Top-level domain crawling for producing comprehensive monolingual corpora from the web

This paper describes crawling and corpus processing in a distributed framework.

We present new tools that build upon existing tools like Heritrix and Hadoop. Further, we propose a general workflow for harvesting, cleaning and processing web data from entire top-level domains in order to produce high-quality monolingual corpora using the least amount of language-specific data. We demonstrate the utility of the infrastructure by producing corpora for two under-resourced languages. Web corpus production for targeted languages and/or domains thus becomes feasible for anyone.
