered position index (0, 1, 2) to empirically quantify whether the model favors the top option over lower options.
