Example: What inferences do we have of the form:
We parse and label the premise:
In this expression, we see these polarities
So we have the following inferences
Every student carefully reads some big book
Therefore,…
((carefully reads) ↑ (some (big book) ↑ )) ↑ (every student ↓ )) ↑
+1 (carefully reads)
+1 (big book)
+1 (carefully reads some big book)
-1 student
(carefully reads some big book)(every student) (Greek∧student)≤student
(carefully reads some big book)(every (Greek∧student))
[mon]
(carefully reads some big book)(every student) (carefully reads)≤reads
(reads some big book)(every student)
[mon]
(carefully reads some big book)(every student) (big book)≤book
(carefully reads some book)(every student)
[mon]
Example: What inferences do we have of the form:
We parse and label the premise:
In this expression, we see
So we have the following inferences
No student reads every big book
Therefore,…
(reads ↑ (every (big book) ↓ )) ↓ (no student ↓ )) ↑
-1 (reads)
+1 (big book)
-1 (reads some big book)
-1 student
(reads every big book)(no student) (Greek∧student)≤student
(reads every big book)(no (Greek∧student))
[mon]
(reads every big book)(no student) (carefully reads)≤reads
(carefully reads every big book)(no student)
[mon]
(reads every big book)(no student) (big book)≤book
(reads every book)(no student)
[mon]
