The lecture portion of the BASE corpus can be accessed through the corpus analysis interface, Sketch Engine. All 160 lectures are included, with 40 for each general disciplinary domain. This interface allows the user to view concordance lines, form complex queries, collect word frequency data (including word lists) and more. The service requires a subscription - for details, visit the Sketch Engine website at http://www.sketchengine.co.uk/. The service can be obtained initially on a 30 day trial subscription with full access to all resources.
