 LOTUS (**L**LMs **O**ver **T**ables of **U**nstructured and **S**tructured Data) provides a declarative programming model and an optimized query engine for serving powerful reasoning-based query pipelines over structured and unstructured data! We provide a simple and intuitive Pandas-like API, that implements **semantic operators**. 
 
-## Key Concept: Semantic Operators
-LOTUS' programming model is powered by semantic operators. We define semantic operators as declarative transformations on one or more datasets, parameterized by a natural language expression, that can be implemented by a variety of AI-based algorithms. Semantic operators seamlessly extend the relational model, operating over tables that may contain traditional structured data as well as unstructured fields, such as free-form text. These composable, modular language- based operators allow you to write AI-based pipelines with high-level logic, leaving the rest of the work to the query engine! Each operator can be implemented and optimized in multiple ways, opening a rich space for execution plans, similar to relational operators. To learn more about semantic operators, read the full [research paper](https://arxiv.org/abs/2407.11418).

 LOTUS offers a number of semantic operators in a Pandas-like API, some of which are described below.
