    • The present disclosure relates to a method for QE based on fuzzy logic considering top-retrieved document as relevance feedback documents for mining additional QE terms. The method includes mining additional QE terms upon considering top-retrieved document as relevance feedback documents by employing QE based on fuzzy logic; mining additional expansion terms upon calculating the degrees of importance of all unique terms of top-retrieved documents collection by selecting different QE terms selection methods; obtaining different relevance scores for each term; combining different weights of each term by using fuzzy rules to infer the weights of the additional query terms; and forming a query vector using the weights of the additional query terms and the weights of the original query terms to retrieve documents. 100> retrievirg relevant documents for original user query ina first iteration by using BM25 similarityfuriction with empirical pararnetersettirig 1 10 selectingtop n retrieved documents as PRF documents selectingall unique terms ofIPRFdocuments as thecandidate term setor term pool applyingstatistical-based, class-basedaridco-occurrence-based weightingapproaches for providing scores toall candidateterms cornbiringcandidate terms weightsobtained from statistical, class and co-occurrence-based approaches using three 108 fuzzylogiccontrollers (FLCs)infirstlevel fuzzy inferencesystem (FIS) combinirgweightingscores of FLC F arid _ usingone FLC in second level FISandcorbining W W andW weightingscores usingFLCj com biring weighting score of TFIDF with the weight obtained frornFLC, usingone LCin third-level FIS filteringnorn-relevant candidate terms upon applyrngsemanticfilteringapproach, whereinsemanticfilteredcandidate termisselected as additional query termsand used for expanding the userquery reweighting additional expansion terms by employing reweighting module "118 retrievirg ra nked list of releva nt documents for expa ended user query using additiona Iquery termssggested by FLBQEarid FLSBQE techniques Figure1 - ------------- r ------------------------- I Userquery arngFLCSMastUc Statuibased~ehd Search k ..

    • A method is dedicated to the transmission, via a transmission infrastructure (RC), using waves and with an access procedure relying on at least time division multiplexing, of contents of at least one channel, each of which is arranged in a base data layer and at least one layer of improvement data associated respectively with different transmission timeslots, and which are sliced into portions transmitted during the timeslots respectively associated with their layers. This method comprises i) the insertion at a chosen location of each portion to be transmitted of a base data layer, at the level of a chosen network layer, of at least one learning sequence processed according to a configuration scheme identical to that used to process said improvement data layer, and ii) on receipt of a portion of a base data layer of a content in a terminal (TC), the extraction of the learning sequence inserted at the level of a chosen network layer, then the estimation of the quality of reception on the basis of this extracted learning sequence, and the authorization to use the portion of the improvement data layer of the content when the estimated quality is greater than a chosen threshold.
