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 
othersí 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 
- 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 domains)
- 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 (http://www.lrec-conf.org/lrec2012/).
To submit contributions, please follow the instructions at 
The 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 information on this new 
initiative, please refer to:
