Abstract: For the knowledge management in runtime product development business processes,a context-aware workflow knowledge recommending approach was proposed.Based on the investigation of workflow task execution contexts,a hierarchical workflow context ontology model named WfCOM was proposed.Aiming at the common features of elemental and structural levels of WfCOM instances,three algorithms were respectively studied:a linguistic similarity calculation algorithm for string similarity measuring based on Jaro-Winkler,a text vector space similarity calculation approach based on TF-IDF for ontology description,and a structural self-similarity calculation method for context ontologies based on graph theory.Based on the presented ontology matching approaches,a linear combination approach to calculate the multi-dimensional context similarities was proposed,and a weighting vector searching approach was also proposed based on access history of business artifacts,which was then evaluated thereafter by experiments.
