-  Pairs of training tuples are taken to produce a system that maps new questions to their logical forms.
-  A common baseline algorithm is a simple sequence-to-sequence model,

Ending results of Sematic Parsing QA

- A semantic parser is used to map the question to a structured program to produce an answer. These logical forms can take the form of some version of predicate calculus, a query language like SQL or SPARQL.
-  Semantic parsing algorithms can be supervised fully with questions paired with a hand-built logical form or can be weakly supervised by questions paired with an answer.

The system builds a semantic representation of the query and then use it to query databases of facts

Knowledge-based Question Answering (QA)

+ An RDF triple is a 3-tuple, a predicate with two arguments, expressing
some simple relation or proposition.
+ Can be used to answer text questions like “When was Ada Lovelace
born?” or “Who was born in 1815?”.
