dc.description.abstractAI-GENERATED ABSTRACT: Abstract: Few businesses operate in todays' environment without planned and purposeful Enterprise Architecture (EA). As organizations continue to transform and move toward digital, EAs must work with the business to define priorities and align business requirements to IT strategies. Utilizing the outcomes of Koc and others (2021), this paper will use topic modeling to identify, analyze, and report patterns within a dataset (Gillies and others, 2022). This study investigates the application of topic modeling techniques to analyze the goals and priorities of enterprise architects. The analysis below employs LDA, CTM, and BTM models, but there are other topic modeling techniques that could be explored in future research, such as Hierarchical Dirichlet Process (HDP) or Structural Topic Model (STM). Findings from this study provide a foundation for future research and further refinement of topic modeling techniques. Keywords: Enterprise Architecture, digital transformation, business alignment, IT strategy, topic modeling, LDA, CTM, BTM, HDP, STMen
