How The Semantic Web Can Boost Africa's Fortunes

In recent years we've seen Facebook go public with a $100 billion valuation and General Motors, formerly the world's biggest company, go effectively bankrupt and need to be bailed out. And hot digital properties like Instagram, SnapChat and WhatsApp have built communities of millions of people in a very short period with very lean resources. We are now witnessing the complete transformation of business models that we knew. Value chains are now being subsumed by value networks. Uber, the taxi replacement service, with a valuation of $50 billion has no cars. Alibaba, an ecommerce outfit, with a valuation of $167 billion has no inventory.
