We anticipate that progress in development of the Semantic Web will take place by: 1. Moving along the semantic continuum from less clearly specified (implicit) semantics to more clearly specified (formal) semantics. 2. Reducing the amount of hardwiring that is necessary, and/or changing which parts are hardwired and which are not. This will entail a corresponding increase in the amount of automated inference to infer the meaning of Web content, thus enabling agents on the Semantic Web to do correctly perform their tasks. The importance of compelling use cases to drive the demand for this cannot be underestimated. 3. Increasing the amount of public standards and agreements, thus reducing the negative impact of today’s pervasive heterogeneities. 4. Developing technologies for semantic mapping and translation for the many cases where integration is necessary, but it is not possible to reach agreements.
