Mashups in the Middle – Bridging the Gap to the Semantic Web

Posted in ImplicitWeb, Mashups, SemanticWeb at 9:45 am by elliot

Yesterday brought an enlightening post by Alex Iskold, entitled “Top-Down: A New Approach to the Semantic Web“:

“While the original vision of the semantic web is grandiose and inspiring in practice it has been difficult to achieve because of the engineering, scientific and business challenges. The lack of specific and simple consumer focus makes it mostly an academic exercise.”

The post touches upon some of the practical issues keeping semantic technology out of the hands of end-users, and potential ways around these roadblocks. Summaries are given for three top-down “mechanisms” that may provide workarounds to some issues:

  • Leveraging Existing Information
  • Using Simple / Vertical Semantics
  • Creating Pragmatic / Consumer-Centric Apps.

I can’t agree more with the underlying principle of this post: top-down approaches are necessary in order to expose end-users to semantic search & discovery (at least in the near-term).

However, this isn’t to say that there isn’t value in bottom-up semantic web technologies like RDF, OWL, etc. On the contrary, these technologies can provide extremely high quality data, such as categorization information. In the past year, there’s been significant growth in the amount of bottom-up data that’s available. This includes things like the RDF conversion of Wikipedia structured data (DBpedia), the US Census, and other sources. Indeed, the “W3C Linking Open Data” project is working on interlinking these various bottom-up sources, further increasing their value for semantic web applications. What’s the point of all this data collection/linking? “It’s all about enabling connections and network effects.”

My personal feeling is that neither a bottom-up or top-down approach will attain complete “success” in facilitating the semantic web. Top-down approaches are good enough for some applications, but sometimes generate dirty results (incorrect categorizations, etc.) Bottom-up approaches can generate some incredible results when operating within a limited domain, but can’t deal with messy data. What’s needed is a “bridging the gap” between the two modes: leveraging top-down approaches for initial dirty classification, and incorporating cleaner bottom-up sources when they’re available.

So how do we bridge the gap? Here’s what I’m betting on: Process-oriented, or agent-based mashups. These sit between the top-down and bottom-up stacks, filtering/merging/sorting/classifying information. More on this soon.

Company Website / Tech. Preview Launch

Posted in ImplicitWeb, Mashups, Orchestr8 at 11:49 am by elliot

My company (Orchestr8) launched its corporate website today:

We’re letting a select number of individuals take a “first look” at our AlchemyPoint platform in the form of a Technology Preview. We’re looking for user feedback to help us expand and improve the AlchemyPoint system before its final release.

Access to the Technology Preview is being provided in a staged fashion with priority given to users who apply first, so sign up today!

Please note: The AlchemyPoint Technology Preview is pre-Beta software. It may contain software bugs or other limitations.
