The naymz hype - should I?

I am getting invitation after invitation for naymz.com. Now, what do they do that is related to us?

It is a web 2.0 application similar to facebook or linkedin, giving you the opportunity to manage a social network and get a good-googleable personal website. It somehow is a freebase/sindice for the web2.0 when it comes to the question of "identity".

My name is already pretty well googleable, so I wonder if I need naymz. Also, their homepage is a bit search-engine optimized. If you go to www.naymz.com, you find a "directory" of links on the lower half of the page and links to entry points, if I click their lawyer directory the first hit is a search engine optimization marketeer. I hesitate a little to join a club that is so optimized on search engines, and not on content. If I google for images on "leo kaiserslautern" it works well, so you could search-engine optimize without having these index-links on the frontpage. Hm.

Techcrunch said two years ago that the company has five employees and has taken an angel investment of $250,000. So they used that to build up a rather complete app, and I guess they already are in second or third VC round. But I don't find more news about them on techcrunch.

Now I say I don't join because I don't need it and I see their "front-page" spamming a bit spooky, what do you think about it? Did anyone read their privacy statement/contracts? Please Comment...

Hi Leo,

I think Naymz runs a pretty good business- but as you said, it depends what you need them for.

I suggest you also take a look at LookupPage. They're more into helping people enhance their professional web-presence, as opposed to social-networking.

And don't be concerned about seeing SEO markers on websites- it's just a sign that the website is doing all it can to help its users market themselves.

btw, gnowsis is not part of KDE - but its a good idea :-)

Due to current rumour that appears on the net and in chats around me because of my talk on wednesday at ISWC: gnowsis is not part of KDE. But nepomuk-kde is part of kde.

its all a bit complex: gnowsis was my diploma thesis and was continued as open source project at DFKI, where I started working in 2004. In 2006, NEPOMUK started as a EU project (hence NEPOMUK was then used as project name for an EU research project, not for software) which funded research on Semantic Desktop. Gnowsis continued a bit until about December 2006, when we reached version 0.9.2, which is the last release.

Since then, most of our energy goes into dev.nepomuk.semanticdesktop.org ("Psew", nepomuk-server) which is a Java-based Semantic Desktop research prototype, and much work also goes into nepomuk.kde.org, which is a KDE based semantic desktop product.

nepomuk-KDE = product
gnowsis = Leo's hibernating Semantic Desktop open source project
nepomuk-server = java based semantic desktop research prototype (=most many features, but less inteagration with os as KDE has)
psew = GUI for nepomuk-server (at the moment also bundles nepomuk-server)

All of them share the same concepts: RDF on the desktop, a PersonalInformationModel, Annotation of everyday things, embedding into existing applications (=thats where we differ from others like haystack).

but as people keep asking about it: I do long for a working semantic desktop, and porting gnowsis' simplicity to KDE would indeed be nice.
How nice? Nice enough that you want to pay me something to do it?

Because I would like to continue working on this the next years (NEPOMUK EU project or not) .... the first six years were already quite rewarding :-)

Aperture 1.2.0 out

ANNOUNCEMENT OF Aperture 1.2.0 RELEASE

Aperture is a Java framework for extracting full-text content and
metadata from various information systems (e.g. file systems, web sites,
mail boxes) and the file formats (e.g. documents, images) occurring in
these systems.

Homepage:
http://aperture.sourceforge.net/

Download URL:
https://sourceforge.net/project/showfiles.php?group_id=150969&package_id=166878&release_id=636375

After three years of development Aperture is stable enough
to drop the .beta suffix from the release. 1.2.0 leverages
architectural improvements made in 1.1.0.beta to bring
support for compressed archives and to streamline
email processing. A completely new service - the
DataSourceDetector allows applications to provide
suggestions to users about the data sources on their
desktops. A host of bugfixes and minor improvements rounds
the image of the leanest and meanest version of Aperture
ever made. Enjoy.

What's new?
  • a completely new Aperture service - the
    DataSourceDetectors - can be used to provide advice to
    the user about the data sources on the desktop
  • new subcrawlers for .zip, .gzip, tar and bzip2 compressed
    files
  • unification of the email handling - now the ImapCrawler,
    MboxCrawler and the MimeSubCrawler use the same code in
    the DataObjectFactory to convert emails to RDF. The
    MimeExtractor has been deprecated, switch to
    MimeSubCrawler
  • some bugfixes in the email handling code, plain text, and
    xml attachments are treated correctly, threads are
    reflected in the resulting rdf
  • the pdf extractor has some basic support for XMP metadata
    (thanks to JempBox)
  • a completely new XmlSafetyUtil class that helps to deal
    with characters that are valid in RDF, but invalid in XML
    thus breaking the serialization
  • the uris of subcrawled resources follow the pattern
    established by the Apache Commons VFS project.
  • new Sesame 2.2.1 bundled with Aperture features dramatic
    performance optimizations, e.g. the aperture test suite
    is 2 times faster, this may also be a boost for your
    application
Best regards

