Perhaps you should try some spelling variations:
communication context » communication contexts, communication content, communicative context
communities dimension » communities dimensions, community dimension, communities extensions
context communities » contexts communities, content communities, context community
shared spaces » shared space, shared stocks
tuple spaces » tuple space, type spaces, triple space
use spaces » phase spaces, gauge spaces, whose spaces

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

• Performing a fuzzy search may retrieve terms with similar spellings: communication context communities dimension ((tuple spaces) or (((shared spaces) or (use spaces))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication context communities dimension ((tuple spaces) OR (((shared spaces) OR (use spaces)))).
• Adding a wildcard symbol may retrieve word variants: communication context communities dimension ((tuple spaces) or (((shared spaces) or (use spaces))))*.
