Annotation

After the completion of the POS-tagged corpus (see LOB background and history), the LOB Corpus has subsequently (since 1998) been re-tagged by Nicholas Smith and Geoffrey Leech at Lancaster University, using the enriched C7 and C8 tagsets, and identical POS-tagging has also been applied to three other comparable corpora, the Brown Corpus (American English, 1961), the FLOB Corpus (British English, 1991) and the Frown Corpus (American English, 1992): see Associated Projects above. These newly tagged versions of the four corpora are being distributed by ICAME and the Oxford Text Archive, enabling grammatical comparisons between the four corpora to be made on a comparable footing. (The newly-tagged Brown Corpus has not yet been post-edited.) The tagging and detailed comparison of the four corpora has been supported by grants from the Arts and Humanities Research Board (AHRB, now AHRC), the Leverhulme Trust, the British Academy and Deutsche Forschungsgemeinschaft (DFG). This work has been undertaken in collaboration with Christian Mair ( Freiburg University) and Marianne Hundt (formerly of Freiburg University, now of Zürich University), who were responsible for the compilation of the FLOB and Frown Corpora, and also for the post-editing of the automatic tagging undertaken at Lancaster.
