The presentation addressed, inter alia, the lack of excitement about semantic web. My key takeaway from his talk was that semantic web is about networking knowledge for the benefit of PEOPLE. I think in getting caught up describing things in terms of computers being able to process information on sites thought use of various standards (not of interest to anyone except the technical community) etc we have lost the focus on the fact that what we really want is more collaboration, more productivity, more discoveries. Semantic web initiatives have an end game of helping people make more use of the information.
Just looked at a nice 3 minute video from Binaryplex – promoting their beta product Hivemind. I do not know what the underlying technologies are. They do not even mention the worked ‘semantics’ in their three minutes. But what it is about is helping people to find expertise and, more importantly, experts in an organisation. Recognising that people, for any number of reasons, may not update their profiles within an organisation the product seeks to address this gap, in the background.
