Special Topic

Interoperability of corpus query and analysis systems


Large corpora require careful design, licensing, collecting, cleaning, encoding, annotation, management, storage, retrieval, analysis, and curation to unfold their potential for a wide range of research questions and users, across a number of disciplines. Apart from the usual CMLC topics that fall into these areas, CMLC-6 will have a special focus on corpus query and analysis systems and specifically on goals concerning their interoperability.

In the past 5 years, a whole new generation of corpus query engines that overcome limitations on the number of tokens and annotation layers has started to emerge at several different places. While there seems to be a consensus that there can be no single corpus tool that fulfills the need of all communities and that a degree of heterogeneity is required, the time seems ripe to discuss whether (further, unrestricted) divergence should be avoided in order to allow for some interoperability and reusability – and how this can be achieved. The two most prominent areas where interoperability seems highly desirable are query languages and software components for corpus analysis. The former issue is already partially addressed by the proposed ISO standard Corpus Query Lingua Franca (CQLF). Components for corpus analysis, on the other hand, should in an ideal world be exchangeable and reusable across different platforms, not only to avoid redundancies, but also to foster replicability and a canonization of methodology in NLP and corpus linguistics.

The 6th edition of the workshop will devote much of its time to these issues, including an expert panel discussion with representatives of tool development teams and power users.

Important dates

Identify, Describe and Share your LRs!

Describing your LRs in the LRE Map is now a normal practice in the submission procedure of LREC (introduced in 2010 and adopted by other conferences). To continue the efforts initiated at LREC 2014 about “Sharing LRs” (data, tools, web-services, etc.), authors will have the possibility, when submitting a paper, to upload LRs in a special LREC repository. This effort of sharing LRs, linked to the LRE Map for their description, may become a new “regular” feature for conferences in our field, thus contributing to creating a common repository where everyone can deposit and share data.

As scientific work requires accurate citations of referenced work so as to allow the community to understand the whole context and also replicate the experiments conducted by other researchers, LREC 2018 endorses the need to uniquely Identify LRs through the use of the International Standard Language Resource Number (ISLRN, www.islrn.org), a Persistent Unique Identifier to be assigned to each Language Resource. The assignment of ISLRNs to LRs cited in LREC papers will be offered at submission time.
