Event description

Andean textiles are products of one of the richest, oldest and continuous weaving traditions in the world. However, due to the erosion of local traditions, some of this knowledge is in danger of being lost and it is important to preserve the valuable cultural heritage connected to it. We modeled the knowledge of domain experts and represented information about the textile objects in the form of an OWL ontology. We also developed a suite of search facilities, making the digitized fabrics accessible to domain experts and researchers in the area. Among these techniques is a novel approach for measuring the similarity between weaving patterns that can provide similarity-based search functionality for textile archives. We represent textile structures using hypergraphs, extract feature sets from these graphs, and compare these sets with different similarity measures. We illustrate the effectiveness of this technique via an experimental evaluation.
