In this paper, we present an innovative chart mining technique for improving parse cover- age based on partial parse outputs from preci- sion grammars. The general approach of min- ing features from partial analyses is applica- ble to a range of lexical acquisition tasks, and is particularly suited to domain-specific lexi- cal tuning and lexical acquisition using low- coverage grammars. As an illustration of the functionality of our proposed technique, we develop a lexical acquisition model for En- glish verb particle constructions which oper- ates over unlexicalised features mined from a partial parsing chart. The proposed tech- nique is shown to outperform a state-of-the-art parser over the target task, despite being based on relatively simplistic features.
