SDM Lab 2 - Knowledge Graphs

This repository contains the solutions and resources developed for Lab Assignment 2. The lab focuses on hands-on work with knowledge graphs, involving RDF schema modeling, data transformation using RDFLib, and semantic querying using SPARQL in GraphDB.

---

🧠 Project Overview

The main objectives of this lab were:

• Design and implement an ontology (TBOX) for the research publication domain.
• Create an instance dataset (ABOX) using RDFLib based on structured data.
• Use reasoning and inference in GraphDB to enhance semantic querying.

⚙️ Setup Instructions

1. Install GraphDB
   Download and install GraphDB Free:
   👉 https://www.ontotext.com/products/graphdb/graphdb-free/

2. Start GraphDB
   Launch the application and access http://localhost:7200/

3. Create a Repository

   • Go to Setup > Repositories > Create new repository
   • Use ruleset: RDFS (Optimized)
   • Enable autocomplete in Setup > Autocomplete

4. Import RDF Data
   Load the TBOX and ABOX files into the GraphDB repository via the Import > RDF tab:

5. Run Queries
   Go to the SPARQL tab and run the provided queries in the assets/ directory.
