Ontology is Overrated: Categories, Links, and Tags This piece is based on two talks I gave in the spring of 2005 -- one at the O'Reilly ETech conference in March, entitled "Ontology Is Overrated", and one at the IMCExpo in April entitled "Folksonomies & Tags: The rise of user-developed classification." The written version is a heavily edited concatenation of those two talks. Today I want to talk about categorization, and I want to convince you that a lot of what we think we know about categorization is wrong. In particular, I want to convince you that many of the ways we're attempting to apply categorization to the electronic world are actually a bad fit, because we've adopted habits of mind that are left over from earlier strategies. I also want to convince you that what we're seeing when we see the Web is actually a radical break with previous categorization strategies, rather than an extension of them.

Search v Enterprise Content Management Systems Written by Joe Tong on 29 March 2012 in Market Trends Photo credit: osuarchives/ A great debate has arisen (if you aren’t already aware) between those that believe in structure, taxonomies, ontologies and organization with those that believe that search technology is good enough for us to toss everything into one big bag and let the search engines sort it out. Elaine Svenonius and her book Intellectual Foundations of Information Organization (core reading for library science students) advise us to do the hard work of creating and maintaining organizing systems so that filing and retrieval is easy. Think of the difference between early Yahoo, and Google’s search engine breakthrough. So which approach do we take in our enterprise? What happens when we introduce the social layer into our enterprise systems? Keep reading Guident’s post “Which is more important: Search or ECM systems?”

La pratique du social bookmarking, les folksonomies et la gestion documentaire au service de l’enseignement de la traduction spécialisée 1 Étant donné, d’une part, que les termes originaux du domaine du social bookmarking sont anglo-amér (...) 1Les folksonomies, terme émanant du Web 2.0 et désignant l’indexation libre par l’apposition de mots-clés ou tags (étiquettes) à des articles, des photos, des sites, et tout autre contenu du web, offrent des possibilités indéniables à un groupe d’étudiants qui s’entraîne à la traduction spécialisée, au sein d’un établissement supérieur à dominante linguistique (LEA gestion-économie-commerce). Ces étudiants ne possèdent pas encore de connaissances suffisantes dans les domaines concernés pour avoir le réflexe de choisir, en langue-cible, le bon équivalent en termes de contenu conceptuel. 2 Thomas, S., Joseph, C., Laccetti, J. et al, 2007. « Transliteracy : crossing divides ».

Iowa gambling task The Iowa gambling task (hereinafter IGT) is a psychological task thought to simulate real-life decision making. It was introduced by Antoine Bechara, António Damásio, Hanna Damásio and Steven Anderson,[1] then researchers at the University of Iowa. It has been brought to popular attention by António Damásio (proponent of the Somatic markers hypothesis) in his best-selling book Descartes' Error.[2] The task was originally presented simply as the Gambling Task. Later, it has been referred to as the Iowa Gambling Task and, less frequently, as Bechara's Gambling Task.[3] The Iowa Gambling Task is widely used in research of cognition and emotion. Task structure[edit] Participants are presented with 4 virtual decks of cards on a computer screen. Screen shot of the Iowa Gambling Task Common findings[edit] Most healthy participants sample cards from each deck, and after about 40 or 50 selections are fairly good at sticking to the good decks.

Folksonomies: Tidying up Tags? 1. Introduction A folksonomy is a type of distributed classification system. It is usually created by a group of individuals, typically the resource users. Users add tags to online items, such as images, videos, bookmarks and text. In this article we look at what makes folksonomies work. 2. Probably the major flaw of current folksonomy systems – and the number one gripe for those happier with more formal classification systems – is that the tagging terms used in those systems are imprecise. Some users do not consider this a problem; they may argue that tags are there primarily to help the particular end-user who is submitting them. 3. So what exactly are tags? Two well-known examples of folksonomy systems, to which we will refer extensively in this article, are del.icio.us™ [3] and flickr™ [4], both services owned by Yahoo. In order to understand how we can make tags more searchable it is important to understand users and why they submit certain tags. Power laws and tag distribution 4.

