Long-Term News LLM RAG

Analyze long-term trends from weekly news publications.

Replicate

To replicate the environment and support Jupyter notebooks, follow these steps:

# Install pipenv
pip install pipenv

# Enter the virtual environment
pipenv shell

# Install ipykernel to support Jupyter notebooks
pipenv install ipykernel

# Also, install this to support Jupyter notebooks
pipenv install notebook jupyterlab 

To run a notebook:

pipenv shell
pipenv run jupyter notebook    

Scripts

The project includes several scripts for data extraction and processing:

1. RSS Feed Data Collection (scripts/01_get_rss_data.py)

  • Fetches initial RSS feed data
  • Stores raw feed data for further processing

2. Content Data Extraction (scripts/02_get_content_data_flattened.py)

  • Processes RSS feed entries using GPT-4-mini
  • Extracts two types of content:
    1. Individual News:
      • Start and end dates
      • Ticker symbol
      • News count
      • Growth percentage
      • News text
    2. Market News (1-day and 1-week summaries):
      • Model name
      • Time period
      • News count
      • Market summary text
  • Adds source link to each entry
  • Saves data in a flattened Parquet format

To run the content extraction:

python scripts/02_get_content_data_flattened.py

Search Functionality

The project implements text search capabilities using minsearch, allowing efficient search across all data fields:

Searchable Fields

  • type: News entry type (individual/market)
  • start_date & end_date: Time period of the news
  • ticker: Company/stock ticker symbols
  • count: Number of news items
  • growth: Growth percentage
  • text: Main news content
  • model: Model name for market summaries

Search Features

  • Full-text search across all fields
  • Field boosting (prioritizes matches in important fields):
    • text (3x boost)
    • type and ticker (2x boost)
    • growth and model (1.5x boost)
    • other fields (1x boost)
  • Link-based filtering for source tracking

Example usage in notebooks:

# Basic search
results = search_news("technology growth")

# Search with link filtering
results = search_news("market analysis", link="specific_url")

# Custom field boosting
custom_boost = {
    "ticker": 3,
    "text": 2,
    "type": 1
}
results = search_news("AAPL earnings", boost_dict=custom_boost)

Data

Input Data

RSS feed with news (mostly weekly, some weeks are missing)—around 46 weeks or 1 year of data:

Output Data

The processed data is saved in Parquet format with the following structure:

  1. Individual News Entries:
{
    "type": "individual",
    "start_date": "date",
    "end_date": "date",
    "ticker": "symbol",
    "count": number,
    "growth": percentage,
    "text": "news content",
    "link": "source_url"
}
  1. Market News Entries:
{
    "type": "market_[period]",  # period can be "1day" or "1week"
    "end_date": "date",
    "start_date": "date",
    "ticker": "multiple_tickers",
    "count": number,
    "model": "model_name",
    "text": "market summary",
    "link": "source_url"
}

The data is saved to data/news_feed_flattened.parquet using Brotli compression for efficient storage.
