\begin{abstract}
  This document contains the instructions for preparing a camera-ready
  manuscript for the proceedings of NAACL-HLT Conferences. The
  document itself conforms to its own specifications, and is therefore
  an example of what your manuscript should look like.  Authors are
  asked to conform to all the directions reported in this document,
  both in preparing submissions to the conference and in preparing
  final camera-ready copy.
\end{abstract}

\section{Credits}

This document has been adapted from the instructions for ACL-02
proceedings by Eugene Charniak and Dekang Lin, which in turn was based
on the formats of earlier ACL and EACL Conference proceedings.
Those versions were written by several people, including
John Chen, Henry S. Thompson and Donald Walker. Additional elements
were taken from the formatting instructions of the {\em
  International Joint Conference on Artificial Intelligence}.

\section{Introduction}

The following instructions are directed to authors of papers submitted
to or accepted for publication in the NAACL-HLT Proceedings.  All
authors are required to adhere to these specifications. Authors are
required to provide a Portable Document Format (PDF) version of their
papers.  The proceedings will be printed on US-Letter paper.  Authors
from countries in which access to word-processing systems is limited
should contact the publication chairs for the meeting as soon as possible.

\section{General Instructions}

Manuscripts must be in two-column format.  Exceptions to the
two-column format include the title, authors' names and complete
addresses: \textbf{author information should be included only in final
camera ready copy, not in (blind) submissions.}  Title and (when
present) author information must be centered at the top of the first
page.  You may also deviate from the two-column format to include
full-width figures or tables (see the guidelines in
Subsection~\ref{ssec:first}).  \textbf{Type single-spaced.}  Start all
pages directly under the top margin.  See the guidelines later
regarding formatting the first page.

%% If the paper is produced by a printer, make sure that the quality
%% of the output is dark enough to photocopy well.  It may be necessary
%% to have your laser printer adjusted for this purpose.  Papers that are too
%% faint to reproduce well may not be included.

%% {\bf Do not print page numbers on the manuscript.}  Write them lightly
%% on the back of each page in the upper left corner along with the
%% (first) author's name.

For the main conference, the maximum length of a manuscript is eight
($8$) pages for full papers and four ($4$) pages for short and demo
papers, printed single-sided (see Section~\ref{sec:length} for
additional information on the maximum number of pages).

\subsection{Electronically-available resources}

ACL provides this description in \LaTeX2e{} (hlt-naacl06.tex) and PDF
format (naacl-hlt.pdf), along with the \LaTeX2e{} style file used to
format it (naacl-hlt.sty) and an ACL bibliography style (acl.bst).
These files are all available on the web; for example through the
conference web site.  (You can always find them with Google.)  A
Microsoft Word template file (\texttt{naacl-hlt.dot}) is also
available at the same URL. We strongly recommend the use of these
style files, which have been appropriately tailored for the NAACL-HLT
Proceedings.

\subsection{Format of Electronic Manuscript}
\label{sect:pdf}

For the production of the electronic manuscript you must use Adobe's
Portable Document Format (PDF). This format can be generated from
postscript files: on Unix systems, you can use {\tt ps2pdf} for this
purpose; under Microsoft Windows, you can use Adobe's Distiller, or
if you have cygwin installed, you can use \textit{dvipdf} or
\textit{ps2pdf}.  Note 
that some word processing programs generate PDF which may not include
all the necessary fonts (esp. tree diagrams, symbols). When you print
or create the PDF file, there is usually an option in your printer
setup to include none, all or just non-standard fonts.  Please make
sure that you select the option of including ALL the fonts.  {\em
  Before sending it, test your {\/\em PDF} by printing it from a
  computer different from the one where it was created}. Moreover,
some word processor may generate very large postscript/PDF files,
where each page is rendered as an image. Such images may reproduce
poorly.  In this case, try alternative ways to obtain the postscript
and/or PDF.  One way on some systems is to install a driver for a
postscript printer, send your document to the printer specifying
``Output to a file'', then convert the file to PDF.

For reasons of uniformity, Adobe's {\bf Times Roman} font should be
used. In \LaTeX2e{} this is accomplished by putting

\begin{quote}
\begin{verbatim}
\usepackage{times}
\usepackage{latexsym}
\end{verbatim}
\end{quote}
in the preamble.

\subsection{Layout}
\label{ssec:layout}

Format manuscripts two columns to a page, in the manner these
instructions are formatted. The exact dimensions for a page on US-letter
paper are:

\begin{itemize}
\item Left and right margins: 1in
\item Top margin:1in
\item Bottom margin: 1in
\item Column width: 3.15in
\item Column height: 9in
\item Gap between columns: 0.2in
\end{itemize}

Papers should not be submitted on any other paper size. It is of
utmost importance to specify the {\bf US-Letter format} (8.5in
$\times$ 11in) when formatting the paper.  When working with {\tt
  dvips}, for instance, one should specify {\tt -t letter}.

Print-outs of the PDF file on US-Letter paper should be identical to the
hardcopy version.  If you cannot meet the above requirements about the
production of your electronic submission, please contact the
publication chairs above  as soon as possible.

