The Semantic Web is an evolving extension of the World Wide Web in which the semantics of information and services on the web is defined, making it possible for the web to understand and satisfy the requests of people and machines to use the web content.
it just means that they are facilitating the sourcing of data. semantics is defined in a dictionary as related to different meanings of words; maybe their expanded suggestion list can be better classified as semantic refinements.
