This paper presents a multiple knowledge spaces creation process for domain oriented semantic associative search. We have presented a generation method of semantic associative search spaces for domain-specific research areas. This process enables database managers and experts of the specific domain to collaborate in constructing semantic search spaces with domain-oriented knowledge. Domain-specific knowledge space creation is essentially important to obtain appropriate knowledge from expert-level document repositories. This paper presents the implementation process for knowledge space creation and the software environment for supporting collaboration work between database managers and domain experts.
