Abstract:The purpose of this thesis was testing and evaluating the performance of different topic models at modeling prominent and returning topics in autobiographical memories of older adults. The models where evaluated on their topic coherence and topic variety. The best performing models in terms of coherence were the ones using noun phrases and words of high and low valence as input. The model with the greatest difference between the topics was an N-Gram topic model. The most common topics found were related to subjects like life and family.
