Perhaps you should try some spelling variations:
communication context » communication contexts, communication content, communicative context
context contextual » context conceptual, context context, context content
tuple spaces » tuple space, triple space
shape spaces » shape space, shared spaces, state spaces
type spaces » state 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 contextual dimensions ((((tuple spaces) or (type spaces))) or (shape spaces))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication context contextual dimensions ((((tuple spaces) OR (type spaces))) OR (shape spaces)).
• Adding a wildcard symbol may retrieve word variants: communication context contextual dimensions ((((tuple spaces) or (type spaces))) or (shape spaces))*.
