Omorfi - Free and open source morphological lexical database for Finnish

This demonstration presents a freely available open source lexical database omorfi. Omorfi is a mature lexicographical database project, started out as a single-person single-purpose free open source morphological analyser project, omorfi has since grown to be used in variety of applications including spell-checking, statistical and rule-based machine translation, treebanking, joint syntactic and morphological parsing, poetry generation, information extraction. In this demonstration we hope to show both the variety of end-user facing applications as well as the tools and interfaces for computational linguists to make the best use of a developing product. We show a shallow database arrangement that has allowed a great variety of contributors from different projects to extend the lexical database while not breaking the continued use of existing end-applications. We hope to show both the best current practices for lexical data management and software engineering with regards to continuous external project integration of a constantly developing product. As case examples we show some of the integrations with following applications: Voikko spell-checking for Windows, Mac OS X, Linux and Android, statistical machine translation pipelines with moses, rule-based machine translation with apertium and traditional xerox style morphological analysis and generation. morphological segmentation, as well as application programming interfaces for python and Java.
