toposkg 0.2.8

A Python interface to the ToposKG knowledge graph generation pipeline.

toposkg-lib

A Python library for Knowledge Graph customization and expansion.

Overview

toposkg-lib is a Python library developed as part of the Topos framework. It provides easy access to powerful functionality for customizing and extending ToposKG but is also compatible with arbitrary source files.

Highlights

• Powerful features. Customize and expand ToposKG using powerful tools for geospatial interlinking, toponym translation and entity linking.
• Ease of use. toposkg-lib is designed around a simple builder pattern, simplifying the process of generating your Knowledge Graph.
• Natural Language Interface. toposkg-lib can be used with a textual interface, powered by LLM function calling.
• Active development. toposkg-lib will keep getting updates as we work on our projects.

Repository contents

• examples/: Additional data, used in examples.
• notebooks/: Jupyter Notebooks that showcase the functionality of the library.
• toposkg/: The source code. Some files contain main functions that also include examples of use.

Getting Started

pip

We recommend using toposkg-lib through pip.

pip install toposkg

If you want to include the translation functionality.

pip install toposkg[tl]

If you want to include the function calling functionality.

pip install toposkg[fc]

We recommend that you install this custom version of RDF-lib before using toposkg-lib.

pip install git+https://github.com/SKefalidis/rdflib-speed@main

Otherwise you can use the original rdflib.

Simple example

from toposkg.toposkg_lib_core import KnowledgeGraphBlueprintBuilder, KnowledgeGraphSourcesManager

# Create a KnowledgeGraphSourcesManager object to load the available data sources and their metadata
sources_manager = KnowledgeGraphSourcesManager(['PATH_TO_YOUR_SOURCES'])

# See the available data sources
sources_manager.print_available_data_sources()

# Create a KnowledgeGraphBlueprintBuilder object to build the knowledge graph blueprint
builder = KnowledgeGraphBlueprintBuilder()

builder.set_name("ToposKG.nt")
builder.set_output_dir("/home/example/")

builder.add_source_path("PATH_TO_KG_SOURCE_1") # relative or absolute path
builder.add_source_path("PATH_TO_KG_SOURCE_2")

# Use the blueprint to construct the knowledge graph
blueprint = builder.build()
blueprint.construct()
