Myths behind High Frequency Trading

March 5, 2012 by mikeohara   Comments (0)

Recently a Luddite mentality has worked its way into the debates centered around High Frequency Trading and the effect it might, or might not have, on the overall market.  Let’s understand something right away: Not all HFT is the same.  There needs to be a basic understanding of a strategy which now makes up an estimated 50 to 70 percent of overall exchange volume.  It becomes painfully obvious to those of us who are veterans of the industry that there is a basic misunderstanding of what HFT is and how it contributes to the market.  The upcoming anniversary of the ‘flash crash’, which put the entire subject in the spotlight, needs to be understood before ‘new regulations’ are imposed to stop them from happening.  That isn’t to say that nothing should be done, on the contrary, I think there needs to be a coordinated effort by various regulators to enforce certain rules and regulations. (Equities are governed by the SEC while futures are governed by the CFTC) There are predatory programs which need to be understood and monitored and the concept of having a dislocation caused by two different sets of regulations is confusing.

Breaking into the NoSQL Conversation

Rob Gonzalez, Cambridge SemanticsSemantic Web Community: I’m disappointed in us!  Or at least in our group marketing prowess.  We have been failing to capitalize on two major trends that everyone has been talking about and that are directly addressable by Semantic Web technologies!  For shame.

Do-It-Yourself Linked Data?

March 4, 2012 by Jenz514   Comments (0)

Richard Wallis recently posed the question, is do-it-yourself Linked Data a good idea? He states, “Most Semantic Web and Linked Data enthusiasts will tell you that Linked Data is not rocket science, and it is not.  They will tell you that RDF is one of the simplest data forms for describing things, and they are right.  They will tell you that adopting Linked Data makes merging disparate datasets much easier to do, and it does. They will say that publishing persistent globally addressable URIs (identifiers) for your things and concepts will make it easier for others to reference and share them, it will.” continued…

Making Hotel Websites Semantic

March 4, 2012 by Jenz514   Comments (0)

Larry Smith of Thematix recently discussed the potential value of adding semantic technology to hotel websites. He writes, “A hotel is dynamic — a veritable revolving door of people and activities. Yet most hotel websites are dynamic only in the booking process. It’s a rare hotel that understands that you are checking in for a reason, and that that reason is probably something happening in the hotel or nearby, like a conference, meeting, sightseeing attraction, wedding or a family reunion. Using your hotel website to share information about local news, conferences, tradeshows, concerts, theater, attractions and the like will not only yield greater guest satisfaction and convenience; it can yield very substantial marketing and social presence.” continued…
