Extract:

Introduction to "This is Watson" is about IBM Watson, the open-domain question-answering system.

The paper argues that such systems require advances in areas of

The Watson system (AdaptWatson) consists of "more than 100 core algorithmic components."

Some of the components are:

  • Question analysis to determine lexical answer type
  • Grammatical parser of the question.
  • Collection of content, e.g., from encyclopedias.
  • Building a resource (PRISMATIC) with knowledge from collected content.

[edit] Results

Initial performance was 16% precision@70 (i.e., with 70% questions answered). It rose to 85% Precision@70.
