AGAINST FEATURE “COPYING”

A simple feature-copying approach for long-distance dependencies

This paper is concerned with statistical methods for treating long-distance dependencies. We focus in particular on a case of substantial recent interest: that of long-distance dependency effects in entity extraction. We introduce a new approach to capturing these effects through a simple feature copying preprocess, and demonstrate substantial performance gains on several entity extraction task...

Beyond Copying

Smart copying

Can imitation be considered one of the most successful strategies in business? My answer is " yes ". It appears that this topic is getting more and more attention nowadays. It is well known that Apple's success can be attributed to taking existing ideas and repackaging them with excellent design. However, no one can readily blame Steven Jobs for lacking originality. Even if the ideas for his co...

Sidewards without copying

A traditional movement step relates a single source position to a single c-commanding target position, and never moves an argument to another argument position. But head movement involves non-c-command relations, and control relates two argument positions that are not always in a c-command relation. Special mechanisms could be invoked for these things, but a different strategy slightly generali...

Copying and Comparing : Problems

In object oriented programming, it is sometimes necessary to copy objects and to compare them for equality or inequality. We discuss some of the issues involved in copying and comparing objects and we address the problem of generating appropriate copying and comparing operations automatically, a service that is not provided by most object oriented languages and environments. Automatic generatio...
