Vulcan/MeetingNotes/Aug23 2013
From Knowitall
Update
- Created a plan for a prototype system that will work on three example questions.
- Stephen helped design a representation for the rules. We will have human-authored rules that will be translated to Tuffy's MLN format.
- See documents on rule representation and transforming to MLN syntax for details.
- Weak evidence finder.
- Greg is getting started on weak evidence finder.
- Started a specs page for this component.
- Greg will flesh out the details.
- How to perform procedural escapes within Tuffy or other MLN systems?
- Tuffy doesn't support procedural escapes but we can make do with some hacks.
- Tuffy allows built-in postgres functions in inference rules.
- We can write our own postgres procedures (e.g., stemmer, head word extractor etc.) that can be used as a function in the inference rule.
- Tuffy developers think this should be doable easily.
- Get a knowledge spec:
- isa, partOf, etc.
- We have portions of the Aura KB available but they may not be very useful for the current task (grade-level science vs. college level bio).
- Stephen to take lead on definition extractor.
- Send Stephen literature and other material for definition processing.
- What are the research problems?
- Definitions extractor
- Reading rules from text.
- Abductive reasoning
- Procedural escapes for textual matching.