Semantic-Web blogs about our Semantic Desktop talk

Jana Herwig from the Semantic-Web.at team blogged about Brian Davis and my talk at the webofdata.info practical semantic web workshop.

http://blog.semantic-web.at/2008/10/22/semantic-desktop-lifting-and-human-language-technology-wod-pd-session-2/

The next session at WOD-PD was given by Leo Sauermann (German Research Center for Artificial Intelligence DFKI, Germany), and Brian Davis (DERI Galway, Ireland). Leo introduced the idea of the Semantic Desktop, and more specifically, the Nepomuk Social Semantic Desktop.

thx!

Malaysia first web 3.0 country

This was just forwarded to me by Andreas Dengel:
"A Malaysian government applied research agency wants the country to be recognized as the first Web 3.0 society in the world.
MIMOS is driving the semantic technology industry in the nation towards this goal."

Read on at computerworld.ko.ke:

http://www.computerworld.co.ke/articles/2008/10/17/malaysia-aims-be-first-web-30-society-world

"Semantic technology is driving the next generation of the Web, the semantic Web, a machine-readable Web of intelligent data and automated services that amplify the Web far beyond its current capabilities," said Dato' Wahab, at the agency's Semantics Symposium in Malaysia.

Amazing find

This could be the Ferrari of metadata extraction tools. Helpful documentation and incredibly useful for building a search service on different document types. Easy to get started with, good range of features as well. Additional big boost to my list of yet another valuable tool. What a great find I have here.

A problem of semantic web: not providing XML value

Today in the morning, I had a sudden "insight" about one of the problems of RDF and Semantic Web: it misses some of the value that XML offers. This is what my daily commuting bike ride is for, thinking...

The adoption of Semantic Web rises and falls with the adoption of it in standardization bodies. For example the Oil&Gas industry of Norway is thinking about Semantic Web, and I have recently been talking with people from the automotive supplier industry about Semantic Web. To interchange data in a business-to-business environment you would expect that RDF has more features than XML, but in fact, it doesnt.
  • RDF is less expressive than XML. One example: you can't define pattern in RDF. Look in the XML spec, there is much more of it missing in RDF.
  • RDF is not validated. Although in theory, it is possible to validate a file for semantic correctness, nobody does that because of the open world assumption. Hence, there is no validation of the XML in mainstream applications.
So, if you are an industry, you already havean XML based standard, moving to RDF without the expressiveness of XML and without the notion of validation is tricky. RDF should have more features, not less.

Also the stack of XML technologies must be embraced better, for example a XSLT-friendly RDF/XML serialization. Please, dear reader, solve these problems and make a company around it.

Overloading Structure

I would argue that some of the complexity of XML (and XSD) is an attempt to overload what is essentially a standard for data structure to include components that represent data models.

When RDF is combined with RDFS and/or OWL, there is a greater ability to perform semantic validation while allowing for (what I see in my environment) the constant changes and additions to upstream data sources. While open world assumptions can make it difficult to detect data out of place, it can provide an easier framework for data models that are constantly changing (provided the downstream consumers have a plan in place for how they handle new data).

leobard - 24. Oct, 17:12

the argument is theoretic

The critique is: nobody validates RDF and there is no pressure nor tools to validate.

In theory... everything is possible, of course, but that does not help anyone buying a RDF validator or stopping people from writing
<http://www.example.com> rdf:type "muahahaha".

Springer's "Social Semantic Web" is out - kauf mich.

On Friday we received our author copies of Springers new masterpiece of Semantic Web books. Springer's "Social Semantic Web" - Web 2.0 - was nun"

Social Semantic Web Happy Authors

From left to right: M, Kinga Schumacher, Ansgar Bernardi, Leo Sauermann. We all were authors on the chapter on "Semantic Desktop", Malte additionally contributed to the chapter on Semantic Wikis. As you see we are very happy about our complimentary author's copy. Besides that - das buch ist gut.

Read it - in deutsch :-) . The authors (besides our small contribution) are the who-is-who of the German-speaking Semantic Web. Chris Bizer, Sören Auer, Sebastian Schaffert, Krötsch&Vrandecic, etc ...

edited by Andreas Blumauer and Tassilo Pellegrini, it brings together many authors from the practical side.
