Thus, users now have several new search facilities, such as faceted search and fuzzy textual search, they can now register, log in and store search bookmarks for further perusal. Moreover, the data model now includes the notion of paper and author, which allows for linking the resources to the scientific works. Also, users can now visualise author-provided field values and normalised values. The normalisation has been manual and enables a better grouping of the entries. Last but not least, provisions have been made towards linked open data (LOD) aspects, by exposing an RDF access point allowing to query on the authors, papers and resources. Finally, a complete technological overhaul of the whole application has been undertaken, especially in terms of the Web infrastructure and of the text search backend.

Introduction Initiated by ELRA and FlaReNet and introduced at LREC 2010, the LRE Map is a new mechanism intended to moni- tor the use and creation of language resources by collecting information on both existing and newly-created resources during the process of submitting articles to conferences. It is a collective enterprise of the LREC community, as a first step towards the creation of a very broad, community- built, Open Resource Infrastructure. It is meant to become an essential instrument to monitor the field and to identify shifts in the production, use, and evaluation of LRs and LTs over the years. At LREC 2010, nearly 2000 language resource forms have been filled in. Apart from providing a portrait of the re- sources behind the community, of their uses and usabil- ity, the LRE Map intends to be a measuring instrument for monitoring the field of language resources. The feature has been so successful that it has been imple- mented also at COLING 2010, EMNLP 2010 and many other conferences, while other major events are in the pipeline, in addition to the LRE Journal. Since the LRE Map service has been set up, several new developments have been made. These developments are mostly concentrated in three direc- tions: 1. Upgrades of the Web platform 2. Extensions to the database model 3. Cleanup and normalization of the data The present paper documents the evolution of the LRE Map with respect to these directions. 2. LRE Map Platform Update The LRE Map Platform Upgrading has been undertaken by ELDA and consisted of the following actions: Figure 1: The new LRE Map Application. • The web platform technology has been migrated from a PHP/MySQL solution to a more modern Python/Django solution, backed by …
