This expansion of the graphic components (as opposed to the typical expansion of the query) accomplishes two objectives: 1) it addresses the problem of
sparse graphic text by adding semantically similar words, and 2) it addresses
the problem of terms in the query capturing general classes (such as car or automobile) when the graphic instead contains an enumeration of members of that
general class. If the expanded text of an infographic contains at least one of the
query noun words, this infographic is preselected for further rank-ordering.
