In o de o make clea wha is mean I will illus a e he espec i e le els one by one in he nex sec ions. 2.1. Domain modelling I a e minological da abase is mean o deal wi h knowledge and wi h i s managemen , hen i has o p o ide o a model ep esen ing he way how he ‘(sub-)wo ld’, he domain, is o ganised/s uc u ed. So, o in- s ance, in medicineone basic concep , iz. ha o disease(nosologyin igu e 1 below) s uc u es he whole ield. I is he cen al o ganising p inciple wi hin his ‘wo ld’. I one alks abou body-pa s he e, i is be- cause o he ac ha hey a e/can be a ec ed; i one alks abou o ganisms he same applies; he apeu ic p ocedu es only make sense when hey e- e o diseases and so a e symp oms ( indings), causes (e iology) e c. E e y hing in he medicinal wo ld is linked di ec ly o indi ec ly ( ia o he concep s) o he cen al concep disease.The amoun and g anula - i y o he in o ma ion gi en abou o he concep s is de ined by his di ec o indi ec ela ionship. Domain modelling, he e o e, is acondi iosine quanonwi hou which i is impossible o cons uc a e minological da- abase. In igu e 1 a simpli ied schema ic ep esen a ion is gi en o such domain modelling o medicine[ o mo e de ails see Ma in e.a. 1991]. As one can obse e, all main ca ego ies a e cen ipe ally ela ed o disease (nosology): ana omy (MEMF) and o ganisms by he ‘a ec ’ ela- ion, e iology by he ‘caused by’ ela ion, indings by he ‘symp oms’ ela- ion, he apeu ic p ocedu es by he ‘ ea ’ ela ion e c. Typically hen he medicinal domain is a domain which is well delinea ed and cen alised: a domain wi h one cen al/co e ca ego y o which all o he ca ego ies a e ela ed. I goes wi hou saying ha aking he same objec s and pu ing hem in o a di e en domain (‘d ugs’ in medicine e sus he same ca e- go y in pha macy)al e s he s uc u e o he ield and he amoun and cha ac e o he knowledge ha should be exp essed. Tha is, among o he s, one o he easons why domain modelling is c ucial when s a ing wi h he cons uc ion o a TD and dealing wi h knowledge ep esen a ion. Te minologija | 2010 | 17 2 3 Figu e 1: Example o a ‘delimi ed’ cen alised domain (medicine) No all domains show he same kind o s uc u e hough. So, o in- s ance, in igu e 2 an example is gi en o he domain o educa ional sys ems,which has an embedded o onion-like s uc u e.

Da a modelling unde da a modelling I he e unde s and he modelling o da a as in a da abase, implying • he de ini ion o he en i ies in he model and hei ela ionships (e.g. e ms, concep s, colloca ions and he ela ions/links ha exis be ween hem) and • he de ini ion o he da a ca ego ies o he di e en en i ies (bo h he a ibu es and he [domains o hei ] alues). Indeed, in a da a model one does no only ha e o make clea wha  one wan s o ep esen om a con en s poin -o - iew (see 2.1 abo e: he gene al amewo k o mac os uc u e o he wo ld/domain o be ep e- sen ed), bu also howone will do so: by means o which o mal objec s, en i ies and ela ions.

Figu e 4 can gi e an idea o wha is mean . As one will obse e, di e en g aphic i ms a e used o dis inguish be ween: • concep s (c), • e ms (T) and • colloca ions (cOLL).
