... EFFICIENT INCREMENTAL PROCESSING WITH CATEGORIAL GRAMMAR Abstract Some problems are discussed that arise for incremental pro- cessing using certain flezible categorial grammars, ... them as a ba- sis for incremental processing. Then, we propose a grammar that avoids these problems, and demon- strate how it may be used for efficient incremental processing. Mark Hepple...

... authors also justified their method by showing that with feature hashing, dot- product is unbiased, and the length of each vector is well-preserved with high probability under some conditions. Plausibly ... explain in detail. In NLP, features can be often expediently expressed with strings. For in- stance, a feature ‘the current word ends with -ing’ can be expressed as a string cur:end...

We employ hierarchical agglomerative clustering with a similarity metric that considers featu...

This power .of choice, coupled with an ability to express co-occurrence constraints over arbitrary ... languages (e,g., Subject-Ve~ agreement). Roughly, one is allowed to associate featur~ with lexical entries and with the non-terminals of specified context-free rules; these featur...

... ABSTRACT* From a processing point of view, however, flexible categorial systems are problematic, since they introduce spurious ambiguity. In this paper, we present a flexible categorial grammar ... efficient processing is possible. 1. Flexibility vs. Ambiguity Categorial Grammars owe much of their popularity to the fact that they allow for various degrees of flexibility...

We used an in vitro-selected pistol-like (PL) DNAzyme as a DNA scaffold for designing a DNAzyme with dual catalytic ...
