OneClick Dictionary (OCD) is a dictionary drafting module. It interconnects a corpus management system (e.g. SketchEngine, noSketch Engine) or even excel sheets with our dictionary writing and online dictionary publishing system Lexonomy and provides an automatically created dictionary draft (e.g. headwords, wordforms, collocations, examples), to be post-edited in Lexonomy by the lexicographer. OneClick Dictionary enables lexicographers to shift all lexicographers work and intellectual input into the post-editing phase instead of manually analyzing the input data before creating a dictionary draft. Hence, the tool is not limited to professionals but also designed for spontaneous lexicography – small projects of lexicographic nature such as glossaries and domain-specific wordlists and dictionaries often prepared by teachers or other professionals without formal training in lexicography. The source code for the OneClick Dictionary module is available on Github, additional information is available in the Deliverable 4.2:
