PyTextRank logo

a popular Python implementation of multiple textgraph graph algorithms for phrase extraction, provided as a configurable spaCy pipeline component.

  • lightweight phrase extraction (unsupervised learning, CPU-based)
  • leverages available NER capabilities within a pipeline
  • uses: enhance indexing and document similarity; building knowledge graphs
kglab logo

a simple Python abstraction layer for Graph Data Science, integrating NetworkX, RAPIDS, RDFLib, Morph-KGC, pythonPSL, and more.

  • provides PyData-esque interfaces to other popular graph libraries
  • includes several Jupyter-based graph data science tutorials
  • uses: building knowledge graphs; integrating disjoint graph technologies
mkrefs logo

MkDocs plugin to generate semantic reference Markdown pages from a knowledge graph

  • biblio – semantic bibliography entries, generated from RDF
  • glossary – semantic glossary entries, generated from RDF
  • apidocs – semantic apidocs supporting the Diátaxis grammar for documentation, generated as RDF from Python modules
disparity_filter logo

implements a disparity filter in Python, based on NetworkX, to extract the multiscale backbone of a complex weighted network (Serrano, et al., 2009)

  • analogous to centrality calculated on the edges of a graph rather than its nodes; in other words, consider this as a "dual" problem of the typical graph analysis of social networks
  • uses: paring down automatically-generated graphs, such as those produced by NLP methods

recommended projects within our community:

Our focus is on Python open source libraries for: building knowledge graphs, natural language, dataset quality embeddings, graph representation learning, probabilistic data structures, leveraging motifs, hybrid reasoning systems, semantic inference, graph visualization, network analysis, following the general criteria:

  • based on reasonably current dependencies
  • uses a business-friendly license
  • installs correctly with pip or conda
  • provides example code which runs without exceptions
  • reproduces published results
  • affords data integration (not optimized for benchmark/paper)
  • called as a library, not requiring container/microservice orchestration nor CLI
  • supports concurrency and parallelization
  • maintained within the past six months
  • passes a reasonable level of security audit
