The system consists of Inference (online) and Axiom and Rule generation (offline) components.
Inference Components
System Architecture: Online components
| Component | Description | I/O | Status | To Do |
|---|---|---|---|---|
| Proposition Extractor | Extracts propositions to be verified by the system | Input: Sentence asserting the answer choice. Output: A proposition represented as a open IE tuple. |
Stub implemented: Sentence piped into Open IE 4.0. Output tuples that fit a specified pattern are converted into a proposition. | * Select the best tuple. |
| Evidence Finder | Provides evidence for the input proposition using weaker methods. Note: Not using Jena as a evidence finder anymore. Tuffy is optimized for efficient inference. |
Input: Proposition Output: Rules/Axioms that derive the proposition (in one-step) weighted according to the confidence provided by each method. |
Jena evidence finder partly implemented. Produces a single derivation, which needs to be converted to axioms and rules. Tuple matcher not implemented. Pattern matcher implementation underway. Uses Open IE solr instance to find matching sentences. | |
| MLN Instance Generator | Converts the evidence into MLN input format. | Input:Axioms/Rules from weaker methods. Output:Translated into Tuffy's input format. |
Stub implemented: Does a faithful translation from RDF to MLN format. | |
| End-to-End Driver | Command line application. | Input: Sentence asserting an answer choice. Output:Score |
Stub implemented. |
Axiom and Rule Generation Components
System Architecture: Offline components
| Component | Description | I/O | Status |
|---|---|---|---|
| Axioms Extractor | Generates axioms from multiple knowledge sources. | Input: Output: |
None. |
| Rules Generator | Uses second order rule templates to generate first-order inference rules. | Input: Output: |
None. |
