In this paper, a framework of player segmentation, tracking, highlighting and team classification in soccer game video is proposed. Main contributions consist of: 1) playfield modeling combining the Gaussian model with the dominant color extraction to segment the players/referees; 2) mean shift-based tracking with soft constraints from the foreground map to alleviate the shortcomings in handlin...

This paper describes the o cial runs of the Twenty-One group for TREC-7. The Twenty-One group participated in the ad-hoc and the cross-language track and made the following accomplishments: We developed a new weighting algorithm, which outperforms the popular Cornell version of BM25 on the ad-hoc collection. For the CLIR task we developed a fuzzy matching algorithm to recover from missing trans...

E-learning environments are mainly based on a range of delivery and interactive services. Web-based personalized learning recommender systems can, as a kind of services in e-learning environment, provide learning recommendations to students. This research proposes a framework of a personalized learning recommender system, which aims to help students find learning materials they would need to re...

Thornwaldt’s cyst occurs in the midline of the nasopharynx (space behind nasal cavity).Although it is relatively uncommon and majority are asymptomatic, it may cause significant symptoms. We present a case of young male who presented with history of snoring, stuffy nose and unusual heaviness in head. He had a history of irregular clinician consultation due to transferable nature of his job. On ...

XML documents annotated by different NLP tools accommodate multidimensional markup in a single hierarchy. To query such documents one has to account for different possible nesting structures of the annotations and the original markup of a document. We propose an expressive pattern language with extended semantics of the sequence pattern, supporting negation, permutation and regular patterns tha...

We describe Amharic-English cross lingual information retrieval experiments in the adhoc bilingual tracs of the CLEF 2006. The query analysis is supported by morphological analysis and part of speech tagging while we used different machine readable dictionaries for term lookup in the translation process. Out of dictionary terms were handled using fuzzy matching and Lucene[4] was used for indexi...

Acoustic feature similarity between search results has been shown to be very helpful for the task of spoken term detection (STD). A graph-based re-ranking approach for STD has been proposed based on the concept that search results, which are acoustically similar to other results with higher confidence scores, should have higher scores themselves. In this approach, the similarity between all sea...
