Algorithms for the Thematic Analysis of Twitter Datasets Twitter: aneesha Email: aneesha.bakharia@gmail.com #comtech2011 Twitter Workshop Presented by: Aneesha Bakharia
Background ,[object Object],[object Object],[object Object],Surveys Workshops Interviews Large Doc Collections Corpus Twitter Blog Comments
Types of Qualitative Content Analysis (Hsieh and Shannon, 2006) Concentrate on Summative and Conventional (Inductive) Coding Approach Study Begins With Derivation of Codes Algorithms Summative Keywords Keywords identified before and during analysis Unsupervised and semi-supervised algorithms: NMF , NTF LDA and traditional clustering algorithms. Conventional (Inductive) Observation Categories developed during analysis Directed (Deductive) Theory Categories derived from pre-existing theory prior to analysis Supervised classification algorithms: Support Vector Machines
