Semantra is a powerful tool designed for semantically searching documents, allowing users to query by meaning instead of merely matching text. Whether you’re a journalist, researcher, student, or historian, Semantra’s intelligent features help you sift through large volumes of data, making it easier to find the information you need.

Installation Guide

To get started with Semantra, you will first need to ensure that you have Python version 3.9 installed on your computer. Here’s how you can set it up:

• If you don’t have pipx installed, you can install it using the following command:

python3 -m pip install --user pipx

• If you have Homebrew installed, you may run:

brew install pipx

• After installing pipx, ensure the path settings are updated by executing:

python3 -m pipx ensurepath

• Open a new terminal window and install Semantra:

python3 -m pipx install semantra

You’re now ready to start using Semantra! If you encounter issues during installation or prefer a different setup, you can install it within a virtual environment. Here’s how:

python3 -m venv venv
source venv/bin/activate
pip install semantra

Using Semantra

Once Semantra is installed, it’s time to make it work for you. Semantra operates on collections of documents stored locally. To search through a single file, use the command:

semantra doc.pdf

For multiple documents, you can run:

semantra report.pdf book.txt

Semantra will first process the documents which may take some time. After processing, it will launch a local web server at localhost:8080, allowing you to interactively query the documents semantically through an easy-to-use web interface.

Understanding Your Search Results

When you enter a query, Semantra will display results sorted by relevance on the left side of the interface. The scores indicate how closely the results match your query, ranging from 0 to 1. A score of 0.5 or higher denotes a strong match. Highlighting important sections of text also helps you pinpoint the most relevant information.

Think of Semantra as a librarian who doesn’t just point you to books but highlights the most pertinent chapters based on your questions. Just as a librarian has a vast understanding of context, Semantra uses advanced algorithms to interpret the meaning behind your queries.

Troubleshooting Common Issues

If you encounter difficulties while setting up or using Semantra, here are some troubleshooting ideas:

• Ensure that your Python version meets the required specification (3.9).
• If Semantra is not launching correctly, confirm that pipx is correctly installed and that your path settings have been updated properly.
• If search results are not appearing or are irrelevant, double-check your query for specific keywords or try rephrasing it for better context.
• If you are looking to customize the machine learning model used, refer to the models guide for more details.
