Information about the meanings of terms in context supports useful
inferences in a variety of language processing and information
retrieval tasks. We hypothesize that much of that information can be
derived from explicit and implicit relationships between terms in the
masses Web content and user interactions with that content. I will
describe initial tests of that hypothesis where we use graph label-
propagation methods to combine many small pieces of evidence from
unstructured and semi-structured Web text to bootstrap broad-coverage
instance-class relationships from a few seed examples.
