Next week I’ll be attending at ISWC2008, The 7th International Semantic Web Conference, in Germany. I’ll go with some colleagues from Globo.com: Marcio Tristão, Leandro Gejfinbein and Fernando Carolo.

I’ll try to give some reports during the event. Maybe this blog come back to live, who knows…

ESPN Brasil lauched it new website last week. Only today I took notice of that, reading Silvia Melo’s post about it.

Despite the new audacious interface design (I’m not pretty sure about it’s efficiency), the central question is that it lacks the basic: content. After the first impression, when you start to use it, there’s no new offer. Taking Google as a benchmark for user navigation behavior seems to me a little misconception. A so hidden navigation menu is a rupture that I’m not sure people are ready to face.

The new ESPN Brasil Homepage. Audacious interface design, but is it efficient?

An internal page, built upon searching a pre-configured tag. Impressive, but lacks rich related content

The only thing that seemed to me an interesting feature is the related content ‘mind mapped’ at the end of the page, with the related tags represented with photos. That’s a cool navigation system I would like to study more deeply to check it efficiency. Choosing Tags as a central navigation system without a semantic tool or controlled vocabulary to support it is quite a risk. Specially when you have a very poor relation between the items (volley has only three related terms).

And there are some implementation problems. As you try to break the tag search, you may reach a page that has no picture to illustrate it, and you get the content left miles away from the top of the page.

A fragile URL building rule system makes the page miss the opening background image

At the end, the new ESPN Brasil website intends to use a (somehow) new user interface design, but fails on offering clear navigational paths. Using search is not as fluid as pointing and clicking, and putting all the bets on related tags doesn’t guarantee a flow. Nice work, good experiment, but still with lot to be improved.

As I wrote before, I’m at the Semantic Technology Conference or SemTech2008 to simplify. The first day was only to align concepts and put everyone up to date of where we are.

Dave McComb, from Semantic Arts opened with a presentation basically highlighting the basic concepts that would be discussed along the event. Some are pretty old, like False positives and False negatives on search results, but the approach was obviously how semantic apps could help improving these questions. The shift from the web as we know is inevitable, due to the great amount of unstructured data is generating noise and it’s getting hard to work with the relational data model. Data must shift to Information, as information means knowledge. And some of the most recent efforts are on the Entity Extraction, with lots of tools for finding and associating entities found in text with concepts on ontologies. At the end, these information would allow the systems to make inferences and discoveries that wasn’t initially declared.

Ivan Herman, specialist from W3C on semantic web, made a broad presentation of what they’re focusing at the W3C, which are the discussions that are burning at the community and talked about some technologies that they are putting their bets on. As far as I saw, Dublin Core and FOAF are a common sense at the vocabulary level, as they appeared as good examples in both presentations and in every book about semantic. SPARQL is the Query Language that with RDF and WOL OWL seems to be under the spotlight now.

Ivan talked a little about an interesting project called the ‘Linking Open Data Project’, which Goal is to ‘expose open databases in RDF’, setting RDF links among data items from different databases and setting up SPARQL endpoints to query the data. The first practical project One of the projects of this initiative is the DBPedia: by extracting data from that “infobox” on wikipedia pages (right columm) from a City, for example, and integrating with the city information on the US Census database they can build a stronger an richer knowledge of that city.

At this elaboration stage there are still lots of issues, but these were the ones Ivan talked about: security, trust, provenance; ontology merging, alignment, term equivalences; Uncertainty. The most important for me were the ontology merging and uncertainty. The web as we know was build on sharing and linking documents. Now, on the Semantic wave the same concept must be applied. There’s no need to build a complete new ontology on geonames, for example. Just link to an existing and build one just for your own knowledge domain. I firmly agree with this vision.

But was we already know, documents published on the web are hard to control, and there’s no guarantee that they’ll be there forever. A 404 result for a document search is no big deal, but when it comes to build an application based on an external ontology maintained for a third part that you have no relation, there’s a huge difference. That was an issue that I personally asked Ivan, and he said everybody is asking the same question, that’s a big problem that the W3C itself is worried about, but unfortunately there’s no light at the end of the tunnel yet.

Who’s gonna take care of the integrity of all these dependencies?

Ivan’s presentation for the SemTech2008 is available for download at the W3C website.

updated: Daniela Barbosa shared on her delicious some links from this first day.

Just a quick note… tomorrow I’ll fly to San Jose, California, to take part (as an atendee) of the SEMTECH - Semantic-Technology Conference 2008. I’ll see if I can post some notes about what I’ll see, but can’t guarantee that.
