Microsoft Word - HT06 Cameron 060611.doc - Hypertext2006.pdf - 0 views

  • Despite these individual contributions (which we will revisit in more detail in Section 2), to fully understand tagging systems we believe a holistic approach is necessary. Walker [24] describes tagging as “feral hypertext”, a structure out of control, where the same tag is assigned to different resources with different semantic senses, and thus associates otherwise unrelated resources. However, by considering the entire model, computer systems could make inferences that “domesticate” (to use Walker’s terms) these “feral” tags. For example, tag semantics and synonyms could potentially be inferred by analyzing the structure of the social network, and identifying certain portions of the network that use certain tags for the same resource, or related resources, interchangeably. These tags may be synonymous
  • Different designs and user incentives can have a major influence on the usefulness of information for various purposes and applications, and in a reciprocal fashion, on how users appropriate and utilize these systems. The design of the system may solicit tagging useful for discovery, retrieval, remembrance, social interaction, or possibly, all of the above
  • Other likely explanations for the observed correlation between social connection and common tag usage may be found in the descriptive categories of sociolinguistics which studies how different geographic and social formations structure the coherence and diffusion of semantic and syntactic structures in various ”lects” within a larger sociolinguistic system. Some of these example lects include: dialect (a lect used by a geographicallydefined community); sociolect (a lect used by a socially defined community); ethnolect (a lect spoken by a particular ethnic group); ecolect (a lect spoken within a household or family); and idiolect (a lect particular to a certain person). If we conceptualize social tagging systems within the theoretical frame of sociolinguistics, these and other “lects” seem especially applicable to understanding and classifying the apparent isomorphism between social and linguistic structures we observed in Flickr. The structures, changes, and diffusion within and amongst various “lects” in social tagging systems will likely have similar patterns to those found in social network analyses and in sociolinguistic language maps.

Shirky: Ontology is Overrated -- Categories, Links, and Tags - 1 views

  • 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.

  • Yahoo is saying "We understand better than you how the world is organized, because we are trained professionals. So if you mistakenly think that Books and Literature are entertainment, we'll put a little flag up so we can set you right, but to see those links, you have to 'go' to where they 'are'."
  • You don't have to have just a few links, you could have a whole lot of links.
  • A URL can only appear in three places. That's the Yahoo rule.
  • They missed the end of this progression, which is that, if you've got enough links, you don't need the hierarchy anymore. There is no shelf. There is no file system. The links alone are enough.
  • One reason Google was adopted so quickly when it came along is that Google understood there is no shelf, and that there is no file system. Google can decide what goes with what after hearing from the user, rather than trying to predict in advance what it is you need to know.
    • Caro Mailloux
       
      Laisser les usagers se faire leur langage et le tagger à leur façon puis, en tant que Google, prendre cette info et l'utiliser pour créer une ''taxonomie''.
  • "Well, that's going to be a useful category, we should encode that in advance."
  • They point to the signal loss from the fact that users, although they use these three different labels, are talking about the same thing.
  • You can also turn that list around. You can say "Here are some characteristics where ontological classification doesn't work well": Domain Large corpus No formal categories Unstable entities Unrestricted entities No clear edges Participants Uncoordinated users Amateur users Naive catalogers No Authority
  • The other big problem is that predicting the future turns out to be hard, and yet any classification system meant to be stable over time puts the categorizer in the position of fortune teller.

  • Here is del.icio.us, Joshua Shachter's social bookmarking service. It's for people who are keeping track of their URLs for themselves, but who are willing to share globally a view of what they're doing, creating an aggregate view of all users' bookmarks, as well as a personal view for each user.
    • Caro Mailloux
       
      chouette description concrète de l'utilisation de del.icio.us!
  • " If you find a way to make it valuable to individuals to tag their stuff, you'll generate a lot more data about any given object than if you pay a professional to tag it once and only once.
    • Caro Mailloux
       
      utilité du tagging
  • Tags are simply labels for URLs, selected to help the user in later retrieval of those URLs. Tags have the additional effect of grouping related URLs together. There is no fixed set of categories or officially approved choices. You can use words, acronyms, numbers, whatever makes sense to you, without regard for anyone else's needs, interests, or requirements.
    • Caro Mailloux
       