m. john harrison interview - for zone-sf.com Light is being talked of (on the back cover, at least) as a 'return' to the genre: is that how you perceive it? Was Climbers a deliberate getting away from SF/fantasy and Light a deliberate return, or did things just work out that way? Climbers was a deliberate stepping away. Light isn't really a return: it's a very mainstream work. I don't think there should be anything that differentiates SF from the so-called mainstream, or the mainstream from SF. Depends, really, on what's going on down there in the less reachable parts of my skull! It's interesting that you pick up on sex as one structural element, which of course it is. I'm not a hard SF writer. The Chambers gun is one of a couple of lightweight references to The Centauri Device. Light was a fresh start. I liked anything bizarre, from being about four years old. I don't think we could ever have been called studious. I think we all felt a special connection to Cornelius in those days. Who knows?

Maintenir à jour l'index Solr d'un site Drupal | Whisky Echo Bravo Pour certains sites Web, il est essentiel que l'index de recherche soit mis à jour très fréquemment. C'est le cas de sites où la fréquence des ajouts ou modifications aux contenus est très grande; à la limite, avec une fréquence d'indexation trop basse, le système pourrait alors ne jamais venir à bout de la liste de contenus à indexer! Certains sites, par ailleurs, dépendent de requêtes de recherche pour alimenter directement une interface de navigation, rendant particulièrement désirable la présentation de données aussi actuelles que possibles. Nous avons été confrontés à ces enjeux récemment dans le projet d'une communauté en ligne. Le présent article décrit la manière dont nous avons résolu ce type de problème sur un site Drupal utilisant le module Apache Solr. Lancer le cron plus souvent Mais il y a un hic : L'exécution du script cron.php d'un site Drupal implique un grand nombre de tâches autres que l'indexation. Lancer le cron plus intelligemment Des alternatives Conclusion

Les folksonomies comme support émergent de navigation sociale et de structuration de l'information sur le web Multiplicité des politiques de structuration du web Depuis sa création au début des années 1990, le web a connu des évolutions importantes aussi bien sur un plan technique que sur celui des usages. Aujourd’hui, on recense plusieurs dizaines de milliards de pages web, pour plus de cent millions de sites web « indexables » à travers le monde, contre seulement 100 000 en 1996, soit six ans après sa création [5] hhttp :// www. worldwidewebsize. com/ – http ://fr.wikipedia.... [5] . Le web peut être décrit comme un espace documentaire dont l’organisation est anarchique et en évolution permanente. La structuration des données du web et leur accessibilité par des agents humains et non humains représentent donc des enjeux centraux de son développement dans les prochaines années.

Elysium Revisited Noisy Jelly Raphaël Pluvinage et Marianne Cauvard ont eu l’excellente idée pour un projet à L’Ensci de créer cette « Noisy Jelly ». Le but de ce projet est de proposer de cuisiner et façonner son propre matériel musical avec de la gelée. Une idée à découvrir en vidéo dans la suite. » The “Decoy” Pricing Model Alex Mandossian’s Blog According to Wikipedia, the “decoy effect” (also known as the ”asymmetric dominance effect”) is the phenomenon whereby consumers change their preference between two options when also presented with a third option that is asymmetrically dominated.” In plainer language, here’s the way decoys are utilized daily during consumer experiences. Scenario 1: You order a medium-size Pepsi at the movies for $2.75 and the person behind the counter asks, “Would you like a large for just 25 cents more?” You say, “Yes”… that’s the decoy effect.Scenario 2: You’re sitting at the bar in an airport terminal waiting for your plane to board. As soon as you order your $7 cocktail, the bartender smiles and says, “Want a double-shot for just $2 more?” I have no idea what your consumer response would be in similar circumstances, but I do know from my own experience that I will choose the asymmetrically dominated option nearly 100% of the time! Good question. Offer A: Internet-only subscription for $59 Not exactly…
