A Latent Variable Parser
Lexicalization has been shown to be useful in more general parsing applications due to lexical dependencies in constituent parsing (e.g.
A Latent Variable Parser
However, topological fields explain a higher level of structure pertaining to clause-level word order, and we hypothesize that lexicalization is unlikely to be helpful.
Experiments
We hypothesized earlier that lexicalization is unlikely to give us much improvement in performance, because topological fields work on a domain that is higher than that of lexical dependencies such as subcategorization frames.
Experiments
However, given the locally independent nature of legitimate parentheticals, a limited form of lexicalization or some other form of stronger contextual information might be needed to improve identification performance.
Introduction
In Dubey and Keller (2003), PCFG parsing of NEGRA is improved by using sister-head dependencies, which outperforms standard head lexicalization as well as an unlexicalized model.

Experiments
Figure 4: Coverage of lexicalized STSG rules on bilingual phrases.
Experiments
We extracted phrase pairs from the training data to investigate how many phrase pairs can be captured by lexicalized tree-to-tree rules that contain only terminals.
Rule Extraction
If the tree contains only one node, it must be a lexicalized frontier node;
Rule Extraction
If the tree contains more than one nodes, its leaves are either non-lexicalized frontier nodes or lexicalized non-frontier nodes.

Abstract
By adding features over CCG word-word dependencies and lexicalized verbal subcategorization frames (“supertags”), we can obtain an F-score that is substantially better than a previous CCG-based SRL system and competitive with the current state of the art.
Potential Advantages to using CCG
Another advantage of a CCG-based approach (and lexicalist approaches in general) is the ability to encode verb-specific argument mappings.
Results
We argue that, especially in the heaVily lexicalized CCG framework, headword evaluation is more appropriate, reflecting the emphasis on headword combinatorics in the CCG formalism.
