An investor or analyst is trying to track a company that produces cellphones, lets say. Months ago there was published information that semantically linked their target company with a battery producer in China. If news today comes out talking about riots or unrest at Lithium brine pools in that area in China, it might have a direct impact on the supply line of their target company. The goal is to have the intelligent ability to follow the relationship chain to deduce Lithium brine pools -supports-> battery producer -supports-> cellphone manufacturer. It can then surface the Lithium brine pool article as of high importance to them. Semantic tagging alone falls far short of this ability.
