Ontology-based Scientific Data Service Composition: A Query Rewriting-based Approach.
Linhua Zhou, Huajun Chen, Tong Yu, Jun Ma, Zhaohui Wu · 2008
Modern scientific research is generating daunting amount of data that is commonly required to be combined together to service daily research endeavors. This paper introduces an ontology-based approach to publishing and composing data-intensive web service. The approach distinguishes itself by its capability of dynamically evolving service interface and a query rewriting-based planner for service composition, en-abled by richly describing service capability using the seman-tic web languages. The advantage of the proposed approach is that the data service can adapt itself with client request dy-namically, greatly improving its query service capability. The evaluation reveals the approach scale well as service number goes large.
