Abstract<br />
In recent years a development towards easier access to treebanks has been<br />
discernible. Fully onl<strong>in</strong>e environments for the creation, annotation and exploration<br />
<strong>of</strong> treebanks have however been very scarce so far. In this paper we<br />
describe some user needs from the annotator perspective and report on our experience<br />
with the development and practical use <strong>of</strong> a web-<strong>based</strong> annotation<br />
system.<br />
1 Introduction<br />
In the context <strong>of</strong> earlier semi-automated annotation projects, various annotation<br />
tools and <strong>in</strong>terfaces have been created and deployed. User <strong>in</strong>terfaces for efficient<br />
parse selection are described <strong>in</strong> the context <strong>of</strong> Alp<strong>in</strong>o [23] and L<strong>in</strong>go Redwoods<br />
[15], <strong>in</strong>spired by the TreeBanker [7]. Annotation tools for the Paris 7 French treebank<br />
were created as extensions <strong>of</strong> the Emacs editor and provide annotators with<br />
<strong>in</strong>teractive edit<strong>in</strong>g as well as visualization <strong>of</strong> trees [1]. Several graphical tree editors<br />
and viewers have been developed, such as the type check<strong>in</strong>g dependency tree editor<br />
TrEd, used for the Prague Dependency <strong>Treebank</strong> (PDT) [6, 11], the Annotate tool,<br />
used <strong>in</strong> Negra and Tiger [2, 3], and SALTO, which was developed for SALSA [5];<br />
the latter supports resolution <strong>of</strong> <strong>in</strong>ter-annotator disagreements. These tools require<br />
<strong>in</strong>stallation <strong>of</strong> applications on the client side which may be platform specific.<br />
New developments are oriented towards web-<strong>based</strong> <strong>in</strong>teraction. The Alp<strong>in</strong>o<br />
treebank [23] is browsable on the web with visualizations <strong>in</strong> SVG (Scalable Vector<br />
Graphics), but does not seem to <strong>of</strong>fer further onl<strong>in</strong>e functionality. The brat annotation<br />
system [22] is a web-<strong>based</strong> tool for text annotation which <strong>of</strong>fers a user-friendly<br />
web <strong>in</strong>terface for manual annotation and is very suitable for collaborative edit<strong>in</strong>g.
