With continuing investment in (and acquisition of) companies for whom semantic technologies are a key part of their proposition, we explore the extent to which investors are interested in "semantic technology" per se, and look at recent investments from Union Square Ventures to illustrate the wider discussion. A number of entrants to this year's TechCrunch 50 event feature a semantic technology focus, and we also look at these with the help of Union Square's Brad Burnham, TechCrunch's Erick Schonfeld, and VentureBeat's Chris Morrison.
