Semantic Web Trust Layer

golbeck: Chris Bitzer, Jeremy Carroll
golbeck: (stand in link)
golbeck: Trust mechanisms: Reputation Based, Context-based, Content-based
golbeck: Drawback of Reputation-based mechanisms only work if you have enough ratings
golbeck: Context based trust mechanisms use background information about the information provider
golbeck: Content-based Trust Mechanisms use content itself, together with related information content published by other information providers
golbeck: Chriz Bitzer refers to Alien Cow example
golbeck: Jeremy goes into Named Graphs, Abstract Syntax
golbeck: Lots of symbols and such =)
golbeck: Jeremy presents vocabulary for Sem Web publishing

Tucana & Kowari - Massive Scalability for RDF Storage...

mattb: Kowari (open source storage system)
pshab: David Wood & Tom Adams
mattb: their storage system is java based, has jena interface
mattb: compared to tucana, kowari has no security, api support and documentation are less developed, data types are limited, etc
areggiori: Kowari design notes
areggiori: Tucana white paper about A new type of Data Management mentions 'phase-trees'
mattb: tucana defense clients are generating millions of triples (about people, places, etc) via automatic extraction from freetext
areggiori: from the paper "...The Tucana Knowledge Server uses phase treees, so updates do not effect read operations already in progress. This allows long-running transactions...." - me can not find any goolg ref to 'phase-trees' anyway
areggiori: AVL trees
pshab: big companies using Tucana for knowledge management, adaptive monitoring - need for flexible schemas, genoics reserch - analysis of data in schema hell...
pshab: ... defense data analysis...

Donovan Artz from USC Presents Trellis in Trust Session II

golbeck: Trusting information sources
golbeck: Try using trellis
golbeck: Users declare statemens and sources, connectives are formed between statements and sources, and using connectives, statements can be used to reach a conclusion or dismissed in reaching a conclusion.
golbeck: Trellis is demoed to show the average high tempreature in NYC in May.
golbeck: Statements pulled from each source about the average temperature
golbeck: We conclude a statement to be true, and then connect it with other statements that support it, and link it to statements that contradict it.
golbeck: This lets us know which data is correct and which is wrong
golbeck: Then, we can rate sources based on weather or not they gave accurate information

Simile Project

pshab: Stefano Mazzocchi & Ryan Lee
dajobe: longwell browser, knowle
dajobe: datasets ARTStor (not public), MIT openware, wikipedia, CIA world fact book
dajobe: overlap in data is mostly in literals
dajobe: over 400K triples, xslt2 as xml to rdf bridge
dajobe: Ryan Lee demos Longwell
dajobe: the faceted browser
pshab: there is a demo with other data at
dajobe: knowle browser is more of an rdf-like brwoser, all the properties visible - for people who understand rdf
dajobe: Ryan - not an art geek, data not interesting to me
dajobe: so over to W3C Tech Reports. woo
pshab: see the link above to demo
dajobe: and now trying foaf
dajobe: simile arch
dajobe: jena rdf, velocity template system, glue
dajobe: and lucene free text
dajobe: longwell sources available today
dajobe: and knowle
dajobe: 71M download

SemWeb Track - Paul Ford - Harper's a Semantic Web Study

dajobe: semweb track for devday
dajobe: small lefty non-profit magazine
mattb: website
dajobe: not full-text content (yet)
dajobe: lots of linky content
dajobe: articles peppered with links to say, "donald rumsfeld"
dajobe: links to a page in a taxonomy on DR
dajobe: ordered into a timeline
dajobe: plus every fact in the Harpers' Index
dajobe: at the bottom, "DR is a human being, ... is a part of. .. is a part of " plus related, navigfations, perm url
dajobe: clicks on supervisors, top two items Allah, God
dajobe: audience laughs
dajobe: PF - yes, this is the point. This is Harper's reality
dajobe: God supervises Jesus Christ, who supervises GWB
dajobe: "harper's-ish view of the world"

mattb: supervisors, human beings
dajobe: lots of politics involved, on it's sleeve in this mag
dajobe: turned up to 11
dajobe: under the hood, a big pile of XML
mattb: built with XSLT2 operating on an in-memory triplestore
mattb: XSLT2 not really recommended for this sort of work but very familiar to the speaker
mattb: toolkit: vi, emacs, bbedit, cvs, xslt2
dajobe: from 300 real page content to 1100 pages of remixed
dajobe: real viewer/reader benefits
mattb: philosophy of markup: not using RDF directly, but ability to convert to RDF is the 'gold standard' check that the XML is adequate
