In this video Dr. Derrick Cogburn introduces you to categorization models, a powerful deductive technique for text mining. These approaches help to identify the extent to which a specific concept is present or absent within a specific large-scale textual dataset. These categorization models can be relatively simple bifurcations of concepts, or require multiple levels and sub-levels supported by specific words, phrases and/or rules to help identify the specific content of interest. Dr. Cogburn teaches graduate seminars on Big Data Analytics and Text Mining (using ProSuite and R/Rstudio)He has coordinated multiple United Nations workshops/side events on text mining in international affairs, sustainable development goals (SDGs), and CRPD Implementation. Derrick has published multiple articles and conference papers on text mining.