      Chouette description de ''Tags''.
  • The chart shows a great variability in tagging strategies among the various users.
  • But this is what organization looks like when you turn it over to the users -- many different strategies, each of which works in its own context, but which can also be merged.
  • We are moving away from binary categorization -- books either are or are not entertainment
  • But they either had no way of reflecting that debate or they decided not to expose it to the users. What instead happened was it became an all-or-nothing categorization, "This is entertainment, this is not entertainment." We're moving away from that sort of absolute declaration, and towards being able to roll up this kind of value by observing how people handle it in practice.
  • What you do instead is you try to find ways that the individual sense-making can roll up to something which is of value in aggregate, but you do it without an ontological goal.
  • you believe that we make sense of the world, if we are, from a bunch of different points of view, applying some kind of sense to the world
    • Caro Mailloux
       
      ''we make sens of the world together thru what's worth aggregating'' = not ontology 
  • we're going to be able to build alternate organizational systems, systems that, like the Web itself, do a better job of letting individuals create value for one another, often without realizing it.
  • If you think the movies and cinema people were going to have a fight, wait til you get the queer politics and homosexual agenda people in the same room.

Folksonomies et communautés de partage de signets Vers de nouvelles st... - 1 views

  • Les folksonomies peuvent constituer une alternative aux moteurs de recherche en permettant la construction de parcours et la mise en réseau d'informations mais aussi de personnes.
  • Pour beaucoup d’usagers, la recherche d’information est devenue synonyme de moteur de recherche voire de  « googlisation ». Cependant il existe désormais des alternatives à ce quasi monopole via notamment les folksonomies, mot composé par Thomas Vander Wal à partir de folk et de taxonomy et qui définit la possibilité offerte à l’usager d’ajouter des mots-clés à des ressources. Leurs stratégies de recherche diffèrent de la traditionnelle médiation des moteurs. Nous nous sommes interrogés sur la pertinence des folksonomies et leur intérêt réel dans le cas de la recherche d’information. En effet, la démarche « folksonomique » diffère de la simple requête et suppose d’autres habiletés. Cette analyse s’inscrit dans nos recherches sur les habiletés informationnelles ( information literacy ) Nos travaux sur ces nouveaux modes de partage et recherche d’informations s’appuient sur de nombreux tests des différentes plateformes permettant l’intégration de mots-clés qualifiés de tags. Nous nous sommes tout particulièrement ici appuyés sur les systèmes de partages de signets parfois appelés « marque-pages sociaux », voire signets sociaux (social bookmarks). Nous avons pu d’ailleurs constater que les différents sites d’intégration de favoris ont veillé à l’interopérabilité de leur système le plus souvent en utilisant le format xml. Une possibilité qui n’était pas offerte sur tous les sites il y a encore un an
  • Faut-il pour autant voir dans ces systèmes un concurrent  potentiel des moteurs ? Nous songeons plutôt à les considérer comme des alternatives au sens de cheminements de recherche différents qui nécessitent une construction et non une logique de push
  • ...10 more annotations...
  • Les moteurs de recherche manquent souvent de pertinence du fait qu’ils reposent sur un tri effectué par un robot. Les folksonomies reposent quant à elles sur une médiation humaine, il est vrai imparfaite.
  • Il est possible d’identifier des « folksonomistes » que l’usager perçoit comme référence ce qui permet facilement ainsi de réaliser de la veille collaborative.
  •  " Combien vous vous trompez, mortels, en voyant dans ce trompeur édifice une tromperie qui veut vous égarer (…) Même si les chemins sont parfois parsemés d’embûches et semblent constituer de mauvaises directions, les folksonomies sont plus fidèles au cheminement hypertextuel. Cependant elles nécessitent un apprentissage voire une tag literacy
  • Les communautés virtuelles pour ne pas les nommer « collèges invisibles » devenant ainsi le socle des folskonomies
  • Trailfire[8]qui permet à l’usager de créer des parcours de sites web avec annotations inclues sur la page. Chaque parcours recevant un tag. Les possibilités pédagogiques sont ici assez évidentes puisque cette technologie permet l’insertion de billets explicatifs ou de commentaires à n’importe quel endroit de la page.
  • Les folksonomies sont parfois critiquées du fait que tous les folksonomistes ne sont pas tous des « gentlemen »
  • la participation à des groupes thématiques de veille ou tout au moins à une volonté de mettre ses découvertes à disposition des autres.

    Technology can augment the discovery and creation of knowledge. For instance, some drug discovery approaches embody a system for learning from models and data that are extracted from published papers and associated datasets. By assembling large databases of known entities relevant to human biology, researchers can run computations that generate and test hypotheses about possible new therapeutic agents
