Why use Superlinked

Improve your vector search relevance by encoding your metadata together with your data into your vector embeddings.

What is Superlinked

Superlinked is a framework AND a self-hostable REST API server that helps you make better vectors, that sits between your data, vector database and backend services.

How does it work

Superlinked makes it easy to construct custom data & query embedding models from pre-trained encoders, see the feature and use-case notebooks below for examples.

Features

• Embed structured and unstructured data (Text | Number | Category | Time | Event)
• Combine encoders to build a custom model (notebook)
• Add a custom encoder (notebook)
• Update your vectors with behavioral events & relationships (notebook)
• Use query-time weights (notebook)
• Query with natural language (notebook)
• Filter your results (notebook)
• Export vectors for analysis (notebook)

You can check a full list of our features or head to our reference section for more information.

Use-cases

Dive deeper with our notebooks into how each use-case benefits from the Superlinked framework.

• RAG: HR Knowledgebase
• Semantic Search: Movies, Business News, Product Images & Descriptions
• Recommendation Systems: E-commerce

Example on combining Text with Numerical encoders to get correct results with LLMs.

Install the superlinked library

%pip install superlinked

Run the example:

First run will take slightly longer as it has to download the embedding model.

Run in production

Superlinked Server allows you to leverage the power of Superlinked in deployable projects. With a single script, you can deploy a Superlinked-powered app instance that creates REST endpoints and connects to external Vector Databases. This makes it an ideal solution for those seeking an easy-to-deploy environment for their Superlinked projects.

Reference

1. Describe your data using Python classes with the @schema decorator.
2. Describe your vector embeddings from building blocks with Spaces.
3. Combine your embeddings into a queryable Index.
4. Define your search with dynamic parameters and weights as a Query.
5. Load your data using a Source.
6. Define your transformations with a Parser (e.g.: from pd.DataFrame).
7. Run your configuration with an Executor.

Logging

Contextual information is automatically included in log messages, such as the process ID and package scope. Personally Identifiable Information (PII) is filtered out by default but can be exposed with the SUPERLINKED_EXPOSE_PII environment variable to true.
