Topic Modeling Using Latent Dirichlet Allocation
Portland Community Church

Philip Robinson will be presenting research whilst at NASA on Topic Modeling.

Topic modeling is the task of taking a collection of objects and establishing a strategy for describing these objects by common categories found across the collection. This is usually an unsupervised activity applied to a document collection and doesn't require topics to be human interpret-able. My talk introduces Latent Dirichlet Allocation, as a topic modeling strategy for a collection of topics, and discusses an implemented prototype system I developed for NASA's Jet Propulsion Lab. For this project, I addressed the "Matchmaker's Problem" in the context of identifying the best employee to solve a mission-critical engineering anomaly in late-stage missions. The long-form presentation can be found here https://github.com/probinso/expert-modeling-system/blob/master/decks/itds/pres.pdf
