Feedback and Inference (contd.) Method 3 : Analogies as Inference Rules It first generates a list of inference rules. For this programs first tries to find a cycle. Rules are automatically extracted using OMCS-1 database. More matches ⇒ better rules. If two links for rules are discovered program can infer third User enters : Bats like darkness If db has : You might find bats near cave interiors and the corresponding rule, then it will infer Cave interior is a darkness A K Nirala Lexical Knowledge Structures
More user inputs Clarification by suggesting common words as replacement. common words extracted as frequency from OMCS-1 corpus. Replacement using synonym dictionaries. Users are prompted for WSD. Automated methods suggest sense tags. User only need to provide one or two senses. Concepts are linked to topic. Linking maintained as topic vectors. Facilitates wide knowledge retrieval.
