Papers

The most cited first (OpenAlex and our library).

  1. Statistical Properties of Probabilistic Context-Free Grammars (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 (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.
