A network-based analysis of disease modules from a taxonomic perspective

no code implementations1 Apr 2021 Giorgio Grani, Lorenzo Madeddu, Paola Velardi

Proximity relationships of disease modules (hereafter DMs) in the human interactome network are now increasingly used in diagnostics, to identify pathobiologically similar diseases and to support drug repurposing and discovery.

Multiple Knowledge GraphDB (MKGDB)

no code implementations LREC 2020 Stefano Faralli, Paola Velardi, Farid Yusifli

MKGDB, thanks the versatility of the Neo4j graph database manager technology, is intended to favour and help the development of open-domain natural language processing applications relying on knowledge bases, such as information extraction, hypernymy discovery, topic clustering, and others.

A New Method for Evaluating Automatically Learned Terminological Taxonomies

no code implementations LREC 2012 Paola Velardi, Roberto Navigli, Stefano Faralli, Juana Maria Ruiz Martinez

Our method assigns a similarity value B{\textasciicircum}i{\_}(l, r) to the learned (l) and reference (r) taxonomy for each cut i of the corresponding anonymised hierarchies, starting from the topmost nodes down to the leaf concepts.
