Graph Matching for Cultural Heritage

Graph Matching for Cultural Heritage

The Graph Matching tools are designed for performing pattern matching to find similar CH entities (e.g. artifacts, people, events) within CH RDF databases. These tools take as input SPARQL queries defining a subset of metadata to use (such as specifying that only the production method and material metadata should be considered) and output a similarity matrix giving pair-wise similarity between CH entities for this subset of metadata. The tools are accessed via command line and are thus designed for integration into a larger system.

The key USP of these tools is that they enable CH entity query and matching across all existing RDF metadata, NLP-generated annotations and shape/geometric annotations encoded as RDF. They thus perform the unique function of GRAVITATE in bringing together many search types into a single query. ITI has developed supporting scripts that import the similarity matrix and export RDF annotations for re-ingestion into a database. There is also a User Interface add-on to ResearchSpace which allows query by example based on data from a similarity matrix, creating a strong opportunity for exploitation through ResearchSpace.
