== It takes an awful long time to parse one simple sentence. Why? ==

It is because the parser needs to load the model which is very time consuming.
There are two ways around this. You can give the parser a file with many sentences so it only has to load the model once. Or you can use the parser in server mode (with SOAP). 

== I don't get a parse for this simple sentence which is in the input file. What's wrong? ==

Check whether the input file has a new line after the sentence you want to parse. The parser expects each sentence on a line followed by a new line. 

== I get the following error when trying to run bin/parser: ==
{{{
parser:could not open model configuration file for reading:../models/parser//config
}}}
This is a bug in version 1.00 of the models. To fix it just create an empty configuration file in the parser model directory:
{{{
touch models/parser/config
}}}

== Can the parser output more than one analysis? ==

No. The current version of the parser is only able to output the highest scoring analysis. This may change in future versions.

== Does the parser do any tokenisation or sentence boundary detection? ==

Currently no. So it's important that the input fed to the parser consists of a single sentence per line tokenised according to the Penn Treebank standard (details of which are on the Penn Treebank website).

== Can the parser output more than one output format (eg CCG dependencies and Grammatical Relations) at the same time? ==

Currently no.

== Where can I find out what the various CCG categories mean? ==

The CCG pages contain links to a number of publications on CCG, including tutorial papers: http://groups.inf.ed.ac.uk/ccg/publications.html

== What do the various features on the S categories mean, such as [dcl]? ==

Look at Julia Hockenmaier's thesis, available from the above web page.
