LTU Engine Aids Searches for Stolen Art

This fascinating article was written by LTU technologies and appears here on their website.

More than 11 billion dollars is the estimated value of the art pieces stolen throughout the world every year – and this does not take into account the looting of archeological sites. In Europe, more than 60 thousand art objects are stolen each year.

Artistic heritages are priceless – to nations and to families. The criminal activity associated with these thefts, on a worldwide basis, ranks second only to traffic in illegal drugs.  Traffic in stolen art, previously limited to specialized criminals, is increasingly associated with more general criminal activity since stolen art can be used in schemes for money laundering.

Also, modern communication methods like Internet and more rapid and easier international commerce have opened new opportunities for this kind of traffic.

On this last point, it is interesting to note that, concerning thefts from private individuals, a certain number of objects that were stolen years or even decades ago are now re-appearing, either at official sales or in transactions between individuals via Internet.  Indeed, after several sales cycles, it is very difficult to establish that an object is, in fact, stolen property.  Very often the sellers believe that they are indeed the rightful owners of the objects.

The importance of images in stolen art investigations.

The image or, more generally, the visual aspect of an art object is always its prime identity.  First, because it is inherent in the art object and because, in most cases,  what the object looks like is the primary vector for identifying the work.

From this it follows that information exchanges or other communications about an art object always rely on at least one visual representation of the object
-    Printed information on the art works or, more generally , art history.
-    Media
-    Gallery and auction catalogues (printed or on the Internet)
-    Internet sites for sales between individuals
-    Etc…

Further, the popularization of digital imaging is today a reality and has led to a proliferation of visual content that is accessible to every one, whatever their professional or amateur status.

While a number of technologies have addressed the challenge of retrieving textual information (data mining), it is not the case with images.

An effective and powerful solution for investigating images, LTU engine has become the accepted standard for both private and governmental organizations.

This complete software solution permits matching and associating images by their visual content, which allows the simple and effective investigation and identification of photographed objects.

Omgili Health and iMedix – synergy in action

Consumer health search is hot (think Organized Wisdom). Online patient communities are sprouting everywhere (Trusera, MedHelp, Healia). A theme we heard sounded repeatedly by top execs of such firms at the Health 2.0 conference was that consumers want easy, immediate access to commentary from other consumers within the framework of reputable consumer health sites.

Here is a case study. Today we will look at the partnership between Omgili and iMedix.

Now, you are going to have to be patient with me on this one because this review is going rely on a lot of copying and pasting from the Web sites and marketing info of the firms under discussion. But that is often the best way to explicate matters. As noted above, I attended the Health 2.0 conference—the theme of which was, “User-Generated Healthcare.” In the case of Omgili Health (a sub-section of Omgili) and iMedix, which has been written up very interestingly here: we are talking, “User-Generated Healthcare Content.”

And Omgili has the expertise and the reach to capture a lot of that (and there is a lot of it out there) and render it findable.

Now, I work in a medical library and many information professionals pooh-pooh the chitchat of disease and consumer health message boards and justifiably worry about the quality of information (which ranges from homespun commonsense to innocuous quackery to the downright dangerous and fraudulent) that can be conveyed in such venues. But I have spent many hours on the amyotrophic lateral sclerosis pages of the online patient community Patients Like Me and came away convinced that when such sites are overseen in a responsible manner they are invaluable sources of practical information and mutual support and comfort to those in distress and in need of help that often they are not able to get (or at least expeditiously) from the medical establishment for reasons of income or geography.

Here is where Omgili’s strength is in this sphere. It makes it clear that this is not the world of peer-reviewed meta-analysis-laden land of PubMed. Rather, in the words of Omgili, “Omgili is your way to find “subjective information”. As opposed to traditional search engines, which search for sites and pages, Omgili finds consumer opinions, debates, discussions, personal experiences, answers and solutions. Most of the questions have already been answered – find the answers through Omgili. Most of the technical problems have been solved – find the solutions through Omgili. Most of the experiences have already been described -find these descriptions through Omgili. Omgili is a crawler based, vertical search engine that scans millions of online discussions worldwide in over 100,000 boards, forums and other discussion based resources.”

