Novelty Track at IRIT-SIG
نویسندگان
چکیده
IRIT developed a new strategy in order to detect the relevant sentences that we did not try in a more general context of document retrieval but did try previously and partially in document categorization. In our approach a sentence is considered as relevant if it matches the topic with a certain level of coverage. This level of coverage depends on the category of the terms used in the texts. Three types of terms have been defined: highly relevant, lowly relevant and no relevant. With regard to the novelty part, a sentence is considered as novel when its levels of coverage with the previously processed sentences and with the bestmatching sentences do not exceed certain thresholds.
