How-To Guides

A set of how-to guides demonstrating how to use Rel to solve concrete problems.

How-To Guides are designed to guide you through the steps needed to take on specific tasks and problems. They are more advanced than Tutorials and assume some background knowledge of the Rel language and the RKGMS.

List of How-To Guides

I/O Tools

CSV Import

This guide shows how to import data from a CSV file using Rel.

CSV Export

This guide shows how to export data from a CSV file using Rel.

JSON Import and Export

This guide covers Rel's importing and exporting utilities for data in the JSON format.

Data Visualization

This How-To Guide demonstrates how to create graphical representations of data with Rel and Vega-Lite.

Data Modeling

OWL and Rel: Data Modeling

This guide demonstrates how we can represent Web Ontology Language (OWL) constructs and write SPARQL/RDF queries in Rel.

Machine Learning

Classification

As part of a larger series of Rel machine learning guides, this guide will focus on classification. Specifically, we will explore how to load a dataset, build a classification model, and perform predictions using that model.

Regression

As part of a larger series of Rel machine learning guides, this guide will focus on regression. Specifically, we will explore how to load a dataset, build regression models using glm and mlpack bindings, and perform predictions using these models.
