A standardized general framework for encoding and exchange of corpus annotations: The Linguistic Annotation Framework, LAF

Kerstin Eckart; Proceedings of KONVENS 2012 (SFLR 2012 workshop), pp. 506-515, September 2012.


The Linguistic Annotation Framework, LAF, proposes a generic data model for exchange of linguistic annotations and has recently become an ISO standard (ISO 24612:2012). This paper describes some aspects of LAF, its XML-serialization GrAF and some use-cases related to the framework. While GrAF has already been used as exchange format for corpora with several annotation layers, such as MASC and OANC the generic LAF data model also proved useful as the basis for the design of data structures for a relational database management system.
