Subject srl bug with one word sentences
Date Mon, 08 Apr 2013 19:53:32 GMT
I filed a jira (https://issues.apache.org/jira/browse/CTAKES-184) for an 
issue in the srl component of the dependency parser. Here is the issue: 
The SRL component grabs the Dependency Node for each token using the 
token span. When there is a one-word sentence there are two such nodes, 
the "head" node which spans the sentence and the token node. There is a 
quick fix checked in that looks at the "id" field, but it would be 
preferable to fix it upstream so that users of the Dependency types 
don't need to know about this issue.

Here are a few possibilities, any other ideas?
1) Change the span of the head node, maybe to 0 length at the start of 
the sentence?
2) Create a separate type for DependencyTreeHead, perhaps spanless
