Pierre Levy vs Tim Berners-Lee, round 0.1

Wednesday, May 14th, 2008 (viewed 331 times since 17 April 2006)

Yesterday, I attended a research seminar at the “Université de Paris 8″. Pierre Levy is a philosopher and professor and head of the collective intelligence chair at the University of Ottawa, Canada. He presented the latest developments in his work on IEML, which stands for Information Economy Meta Language. Things are taking shape on this […]

Web scraping, web mashing

5 Ways to Mix, Rip, and Mash Your Data introduces promising web and desktop applications that extract structured data feeds from web sites and mix them together into something possibly useful to you. Think of things like getting filtered Monster job ads as a convenient RSS feed, along with job ads from your other favorite […]

WikiCalc: Web 2.0 spreadsheets wikified

Wednesday, July 26th, 2006 (viewed 3156 times since 17 April 2006)

WikiCalc is a nice piece of GPLed software that pusblishes wiki pages that are structured like Excel spreadsheets are: one can view and edit tables, modify calculation formulas in cells, manage their formatting through the web browser, etc. It brings to spreadsheets the inherent advantages of many wikis: ease of use for Web publications, ease […]

Critiques du web sémantique

Tuesday, September 6th, 2005 (viewed 2327 times since 17 April 2006)

Le Web Sémantique est l’objet de nombreuses critiques. On reproche principalement à cette vision technologiste son manque de pragmatisme. Voici les références de deux articles illustrateurs de ces critiques.
Clay Shirky soutient que la gestion d’ontologies n’est pas une sinécure et que les technologies de “social tagging”/”folksonomies” sont une alternative beaucoup plus adaptée à l’Internet que […]

From flat text to structured data

Monday, September 5th, 2005 (viewed 1763 times since 17 April 2006)

This article shows an example of how to build structured data sets from flat text. The example given is the detection of existing relationships between (ex-)members of the British government by data-mining the wikipedia. This relates to “bubble-up folksonomies”. These folks at the BBC are smart !

Semantic Web reports for corporate social responsability

Thursday, May 26th, 2005 (viewed 2335 times since 17 April 2006)

With that amount of buzzwords in the title, I must be ringing some warning bells in your minds. You would be right to get cautious with what I am going to say here because this is pure speculation. I would like to imagine how annual (quarterly ?) corporate reports should look like in some near […]

From OWL to Plone

Thursday, April 28th, 2005 (viewed 2563 times since 17 April 2006)

I found a working path to transform an OWL ontology into a working Plone content-type. Here is my recipe :

Choose any existing OWL ontology
With Protege equipped with its OWL plugin, create a new project from your OWL file.

Still within Protege, with the help of its UML plugin, convert your OWL-Protege project into a UML classes […]

Web scraping with Python (part II)

Friday, March 11th, 2005 (viewed 21098 times since 17 April 2006)

The first part of this article dealt with retrieving HTML pages from the web with the help of a mechanize-propelled web crawler. Now your HTML pieces are safely saved locally on your hard drive and you want to extract structured data from them. This is part 2, HTML parsing with Python. For this task, I […]

P2P + Web Sémantique + Réseaux sociaux + Bureautique = ?

Wednesday, March 9th, 2005 (viewed 1030 times since 17 April 2006)

Prenez une once de peer-to-peer, trois coudées de web sémantique, deux livres de bureautique et un denier de réseau sociaux, malaxez avec énergie et vous obtenez… le “Networked Semantic Desktop”. Ca c’est de la convergence où je ne m’y connais pas… Projet de recherche, circulez, il n’y a rien à télécharger ! Vu également ici.

Jointure d’identité et réseaux sociaux

Wednesday, March 9th, 2005 (viewed 1192 times since 17 April 2006)

IBM a récemment acquis SRD, éditeur d’un logiciel qui met en correspondance :

diverses descriptions informatiques d’un même individu (jointure avancée d’identités),
les relations établies entre individus d’après leurs points communs (établissements de réseaux sociaux)

Bref, un logiciel tout à fait adéquat pour qui veut se constituer la parfaite panoplie du petit big brother.
Cette technologie semble un peu […]

Zemantic: a Zope Semantic Web Catalog

Monday, February 14th, 2005 (viewed 1291 times since 17 April 2006)

Zemantic is an RDF module for Zope (read its announcement). From what I read (not tested by me yet), it implements services similar to zope catalogs and enables universal management of references (such as the Archetypes reference engine but in a more sustainable way). It is based on RDFLib, similarly to ROPE.
I feel enthusiastic about […]

Web scraping with python (part 1 : crawling)

Wednesday, December 29th, 2004 (viewed 27659 times since 17 April 2006)

Example One : I am looking for my next job. So I subscribe to many job sites in order to receive notifications by email of new job ads (example = Monster…). But I’d rather check these in my RSS aggregator instead of my mailbox. Or in some sort of aggregating Web platform. Thus, I would […]

RDF vu par un pouet

Thursday, December 9th, 2004 (viewed 1294 times since 17 April 2006)

La technologie RDF est la brique de base du web sémantique. Dans une grange, un poète vous rappelle qu’à l’école maternelle, vous saviez déjà faire du RDF avec des ours funambules.

La vision de chez Mac Donald Bradley au sujet du web sémantique

Friday, September 17th, 2004 (viewed 989 times since 17 April 2006)

J’ai été très impressionné par la qualité de la vision du directeur scientifique de chez Mc Donald Bradley au sujet du web sémantique. Il présente non seulement de très justes illustrations de la vision de Tim Berner’s Lee mais il la remet également de manière très pertinente dans le contexte général de l’évolution de l’informatique […]

Plone as a semantic aggregator

Thursday, August 12th, 2004 (viewed 7789 times since 17 April 2006)

Here is an output of my imagination (no code, sorry, just a speech) : what if a CMS such as Plone could be turned into a universal content aggregator. It would become able to retrieve any properly packaged content/data from the Web and import it so that it can be reused, enhanced, and processed with […]

Is the Semantic Web stratospheric enough ?

Friday, August 6th, 2004 (viewed 1159 times since 17 April 2006)

Did you think the Semantic Web is a stratospheric concept for people smoking too many HTTP connections ? If so, don’t even try to understand what Pierre Levy is intending to do. He and the associatied network of people say they are preparing the next step after the Semantic Web. Well… In fact, I even […]

RSS : The Next Big Thing Online

Voici un papier blanc (si, si…) au sujet de RSS (à nouveau via l’excellent Outils Froids). Enfin un document qui présente l’écosystème RSS en des termes marketing compréhensible par une D.S.I. de grande entreprise… enfin j’espère. Je testerai ce document sur mes collègues et supérieurs à mon retour de congés.

Reinout’s ROPE

Monday, April 26th, 2004 (viewed 1796 times since 17 April 2006)

Good news ahead : Reinout van Rees has recentrly restarted struggling with his ROPE project. I had just been thinking about the current status of this project this weekend. I hope there will soon be some nice RDF support within Zope. And ROPE is made for this since ROPE = Rdflib + zOPE.
