SIFT: An Algorithm for Extracting Structural Information From Taxonomies [article]

Jorge Martinez-Gil
2016 arXiv   pre-print
In this work we present SIFT, a 3-step algorithm for the analysis of the structural information represented by means of a taxonomy.  ...  This method is particular relevant in scenarios where taxonomy alignment techniques exploiting textual information from taxonomy nodes cannot operate successfully.  ...  Comparing structural similarities It is possible to use our algorithm for extracting structural indexes of taxonomies in order to compare its structural similarity.  ...
