Representation and Reconstruction of a Representee with respect to a Base:

Representation: [ \, p_{resentant} \, ]_{P_{aradigm}} \, = \, \left< \, r_{epresentant} \, \right>_{P_{aradigm}} \, = \, \left< \, m_{odel} \, \right>_{P_{aradigm}}

A total representation enables a

Total Reconstruction: \left( \, \left< \, r_{epresentant} \, \right>_{P_{aradigm}} \, \right)_{P_{aradigm}} \, = \, p_{resentant}

Non-total representations are called partial, because they allow partial reconstruction of the presentant (see below).

///////

P_{aradigm} = B_{ackground} = B_{ase} = B_{asis} = ...

Representation: [ \, p_{resentant} \, ]_{B_{ackground}} \, = \, \left< \, f_{oreground} \, \right>_{B_{ackground}} \, = \, \left< \, i_{mage} \, \right>_{B_{ackground}}

Representation: [ \, G_{round} \, ]_{B_{ack}G_{round}} \, = \, \left< \, G_{round}R_{epresentation} \, \right>_{B_{ack}G_{round}}

Representation: [ \, B_{ackground} \, ]_{C_{onzilla}} \, = \, \left< \, C_{ontext}, P_{urpose}, T_{argetgroup} \, \right>_{C_{onzilla}}

///////

Representation:

[ \, B_{ack}G_{round} \, ]_{B_{ack}(B_{ack}G_{round})} \, = \, \left< \, (B_{ack}G_{round})R_{epresentation} \, \right>_{B_{ack}(B_{ack}G_{round})}

///////

PARTIAL REPRESENTATIONS

An example from the labour market:

Representation: [ \, e_{mployee} \,]_{L_{abourLaw}} = \left< \, e_{mployeeConcept} \, \right>_{L_{abourLaw}}

Partial Reconstruction: \left( \, \left< \, e_{mployeeConcept} \, \right>_{L_{abourLaw}} \, \right)_{L_{abourLaw}} = e_{{mployee}_{LL}}

///////

Representation: [ \, e_{mployee} \,]_{T_{axLaw}} = \left< \, e_{mployeeConcept} \, \right>_{T_{axLaw}}

Partial Reconstruction: \left( \, \left< \, e_{mployeeConcept} \, \right>_{T_{axLaw}} \, \right)_{T_{axLaw}} = e_{{mployee}_{TL}}

///////

IMPORTANT: Both of these representations are partial, which means that an employee cannot be uniquely reconstructed from neither its WorkLaw nor its TaxLaw representation. In general we have \, e_{{mployee}_{LL}} \not = e_{{mployee}_{TL}} \not = e_{mployee} .

RESPONSE: These representations have different contexts, purposes, and target groups. The modeling process should therefore focus on behaviour (that is described by VERBS) and not on properties (that are described by NOUNS and ADJECTIVES).

/////// In Swedish:

Ett Exempel Från Arbetsmarknaden:

Representation: [ \, a_{rbetstagare} \,]_{A_{rbetsRätt}} = \left< \, a_{rbetstagarBegrepp} \, \right>_{A_{rbetsRätt}}

Partiell Rekonstruktion: \left( \, \left< \, a_{rbetstagarBegrepp} \, \right>_{A_{rbetsRätt}} \, \right)_{A_{rbetsRätt}} = a_{{rbetstagare}_{AR}}

///////

Representation: [ \, a_{rbetstagare} \, ]_{S_{katteRätt}} = \left< \, a_{rbetstagarBegrepp} \, \right>_{S_{katteRätt}} \,

Partiell Rekonstruktion: \left( \, \left< \, a_{rbetstagarBegrepp} \, \right>_{S_{katteRätt}} \, \right)_{S_{katteRätt}} = a_{{rbetstagare}_{SR}} \,

///////

VIKTIGT: Båda dessa representationer är partiella, vilket betyder att arbetstagaren inte kan unikt rekonstrueras från vare sig sin arbetsrättsliga eller sin skatterättsliga representation.
I allmänhet gäller \, a_{{rbetstagare}_{AR}} \not = a_{{rbetstagare}_{SR}} \not = a_{rbetstagare} .

RESPONS: Dessa representationer har olika sammanhang, syfte(n), och målgrupp(er). Modelleringsfokus bör därför ligga på beteenden (som beskrivs med VERB) och inte på egenskaper (som beskrivs med SUBSTANTIV och ADJEKTIV).

///////

Representation: [ \, A_{rbetsRätt} \, ]_{C_{onzilla}} = \left< \, S_{{ammanhang}_{AR}}, S_{{yfte}_{AR}}, M_{{ålgrupp}_{AR}} \, \right>_{C_{onzilla}}

Representation: [ \, S_{katteRätt} \, ]_{C_{onzilla}} = \left< \, S_{{ammanhang}_{SR}}, S_{{yfte}_{SR}}, M_{{ålgrupp}_{SR}} \, \right>_{C_{onzilla}}

/////// Back to English:

Representation: [ \, L_{abourLaw} \, ]_{C_{onzilla}} = \left< \, C_{{ontext}_{LL}}, P_{{urpose}_{LL}}, T_{{argetgroup}_{LL}} \, \right>_{C_{onzilla}}

Representation: [ \, T_{axLaw} \, ]_{C_{onzilla}} = \left< \, C_{{ontext}_{TL}}, P_{{urpose}_{TL}}, T_{{argetgroup}_{TL}} \, \right>_{C_{onzilla}}
