LREC-2012 Workshop (22 May 2012)

Challenges in the management of large corpora

We live in an age where the well-known maxim that “the only thing better than data is more data” is something that no longer sets unattainable goals. Creating extremely large corpora is no longer a challenge, given the proven methods that lie behind e.g. applying the Web-as-Corpus approach or utilizing Google's n-gram collection. Indeed, the challenge is now shifted towards dealing with the large amounts of primary data and much larger amounts of annotation data. On the one hand, this challenge concerns finding new (corpus-) linguistic methodologies that can make use of such extremely large corpora e.g. in order to investigate rare phenomena involving multiple lexical items or to find and represent fine-grained sub-regularities; on the other hand, some fundamental technical methods and strategies are being called into question. These include e.g. successful curation of the data, management of collections that span multiple volumes or that are distributed across several centres, methods to clean the data from non-linguistic intrusions or duplicates, as well as automatic annotation methods or innovative corpus architectures that maximise the usefulness of data or allow to search and to analyze it efficiently. Among the new tasks are also collaborative manual annotation and methods to manage it as well as new challenges to the statistical analysis of such data and metadata.

The half-day workshop on “Challenges in the management of large corpora” aims at gathering the leading researchers in the field of Language Resource creation and Corpus Linguistics, in order to provide for an intensive exchange of expertise, results and ideas.
