24. The computer program product of claim 23 , wherein the first entity corresponds to a market research project, the second entity corresponds to a panelist, the fact vertices correspond to profile parameter vertices representing profile parameter values identified for the panelist, and the criteria vertices represent quota cells of market research projects.
23. A computer program product, comprising: a non-transitory computer-readable medium, comprising: code for identifying one or more fact vertices for the second entity; code for generating a first set of criteria vertices by traversing a graph database constrained to the fact vertices identified for the second entity, wherein the graph database relates fact vertices to criteria vertices by edges corresponding to a Boolean expression for matching the first entity to the second entity; and for a first criteria vertex in the first set of criteria vertices: code for determining whether the first criteria vertex matches a first fact vertex among the fact vertices identified for the second entity, in response to determining the first criteria vertex matches the first fact vertex, code for assembling a second set of criteria vertices by adding the first criteria vertex to the second set of criteria vertices, or in response to determining the first criteria vertex does not match a fact vertex among the fact vertices identified for the second entity, code for retaining the second set of criteria vertices, code for determining whether the second set of criteria vertices completes the Boolean expression, and in response to determining the second set of criteria vertices completes the Boolean expression, code for completing the assembly of the second set of criteria vertices, or in response to determining the second set of criteria vertices does not complete the Boolean expression, code for processing a second criteria vertex in the first set of criteria vertices, wherein completion of an include criteria of the Boolean expression is determined separately from completion of an exclude criteria of the Boolean expression.
