Surface manufacturing is a process of adding material to or removing material from the surfaces of a part, where industrial robots are usually used. Robot programming for these applications is still time consuming and costly. Typical teaching methods are not cost effective and efficient. There are many offline programming methods developed to reduce the robot programming effort. However, these methods...
As the information grows exponentially, it has become a new and basic requirement to reduce the querying area efficiently and accurately for information querying. This paper proposes a semantic distance based clustering algorithm for XML documents. It discusses the algorithm in two steps. Firstly, it forms some DTD clusters with all heterogeneous DTD documents by using the global semantic dictionary...
To enable accessing deep web information at semantic level, this paper develops a semantic query rewriting mechanism on heterogeneous database enabled web information system with complex ontology mapping technology. It discusses the procedure of converting database schema and instances to ontologies at first, and then the patterns of complex ontology mappings, and the ontology-based query planning...