Exceptionally, authors for whom it is \emph{impossible} to format on
US-Letter paper, may format for \emph{A4} paper. In this case, they
should keep the \emph{top} and \emph{left} margins as given above, use
the same column width, height and gap, and modify the bottom and right
margins as necessary.  Note that the text will no longer be centered.

\subsection{The First Page}
\label{ssec:first}

Center the title---and for final copy only author's name(s) and
affiliation(s)---across both columns. Do not use footnotes for
affiliations.  Do not include the paper ID number assigned during the
submission process.  Use the two-column format only when you begin the
abstract.

{\bf Title}: Place the title centered at the top of the first page, in
a 15-point bold font. Long title should be typed on two lines without
a blank line intervening. Approximately, put the title at 1in from the
top of the page, followed by a blank line.  Then include either four
blank lines (submission version) or (camera ready version) the
author's names(s), with affiliation(s) on the following lines.  Do not
use only initials for given names (middle initials are allowed). The
affiliation should contain the author's complete address, and if
possible an electronic mail address. Leave about 0.75in between the
affiliation and the body of the first page.

{\bf Abstract}: Type the abstract at the beginning of the first
column.  The width of the abstract text should be smaller than the
width of the columns for the text in the body of the paper by about
0.25in on each side.  Center the word {\bf Abstract} in a 12 point
bold font above the body of the abstract. The abstract should be a
concise summary of the general thesis and conclusions of the paper.
It should be no longer than 200 words.

{\bf Text}: Begin typing the main body of the text immediately after
the abstract, observing the two-column format as shown in 
the present document.

{\bf Indent} when starting a new paragraph. For reasons of uniformity,
use Adobe's {\bf Times Roman} fonts, with 11 points for text and 
subsection headings, 12 points for section headings and 15 points for
the title. If Times Roman is unavailable, use {\bf Computer Modern
  Roman} (\LaTeX2e{}'s default; see section \ref{sect:pdf} above).
Note that the latter is about 10\% less dense than Adobe's Times Roman
font.

\subsection{Sections}

{\bf Headings}: Type and label section and subsection headings in the
style shown on the present document.  Use numbered sections (Arabic
numerals) in order to facilitate cross references. Number subsections
with the section number and the subsection number separated by a dot,
in Arabic numerals. Do not number subsubsections.

{\bf Citations}: Citations within the text appear
in parentheses as~\cite{Gusfield:97} or, if the author's name appears in
the text itself, as Gusfield~\shortcite{Gusfield:97}. 
Append lowercase letters to the year in cases of ambiguities.  
Treat double authors as in~\cite{Aho:72}, but write as 
in~\cite{Chandra:81} when more than two authors are involved. 
Collapse multiple citations as in~\cite{Gusfield:97,Aho:72}.

\textbf{References}: Gather the full set of references together under
the heading {\bf References}; place the section before any Appendices,
unless they contain references. Arrange the references alphabetically
by first author, rather than by order of occurrence in the text.
Provide as complete a citation as possible, using a consistent format,
such as the one for {\em Computational Linguistics\/} or the one in the 
{\em Publication Manual of the American 
Psychological Association\/}~\cite{APA:83}.  Use of full names for
authors rather than initials is preferred.  A list of abbreviations
for common computer science journals can be found in the ACM 
{\em Computing Reviews\/}~\cite{ACM:83}.

The \LaTeX{} and Bib\TeX{} style files provided roughly fit the
American Psychological Association format, allowing regular citations, 
short citations and multiple citations as described above.

{\bf Appendices}: Appendices, if any, directly follow the text and the
references (but see above).  Letter them in sequence and provide an
informative title: {\bf Appendix A. Title of Appendix}.

\textbf{Acknowledgement} sections should go as a last section immediately
before the references.  Do not number the acknowledgement section.

\subsection{Footnotes}

{\bf Footnotes}: Put footnotes at the bottom of the page. They may
be numbered or referred to by asterisks or other
symbols.\footnote{This is how a footnote should appear.} Footnotes
should be separated from the text by a line.\footnote{Note the
line separating the footnotes from the text.}

\subsection{Graphics}

{\bf Illustrations}: Place figures, tables, and photographs in the
paper near where they are first discussed, rather than at the end, if
possible.  Wide illustrations may run across both columns. Do not use
color illustrations as they may reproduce poorly.

{\bf Captions}: Provide a caption for every illustration; number each one
sequentially in the form:  ``Figure 1. Caption of the Figure.'' ``Table 1.
Caption of the Table.''  Type the captions of the figures and 
tables below the body, using 11 point text.  


\section{Length of Submission}
\label{sec:length}

Eight pages ($8$) is the maximum length of full papers for the
NAACL-HLT main conference.  Short and demo papers for the main
conference have a maximum length of four ($4$) pages.  All
illustrations, references, and appendices must be accommodated within
these page limits, observing the formatting instructions given in the
present document.  Papers that do not conform to the specified length
and formatting requirements are subject to be rejected without review.

For accepted papers, it may be possible to purchase additional pages
from ACL.  Please contact the publication chairs for more information
about this option.
