As humans, we can quickly understand that this data is related to the same thing (ACME company), however it's not so obvious to software, as it generally doesn't have enough context. To use the example data above in apps one needs to resolve the challenges of having different data structures, schemas, means of access - requiring many operations to understand, integrate and validate the datasets. For example, how would you query for the email address of ACME company? This is where the Semantic web helps.
