The rise in business and electronic transactions using the web as a medium has driven the widespread use of recommendation systems across all domains. Recommendation systems generate suggestions for the travel and tourism industry, particularly hotels or services, centered on user interests and preferences. Relevant information collection, organization, processing vast quantities of string data, efficient data retrieval, and computational complexity in handling information overload are key issues to be addressed in a recommendation system. This work proposes a novel approach, using encoded bit vectors, to process information on hotel amenities and features extracted from Tripadvisor. Hotel amenities at different locations are organized and stored, based on the priority of the location, using the most significant bit and least significant bit. The amenities are prioritized dynamically thereafter, based on the location, and unique amenities accorded greater preference than the ones routinely offered at most hotels. Encoded bit vectors are utilized for information retrieval and precise hotel recommendations made, based on user interest rather than the string processing method that is ineffective where scalable data are concerned. Finally, the recommended hotels are ranked with user-centric personalized recommendations. These high-speed, efficient, and scalable algorithms are ideal for incrementally updating data. They also facilitate fast, flawless IR and query processing, along with appropriate hotel recommendations. The theoretical evaluation shows that the proposed method aids quick query processing and retrieval. The experimental assessment shows that hotels recommended by the proposed bit vector recommendation system have a higher accuracy on par with user and expert recommendations.

Pulmonary lymphoid malignancies comprise various entities, 80% of them are pulmonary marginal zone B-cell lymphomas (PMZL). So far, little is known about point mutations in primary pulmonary lymphomas. We characterized the genetic landscape of primary pulmonary lymphomas using a customized high-throughput sequencing gene panel covering 146 genes. Our cohort consisted of 28 PMZL, 14 primary diffuse large B-cell lymphomas (DLBCL) of the lung, 7 lymphomatoid granulomatoses (LyG), 5 mature small B-cell lymphomas and 16 cases of reactive lymphoid lesions. Mutations were detected in 22/28 evaluable PMZL (median 2 mutation/case); 14/14 DLBCL (median 3 mutations/case) and 4/7 LyG (1 mutation/case). PMZL showed higher prevalence for mutations in chromatin modifier-encoding genes (44% of mutant genes), while mutations in genes related to the NF-kappa B pathway were less common (24% of observed mutations). There was little overlap between mutations in PMZL and DLBCL.MALT1rearrangements were more prevalent in PMZL thanBCL10aberrations, and both were absent in DLBCL. LyG were devoid of gene mutations associated with immune escape. The mutational landscape of PMZL differs from that of extranodal MZL of other locations and also from splenic MZL. Their landscape resembles more that of nodal MZL, which also show a predominance of mutations of chromatin modifiers. The different mutational composition of pulmonary DLBCL compared to PMZL suggests that the former probably do not present transformations. DLBCL bear more mutations/case and immune escape gene mutations compared to LyG, suggesting that EBV infection in LyG may substitute for mutations.
