4. What does Vulcan do
4
Vulcan Inc. was established in 1986 by investor and philanthropist Paul G. Allen, co-founder of Microsoft, to manage his business and philanthropic efforts. Allen is chairman of Vulcan and his sister, Jody Allen, is president and CEO.
5. It all began with a vision

6. Now the Vision Continues as Project Halo

Automatic Question Answering System
Project Halo is a staged, long-range research effort by Vulcan Inc. towards the development of a "Digital Aristotle"a reasoning system capable of answering novel questions and solving advanced problems in a broad range of scientific disciplines and related human affairs. The project focuses on creating two primary functions: a tutor capable of instructing and assessing students in those subjects, and a research assistant with broad, interdisciplinary skills to help scientists and others in their work.
7. Project Halos Focus Areas

Knowledge Acquisition
Plus other related semantic technologies and commercial efforts

Wikis and Semantic Wikis
Crowdsourcing and Consensus on Data
Semantic MediaWiki and its Extensions
Wiki-based Knowledge Management on a Larger Scale
Enterprise Knowledge Management
Semantic Encyclopedia
Evolving as a Web Application Development Platform
Examples: Semantic Football, Agile Project Management
12. A Key Feature of Wiki
12
Consensus
This distinguishes wikis from other publication tools
13. Consensus in Wikis Comes from
Collaboration
~17 edits/page on average in Wikipedia (with high variance)
Wikipedias Neutral Point of View
Convention
Users follow customs and conventions to engage with articles effectively
13
14. Software Support Makes Wikis Successful
Trivial to editby anyone
Tracking of all changes, one-step rollback
Every article has a Talk page for discussion
Notification facility allows anyone to watch an article
Sufficient security on pages, logins can be required
A hierarchy of administrators, gardeners, and editors
Software Bots recognize certain kinds of vandalism and auto-revert, or recognize articles that need work, and flag them for editors
14
15. Finding Deeper Info
Wikipedia has articles about

  • all cities with info on their populations, locations and skyscrapers, etc.

all German cars with engine size, accelerating data
Can you find:
Skyscrapers with 50+ floors and built after 2000 in Shanghai (or Chinese cities with 1,000,000+ people)?
Or German(Porsche) cars that accelerate from 0-100km/h in 5 seconds?
15
16. How Wikipedia Answers List!

17. Going Deeper

19. And Deeper

20. And Now

21. Look into List in Wikipedia

22. Editing Standard Wiki Article Static List

23. Static List, Tables, ,Not Useable Enough

24. Semantics Come To Rescue
To find answers like:

  • All Porsche vehicles made in Germany that accelerate from 1-100 km/h less than 4 seconds

25. Sci-Fi movies made after year 2000 that cost less than $10M and gross more than $30M 26. A map showing where all Mercedes-Benz vehicles are manufactured 27. All skyscrapers in China (Japan, Thailand,) of 50 (40/60/70) floors or more, and built in year 2000 (2001/2002) and after, sorted by built year, floors, grouped by cities, regions 28. And many moreWe need
structured data

and consistent

29. What is a Semantic Wiki
Awikithat has an underlyingmodel of the knowledge described in its pages.
To allow users to make their knowledge explicit and formal

32. List of Semantic Wikis
AceWiki
ArtificialMemory
Wagn-Ruby on Rails-based
KiWi Knowledge in a Wiki
Knoodl Semantic Collaboration tool and application platform
Metaweb- the software that powersFreebase
OntoWiki
OpenRecord
PhpWiki
Semantic MediaWiki- an extension toMediaWikithat turns it into a semantic wiki
Swirrl- aspreadsheet-based semantic wiki application
TaOPis- has a semantic wiki subsystem based on Frame logic
TikiWikiCMS/Groupware integratesSemantic linksas a core feature
zAgile Wikidsmart- semantically enablesConfluence

33. Basics of Semantic Wikis
Still a wiki, with regular wiki features
Category/Tags, Namespaces, Title, Versioning, ...
Typed Content (built-ins + user created, e.g. categories)
Page/Card, Date, Number, URL/Email, String,
Typed Links (e.g. properties)
capital_of, contains, born_in
Querying Interface Support
E.g. [[Category:Member]] [[Age::50]]
[[Year built::
