Abstract

Creating, curating and maintaining modern political corpora is becoming an ever more involved task. As interest from various socialbodies and the general public in political discourse grows so too does the need to enrich such datasets with metadata and linguisticannotations. Beyond this, such corpora must be easy to browse and search for linguists, social scientists, digital humanists and thegeneral public. We present our efforts to compile a linguistically annotated and semantically tagged version of the Hansard corpus from1803 right up to the present day. This involves combining multiple sources of documents and transcripts. We describe our toolchainfor tagging; using several existing tools that provide tokenisation, part-of-speech tagging and semantic annotations. We also provide anoverview of our bespoke web-based search interface built on LexiDB. In conclusion, we examine the completed corpus by looking atfour case studies making use of semantic categories made available by our toolchain.
