Old Bailey Data Warehousing Interface is a "proof-of-concept tool that enables users to quickly and easily visualize trends and distributions within the vast amount of information held within the Old Bailey Proceedings". Users set parameters and select sub categories in order to appropriately narrow the results of their search. Crime details can be filtered by offence, verdict, punishment, gender, and date. In addition, users can add specific word searches to pull records in which certain vocabulary appears. Once the search has been appropriately restrained the warehousing interface uses Python scripts to generate results to the Google Chart API. The data is finally presented as a matrix, concordance, dygraph, or word count dependent on the selection of the user.
