The Challenges of Opinion Retrieval
Abstract : Opinion retrieval is concerned with finding documents that are both
relevant and opinionated to a user information need. Information
retrieval (IR) has dealt with relevance for a long time, but opinion
is a more recent issue whose solution seems to go beyond what can be
achieved with the techniques developed in IR. In this talk I will
present some of the challenges that opinion retrieval brings to IR and
show how we can still find acceptable solutions to it within IR,
without resorting to Natural Language Processing techniques that would
not scale up easily.
