Tools to Create, Modify and Manage 'CWB' Corpora

The 'Corpus Workbench' ('CWB', <>) offers a classic and mature approach for working with large, linguistically and structurally annotated corpora. The 'CWB' is memory efficient and its design makes running queries fast (Evert and Hardie 2011, <>). The 'cwbtools' package offers pure R tools to create indexed corpus files as well as high-level wrappers for the original C implementation of CWB as exposed by the 'RcppCWB' package <>. Additional functionality to add and modify annotations of corpora from within R makes working with CWB indexed corpora much more flexible and convenient. The 'cwbtools' package in combination with the R packages 'RcppCWB' (<>) and 'polmineR' (<>) offers a lightweight infrastructure to support the combination of quantitative and qualitative approaches for working with textual data.
