Preface
!
The! IWOOD! 2014*! workshop! was! the! second! workshop! on! definitions! in! ontologies! in! as!
many! years.! The! first! workshop! (DO! 2013)! was! held! last! year! in! Montreal! in! conjunction!
with! ICBO! 2013.! The! focus! of! this! second! workshop! was! on! definition! practices! in! either!
human!or!machineSassisted!ontology!development.
!
Explicit! definitions! of! terms! in! ontologies! serve! a! number! of! purposes.! Logical! definitions!
allow! reasoners! to! create! inferred! hierarchies,! lessening! the! burden! of! asserting! and!
checking! the! validity! of! subsumptions.! Natural! language! definitions! help! to! ameliorate! the!
pervasive! problem! of! low! interSannotator! agreement.! In! specialized! domains,! experts! will!
know! their! own! field! well,! but! may! only! have! limited! knowledge! of! adjacent! disciplines.!
Good! definitions! make! it! possible! for! nonSexperts! to! understand! unfamiliar! terms! and!
thereby!make!it!possible!for!more!confident!reuse!of!terms!by!external!ontologies,!which!in!
turn!facilitates!data!integration.!
!
The! goal! of! this! workshop! was! to! bring! together! researchers! and! developers! in! the!
biomedical!domain!to!discuss!difficulties!that!arise!in!definition!construction!with!a!view!to!
sharing! strategies.! Even! within! the! narrow! domain! of! definition! construction,! crossS
fertilization! of! ideas! from! related! disciplines! should! yield! benefits! in! quality! and! help!
reinforce!common!approaches!and!identify!novel!ones.
!
The! communications! published! in! these! proceedings! address! the! theoretical,!
methodological,!and!pragmatic!criteria!one!should!consider!before!engaging!in!the!activity!
of! defining! terms! in! ontologies.! The! main! goals! of! the! first! article! are! to! shed! light! on! the!
nature! of! logical! and! textual! definitions,! to! explore! the! relationship! that! exists! between!
them,! and! to! make! recommendations! for! an! improvement! between! the! two.! The! second!
paper!addresses!issues!related!to!the!general!activity!of!defining!terms!as!illustrated!by!the!
definition!of!'sign'!and!'symptom':!asking!preliminary!questions;!looking!up!and!comparing!
existing! definitions;! considering! one’s! ontological! framework! (BFO,! other…);! taking! or! not!
into!account!actual!usages!of!the!terms;!discussing!the!relevance!of!alternative!definitions;!
etc.!The!last!communication!describes!how!definitions!can!be!used!to!assess!the!coherence!
and! overall! quality! of! an! ontology! according! to! some! prerequisites,! and! proposes! a!
systematic!methodology!for!revising!and!updating!existing!definitions!to!conform!to!the!set!
quality!criteria.
