Developed "TopicVisExplorer", a web-based tool that allows refinement and comparison of topic models with a novel topic similarity metric and refinement operations. A large user study was conducted to validate its usefulness. Supervisors: Dr. Evangelos Milios , Dr. Fernando Paulovich.
Developed a novel methodology for cross-language comparison of social media text to understand information privacy perspectives across different speakers. Analyzed unstructured textual social media data and published two conference papers on international computer science conferences. Supervisors: Supervisors: Dr. Cecilia Aragon (UW) , Dr. Claudia López (UTFSM).

Proposing a general-purpose visual commonsense generation model, VisualCOMET+, for the creation of structured commonsense triplets that can be used for downstream tasks. Also showing the success of the model in generating coherent and diverse topics for multimodal topic modeling.
Incorporating commonsense knowledge into CTM was explored using COMET and ConceptNet NumberBatch embeddings. Clustering was also investigated as an alternative to LDA-inspired techniques, with a discussion of the trade-off between the two and motivation to incorporate corpus-level semantic relationships into neural topic models.
A new topic modeling algorithm that incorporates commonsense knowledge to identify coherent topics in multimodal data is proposed. The algorithm was trained and evaluated on a dataset of 100K Antisemitic/Islamophobic posts from 4chan, demonstrating that injecting commonsense knowledge can improve the quality of topics generated by the algorithm.
Introducing an extended version of MultiModalTopicExplorer, a topic modeling visualization tool that allows users to identify and explore topics that align with their preferences and understanding of the domain. Results from a user study demonstrate improved task success rates and reduced physical and mental demands when using the user-adaptive version of the tool.
MultiModalTopicExplorer is an interactive visualization tool for topic modeling that addresses the limitations of current visualizations by allowing users to perform a qualitative analysis of results and displaying relevant images for each topic. A user study showed positive results in terms of task success.
