Re: Is scalability the key property of knowlege graph?

Besides，I’m building some kg for  Electronic Commerce which contain billions of goods and serve billions of people. In fact the first  difficult problem is to figure out what can we do with KG and what kind of issues KG can solve.

So is it necessary to open a scalable  and standard knowledge vault so that everyone can keep extended it and make it more perfect just like linux kernel or  wiki pedia? What kind of knowledge should be contained in the standard knowledge vault so that it can be universal?

In this way ,the compute can directly know nature language, and human can communicate with compute with nature language, also a compute can communicate with another compute with nature language.
