Text mining and the need for visualisation
Beatrice Alex / Education, Edinburgh
Thursday 25th October 4pm T-Room, 1st Floor Evolution House
There are large textual data collections available for research but how are you able to find what you are looking for? Having access to data does not mean you can use it. This is the case with many archives where a wealth of knowledge remains hidden. This talk will focus on text mining, a natural language processing technology which detects nuggets of information by turning unstructured raw text into structured information. The presentation will provide examples of my work on text mining when applied to different domains and types of text, ranging from historical documents to literary works and healthcare records. It will also present the research I am proposing to do as part of my Chancellor’s Fellowship where my focus will be directed partly to mining transcripts of audio and video archives. The presentation will show examples of how text mining output benefits from information visualisation to aid discovery.
