FrameScope

FrameScope is a reproducible research pipeline for analyzing how people describe AI in real-world text.

The project collects Reddit data, normalizes and stores it, labels it with LLMs, and then produces weekly, monthly, yearly, and volume-shift summaries. It also includes an Arctic Shift client package, arcshiftwrap, for direct data collection from the Arctic Shift API.

Overview

FrameScope is designed to answer a practical question: how well do different models capture the language people actually use to talk about AI?

The repository combines:

• Reddit ingestion through Arctic Shift
• Cleaning and sentence-level preprocessing
• LLM-based metaphor and stance labeling
• Weekly, monthly, yearly, and shift summaries
• Benchmarking of GPT and local models against human annotations

Installation

Install the client package from PyPI:

pip install arcshiftwrap

Example usage:

from arcshiftwrap import ArcticShiftClient

client = ArcticShiftClient()
posts = client.search_posts(
    subreddit="MachineLearning",
    after="2024-01-01",
)

To work with the full repository locally:

git clone https://github.com/sagnik-chakravarty/FrameScope.git
cd FrameScope
python3 -m venv .venv
source .venv/bin/activate
python -m pip install --upgrade pip
pip install -r requirements.txt
pip install -e .

Benchmark Results

The LLM comparison notebook evaluates models on 4,147 labeled examples and reports classification performance using accuracy, macro F1, weighted F1, macro precision, macro recall, and Cohen's kappa.

Overall performance

Model	Accuracy	Macro F1	Weighted F1	Notes
gpt-4o-mini	0.7485	0.6717	0.7582	Best overall Macro F1 in the benchmark
gpt-4.1-mini	0.7311	0.6410	0.7381	Strong low-cost GPT option
gpt-4.1-nano	0.7335	0.6397	0.7401	Very competitive for its cost
llama3.1:8b	0.7333	0.6412	0.7362	Best local model by Macro F1
llama3.2	0.6639	0.5948	0.6753	Fastest local model in the latency benchmark

Key takeaways

• gpt-4o-mini is the strongest model overall on raw classification quality.
• gpt-4.1-nano and gpt-4.1-mini are the best GPT options when cost matters.
• llama3.1:8b is the strongest local model on this benchmark.
• llama3.2 is the most operationally efficient local option, with the lowest measured latency in the latency-cost comparison.

Latency and cost

The latency-cost comparison shows the practical trade-off between API-based and local models.

• gpt-4.1-nano recorded the lowest GPT cost in the comparison at about $0.1307 total.
• gpt-4o-mini delivered the best overall quality/cost balance among GPT models.
• llama3.2 had the lowest local average latency at about 0.47s per item.

Human baseline comparison

The older prompt benchmark in gpt41_old_prompt_overall_results.csv shows the value of the updated prompt and pipeline:

• gpt-4.1_old_prompt macro F1: 0.3148
• Updated benchmark models now reach roughly 0.59 to 0.67 macro F1 depending on the model

Pipeline

The weekly pipeline is orchestrated by Scripts/13_run_weekly_pipeline.py and runs the processing stages in order.

Step	Script	Purpose
00	Scripts/00_backfill_reddit.py	Backfill Reddit data from Arctic Shift into the raw store
01	Scripts/01_fetch_reddit.py	Fetch new Reddit data for the current run
02	Scripts/02_clean_store.py	Clean and normalize raw records into the processed layer
03	Scripts/03_sentence_preprocess.py	Split text into sentence-level records and prepare downstream inputs
04	Scripts/04_update_database.py	Load cleaned and processed data into the SQLite database
05	Scripts/05_label_llm.py	Apply LLM labels such as metaphor and stance
06	Scripts/06_weekly_aggregate.py	Build weekly aggregate summaries and example selections
07	Scripts/07_weekly_llm_summary.py	Generate weekly LLM summaries
08	Scripts/08_monthly_llm_summary.py	Generate monthly LLM summaries from weekly outputs
09	Scripts/09_yearly_llm_summary.py	Generate yearly LLM summaries from monthly outputs
10	Scripts/10_volume_shift_summary.py	Summarize month-over-month or year-over-year volume shifts
11	Scripts/11_archive_and_prune.py	Archive old data and prune working storage
12	Scripts/12_upload_aggregate_to_neon.py	Upload aggregate tables to Neon
13	Scripts/13_run_weekly_pipeline.py	Run the full pipeline end-to-end

Run the full weekly pipeline with:

python3 Scripts/13_run_weekly_pipeline.py

Useful options:

python3 Scripts/13_run_weekly_pipeline.py --skip-archive
python3 Scripts/13_run_weekly_pipeline.py --archive-dry-run
python3 Scripts/13_run_weekly_pipeline.py --skip-neon-upload

Directory Structure

Path	Purpose
arcshiftwrap/	Installable Arctic Shift client package
Scripts/	End-to-end pipeline stages and maintenance jobs
Notebooks/	Benchmarking, analysis, and debugging notebooks
Docs/	Project documentation and API notes
LLM results/	Shareable benchmark inputs, outputs, evaluation CSVs, and GPT batch artifacts
plots/	Generated charts and benchmark figures
Prompts/	Prompt templates and label schema files
Setup/	Environment bootstrap scripts and model installers

Generated data, database files, and other run artifacts are intentionally omitted from this overview because they are created locally and excluded from version control. The top-level LLM results/ directory is kept in version control so benchmark inputs and outputs remain easy to access.

Setup

1. Prepare Ollama models

This helper script installs Ollama if needed, starts the service when possible, and downloads any missing local models:

python Setup/download_ollama_models.py

2. Verify Ollama is running

curl http://localhost:11434/api/tags

If Ollama is working, you should see a JSON response.

3. Notes

• If you see connection refused, start Ollama with ollama serve.
• The downloader skips models that are already installed.
• Large local models such as llama3.1:70b may require significant RAM and disk space.
