Abstract. Since its birth in 1995, Wiki has become more and more popular. This paper presents a Semantic Wiki, a Wiki extended to include the ideas of Semantic Web. The proposed Semantic Wiki uses a simple Wiki syntax to write labeled links which represent RDF triples. By enabling the writing of labeled links, Semantic Wiki may provide an easy-to-use and flexible environment for an integrated management of content and metadata, so that Semantic Wiki may be used as a lightweight knowledge management system.

In this paper, a manufacturing feature recognition method for the generation of multiple process plans is proposed. The feature recognition method is constructed in 2 phases. First, features are extracted using Extended Super Relation Graph (Extended SRG) Method. By using Extended SRG Method, interacting and overlapping features can be extracted in several different ways, corresponding with different kind of machining operations. In the second phase, the authors organize the extracted features into manufacturing feature sets using Feature Spatial Relation (FSR) Method. By organizing features into multiple manufacturing feature sets, the generation of multiple process plans is made possible, since each manufacturing feature set corresponds with different kind of process plans. In this paper, the authors describe the Extended SRG Method and FSR Method. The authors use a case study to clarify the effectiveness of these methods for the manufacturing feature sets creation.

In this paper, the creation of ontology of manufacturing features for the development of a feature library is described. The designer's intention described in functional data of the feature constructing face elements is considered for the creation of the ontology. The creation of the manufacturing feature ontology is intended to make the feature library be useful for the extraction of manufacturing information for process plans generation.
