How To Install swish on Ubuntu 18.04
Introduction
In this tutorial we learn how to install swish on Ubuntu 18.04.
What is swish
swish is:
Swish is a framework for performing deductions in RDF data using a variety of techniques. Swish is conceived as a toolkit for experimenting with RDF inference, and for implementing stand-alone RDF file processors (usable in similar style to CWM, but with a view to being extensible in declarative style through added Haskell function and data value declarations). It explores Haskell as “a scripting language for the Semantic Web”.
Swish is a work-in-progress, and currently incorporates:
- Turtle, Notation3 and NTriples input and output. The N3 support is incomplete (no handling of @forAll).
- RDF graph isomorphism testing and merging.
- Display of differences between RDF graphs.
- Inference operations in forward chaining, backward chaining and proof-checking modes.
- Simple Horn-style rule implementations, extendable through variable binding modifiers and filters.
- Class restriction rule implementation, primarily for datatype inferences.
- RDF formal semantics entailment rule implementation.
- Complete, ready-to-run, command-line and script-driven programs.
This package contains the swish tool.
