Eckhard Bick - VISL

(5) Syntactic tree structures (VISL simplified notation)
For the sake of pedagogical continuity, and in order to facilitate integration of
internet tree-analyses into pre-existing grammar courses, corpora of text book
sentences can be tagged manually or semi-automatically according to the needs of
individual teachers or teaching institutions, creating “closed corpora” for easy (and
error-free) reference 238 . Likewise, individual notational tag filters can be crafted
“made to order”.
7.2.6. Student driven interactive analysis
In the interactive analysis mode, a full analysis is computed by the server, but the
Constraint Grammar tags remain concealed as hidden parameters in the html-forms
238 The “closed corpus” approach also allows integrating into the VISL system languages that have not yet Constraint
Grammar systems at their disposal for live analysis (Danish, French, Italian), or lack the necessary syntactic CG module
(German). The English VISL system is the one most closely integrated into an existing teaching program. Thus, the
English VISL group at OU, supervised by John Dienhart, has hand-tagged a text book corpus containing all exercises
from (Bache et. al., 1993), using the book’s tag sets for form and function, and a tree coding scheme compatible with
the existing tree-designing module of the Portuguese system.
