[eu_members at aclweb dot org] Colorado: NAACL HLT 2009 Workshop on Active Learning for Natural Language Processing -- Call for Participation



===================================================================

                      CALL FOR PARTICIPATION

===================================================================
                     NAACL HLT 2009 Workshop on
           Active Learning for Natural Language Processing


               June 5, 2009, Boulder, Colorado, USA
                   http://nlp.cs.byu.edu/alnlp/

      Endorsed by the following ACL Special Interest Groups:
     • Special Interest Group on Natural Language Learning (SIGNLL)
     • Special Interest Group for Annotation (SIGANN)

===================================================================

Labeled data is a prerequisite for many popular algorithms in natural
language processing and machine learning.  While it is possible to
obtain large amounts of annotated data for well-studied languages in
well-studied domains and well-studied problems, labeled data are rarely
available for less common languages, domains, or problems.
Unfortunately, obtaining human annotations for linguistic data is
labor-intensive and typically the costliest part of the acquisition of
an annotated corpus.

It has been shown before that active learning can be employed to reduce
annotation costs but not at the expense of quality.  While diverse work
over the past decade has demonstrated the possible advantages of active
learning for corpus annotation and NLP applications, active learning is
not widely used in many ongoing data annotation tasks.  Much of the
machine learning literature on the topic has focused on active learning
for classification problems with less attention devoted to the kinds of
problems encountered in NLP.

This workshop aims at bringing together researchers to explore the
challenges and opportunities of active learning for NLP tasks, language
acquisition, and language learning.
