Earley recognizer to Earley parser

I managed to create Earley recognizer, everything works fine. I have all proper sets of situation. But I only can use it to decide if word is accepted by grammar. How to make it to parse? I need some article or explanation, it seems that I need to create associations to situations that made new situations. Any help would be appreciated.

My implementation it's based exactly on: http://www.cs.uvic.ca/~nigelh/Publications/PracticalEarleyParsing.pdf
