% Title: nlprs01.sty
% This is the LaTeX style file for NLPRS-2001 camera-ready.
%
% It is adopted by Tatsunori Mori (mori@forest.eis.ynu.ac.jp)
% from the LaTeX style file for ACL-2001.
% The ACL-2001 style file is adopted by Norbert Reithinger (bert@dfki.de)
% for A4 sized paper. It is based on the LaTeX style file for NAACL-2001.
% It is adopted by Yaser Al-Onaizan (yaser@isi.edu) from the LaTex style
% file for COLING-ACL'98 submissions. The COLING-ACL'98 style is based on
% the aclap style, with an ID page from the aclsub style and some other
% slight modifications by George Foster.

% Here's a document template:
%
% \documentclass[11pt]{article}
% \usepackage{nlprs01}
% \title{Title}
% \author{...}                     % see below for possible formats
% \begin{document}
% \maketitle
% \begin{abstract}
%   Summary
% \end{abstract}
% \section{...}
%   :
% \bibliographystyle{acl}          % use acl.bst
% %...
% \bibliography{yourbiblio}
% \end{document}
%
% or for earlier versions of latex:
%
% \documentstyle[11pt,nlprs01]{article}
% \title{Title}
% % ... (as above)

% Here are some other things you might want to know:
%
% - Author formats
%   Author information can be set in various styles.
%
%   For several authors from the same institution:
%   \author{Author 1 \and ... \and Author n \\
%           Address line \\ ... \\ Address line}
%   if the names do not fit well on one line use
%           Author 1 \\ {\bf Author 2} \\ ... \\ {\bf Author n} \\
%
%   For authors from different institutions:
%   \author{Author 1 \\ Address line \\  ... \\ Address line
%           \And  ... \And
%           Author n \\ Address line \\ ... \\ Address line}
%
%   To start a separate "row" of authors use \AND, as in
%   \author{Author 1 \\ Address line \\  ... \\ Address line
%           \AND
%           Author 2 \\ Address line \\ ... \\ Address line \And
%           Author 3 \\ Address line \\ ... \\ Address line}
%
%   If the title and author information does not fit in the area allocated,
%   place \setlength\titlebox{<new height>} after \usepackage{nlprs},
%   where <new height> can be something larger than 2.0in
%
% - to have a figure or table span both columns, use \figure* or \table*
%
% - Citation formats
%   Three possible citation formats:
%   "\cite{...}"      produces a citation like "(Author, 1999)"
%   "\shortcite{...}" produces a citation like "(1999)"
%   "\newcite{...}"   produces a citation like "Author (1999)"
%   All three take an optional argument which can be used to add page
%   references, etc.:
%   "\newcite[1--6]{...}" produces a citation like "Author (1999, 1--6)"
%
% LaTeX will reort error(s) if you do not do all of these:
% - all of the "\category", "\keywords" and "\paperid"
%   fields must be supplied.
