So if it chooses the adverb interpretation of "significantly", it's then looking to start a new PHRASE with a space, which your rules don't allow for. The fix is to put SPACE at the end of your EFF rule. Some of your other rules (e.g., DDIPK) have similar issues. Your grammar is highly ambiguous. You can see all the possible parses with the command: => (insta/parses parsePK "Exposure to oral didanosine is increased significantly when coadministered with tenofovir disoproxil fumarate.") but that's a lot of possibilities to comb through. => (count (insta/parses parsePK "Exposure to oral didanosine is increased significantly when coadministered with tenofovir disoproxil fumarate.")) 228 That's in large part because each possible special word can be interepreted both as its special meaning and just simply as an ordinary word. Also there are multiple valid places to end a phrase and begin a new one. To help troubleshoot this particular problem, I used: (clojure.pprint/pprint (distinct (map second (insta/parses parsePK "Exposure to oral didanosine is increased significantly when coadministered with tenofovir disoproxil fumarate.")))) Since you were mainly concerned with what ended up in the first phrase, this was an easy way to look specifically at that behavior. Instaparse allows you to have ambiguity and to prioritize certain interpretations with the ordered choice operator, but there might be a more elegant way to express the grammar. There may be some people on the instaparse group who would find it a fun exercise to figure out how to make your grammar more elegant. If you continue to have issues, perhaps you could post some example sentences and how you'd like them to be parsed, and see if anyone wants to help out. Also, if the whitespace continues to be a complicating factor, try out the auto-whitespace feature I mentioned in my last message. -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
