摘要：The international break-through of the ENGCG Parser, or the Constraint
Grammar Parser of English (Karlsson et al. 1995), as a system suitable
for analysing Present-day English, opened the field for applications
capable of dealing with regional, diachronic and other varieties of
English. Using the parser on historical data is an obvious extension. To
what extent should one "teach" the parser to cope with language from
earlier periods? To what extent does Present-day English differ from
early English and to what extent is it possible to formalize this difference
for the parser?
