Search Yottalook in 33 Languages!

Today, we launched our beta version of Yottalook Worldwide, which will allow users to search in one of 33 different languages. People from over 160 countries have used Yottalook to date, and we wanted to improve user experience for whom English may not be their first language.

We are using Google Language API to provide translations of search term queries. When you type in a search term in one of 33 different languages supported, Google Language API translates the search string into English. This then gets sent to our Yottalook Images or Journals engine and the results are shown. Once translated, the search terms undergo same query expansion as Yottalook in English.

Following languages are supported:
  • Arabic
  • Bulgarian
  • Chinese (Simplified and Traditional)
  • Catalan
  • Croatian
  • Czech
  • Danish
  • Dutch
  • English
  • Finnish
  • French
  • German
  • Greek
  • Hebrew
  • Hindi
  • Indonesian
  • Italian
  • Japanese
  • Korean
  • Latvian
  • Lithuanian
  • Norwegian
  • Polish
  • Portuguese
  • Romanian
  • Russian
  • Spanish
  • Serbian
  • Slovak
  • Slovenian
  • Swedish
  • Ukrainian
  • Vietnamese
You can type your search term in one of the 33 supported languages in the search box then select your language from the drop-down menu. Once you click on search, your query term(s) will be translated into English and search results will be shown. Your language preference will be saved for each online session. Once in the results page, you can search either in the language you selected previously or in English as the search box will understand both. For Spanish, French and Portuguese, we have implemented additional features. Look for the button; when you mouse over it, you will see translations of the caption appear (please give it a second or so to perform the translation; we are aware that the popup box with translation sometimes does not disappear, if you let it complete its translation process prior to moving your mouse that help preventing this. However, we are looking into having a better solution for this issue).

Same Yottalook Terms of Use and Disclaimer apply. Please note that this is currently in BETA. We are aware of limitations of the Google Language API and are looking for more ways to improve this engine. For example, that is why the button option has been only turned on for 3 languages so far. I have personally tested out Korean and found this feature to be not very helpful. If you are interested in testing out different languages, please contact us as we can generate special links that will allow you to test this feature.

Please help us improve this engine by providing us with your feedback. Despite limitations, we hope many of you will find this new interface useful.

New Images from Imaging Consult

We have just indexed more images to our search engine in anticipation of RSNA. Yottalook Images will now also show results from Elsevier's Imaging Consult. We are currently working to increase our index even more. Stay tuned for more updates.

Yottalook Integrated Within GE Centricity PACS-IW

GE and Yottalook have created a working prototype integration between GE's Centricity PACS-IW and Yottalook. Go to GE Healthcare IT (Booth #5529) at RSNA to check it out.

Yottalook's New Updated Images Engine

We have updated our Images engine to include more images.

If you look at the middle of the screen where we have our filters, you will find a brand new filter option called "No Subscription Mode: ON OFF". We have received many feedback requesting ability to filter out images where users don't have subscriptions to. We understand, that while many users from large academic centers may have access to many journals online, this is not the case for many of our users. By turning this option, Yottalook Images will attemp to maximize results that do not require subscription for viewing and bring those results near the top.

Our update includes more than increased number of images. We have also enabled media RSS capability. Download Cooliris, and click on "Start Slide Show" next to the bookmark button below the search box. Experience the new "3D Wall" that lets you browse through hundreds of images with ease and speed. Click on the image to view a larger version as well as caption.

Yottalook at RSNA 2008

Want to find out more about Yottalook? During RSNA this year, we will be having following sessions/presentations and exhibits.

Yottalook Local™: Demonstration of an Enterprise-wide Semantic Search Engine for Patient Information

This exhibit demonstrates the use and applications of an enterprise-wide semantic search engine to index radiology reports. The Yottalook Local search engine allows radiologists to search for patient information and reports quickly. By analyzing user queries in real time, the engine further enhances the user search experience by providing thumbnails, related terms using various ontologies, query-related special content, and modification of search results based on specific query terms used.

Sun (Nov 30) 8:00 AM - 6:00 PM
Mon (Dec 1) - Thurs (Dec 4) 7:00 AM - 10:00 PM
Fri (Dec 5) 7:00 AM - 12:45 PM
LOCATION: Lakeside Learning Center

Multimedia RSS for Immersive Display of Radiology Image Search Results

Multimedia RSS (MRSS) can be used to display radiology image search results from the web in a highly optimized and immersive 3D environment which permits the user to zoom, pan, and "fly-though" their search results. We will discuss similarities and difference between standard MRSS and RSS and how to use various online and client RSS readers to subscribe to MRSS feeds. We will also demonstrate how to use MRSS to distribute other multimedia content including radiology resident conference video.

