CWI at ImageCLEF 2008

چکیده
CWI used PF/Tijah, a flexible XML retrieval system, to evaluate image retrieval based on textual evidence in the context of the wikipediaMM task at ImageCLEF 2008. We employed a language modelling framework and found that the text associated with the Wikipedia images is a good source of evidence. We also investigated a length prior and found that biasing towards images with longer descriptions than the ones retrieved by our language modelling approach is not beneficial.

This paper introduces the IPAL participation at CLEF 2008 on the new TEL collection and on the ad-hoc photographic retrieval ImageClef. Following the changes in evaluation criterion this year in ImageClef, i.e. promoting diversity in the top ranked images, we have integrated the novelty measure in our similarity based system developed in ImageCLEF 2007. The novelty score is calculated between a...

UNLABELLED Cold water immersion (CWI) has become a popular means of enhancing recovery from various forms of exercise. However, there is minimal scientific information on the physiological effects of CWI following cycling in the heat. PURPOSE To examine the safety and acute thermoregulatory, cardiovascular, metabolic, endocrine, and inflammatory responses to CWI following cycling in the heat....
متن کاملOverview of the wikipediaMM task at ImageCLEF 2008
The wikipediaMM task provides a testbed for the system-oriented evaluation of ad-hoc retrieval from a collection of Wikipedia images. It became a part of the ImageCLEF evaluation campaign in 2008 with the aim of investigating the use of visual and textual sources in combination to improve the retrieval performance. This paper presents an overview over the wikipediaMM 2008 task’s resources, topi...

متن کاملEffect of immediate and delayed cold water immersion after a high intensity exercise session on subsequent run performance.
The purpose of the study was to determine the effects of cold water immersion (CWI) performed immediately or 3 h after a high intensity interval exercise session (HIIS) on next-day exercise performance. Eight male athletes performed three HIIS at 90%VO2max velocity followed by either a passive recovery (CON), CWI performed immediately post-exercise (CWI(0)) or CWI performed 3 h post-exercise (C...
