Comparing OpenStreetmap vs. google maps

 

… an interesting tool that allows a visual comparison of the coverage of various maps, e.g. google maps vs. open streetmap (OSM). Based on people’s enthusiasm, in many (local) places the OSM coverage is much deeper/exacter. However, with respect to quality necessary for routing and navigation applications, OSM in its current status will not be sufficient.

The tool for comparison is available at 

http://tools.geofabrik.de/mc/?mt0=googlemap&mt1=mapnik&lon=0.00012&lat=0.00043&zoom=17

it points at Techno-Z, home of Salzburg Research. One can see that buildings, local paths, etc. are covered much better in OSM than in google maps. Still, this is what we as human users interpret; software/machine readability can be – and is! – quite different.

Salzburg Research passes ISO 9001:2000 audit

ISO 9001:2000 is an international standard that has its origins in assessing suppliers for technical systems. Salzburg Research today successfully passed the audit (by TÜV Österreich). 

I believe that the following three main points argue for a quality management system:

  1. With a QM-System you define rules about processes and interactions; also, these rules are the same throughout the organisation
  2. Knowledge is embedded within an organisation (we all know that this is only possible to a limited degree, but anyway)
  3. Finally, it is a documentation to the outside world (both customers as well as owner) that Salzburg Research is standing for quality 

On the negative side there is – obviously – some overhead in necessary documentation and also, you may loose some degrees of freedom/individuality.

FYI: Five Innovations that will change our live in five years

… is IMHO a pretty cool initiative by IBM.

Here we go:

  • Energy saving solar technology will be built into asphalt, paint and windows
  • You will have a crystal ball for your health
  • You will talk to the Web . . . and the Web will talk back
  • You will have your own digital shopping assistants
  • Forgetting will become a distant memory

The Future Internet

This afternoon, we had a discussion initiated by the Salzburg Global Seminar/Institute for Strategic Dialogue on the future of the Internet.

One of the issues is to define the scope of “future”, i.e., are we talking 10 years, 20 years, etc.? IMHO I believe that for applied research already 5 years is a pretty long period.

Anyway, there is a nice publication (in German only) by the Feldafinger-Kreis: “Trends, Technologies and Applications”. They argue for the following trends

  1. Peer-to-Peer Networking
  2. Embedded Software-intensive Systems
  3. Security and Safety / Privacy / Self-Defending
  4. Semantic Technologies
  5. Knowledge Management
  6. Intelligent Software-Agents
  7. Service Grids in the Internet of Services
  8. Intelligent Resource Management
  9. Self-Managed Systems
  10. e-Processes
  11. Internet of Things
  12. Mobility / Networked Vehicles
  13. Ambient Assisted Living
  14. Human-Computer Interaction

As far as our own work is concerned, I think that the following items are of particular interest to our research

  • the Internet of things (we were talking about all-Ip building infrastructure)
  • ambient assistance
  • realtime geography/mobile systems
  • semantic technologies

Also, in March 2008 the European Commission hosted an event in Slovenia on the Future Internet, see the following URL http://www.fi-bled.eu/ and a short video:

5th anniversary of Salzburg NewMediaLab

logo of Salzburg NewMediaLab, a competence centre on New Media Technologies Today we celebrated the fifth anniversary of Salzburg NewMediaLab, a so-called industrial competence centre (it was the first competence centre in Salzburg). Peter Reiser principial field technologist of Sun Microsystems gave an excellent key note on community equity. See http://www.slideshare.net/peterreiser/how-to-build-vibrant-communities-presentation?type=powerpoint for the slides.

The key messages I personally took from his talk

  • He really believes in sharing vs. ownership of knowledge (sharing is power vs. knowledge is power)
  • He argued that there was a shift from “know-how” to “know-how knows how”
  • and he believes that IT-support for processes will be less important. Which is probably the only thing in his talk that I would agree with.

BTW: Salzburg Research has a strong relationship wih Sun Microsystems. We hosted a SunTREC, an AAJC, got awarded a Sun Center of Excellence for map-based online participation and we are in the process of establishing a follow-up agreement for a CoE for a “Mobility Lab – A Lab on Engineering of Location-based Systems”.

EIT – first steps

The European Institute of Innovation and Technology EIT is taking shape. The constitutive meeting took place in Budapest, September 15th. The first research themes to be worked on in KICs (Knowledge and Innovation Communities) are climate change, renewable energies and the next generation of information and communication technologies.

Basically, any funding in research (fundamental as well as applied) will help in achieving the Lisbon objective and will make Europe more competive. Hower, I am not convinced whether EIT will have impact (in a broad sense on the community) and/or how it will be sustainable.

5. Salzburger Medientag

No. 5! Plattform Digitales Salzburg (University, FH Salzburg and Salzburg Research) have organised the Salzburg Media Day. This year’s theme was “HDTV?!“.

The event took place in connection with “Futura“, a trade fair mainly on consumer electronics.

Red Bull Media House did quite an impressive demo of 3D HDTV; but also the other contributions (Sven Jansel on the Blu-Ray Disk, Herbert Stranzinger Salzburg AG’s portfolio on cable-based HDTV, the ORF’s HDTV trial at EURO 2008, and some others) were very well worth visiting!

Looking forward to 2009!

Success Review of Semway

semway logoToday, we had a successful review of Semway, a project dealing with adding high-level semantics to navigation systems so that they are (more/better) suitable for pedestrians. Karl Rehrl is Semway’s project manager.

