Semantic-based web service discovery and chaining for building an Arctic spatial data infrastructure

摘要: Increasing interests in a global environment and climate change have led to studies focused on the changes multinational Arctic region. To facilitate research, spatial data infrastructure (SDI), where data, information, services are shared integrated seamless manner, particularly light of today's scenarios, is urgently needed. In this paper, we utilize knowledge-based approach web portal technology prototype an SDI (ASDI) by proposing (1) hybrid for efficient service discovery from distributed catalogs dynamic Internet; (2) domain knowledge base model latent semantic relationships among scientific services; (3) intelligent logic reasoning mechanism (semi-)automatic selection chaining. A study influence solid water dynamics bio-habitat region used as example demonstrate prototype.
