In Towards a Paradigmatic Description of Context: Systems, Metafunctions,
and Semantics (2014), Hasan illustrates how a paradigmatic
description of context can be accomplished using a system network, i.e.
sys-net. Sys-nets, which have successfully been used to account for variant
possibilities, i.e. choices, specific to parameters in other strata, e.g semantics
and lexicogrammar, may also be applied to the stratum of context. As
Hasan points out, however, ‘The problem is to establish their calibration in
a way that the realized actuals agree with the experience of the community
whose language and culture are under description.’
