\maketitle

This paper overviews publications connected to the language resources 
produced in the MULTEXT-East project or its follow-ups:

There are so far four overview papers on MULTEXT-East: the project was
presented at the outset in \cite{Erj:TihMTE}, and at its completion in
\cite{coling98:mte}. The second vesion of the resources the ``Concede
Edition'' was presented in \cite{mte:nlprs}. The current, third
version, bringing together the first two is published in
\cite{mte-lrec04}, and a copy of the paper is available at
%html is one dir deeper..
\htmladdnormallink{mte-lrec2004.pdf}{../mte-lrec2004.pdf}.

In the context of overview papers we should also mention
\cite{coling94:mt}, as the most widely cited paper about MULTEXT.

Various aspects of the project at completion were presented at the
LREC'98 conference: \cite{lrec98:mtecorp} dealt with the MULTEXT-East
corpus, and \cite{lrec98:mtelex} with the lexicon, while
\cite{lrec98:mtecd} introduced the double CD-ROM published by TELRI,
one volume of which contained the extended MULTEXT-East deliverables.
At the same conference, the Corpus Encoding Standard, CES, the
encoding of the MULTEXT-East corpora, was also presented
\cite{lrec98:ces}.

The details of the project are explained in three MULTEXT-East
deliverable reports, all available on the WWW. The most substantive
one is report D1.1F ``Specifications and Notation for Lexicon
Encoding'', \cite{MTE:D11F}. This report has been substantially
revised and expanded in the subsequent editions of the MULTEXT-East
deliverables. In particular, version 2 was presented in
\cite{mte:nlprs}, and version 3 in \cite{mte:slav}.

The other two reports of MULTEXT-East were MTE:D21F Corpus Collection
and Preparation \cite{MTE:D21F} and the MTE:D23F Corpus Markup
\cite{MTE:D23F}.  Two reports of the MULTEXT project also
substantially influenced the work in MULTEXT-East, namely the report
on the MtSeg tool \cite{mt:mtseg} and the MULTEXT specifications for
lexicon encoding, \cite{mt:D161B}.

The project's morphosyntactically annotated '1984' novel represented
the first tagged and available corpus for most languages involved in
the project; at the same time, language independent taggers were
becoming available. It is therefore not surprising that the most use
was made of the Orwell corpus as a dataset for experiments in tagging
models. An experiment that uses most of the multilingual corpus is
\cite{anlp00:hajic}. The other research concentrates on particular
MULTEXT-East languages, and has mostly been presented at the LREC'00
conference. Tagging Romanian has been studied in \cite{lnia99:tufis}
and \cite{lrec00:tufis}, Hungarian in \cite{lrec00:tufisetal} and
Slovene in \cite{lrec00:dzeroskietal}, the latter based on the more
substantial report \cite{dzerza99}.

A similar strand of research into learning tagging or morphological
modules has also used the MULTEXT-East corpus and lexicon. But here the
methods are less statistical and fall more into the Machine Learning
paradigm. A series of WWW sites has been set up, dubbed ``Learning
Language in Logic'' that also contain bibliographies related to
learning from MULTEXT-East data. Inductive Learning of Multilingual
Morphology was presented in \cite{er98} and \cite{ManDzeErj:Clog}.
Learning to tag Slovene is discussed in \cite{cussens99:_morph} and
learning word segmentation rules for tag prediction in
\cite{kazakov99:_learn}. Tagging Hungarian was also studied in the
context of LLL and using MULTEXT-East data; details are given in
\cite{Alexin98-WAGA99:proc,Horvath99-ILP99:proc}.

One of the aims of the EU Concede project was to integrate the corpus
results of MULTEXT-East with lexical databases. The initial dictionary
headwords were sampled from the corpus \cite{complex99:cnc}, and a
summary of preliminary results, along with a integration of the
Concede English-Slovene sample with the MULTEXT-East corpus was
presented in \cite{lrec00:cnc}. The final results were presented in
\cite{cnc-complex03}.

The parallel corpus was used in experiments in automatic bi-lingual
lexicon extraction; the work on Romanian-English was presented in
\cite{tufis:eq01}, in (D. Tufis et al. ALC-ACH 2001), and in Journal
of Science and Technology of Information, in print.

The '1984' corpus was also used on another strand of research in which
discusses cross-lingual sense determination and was published in
\cite{ide00:wsd}, \cite{IdeErjTuf2001}, \cite{IdeErjTuf2002}.

Last, but not least, are the papers that discuss a particular language
in the scope of MULTEXT-East or utilising MULTEXT-East resources.  The
Czech '1984' was discussed in \cite{petkevic:orwl}.  A paper connected
to exploitation of the Romanian portion of the resources, in the
context of making a Web-based corpus server is \cite{lrec00:bohus}.
The Slovene MULTEXT-East lexicon was presented in \cite{erk:mtelex},
and work on a platform using MULTEXT derived specifications for
Slovene in \cite{lrec00:rojckacic}. At the same conference, work on
Latvian was also reported \cite{lrec00:lat}. The Slovene
morphosyntactic specifications were subsequnelty used to annotate the
FIDA reference corpus of the Slovene language \cite{sdjt:fida}.

For most of the languages in question, the original MULTEXT-East
annotation work was a pioneering effort, so it was hardly surprising
that during use a number of errors and inconsistencies were discovered
in the data and specifications.  These errors were subsequently
corrected, but because the work was done at different sites and in
different manners, the corpus encodings had begun to drift apart.  The
EU project Concede (Consortium for Central European Dictionary
Encoding), \cite{lrec00:cnc} which ran from 1998 to 2000 and comprised
most of the same partners as MULTEXT-East, offered the possibility to
bring the versions back on a common footing. In the scope of a
workpackage of the project, the corrected ``1984'' corpus was
normalised and the primary data re-encoded according to the TEI (Text
Encoding Initiative) guidelines and, largely, to the XML
recommendation.  This second version is briefly described in
\cite{elsnews01:v2} and more fully in \cite{mte:nlprs}.

Finallly, Version 3 of the MULTEXT-East resources brought together
both previous versions (TELRI nad CONCEDE), and made them available in
XML, in TEI P4. A sampler corpus was first made from the CONCEDE
release, which served as one of the test cases for the TEI Task Force
on SGML to XML migration \cite{tei-migr:lrec02}. Then the complete
CONCEDE and TELRI coprus was converted from SGML to XML, and from TEI
P3 and CES respectivelly, to a uniform TEI P4, including the
documentation. Version 3 also added components for Serbian and Resian, 
and is described in \cite{mte-lrec04}, and a copy of the
paper available at
%html is one dir deeper..
