Combining semantic and syntactic structure for language modeling
Rens Bod
Structured language models for speech recognition have been shown to remedy the weaknesses of n-gram models. All current structured language models are, however, limited in that th…
What is the minimal set of fragments that achieves maximal parse accuracy?
Rens Bod
We aim at finding the minimal set of fragments which achieves maximal parse accuracy in Data Oriented Parsing. Experiments with the Penn Wall Street Journal treebank show that coun…
Do All Fragments Count?

An improved parser for data-oriented lexical-functional analysis
Rens Bod
We present an LFG-DOP parser which uses fragments from LFG-annotated sentences to parse new sentences. Experiments with the Verbmobil and Homecentre corpora show that (1) Viterbi n…
