4. Beyond Web 2.0: 2009 Trends Structured / Linked Data - Wolfram Alpha, OpenCalais Real-Time Web - Twitter, FriendFeed Personalization - Facebook, Amazon.com Mobile Web / Augmented Reality - FourSquare, Layer Internet of Things - IBM, Pachube

5. 1. Structured Web Web of Data “ Unstructured information will give way to structured information - paving the road to more intelligent computing.” ( When Sites Become Services ; Alex Iskold, Mar 07) Pages not the center of the Web now, Data and Services are More Than Semantic Web Linked Data Microformats RDFa Curated content (Wolfram|Alpha uses Wikipedia, licensed content, etc) Any type of structured content: XML, CSV files, database

6. Linked Data Linked Data: structured data, but not necessarily semantic W3C Linking Open Data (LOD) project The image illustrates participating data sets as of March 2009. E.g. Thomson Reuters' OpenCalais project, Freebase, and DBpedia Re-uses existing ontologies such as WordNet, FOAF, and SKOS The data sets all grant access to their knowledge bases and link to items of other data sets. The Web of Data: Creating Machine-Accessible Information ; Alexander Korth, Apr 2009

7. Linked Data: Let A Thousand Flowers Bloom Linked Data enables data to be opened up and connected so that people can build interesting new things from it. (via Tim Berners-Lee) Linked Data is Blooming ; Richard MacManus, May 2009 Image credit: Tim Berners-Lee, TED, Feb 09

8. Linked Data: OpenCalais Example: OpenCalais Reuters, the international business and financial news giant, launched an API called OpenCalais in Feb 08.

10. Wolfram Alpha “ computational knowledge engine” Vast repository of curated data from public and licensed sources Sophisticated Natural Language Processing algorithms Search engine-like interface, natural language statements Does computations on data W|A: The Use Cases ; Richard MacManus, July 09 W|A: First Impressions ; Frederic Lardinois, April 09

11. 2. Real-Time Web New form of communication, New body of content, Real time, Public, social graph associated with it, Implicit model of federation. The Real-Time Web: A Primer ; Ken Fromm, Aug 09 A core part of many Internet products this year: Twitter, FriendFeed, Facebook, Google, Delicious, Wordpress, and many others.

Twitter client like TweetDeck, Seesmic or Peoplebrowsr; group people, keywords and topics

15. Open Data The more data about you and your social graph that is available to be used by applications, the better targeted the content and/or service will be to you. APIs, Portable data Making data available on the Web via APIs, web services, open data standards Social Graph Social networks slowly opening up: OpenSocial / Facebook Platform --> Social Graph --> Custom Social Networks? Brad Fitzpatrick: "the global mapping of everybody and how they're related” Thoughts on the Social Graph ; Brad Fitzpatrick, Aug 07 Tim Berners-Lee: Third main "level" of computer networks (Giant Global Graph): Internet --> Web --> Graph. Social Graph & Beyond ; Richard MacManus, Nov 07

Check out DataPortability.org OpenID - portable identity; single sign-on OpenSocial - Google initiative for social networks, enabling developers to create widgets with one set of code; MySpace a member, Facebook isn’t APML - growing ‘Attention’ standard; Your Attention Data is all the information online about what you read, write, share and consume

17. Recommendation Engines Given a set of ratings for a particular user, along with those of the whole user base, come up with new items that this user will like. Personalization is driving it. 4 Approaches: Personalized recommendation - recommend things based on the individual's past behavior Social recommendation - recommend things based on the past behavior of similar users Item recommendation - recommend things based on the item itself A combination of the three approaches above Rethinking Recommendation Engines; Alex Iskold, Feb 08

23. IBM & The Internet of Things Offers a range of RFID and sensor technology solutions IBM & Danish transportation company Container Centralen: sensors as part of the entire travel chain Allows participants to monitor conditions and climate during travel. IBM and IoT ; Richard MacManus, July 09

24. Pachube: Platform for Internet Enabled Environments Pachube (pronounced "PATCH-bay"): lets you tag and share real time sensor data from objects, devices, buildings and environments both physical and virtual. Pachube is about "environments" moreso than "sensors.” Pachube review ; Richard MacManus, May 09
