Perhaps you should try some spelling variations:
information agent » information agents, information age, information about
based imprecision » based precision, based imprecise, biased precision
data imprecision » table imprecision, data compression, _ imprecision
data detecting » data detection
data penting » data testing, data getting, data presenting

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

• Performing a fuzzy search may retrieve terms with similar spellings: information agent ((data imprecision) OR (based imprecision)) ((data penting) or (data detecting))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: information agent ((data imprecision) OR (based imprecision)) ((data penting) OR (data detecting)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "information agent ((data imprecision) OR (based imprecision)) ((data penting) or (data detecting))".
• Adding a wildcard symbol may retrieve word variants: information agent ((data imprecision) OR (based imprecision)) ((data penting) or (data detecting))*.
