When dealing with verbs, MyTalk uses a call to the wordnet predicate fr(synset_id,f_num,w_num) in order to find the frames of the verb to check whether it’s bi-transitive (f_num of 14 would be a bi-transitive verb, for example).

Currenlty, MyTalk prints “too difficult” for almost any sentence, but the fr(synset_id,f_num,w_num) seems behave as if it is actually fr(synset_id,w_num,f_num) with the f_num and w_num reversed. For the verb “give”, the second argument is always 0 (default word number for a synset?), and the third argument has various frame numbers, including 14 for a bi-trasitive verb.

By changing MyTalk to swap the positions of w_num and f_num, then MyTalk understands basic sentences, such as “terry gave shrdlu” which would be “too difficult” for the current master version of MyTalk.

This can be solved by reversing the order of the arguments: fr(SysID, FR, W_Num) becomes fr(SysID, _, FR) and this allows the verb number of the group (now second argument) to be anything, including 0 (the verb number for the framing seems to be 0 in a lot of cases which seems to mean there is a default framing for the verb group).

Thanks to Prof. Todd Kelley from Algonquin College for this precious suggestion. I hope one day I'll have time to do these changes (contributions will be really welcome).
