Aligning standards from different states promises to help teachers in one state find appropriate materials created and cataloged elsewhere. Although such alignments provide a powerful means for crosswalking standards and curriculum across states, alignment matrices are intrinsically sparse. Hence, we hypothesize that such sparseness may cause significant numbers of false negatives when used for searching curriculum. Our preliminary results confirm the false negative hypothesis, demonstrate the usefulness of term-based techniques in addressing the false negative problem, and explore ways to combine term occurrence data with standards correlations.10aAccounting10aBIS1 aMarshall, Byron1 aReitsma, Reindert1 aCyr, Martha, N  u/biblio/semantics-or-standards-curriculum-search-0
