Perhaps you should try some spelling variations:
information agents » information age, information access, information about
taking decision » taking decisions, making decision, making decisions
agents taking » agents taming, agency taking, agent talking
data creating » data cleaning
data testing » data fitting, a testing, data writing
data openg » data open, data peng

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 agents taking decision ((data openg) OR (((data creating) OR (data testing))))~.
• Adding a wildcard symbol may retrieve word variants: information agents taking decision ((data openg) or (((data creating) or (data testing))))*.