Sun (Nov 30) 8:00 AM - 6:00 PM
Mon (Dec 1) - Thurs (Dec 4) 7:00 AM - 10:00 PM
Fri (Dec 5) 7:00 AM - 12:45 PM
LOCATION: Lakeside Learning Center

SESSION: What are Radiologists Searching For? - Obtaining Quality Information at the Desktop, Radiology Specific Search Engines and Beyond
Finding the right information at the time of patient care: Yottalook case study

The web search engine has become the preferred decision support tool by Radiologists, however, overall satisfaction levels for websearch remain relatively low. Multiple factors contribute to this dissatisfaction including: (1) content returned by a search often does not adequately address the question being asked, (2) the content is not presented in a way that it can be "digested" easily, (3) multiple searches or search refinements are frequently required to achieve success. The purpose of this session is to familiarize attendees with a new generation of Radiology specific search and decision support tools that are geared towards providing high quality Radiology-centric search results to the desktop with a minimum of effort by the user. Novel presentation methods which aggregate information from multiple sources (ie. mashups) in a single portal will also be featured. This format allows users to consume content more efficiently than through conventional means.

Moving toward a Hospital-wide HL7-based Semantic Search Engine for Patient Information

Our hospital-wide patient information search engine was successful in indexing radiology reports as well as extracting semantic metadata from the content. Such Web-based tools can provide decision support at the point of care and offer robust capabilities for data-mining and retrospective data retrieval.

SESSION: Continuing Medical Education in the Clinical Practice (Basic Imaging Informatics)
YottaLook™: How to Avoid Searching for Content in All the Wrong Places?

Yottalook is a Web search engine that allows imaging specialists to obtain radiology-specific content and images from both the Internet and within the enterprise ( In this refresher course we will demonstrates the use and applications of a medical imaging search engine that identifies and retrieves online peer-reviewed content (including images) not indexed by generic search engines. Users will also learn how Yottalook enhances the search experience by analyzing user queries and modifying them in real time with RadLex-driven ontologies.

New Yottalook Journals Engine

With the newest update, we have introduced beta version of a new search engine, "Journals". Our new Journals engine allows users to search within radiology journals. Similar to our other engines, we have allowed options to filter by imaging modalities. Additional special filters exist, including "Review Articles", "Related Articles" and "Repeat Search in This Journal Only" options. We have used same query expansion technique employed in other Yottalook engines to increase relevance of search results. The "More..." button allows users ability to view the entire abstract without having to click on the search result.

What if you do not want to limit your search just to the radiology journals? Right underneath the search box, you will notice "Radiology Only" as well as "Search All" options. Radiology Only is selected by default, but one can click on "Search All" to expand search to include non-radiology journals as well.

We hope users will find this new search engine useful. Please feel free to provide your feedback as we want to constantly improve this beta engine.

New Revised Yottalook!

I haven't blogged for a while, but we have been very busy this year working on many new features; the updates throughout the year have been small. Last night, we did a major update to include many new features we have been working on this year.

The first thing you will notice is our new design. We have returned to a more simple layout.

You will also notice that we have added a brand new engine: "Journals". This is a new engine that will allow users to search journal articles. It will give you options to search either just the radiology journals or all the other journals. Think of it as our Google Scholar-like engine. However, this engine is not based on Google, allowing us more control over the search results. I will blog about this new engine separately later.

The Images engine has been updated to include now more than 750,000 images. It contains new radiology images upto November of this year. Due to the update, you will notice that a lot of the results will say "Subscription May Be Required". This is our warning to the user that the journal content shown likely requires a subscription to view the full content. If you are using this engine and either have a subscription to that particular journal or are coming from an academic site, you shouldn't have issue accessing the content. However, many of you do not have subscriptions to these journals. While we want to give higher ranking to more recent content, we are sensitive to this reality, and as a result, we have implemented a new filter called, "No Subscription Mode". By turning this on, the engine will try to maximize results that do not require subscription first; you will still see some but the result sets should be more optimal for those desiring this option. More changes have been made to the Images engine, but again I will blog about this separately later.
