Feature N denote N features extracted from the utterances (we discuss the actual features in the next section), then, we encode these features using soft formulas of the form, Given the MLN specified in the previous section, the inference task is to jointly compute an assignment to all possible groundings of the query predicate, Mode.
we compute this assignment as a solution to the following optimization problem max ω h∈H where H is the set ground atoms of hidden predicates and Q is the set of ground atoms of query predicates, ω is an assignment on all atoms in Q.
