<p>noon - 1 pm</p>

<p>Large Language Models for Social Science at Scale</p>

<p>Ashrakat Elshehawy</p>

<p>The session will show how social scientists can use LLMs to extract structured information from messy, unstandardized textual data, such as media reports, websites, or administrative documents, at scale. We will cover practical prompt-engineering techniques. The session will walk through simple, adaptable code for classification and information extraction, and introduce basic verification strategies (performance metrics, human-in-the-loop checks, and consistency tests) to ensure reliability.</p>

<p>What You’ll Learn: Structural Topic Modeling in R</p>

<p>This session introduces how to uncover hidden themes in large text collections using Structural Topic Modeling (STM). Participants will learn to:</p>

<p>Prepare and clean text data for analysis.</p>

<p>Tokenize and filter words, removing stopwords and applying word stemming.</p>

<p>Use TF-IDF to identify meaningful words and visualize word frequency patterns.</p>

<p>Build and interpret an STM, discovering key topics and how they vary across groups (e.g., by gender).</p>

<p>Load and prepare labeled text data, cleaning and restructuring it for analysis.</p>

<p>Convert model predictions into binary classifications for comparison.</p>

<p>Join automated and manual classifications to assess accuracy.</p>

<p>Use confusion matrices to measure model performance across different topics.</p>

<p>Oct 10 2025 - Nikolay Marinov - Machine-Learning to Classify Images:</p>

<p>Beginner-friendly workshop introducing how machine learning can be used to analyze and classify images — from detecting faces and identifying objects to training simple models that distinguish between categories such as male and female politicians’ social media banner images. Using Google Colab and Python libraries like OpenCV, Hugging Face’s transformers, and PyTorch, participants learn the full workflow: setting up datasets, applying pre-trained models for visual recognition, labeling and training supervised models, and evaluating performance metrics like accuracy and F1 scores. We use the social media banner pictures of members of the European Parliament.</p>
