BootCaT

• Bootstrapping Corpora and Terms• Translators– Know the language– Not domain experts– Can interpret domain terms but can’t guess them

• Instant domain corpus from the web• Marco Baroni and Silvia Bernardini (2004)

BootCaT method

• Piggyback on a search engine– Google, Yahoo, Bing

• Set of seed terms• Repeat– Take random 3 seeds– Send to search engine– Gather ‘search hits’ pages

• Remove, duplicates, find terms– Can iterate

WebBootCaT

• Web interface• Improved cleaning, duplicate removal• Integrated with corpus tool (Sketch Engine)
