Perhaps you should try some spelling variations:
information interaction » information integration, information interacting, information extraction
interaction models » interaction model
models rules » model rules, models role, model rule
array string » array strong, arrays strings, array sharing
array fermi » array forming, array format
array using » arrays using

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: information interaction models rules ((((array string) OR (array fermi))) OR (array using)).
• Adding a wildcard symbol may retrieve word variants: information interaction models rules ((((array string) or (array fermi))) or (array using))*.
