annotateTree

public void annotateTree(HAWKQuestion q)

annotateNouns

private void annotateNouns(MutableTree tree)

"Nouns are often referring to classes, while sometimes to properties, thus two lexical entries are built { one containing a semantic representation with a class slot and one containing a semantic representation with a property slot." citation by Unger et al. tbsl

annotateVerbs

private void annotateVerbs(MutableTree tree)

"Verbs most often refer to properties, thus a lexical entry with a property slot is built. However, in some cases, the verb does not contribute anything to the query structure (like have in Which cities have more than 2 million inhabitants?), thus an additional entry is built, that does not contain a property slot corresponding to the verb but assumes that the property slot is contributed by a noun (inhabitants in this case)." citation by Unger et al. tbsl

rank

private List<String> rank(List<String> search)

annotateProjectionLeftTree

private void annotateProjectionLeftTree(MutableTree tree)

this method annotates the left-most child of the root and uses the inline commented heuristics to annotate the tree
