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

                June 5, 2009, Boulder, Colorado, USA

                      http://nlp.cs.byu.edu/alnlp/

          ** Submission Deadline: EXTENDED TO March 10, 2009 **

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

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


MOTIVATION

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.


TOPICS

We are interested in bringing together researchers to explore the
challenges and opportunities of active learning for NLP tasks, language
acquisition, and language learning.  General work on active learning on
NLP classification tasks, sequence labeling, parsing, semantics, and
other more complex tasks will be welcome in the workshop.  More specific
topics of interest include, but are not limited to:

    - theoretical analysis of active learning in the context of NLP
      applications
    - novel active learning approaches to estimate the training utility
      of individual selection units
    - cost-sensitive active learning approaches incorporating data
      acquisition costs
    - approaches to model or predict annotation costs as well as studies
      on factors that influence annotation time
    - criteria for stopping or monitoring progress of active learning
    - overfitting of data acquired with active learning: how much is the
      data biased towards the learning scheme involved in the selection
      and what are the limitations of re-use with other learning schemes
    - Human-Computer Interaction aspects of annotation including
      requirements, impact of interface design on annotation time, and
      methods to deal with reliability of annotators
    - approaches to multi-task active learning
    - approaches to deal with or reduce computational complexity of
      active learning approaches including parallelization, issues of
      pool- or batch-size, varying degrees of look-ahead, etc.
    - active learning and domain adaption
    - active learning compared to or combined with other semi-supervised
      or even unsupervised learning approaches
    - application of active learning in real annotation projects and
      experiences gained thereby


SUBMISSIONS

We invite submissions of two kinds:
1. original and unpublished work as full papers, limited to 8 pages of
text (up to one extra page may be used for references);
2. position papers or papers describing ongoing work as short papers,
limited to 4 pages in total (including references).

Both kinds of papers will appear in the proceedings and will be
presented orally.  As reviewing will be double-blind, author information
should not be included in the papers and self-reference should be avoided.

All submissions must be made in PDF format using the START paper
submission website:
https://www.softconf.com/naacl-hlt09/ActiveLearningNLP2009/

Submissions must follow the NAACL HLT 2009 formatting requirements:
http://clear.colorado.edu/NAACLHLT2009/stylefiles.html

Authors are strongly encouraged to use the LaTeX or Microsoft Word style
files available there.  Papers not conforming to these requirements are
subject to rejection without review.
