2 Watson的体系结构

3 Watson的体系结构 … Each stage admits multiple implementations that can produce alternative results. At each stage, alternatives are independently pursued as part of a massively parallel computation. DeepQA never assumes that any component perfectly understands the question and can just look up the right answer in a database. Rather, many candidate answers are proposed by searching many different resources, on the basis of different interpretations of the question and category. A commitment to any one answer is deferred while more and more evidence is gathered and analyzed for each answer and each alternative path through the system. …

4 优势 技术研发 One approach does not fit all. 项目管理 并行化、松耦合的组织方式更可行。
