Grammar development as an interactive process

A linguist such as yourself who is developing a grammar and a lexicon performs the following tasks, shown in the Figure (1).

1. defines a grammar and lexicon as a linguistic theory of a natural language,
2. formulates the grammar and lexicon as an operationalised theory in Prolog,
3. poses a query,
4. calls the Prolog interpreter,
5. checks the responses and
6. the error output,

and repeats these steps for as many cycles as necessary.
