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). {{{#!comment === Registration === Participants should register for an ACL package that includes WAC-X.

We strongly recommend the use of the ACL 2016 LaTeX style files or Microsoft Word Style files. We reserve the right to reject submissions that do not conform to these styles including font and page size restrictions. '''Note: Unfortunately, the ACL have not released a Word template for ACL 2016. Below is the link to the template from 2015. If you submit in Word format and your paper is accepted, you will have to make sure that your final submission conforms to the ACL 2016 guidelines in order for it to appear in the proceedings.''' This should be fairly easy, however. * [http://acl2016.org/files/acl2016.zip "Download ACL 2016 LaTeX style file package here"] (or from [http://acl2016.org/index.php?article_id=9]) * [http://acl2015.org/files/acl2015.dot "Download ACL 2015 Word template here"] (or from [http://acl2015.org/call_for_papers.html]) Full paper submissions may consist of up to eight (8) pages of content plus any number of pages consisting of only references. Short papers may consist of up to four (4) pages of content plus any number of pages consisting of only references. Full papers will be distinguished from short papers in the proceedings. Papers will be presented either orally or as posters at the workshop. There will be no distinction between papers presented orally and those presented as posters in the proceedings. Reviewing of papers will be double-blind. Therefore, the paper must not include the author's names and affiliations. Furthermore, self-references that reveal the author's identity, e.g., "We previously showed (Smith, 1991) ...", must be avoided. Instead, use citations such as "Smith (1991) previously showed ...". Papers not conforming to these requirements will be rejected without review. }}} === Program committee === The workshop organizers were not part of the program committee. * Adrien Barbaresi, ÖAW (AT) * Silvia Bernardini, University of Bologna (IT) * Douglas Biber, Northern Arizona University (US) * Felix Bildhauer, Institut für Deutsche Sprache Mannheim (DE) * Katrien Depuydt, INL, Leiden (NL) * Jesse de Does, INL, Leiden (NL) * Cédrick Fairon, UC Louvain (BE) * William H.

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. {{{#!comment === Panel discussion "Corpora, open science, and copyright reforms" === #paneldisc As part of the 10th Web as Corpus workshop (WAC-X), a panel discussion will be organized. Web cor­pus designers are probably those who are most affected by issues and uncertainties of copyright legisla­tion and intellectual property rights, especially in the EU. While in some countries, such as the U.S., a Fair Use doctrine allows the use of data for non-commercial research purposes, the situation in Europe is more problematic. For example, German copyright law ("Urheberrecht") requires that any re-use of a work which reaches a certain threshold of creativity be explicitly approved by the author. This poses numerous problems for any corpus creator, but it is completely infeasible for large web corpora con­taining texts written by millions of different authors. Thus, corpora are re-distributed in crippled form as sentence shuffles (e.g. COW and the Leipzig Corpora Collection), and it is not even clear whether there really is a reliable legal exemption for single sentences. In the famous Infopaq case, a Danish court decided that even snippets of 11 words might be protected under EU copyright laws (http://bit.ly/1GYTDjR). This situation is highly unsatisfactory. Large web corpora have been shown to be indispensable for many tasks in computational linguistics, in the documentation of standard and non-standard language, and in empirically oriented theoretical linguistics. Reports written by legal experts – such as the one recently commissioned by the German Research Council (http://bit.ly/1PG4Gq6) – only provide an interpretation of the given legal situation. Only ac­tive lobbying in favor of a reasonable copyright reform will eventually bring about the necessary changes such that researchers can build corpus resources and share them freely for academic purposes. Therefore, the goal of this panel discussion is to bring together corpus creators, active users of web cor­pora, and open science activists in order to share and discuss views on the copyright problem as a politi­cal rather than a legal problem. Ideally, a first draft of a joint declaration might come out of this discussion. With such a declaration, the (web) corpus community could make sure that its voice is heard, especially in the ongoing discussion about reforms of the European copyright legislation. }}}
