*NLP4UGC 2012: "@NLP can u tag #user_generated_content?! via"*

           Workshop in conjunction with LREC 2012
           Istanbul, May 21 - 27 2012
           Workshop date: Saturday May 26 2012 (afternoon)
Submission deadline: February 15 2012

Background and Motivation

The Web 2.0 has transferred the authorship of contents from institutions
to the people; the web has become a channel where users exchange,
explain or write about their lives and interests, give opinions and rate
others' opinions. The so-called User Generated Content (UGC) in text
form is a valuable resource that can be exploited for many purposes,
such as cross-lingual information retrieval, opinion mining, enhanced
web search, social science analysis, intelligent advertising, and so on.
In order to mine the data from the Web 2.0 we first need to understand
its contents. Analysis of UG content is challenging because of its
casual language, with plenty of abbreviations, slang, domain specific
terms and, compared to published edited text, with a higher rate of
spelling and grammar errors. Standard NLP techniques, which are used to
analyze text and provide formal representations of surface data, have
been typically developed to deal with standard language and may not
yield the expected results on UGC. For example, shortened or misspelled
words, which are very frequent in the Web 2.0 informal style, increase
the variability in the forms for expressing a single concept.  This
workshop aims at providing a meeting point for researchers working in
the processing of UGC in textual form in one way or another, as well as
developers of UGC-based applications and technologies, both from
industry and academia.

_Topics of Interest_

We are mainly interested in, but not restricted to, the following
research questions:

- What characterises UGC? Linguistic and textual phenomena that
  distinguish UGC from standard written text, and may pose a challenge
  for NLP.

- Definition of norm, concept of error, deviation and variation in UGC.

- Criteria and standards for the annotation of evaluation corpora in UGC
  at various levels of linguistic analysis (form, part of speech,
  constituents, dependencies, speech acts, deviation types, etc.).

- How quality of text affects processing tasks (tokenization, POS
  tagging, chunking, parsing, named-entity detection, etc.)

- Architecture and software design for flexible adaptation of NLP
  processing pipelines to new domains (topic domains and text-genre

- Text normalisation vs adaptation of processing tools: - Pros and cons
  - Task dependent?  - Costs and benefits - Hybrid solutions

- Approaches to normalisation (text checking, ASR, MT techniques, etc.)

- Evaluation issues related to processing and normalising UGC- ...

Intended Audience

The workshop aims at bringing together researchers and developers from
academia and industry. In particular, perspectives from the following
user groups are welcome:

- UGC-based application developers, from both research and industry

- Researchers from the NLP, IR and IE communities- Ph.D students
  interested or working in the processing of UGC


Oral papers and posters should follow the main conference formatting
requirements ( To submit
contributions, please follow the instructions at contributions will undergo
a double review by members of the programme committee. When submitting a
paper from the START page, authors will be asked to provide essential
information about resources (in a broad sense, i.e. also technologies,
standards, evaluation kits, etc.) that have been used for the work
described in the paper or are a new result of your research. For further
