This workshop is intended to commemorate the 50th anniversary of the ACL by creating a new space for debating and discussing about specific issues related to preserving, analysing and exploiting the scientific heritage of the ACL, as well as to envisage future trends, applications and research in Computational Linguistics. This workshop will be held during the main conference of ACL 2012. It will be free for participation to all ACL 2012 participants.

The main objective of the workshop is to gather contributions about the history, the evolution and the future of research in Computational Linguistics. Although this call for papers is open to any kind of technical contributions that are relevant to the main objective of the workshop, we specially encourage interested parties to submit research work related to the application of natural language processing and text mining techniques to the ACL Anthology Reference Corpus, which is publicly available from the ACL ARC project website: http://acl-arc.comp.nus.edu.sg/.

In addition to the technical program, the workshop will host a contributed-task, in the spirit of a crowd-sourcing activity, for augmenting and improving the current status of the ACL data collection. This contributed-task includes both, the format conversion of the most recent papers from pdf to rich-text format, and the processing, post-edition, correction and segmentation of the available digital versions of very old proceedings.

Technical contributions are to be organized into two tracks. The first track will consider review and discussion papers on the history and future of Computational Linguistics. The second track will consider reports about empirical work conducted over the ACL Anthology Reference Corpus or any other similar data collection. Topics of interest include, but are not limited to:

Review and discussion papers:
• History and evolution of Computational Linguistics
• Different approaches and paradigms for language analysis
• Current and future trends on Computational Linguistics
• Reviews on seminal papers and other milestone contributions
• The role of Computational Linguistics in the information society
• Uses and applications of Computational Linguistics
Empirical work papers:
• Sentiment analysis
• Information extraction
• Information retrieval
• Topic detection and tracking
• Plagiarism detection
• Authorship attribution
• Citation classification
• Social network analysis
• Discourse analysis
• Automatic summarization
• Text categorization
• Question answering

All submissions must be done electronically via the portal https://www.softconf.com/acl2012/R50/ and should follow the ACL 2012 format, as specified in http://acl2012.org/call/sub01.asp. The paper selection will follow a standard double-blind reviewing process, so submissions must not include author names, affiliations or self-references. Accepted papers will be presented at the workshop and published in the ACL 2012 workshop proceedings.
