Hakia is a general purpose semantic search engine, as opposed to e.g. Powerset and Cognition (below), that search structured corpora (text) like Wikipedia.
The presentation of the search results is less than perfect, though, and I wish the cognition team would learn from Hakia or Powerset in this regard.
我认为我对Cognition搜索结果的表述还不是很完善，但是我殷切地希望Conition团队也可以借鉴一下Hakia或者Powerset的经验。
Not all of the summaries are informative or even intelligible, but that is likely to improve; like Hakia, SenseBot is in beta.
也不是所有的总结都是信息广泛或者容易理解的，但却是极有可能被改进的。Hakia,SenseBot都还在测试阶段。