What I like about this project: it innovates something that we believe is already working (i.e., navigation systems) in a radically new way so that we can use navigation systems also as pedestrians, or as hikers, ski-tourers, etc. As humans we simply do not navigate according to geo-coordinates but much more with landmarks; we can walk through parks, along rivers, etc.

The main issue I see is in providing/generating semantically enhanced content (btw: the same is true for many semantic web applications as well) so that Semway’s features can be exploited. Besides technological approaches such as text-mining (from existing sources) and others, a community-based approach as is done in openstreetmap.org would be an option.

Atomic Austria is industrial partner in Semway; the project is mainly funded by FFG/BMVIT.

The Semantic Web explained by Nova Spivack

My colleague Andreas Gruber pointed me to a great presentation by Nova Spivack entitled „making sense of the semantic web“. It is available here http://thenextweb.org/2008/06/03/video-nova-spivack-making-sense-of-the-semantic-web/. Nova is founder and CEO of Radar networks, producer of twine.

Here are some comments I took from that lecture. Summaries and (other) comments are available by Erich Schonfeld at http://www.techcrunch.com/2008/04/25/is-keyword-search-about-to-hit-its-breaking-point/ and Anne Helmond at http://thenextweb.org/2008/04/03/nova-spivack-the-semantic-web-as-an-open-and-less-evil-web/:

According to Nova, the Semantic Web is about connecting „everything“, i.e., concepts, things, words, etc. more than a social graph. Saying that “Joe” is of type “Person” and “Palo Alto” is of type “city”. This is not just a hyperlink.

Web 3.0 starts a new decade, the 3rd decade of the Web. It is about enriching the structure of the web, transforming the web form something that’s more like a fileserver to something that’s more like a database.

The 1st era was that of the PC: focused on the frontend. The Web 1.0 focused on the backend; Web 2.0 focuses on the frontend again (AJAX, etc.); Web 3.0 will be backend again. Like a pendulum that swings back. Web 3.0 is a fundamental upgrade to the infrastructure of the web.

Web 4.0 (the fourth decade) will be smarter interfaces and smarter tools, smarter user experience.

According to Nova, there are five approaches for bringing intelligence to the web:

  1. Tagging: very easy to do (which is a pro and a con). Tags at the end of the day are meaningless, e.g. the same person will tag things differently in different situation. One needs a large data set for making sense out of tags.
  2. Statistical approach: what e.g. google does, very stable, does not add semantics
  3. Linguistic approach: trying to actually understanding the meaning of text; is very computationally intensive, hard to scale, etc.
  4. Semantic Web approach: set of open standards by the W3C, i.e., using meta-data to describe the meaning of data; the use of meta data is open to all applications; needs tools, needs someone who creates the metadata, …
  5. Artificial intelligence: software that really thinks, it will take at least some more decades, scalability is a big issue, etc. AI will be huge in Web 4.0. Cycorp is working on such an approach for the last 15 years or so.

The question is whether you make software smarter or data smarter (or both). The Semantic Web is a kind of compromise.

There are two types of approaches to achieve this:

  • Everyone is going to manually create semantic web content (bottom up).
  • Today, we generate RDF, OWL, etc. (semi-)automatically using tools (top down).

Sun says: The network is the computer. Nova says: The Web is the database!

Smart data is data that carries what is needed to make sense of it. The data is self-describing. This allows you to write “dumb software”, i.e., with a general piece of software that you put at medical data will allow you to give medical advice.

We are not trying to replace human intelligence. Machines are good at number crunching; this is what they should do. Humans are intelligent, we need to assist the humans with machines, i.e., computers in the semantic web.

Just-in-time-data is another concept. The semantic web provides the basis for it by using ontologies (like schemas in DBMSs) to achieve that.

The WebOS is coming. The WebOS needs a file system, the semantic web is a candidate for that. With the semantic web we add an open database layer on top of today’s web.

Standards are important: RDF, OWL (built on RDF), SPARQL (SQL for RDF), SWRL (a rule language), GRDDL -> see the W3C site for details.

“DataWeb” as better term for Semantic Web; with triple stores as new types of databases (based on e.g. relational DBMSs) to manage (the large) lists of triples. Scales better on the web.

Geo-names, music-names, sioc, etc. and many more ontologies and connected data do already exist.

Right now still in early adoption of this period. 007-2009 as first wave, a couple of million end-users in their day-to-day- live. twine, freebase, etc.

FOAF; SIOC; are good places to start.

Questions

  • Does the semantic web offer any new business models? The semantic web does not introduce any new business models (in addition to the existing ones such as search, advertise, media & content, …) but it makes things smarter. But the semantic web allows new players to come into the market.
  • Openness? if your business is about being evil, will you do better with the semantic web? It will be more difficult for you, because the semantic web will generate data that is self-descriptive; i.e. lock-in strategies will be harder to achieve.
  • I have heard in the year 2000 about the semantic web. Now it’s 2008 and it is still not there. Will it – and when – take off? We often forget that there was 15 years of research in hypertext, protocols, etc. before we could use the web in the early 90ies. We often forget about that. The same (and probably a longer period) will be necessary for the semantic web.
  • How do you address global definitions? Good question! The semantic web does not require a global definition. The semantic web was designed for disagreement. Therefore, the problem is that there may be many definitions. Hence, the standards were built to include a mechanism to create mappings to define equivalences, etc. The winners will be the ones that have the content that lead the definitions of the standards AND have the data.
