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

Data I/O

Accessing the Cloud

Shows how to access data from a cloud storage provider.

CSV Import

Shows how to import data from a CSV file using Rel.

CSV Export

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.

Modeling and Reasoning

The Lehigh University Benchmark

Demonstrates how to represent Web Ontology Language (OWL) constructs and write SPARQL/RDF queries in Rel.
