The system consists of online and offline components.
Online Components
System Architecture: Online components
| Component | Description | I/O | Status |
|---|---|---|---|
| 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. |
| Evidence Finder | Provides evidence for the input proposition using weaker methods. | Input: Proposition Output: Rules/Axioms that derive the proposition (in one-step) weighted according to the confidence provided by each method. |
Not implemented. Previous iteration had a Jena implementation that is scrapped. |
| MLN Instance Generator | Converts the evidence into MLN input format. | Input: Facts as RDF triples, and rules in N3 notation. | 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. |
Offline 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. |
