## Papers

The most cited first (OpenAlex and our library).

1. **[Statistical Properties of Probabilistic Context-Free Grammars](https://md.research.elamur.ai/free/en/papers/chi-1999-statistical-properties-probabilistic-context-free/)** *(1999 · 145 citations)* This theoretical article addresses when probabilistic context-free grammars (PCFGs) define proper distributions over finite parses, and how they relate to Gibbs (maximum-entropy) models.
2. **[Estimation of Probabilistic Context-Free Grammars](https://md.research.elamur.ai/free/en/papers/chi-1998-estimation-probabilistic-context-free-grammars/)** *(1998 · 18 citations)* A probabilistic context-free grammar (PCFG) can be "improper," or not tight: if production probabilities are chosen carelessly, some probability mass goes to derivations that never terminate, so finite parse trees together receive less than one.