Now that is a very valuable service and is something that is not being done effectively in the health care search space to my knowledge.

For instance, I spend many hours a day trawling the Web looking for grants for health care researchers. As I do so, I visit site upon site related to disease and medical science. Many disease-related sites are aimed at tiny audiences (e.g., those interested in research in very rare chromosomal disorders). But these sites often feature fascinating discussions or commentary on issues related to disease and disability, legislation and advocacy issues, medical devices and innovations in such fields and practical advice for dealing with all the awful complexities of insurance that the chronically or suddenly ill must confront. Kudos to Omgili Health for making it possible for those suddenly faced not only with life-threatening illness but financial hardship to save time and find social support in key decisions in various stages of their illnesses. This is health search at its finest and an example what the Web can be in its best moments. Yes, much of the info one might find would be fluff for the worried well and of the superficial variety. But in these days of unemployment and strained family budgets, helping users find simple home remedies or sound advice from helpful laymen is a public service and could save some lives—it could be the case that a consumer using Omgili Health might be urged by a concerned fellow user to get to a doctor.

As to iMedix, I was quite impressed by the handsomeness of the site and the range of videos available and found it quite touching that someone had gone to the trouble of creating a simple but extremely useful video on, Use of cough assist for clearing lungs of ALS person using a ventilator:

I had only read about that technique and it was an immense help to see the devoted layperson caregiver and the generous ALS patient demonstrating its use for the benefit of others they may never know they have so helped. Devices like that can be frightening for those facing them as patients and as caregivers and videos like this courtesy of iMedix hugely allay anxiety and make the once scary into something manageable and even reassuringly routine.

We are all so lucky to be living in an era where even the most devastating illnesses can be coped with better thanks to such sites. Knowledge truly is power and more and more of knowledge is getting out onto the Internet.

For instance, the other day at work I wrote up for a health educator an introduction to online patient communities and also mentioned discussion boards and to do so had to bop over to many sites and create a long list of links. Talk about time-consuming and scattershot search methodologies. Omgili Health will make tasks like that easier for those of us in medical settings and in public health and certainly for consumers. Let us hope it will also be able to similarly aggregate material from the growing number of wikis on health topics. Nobody seems to be doing that and that may be hard technologically, given that many wikis lie behind corporate or organizational firewalls. But Omgili Health has made a good start at similar tasks and iMedix is raising the bar for the use in consumer health search of the bells and whistles of Web 2.0. And there is lot to be said for bells and whistles—as I write these words I am listening to this useful backgrounder on ALS: What’s Up Wit’ That? ALS Association:

This is a useful, edifying discussion that I had not encountered before elsewhere that —and that is the mark of a good health site.

Omgili Health and iMedix—synergy in action for the benefit of all those interested in good quality consumer health info in many formats and media.

Deepdyve: le moteur pour explorer le web invisible?

Posted in Guest Authors, Reviews | No Comments »


Deepdyve fait parti de ces moteurs de recherche qui considère que les recherches menées sur les moteurs classiques (Google, Yahoo…) ne renvoient pas de résultats suffisamment appropriés, laissant ainsi certains contenus à l’abandon alors qu’ils sont très qualifiés. Deepdyve a été conçu via un langage indépendant ayant pour but d’exploiter du mieux possible les contenus trouvables sur le web. Sur le papier, ça sonne bien, mais voyons un peu ce que l’outil a dans le ventre…

Après une inscription rapide à la version bêta, on accède à une interface élégante et simple à utiliser. Un grand champ texte est disponible pour effectuer sa recherche et si la plupart des moteurs fonctionnent mieux avec une requête composée de 2 ou 3 mots, Deepdyve vous invite à exprimer clairement et précisément votre besoin, si besoin en utilisant une phrase. En dessous, on trouve des informations réparties sur 3 colonnes : l’historique de vos recherche, les résultats de recherches sauvegardés et enfin une colonne avec quelques exemples.
