  • 1. FeedNavigator – Medical Current Awareness Service Pasi Keski-Nisula It-Specialist National Library of Health Sciences -Terkko pasi.keski-nisula@helsinki.fi National Library of Health Sciences, Faculty of Medicine
  • 2. The Internet is a mountain size pile of journals and books where the best sellers are on the surface As the library people know best… National Library of Health Sciences, Faculty of Medicine
  • 3. What if all web sites would be catalogued into ”one huge library database”? No unique user interfaces of unique sites. No unique search functions of unique sites. No unique addresses and hundreds of bookmarks. Pasi Keski-Nisula, FeedNavigator – a Medical Current Awareness Service 27.06.2008 3
  • 4. What if all web sites would be catalogued into ”one huge library database”? One would have to use only a single service. One would have to learn only a single user interface. One would not have to learn many different search engine behaviors. Pasi Keski-Nisula, FeedNavigator – a Medical Current Awareness Service 27.06.2008 4
  • 5. ”Traditional” search engines try to do this Search engines collect data (words without meaning) from sites into a single searchable database. Search engines have been made for the web 1.0. -> Very limited semantics -> Not good enough for current awareness! Pasi Keski-Nisula, FeedNavigator – a Medical Current Awareness Service 27.06.2008 5
  • 6. Terkko realized back in 2004 that web feeds would become an important step for semantic web. TerkkoSiteSummary was a personal customizable web page. Collected tens of web feeds into one single web page. Without any database system. -> No advanced functions One year later Terkko introduced FeedNavigator.

  • 7. TerkkoSiteSummary Pasi Keski-Nisula, FeedNavigator – a Medical Current Awareness Service 27.06.2008 7
  • 8. FeedNavigator does it better Collects information from web feeds into a single searchable database. Web feed is a common text file which includes ”catalogued” information of the latest contents of web sites. A number of the sites that have web feeds rises continuosly. The most common formats are RSS, ATOM and PodCast which all are XML-formats. Pasi Keski-Nisula, FeedNavigator – a Medical Current Awareness Service 27.06.2008 8
  • 9. FeedNavigator collects web feed-data and allows to use this data in many ways Data is downloaded into FeedNavigator database A Client uses the database Pasi Keski-Nisula, FeedNavigator – a Medical Current Awareness Service 27.06.2008 9
  • 10. ”Traditional” Search Engines vs. FeedNavigator Collects data ->Collects information Very limited personalization. -> Efficient personalization. Database updates slowly and irregularly. ->Database updates all the time and regularly. Search functions are limited. ->Advanced search functions. (boolean,truncation...) Pasi Keski-Nisula, FeedNavigator – a Medical Current Awareness Service 27.06.2008 10
  • 11. ”Traditional” Search Engines vs. FeedNavigator Database includes obsolete data. ->No obsolete data. Multi-field. -> Single-field. Spam in search results. -> No spam in search results. No ads. One search engine has a monopoly. -> Uncommercial and free for all. Pasi Keski-Nisula, FeedNavigator – a Medical Current Awareness Service 27.06.2008 11
  • 12. FeedNavigator’s Sources 2784 journal feeds 73 medical topics (+ library sciences) 58 news feeds 326 blog feeds 477 university of Helsinki feeds Medical dissertations Helsinki Medical Publications Helka library catalogs Researchers publications Library evaluates and adds new feeds all the time into the system. Pasi Keski-Nisula, FeedNavigator – a Medical Current Awareness Service 27.06.2008 12
  • 13. FeedNavigator’s Data Almost half of million current references Source name Article title Link to article Description Author(s) DOI Time of downloading the item Some information added from other sources because the data is re-used in Scholar Chart –service. Impact Factors SCImago Journal Ranks (SJR) Hirsch-index Pasi Keski-Nisula, FeedNavigator – a Medical Current Awareness Service 27.06.2008 13
  • 14. FeedNavigator’s Data Re-use Data can be recycled in many ways: Feeds can be read with separate readers. Data can be exported into other web services: - Scholar Chart - DSpace - Intranet - LUX - Branch libraries - Other web sites… Pasi Keski-Nisula, FeedNavigator – a Medical Current Awareness Service 27.06.2008 14
  • 15. Some FeedNavigator’s Features Phrase searching & truncation and boolean operators. Updates 24/7 SFX-links. RefWorks-links (bibliographic management program). An article delivery service. Mobile interface. Works with all new mobile devices. It has a very simplified user interface, but has almost all the same functions as standard version. Pasi Keski-Nisula, FeedNavigator – a Medical Current Awareness Service 27.06.2008 15
  • 16. Basic Use of FeedNavigator User can customize a personal front page feed (MyFeed) by selecting user’s favorite medical publications and search keywords: 1. User can click the boxes in front of the source names to save favorite sources. 2. User can make a query and click a “MyFeed”-button to save search query. References can be saved to MyArticles page which is user’s own article repository. www.terkko.helsinki.fi/feednavigator Pasi Keski-Nisula, FeedNavigator – a Medical Current Awareness Service 27.06.2008 16
  • 17. FeedNavigator Ingredients RSS, ATOM and PodCast -feeds. Web 2.0 principle of continuous developing. Open standards and open software. Hosted and developed by Terkko. Linux, Apache, MySQL, PHP, XHTML, JavaScript, CSS… Dynamic timing of web feed downloads. The system keeps track how regularly publisher’s web feeds are updated and based on this data it adjusts dynamically the download frequencies of individual web feeds. This assures that there will be always enough network and computing resources to update all the feeds when new feeds are added. Pasi Keski-Nisula, FeedNavigator – a Medical Current Awareness Service 27.06.2008 17
  • 18. Web Feed Web feed is a XML-formatted text file. Includes multiple items which are ordered by publication date. Most common information: Link. Title. Description. Date. Other possible information, for example: Authors Language Category Etc. Pasi Keski-Nisula, FeedNavigator – a Medical Current Awareness Service 27.06.2008 18
  • 19. Web Feed The publisher has a file at the server and updates it frequently. The most popular web feed formats at the moment are different versions of RSS, Atom and Podcast. Maybe the most important downside is bandwidth consumption that the frequent downloading involves. Pasi Keski-Nisula, FeedNavigator – a Medical Current Awareness Service 27.06.2008 19
