Trip Report WWW2004
P3: will the semantic web scale ?
- prof. dr. jürgen angele, uni karlsruhe (ja)
- prof. dr. alon y. halevy, transformic (ah)
- prof. dr. ian horrocks, uni manchaster and OWL contributer (ih)
- dr. cathy marshall, microsoft (cm)
there were approximately 150-200 attendees including "tbl".
statements from the panelists:
- cathy marshall:
- semantic web is meta data.
- libraries use meta data.
- it is created by trained people.
- on the web, semantic data is created by anybody - no rules applies.
- alon y. halevy:
- structuring data is hard.
- people find it hard to share data.
- people need a clear return on their investment.
- web: unstructure, easy, simple, meant to share
- semantic data (databases): structured, difficult (requires education), not meant to be shared (privacy)
- jürgen angele:
- OWL does not scale, neither conceptually nor technically.
- the semantic web is a great opportunity, but OWL is a step in the wrong direction.
Q1: what is the return of investments for annotations ?
- ja: deutsche telecom prooves there is a clear roi, at least within closed communities.
- ah: maintenance is expensive
- cm: who get's the cost, who get's the benefit ?
- ih: AI is successfull where information is expensive
- question from the floor: were annotation handmade ?
- ja: yes
- comment from the floor: depends on if the customer will pay for it.
- comment from the floor: same motivation as with open software: re-use existing information
Q2: will the scoial process behind the semantic web scale up ?
- ah: there will be many different ontologies, we need to find ways to cope with that
- cm: do we want everybody (the government) to see our personal data ?
- ah: using the same schema (= onthology) does not garantuee interoperability. many companies use the same SAP schema very differently.
- comment from the floor: if the technic is there, people (companies) will use it.
- comment from the floor: nobody claims that agreeing to a schema will solve all the worlds problem. it's just the next step.
- comment from the floor: just do it and don't spend so much time/energy thinking about what is the best way to do it.
- comment from the floor: it doesn't have to be centralized or distributed - it has to be both.
- comment from the floor: the web is chaotic - onthologies are complex. just let the semantic web evolve.
Q3: is the representation language rich enough ?
- ih: counter-question: are people willing to use it ?
- ja: language is important for providing semantic data
- ah: appling sem to a webpage is more like writing your first program a give it to somebody else to use it.
- comment from the floor: you don't need bright craftmanship to add sem to a webpage. let's start with lightweight sem data and free meta data.
- ih: can we make the semweb good enough to be useful ?
