LREC, the International Conference on Language Resources and Evaluation is a biennial conference organised by the European Language Resources Association with the support of institutions and organisations involved in Natural language processing. The series of LREC conferences was launched in Granada in 1998. Since then, LREC has become the major event on Language Resources (LRs) and Evaluation for Human Language Technologies (HLT). The aim of LREC is to provide an overview of the state-of-the-art, explore new R&D directions and emerging trends, exchange information regarding LRs and their applications, evaluation methodologies and tools, ongoing and planned activities, industrial uses and needs, requirements coming from the e-society, both with respect to policy issues and to technological and organisational ones.

Conference Topics[edit]

The following topics covered at the latest conferences are:

  • Semantics and Knowledge, in all its variations, from annotation of anaphoric, temporal, spatial information, to ontologies and lexicons, to disambiguation, named entities recognition, information extraction, and so on.
  • Subjectivity, declined in various nuances: emotions, opinions, sentiments.
  • Machine translation and multilinguism.
  • Infrastructural initiatives, strategies, national and international projects that are of major interest, as usual inside the LREC community.
  • Lexicons and Corpora.
  • Tools and systems for text analysis at many levels.
  • Dialogue and discourse, with contributions from both the Speech and Text communities.
  • Speech and multimodal databases, tools and systems.
  • Evaluation and validation methodologies, as a topic per se.
  • Language coverage and diversity, Less Resourced languages, Endangered languages.
  • Open, linked and shared data and tools, Open and collaborative architectures.
  • Sign language, multimedia information and multimodal communication

The LREC Map[edit]

The LREC Map has been introduced at LREC 2010 and finds its place within the infrastructural actions. While submitting their paper(s), the authors were asked to provide some basic information about all the resources (in a broad sense, i.e. including tools, standards and evaluation packages), either used or created, described in their papers. All these descriptors were then gathered in a global matrix called the LREC Map.
This feature has been extended to several other conferences to form the LRE Map.[1]

The Language Library[edit]

The Language Library [2] has been introduced at LREC 2012. The rationale behind this initiative is that accumulation of massive amounts of multi-dimensional data about language is the key to foster advancement in our knowledge about language and its mechanisms. The objective is to gather and share part of the linguistic knowledge the field is able to produce, starting a movement aimed at collecting all possible annotations/encodings at all possible levels. As a first experiment of a community-built repository that allows sharing of multidimensional and multi-level processed/annotated resources, it needs a small effort from each of you to put into place new ways of collaboration within the language resources and technology community.

History of conferences[edit]

The survey of the LREC conferences over the period 1998-2013 has been presented during the 2014 conference in Reykjavik as a closing session.[3] It appears that the number of papers and signatures is increasing over time. The average number of authors per paper is highier too. The percentage of new authors is between 68% and 78%. The distribution between male (65%) and female (35%) authors is stable over time. The most frequent technical term is "annotation", then comes "part-of-speech".
