Cette année, pour la deuxième fois, nous organisons l’atelier “Making Sense of Micropostes” qui vise à reunir des acteurs de recherche et de l’industrie travaillant avec les tweets, check-ins et d’autres contributions utilisateur à faible effort (microposts par la suite). Aujourd’hui, avec l’expansion et la maturité du Web 2.0 où les interactions des utilisateurs deviennent de plus en plus frequentes et de plus en plus abrégées, le traitement des microposts et l’extraction de sens à partir d’eux est importante plus que jamais. Nous aimerions notamment inviter les start-ups qui proposent des services dans ce domaine de soumettre des demonstrations de

The growing quantity of information that is coming to users from many different channels (twitter, Facebook, e-mail, etc.) and creates more and more an effect of saturation on the user’s attention. In such a situation it is reasonable to think that the user would be less and less likely to feel like in need for information and turn to Web search. It is thus more likely, that the user will prefer the information to fight for his attention than to explicitly perform the search.

If we try to look at the users and data from the supply/demand market perspective it

« Ouvre les yeux », dit un voix dans le film d’Alejandro Amenabar dont le titre reprend cette phrase. Ensuite, cette voix nous confronte à une révélation d’une réalité, autre que celle qu’on vient d’observer – une réalité à laquelle on ne s’attendait pas, mais qui a dû exister à notre insu et qui explique les ambiguïtés de la réalité perçue.

Quand on utilise le Web aujourd’hui, on se trouve assez souvent dans une situation pareille, où on a l’impression d’être bien informé, alors que les informations pertinentes peuvent nous échapper facilement. Au tout début du Web, dans les années

In earlier blog posts I talked about Semantic Proximity of concepts and using Linked Data to derive a notion of semantic relatedness. Driven by a more theoretic part of my thesis I was lead to consider other different ways to compute relatedness of concepts, such as those based on co-occurrence in texts, or those relying on the social graph. While we may speak of different performance of those approaches in different situations, there is nothing that would stop us from combining them. Obviously, if two different notions identify a pair of concepts as mutually related, then we can be more

I generally do not care much for music. Weirdly enough, I can imagine life without it and I am not touched by the majority of music I hear. There was however one (and so far only one) artist who managed to deeply touch me with her music – Amy Winehouse. Her voice, her songs, her attitude, her style – everything was so beyond everything else we can see that one can only stop, listen and admire.

She was a truly exceptional artist, and one of the rare people who could push the boundaries of what we know and make a

Research approaches for keywords suggestion have been around for quite some time. The need to help the users chose their keywords for tagging, web search and similar task lead to the development of a number of ways to suggest relevant keywords. Today, with the advent of web advertising, the finding relevant keywords has got a completely new dimension, as suggesting keywords no longer means just helping the user navigate on the Web, but also means driving the relevant visitors to your Web page. More and more services offer to suggest you the relevant keywords that cost less in advertising campaigns

Making Sense of Microposts: Big things come in small packages

Twitter, Facebook Like, Foursquare, and similar low-effort publishing services reduce significantly the effort required to participate on the Web. Enormous quantities of small user input are being piped into the data streams of the Web, leading to a rate of growth never before witnessed. We refer to such user input as “Microposts”; these can range from ‘check-in’ at a location on a geo-social networking site, through to a status update on

In one of my previous posts I talked about how value is created on the Web, and how users, by interacting with the services provided on the Web generate value (mostly through generating data and giving attention i.e. marketing space). Even more time ago, I wrote about why some social networks take off and other don’t (at least about some of the possible reasons of this).

However, a key to understanding of those phenomena related to user interaction with the Web and the success/failure of some Web services, is the understanding of motivations of users to use the Web and

A couple of weeks ago Tim Berness-Lee published a new article for Scientific American, called Long Live the Web. This provoked a number of reactions and interpretations that have been circulating around the Web. Most of them include that accusation that TimBL supposedly made about Facebook and how it is putting the Web in danger. Then, there are people saying that companies who rely on users’ online data to target them and make profit are also a danger to the Web. No matter how hard I tried I simply couldn’t find such claims in the text, and this

Last Friday I had the pleasure to present Semantic Web to a lively community of Parisian entrepreneurs, blogger, tech geeks and start-up people at Webdeux.Connect 2010. Presenting there was a revealing experience in two ways:

1. It made clear to me how far the start-up world actually is from the Semantic Web research, and how there are people totally unaware of its existence (not to mention potential).

2. How quickly, in talks with the start-up people, we come to concrete cases where Semantic Web can make a true difference.

I guess it means that we, the Semantic Web research

Quiet Tueseday morning is perfect from blogging – sun, absence of noise, fresh neewsfeeds and fruit – so here comes a blog with some recent thoughts. One of the most interesting things for me today is to follow how the “discovery” feature of the Web is growing in prominence. I recently discovered social networks that I didn’t even new existed, like Habbo and 4chan. I discovered Habbo on the recently published new version of Social Web map by Flowtown, by noticing a big area that I was totally unfamiliar with. Then I went to habbo and opened an

Many words have been written already about the data. Data is everywhere. Data is the next big thing. Data is the value on the World Wide Web. In this post I investigate how data contributes to the process of generating value on the Web, and how it is the crucial component of this process. The model that is presented here may not be too sophisticated, but it helps gain the basic understanding of why some services work, and others don’t. It is also an attempt to explain why some data exchanges are realistic, while others will probably never

Following became quite popular nowadays. It seems we are not so shy to follow any more. It is actually our following of people that makes them pop up, and shine in their relevance. Of course, I play here with multiple senses of the word “follow”. The video below explores the importance of following in the sense of being a follower of a spirit, of a state of mind, of an idea.

In this post however, I explore the following in the larger sense: following like watching, following development, life and evolution of something or someone. In short : following like

How many times have you faced another reality? I am talking about a feeling when you encounter a person, an event, a fact that has existed for ages in parallel with you, but you were totally unaware of it. It happens to me from time to time, to encounter someone who lives under totally different rules (different than my way of life, and different from all the people I am surrounded with), who has totally different values, who does totally different things, and who has a totally different perception of the world.

Although I am aware that I mostly live

Lindt Petits Desserts Musse au Chocolat Blanc is the chocolate of the month March. Although this is the kind of chocolate you can buy in a supermarket, Lindt provides an exceptional experience. This subtle, melting chocolate gives a sensation of a buttery late spring garden party, dipped in afternoon sun. It is a light experience, but still rich in cocoa butter flavors, with  contrasting textures  of mussy interior and glazed but easy melting exterior. Ideal for spring afternoons.

Chocolate of the month is the series of blog posts where I proclaim a chocolate of the month. While it is guaranteed

There has been a long time since I haven’t tasted a true Austrian cake; and when I was almost about to forget how great they were, Debbie brought me a Dobos Torte de Gerstner Konditorei (Vienna); with slight indications of rhum, a masterpiece of cake. If you ever come by Vienna, do not miss it

After a certain stage in their life-cycle, companies get so big that they turn into big closed worlds. I know such companies, where conditions of entry in the corporate buildings are more severe than on the borders between countries. You need to be announced and registered in the security system 15 days before, you must come with a passport, etc. The idea enhance with the outside world is of course a no-no in such worlds.

The apparent inefficiency of big companies has led to the development of many approaches in management that try to make the rigid corporate structures more
