Subject Re: CFP: Workshop on Open Infrastructures and Analysis Frameworks for HLT
Date Fri, 15 Aug 2014 05:56:47 GMT
The workshop program, along with links to the full papers, is now
available: http://glicom.upf.edu/OIAF4HLT/Program.html

I'm looking forward to seeing many of you there.  I'll be staying at DCU
(College Park).

>> and support it. To this end, the workshop will include both presentations

>> discussion that will identify next steps for moving forward, fostering
>> community-wide awareness, and establishing and encouraging communication
>> among the various players.

>> such platforms for modern, well-engineered NLP applications.

>> ### Topics
>> Workshop topics include, but are not limited to:
>> - processing of very large data collections: scale-out, parallelization,
>> and performance optimization
>> - advanced applications driven by an NLP framework
>> - sophisticated tools to build and manage complex processing pipelines
>> - analysis of results: exploration, evaluation, visualization, and
>> statistical analysis
>> - experience reports combining components from different sources, as well
>> as solutions to interoperability issues
>> - experience reports combining different frameworks (e.g.
>> GATE/UIMA/WebLicht/etc.)
>> - UIMA components with a special focus on genericity and type-system
>> independence
>> - repositories of ready-to-use components for UIMA and/or GATE
>> - distribution of components: documentation, licensing and packaging
>> - developing for UIMA or GATE: simplified APIs, debugging, unit testing,
>> and limitations of the frameworks
>> - combining annotation type systems in processing frameworks (GATE, UIMA,
>> etc.) with standardization efforts, such as done in the ISO TC37/SC4 or TEI
>> contexts.
>> - use of NLP frameworks in real-world "industry" settings
>> - reports on current projects and frameworks, their challenges and
>> proposed or implemented solutions, including efforts to address
>> interoperability
>> - issues and challenges of multi-site collaborative projects, including
>> reports of implemented or proposed strategies
>> - pipeline management, including authentication, strategies for passing
>> resources through disparate tools and across hosting nodes, and licensing
>> - development and use of evaluation environments that facilitate
>> assessment of HLT component performance, iterative application development,
>> and replication of results
>> - community awareness and implementation of open infrastructures,
>> including how to engage the community, establish confidence in the process,
>> and promote use
