Earlier probabilistic models, such as the standard P-CFG, condition each rule choice on very little context. The authors propose History-based Grammars (HBG), a generative model in which the probability of expanding each node may depend on anything already built in… 2. **[Using Lexical Dependency and Ontological Knowledge to Improve a Detailed Syntactic and Semantic Tagger of English](https://md.research.elamur.ai/free/en/papers/finch-2006-lexical-dependency-ontological-knowledge-improve/)** *(2006 · 3 citations)* The paper tags each word with a syntactic tag and a broad semantic class at once, using a maximum-entropy tagger with a beam search from left to right. ## All works 3 works of theirs in our library, the most cited first; 2 with a page here, the others link their original until we summarise them. 1. **[Towards History-based Grammars: Using Richer Models for Probabilistic Parsing](https://md.research.elamur.ai/free/en/papers/black-1993-history-based-grammars-richer-models/) [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/)**Ezra Black, Fred Jelinek, John Lafrerty, et al.*1993 · 211 citations* 2. **[Development and Evaluation of a Broad-Coverage Probabilistic Grammar of English-Language Computer Manuals ↗](https://aclanthology.org/P92-1024/) 30th Annual Meeting of the Association for Computational Linguistics · no summary yet**Ezra Black, John Lafferty, Salim Roukos*1992 · 102 citations* 3.
