Update
- Focusing on system development.
- 1. Online components implemented. See System development status for details.
- Proposition generator
- Evidence finder -- Tuple matching over Open IE Clueweb data.
- 2. Components tested using ...
- 3. Evaluation...
- Vulcan has a good evaluation interface setup. We will use this for starters.
- Design questions.
- 1. Why not use MLN directly? Why use a backward chained inferencer (such as Jena) as an intermediate step?
- Looks like a separte backward-chained inferencer won't be necessary.
- Tuffy, an MLN implementation, does KBMC to scale MLN inference. Details [1]
- Analysis
- 1. Selected 10 propositions that are single Open IE tuples as starting targets.
- 2. Wrote down steps involved in verifying these propositions.
Agenda
To Do (Copied over from previous week)
- System building
- 1. Implement "template matching" using the ClueWeb corpus.Pending
- URL for Open IE backend is available.
- For an assertion A, find sentences that have high overlap. Generate regex patterns for the proposition. Score sentences by how well they match the regex patterns.
- 2. Continue system building.
- Create a derivation scorer stub. This will be replaced with a MLN or a BLP scorer. Done.
- Test with iron nail example.
- 3. Jena API doesn't readily support multiple derivations.
- Ask Jena community to find out if this is possible. Done. Not possible.
- OWLIM as replacement. Done. Doesn't look promising. No response from community.
- 4. Try out Tuffy MLN implemenatation. Done.
- Use output of iron nail example
- If easy to use write wrappers around Tuffy to hook into our system.
- 5 Write evaluation code. Vulcan has a good interface set up.
- Check with Peter.
- 6. Create a system architecture page with a figure and overview of the main components.
Created a System status page instead.
- Created a figure. Added it to system design document.
- Need to create a wiki page for system architecture and overview.
- Experiments Pending
- 1. Run template matching approach as a baseline.
- 2. Run inference system as a baseline.
