WAC-X main workshop

The World Wide Web has become increasingly popular as a source of linguistic data, not only within the NLP communities, but also with theoretical linguists facing problems of data sparseness or data diversity. Accordingly, web corpora continue to gain importance, given their size and diversity in terms of genres/text types. The field is still new, though, and a number of issues in web corpus construction need much additional research, both fundamental and applied. These issues range from questions of corpus design (e.g., assessment of corpus composition, sampling strategies and their relation to crawling algorithms, and handling of duplicated material) to more technical aspects (e.g., efficient implementation of individual post-processing steps in document cleaning and linguistic annotation, or large-scale parallelization to achieve web-scale corpus construction). Similarly, the systematic evaluation of web corpora, for example in the form of task-based comparisons to traditional corpora, has only recently shifted into focus. For almost a decade, the ACL SIGWAC (http://www.sigwac.org.uk/), and especially the highly successful Web as Corpus (WAC) workshops have served as a platform for researchers interested in compilation, processing and application of web-derived corpora. Past workshops were co-located with major conferences on computational linguistics and/or corpus linguistics (such as EACL, NAACL, LREC, WWW, and Corpus Linguistics).

WAC-X will also feature the final workshop of the EmpiriST 2015 shared task "Automatic Linguistic Annotation of Computer-Mediated Communication / Social Media" (see https://sites.google.com/site/empirist2015/ for details) and the panel discussion "Corpora, open science, and copyright reforms" (see https://www.sigwac.org.uk/wiki/WAC-X#paneldisc for details).

EmpiriST 2015 shared task

The EmpiriST 2015 shared task aims to encourage the developers of NLP applications to adapt their tools and resources to the processing of German discourse in genres of computer-mediated communica­tion (CMC), including both dialogical (chat, SMS, social networks, etc.) and monological (web pages, blogs, etc.) texts. Since there has been relatively little work in this area for German so far, the shared task focuses on tokenization and part-of-speech tagging as the core annotation steps required by virtu­ally all NLP applications. While we have a particular interest in robust tools that can be applied to dia­logical CMC and web corpora alike, participants are allowed to use different systems for the two sub­sets or submit results for one subset only. A substantial number of teams from German-speaking countries have already expressed their interest to participate in EmpiriST 2015. Knowledge of German is not essential for participation, though, since there are sufficient amounts of manually annotated training data (at least 10,000 tokens) and key docu­ments are provided in English.

The final workshop of EmpiriST 2015 will be co-located with WAC-X. It will include a detailed pre­sentation of the task and results, a poster session with all participating systems, oral presentations of se­lected systems, and a plenary discussion about the challenges of CMC in general as well as German CMC genres in particular.
