AAAI 2025 Student Abstract
In this student paper, we report on our project to enhance road safety in South Carolina (SC) by analyzing traffic data provided by the Department of Transportation and evaluating the impact of a school-level student driver education program called Alive@25. We improve the understanding of road safety using these traffic and training data to understand collision patterns and areas for improvement and assess training coverage gaps. Our approach combines geospatial analysis, economic impact assessment, temporal trend analysis, and interactive visualizations while leveraging AI techniques to clean and analyze extensive datasets. Key findings revealed higher collision rates in urban counties and rising collision rates in mostly rural areas, where Alive@25 participation is declining. These insights led to recommendations for improving road infrastructure and expanding safety training programs. This research demonstrates the potential of AI-driven insights to inform timely, cost-effective interventions and promote multi-stakeholder engagement in addressing public safety challenges while teaching students data science and AI skills and civic engagement.
Revisiting LLMs in Planning from Literature Review: a Semi-Automated Analysis Approach and Evolving Categories Representing Shifting Perspectives
Tracking the rapidly evolving literature at the intersection of large language models (LLMs) and planning has become increasingly complex due to significant growth in research output and shifting thematic focuses. Building on the survey by Pallagani et al.(2024), which organized 126 papers collected till November 2023 into eight categories, we present a platform that automates the extraction, categorization, and trend analysis of new papers. Our analysis reports on category drift, identifying evolving perspectives on the use of LLMs for planning. Our analysis reveals a decline in the percentage of papers for six categories, an increase in two, and the emergence of two new categories. Specifically, we contribute by (1) developing an automated system for categorizing new papers into existing or emergent categories,(2) reporting on category shifts with the addition of 47 new papers till September 2024, and (3) introducing a platform for continuous extraction, categorization, and trend tracking in LLM and planning research. This platform also features a leaderboard to encourage innovations in automated paper categorization.

Ontologies are known for their ability to organize rich metadata, support the identification of novel insights via semantic queries, and promote reuse. In this paper, we consider the problem of automated planning, where the objective is to find a sequence of actions that will move an agent from an initial state of the world to a desired goal state. We hypothesize that given a large number of available planners and diverse planning domains, they carry essential information that can be leveraged to improve many ontology applications. We use open data on planning domains and planners to construct the most comprehensive planning ontology to date, based on supported competency questions, and demonstrate its applications in two practical use cases - planner selection and plan explanation. We have also made the ontology and associated resources available to the AI and data communities to promote further research.
On the Books in South Carolina: Mining for Jim Crow Laws

On the Books in South Carolina: Mining for Jim Crow Laws is a collections-as-data and machine learning project by the University of South Carolina Libraries (USC), sub awarded by the University of North Carolina at Chapel Hill (UNC), and made possible by The Andrew W. Mellon Foundation, for the period of May 2022-December 2024. Following UNC’s steps from their first year of the grant, the USC project created a text corpus of South Carolina state legislature acts passed in the period from Reconstruction through the Civil Rights Movement (1868-1968). The USC team then utilized machine learning techniques to create a model classifying the laws as either Jim Crow or not.
