### Applications

While summarization is the focus of this tutorial, the same principles can be applied to any task involving text generation. The goal is to evaluate the consistency of the generated text with the input text. Other tasks involving text generation are entity recognition, question answering, and machine translation.

### Prerequisites

This tutorial assumes that you have already the following tutorials: [Quickstart](/v0.23.x/quickstart.md) and ideally [Trading Strategy](/v0.23.x/tutorials/trading-strategy.md).

### Organization

This tutorial requires a good deal of preparation, so it has been divided into the following four sections:

* Defining the text summarization problem of interest, including the data source and the metrics,
* Creating a constrained optimization problem to govern the development of a text summarization app in dbnl,
* Managing the integration testing process for consistent testing after such an app has been created,
* Practical considerations which would arise when actually building an LLM summarization tool.
