Context-Aware Recommendation Systems in Mobile Environments

Nowadays, the huge amount of information available may easily overwhelm users when they need to take a decision that involves choosing among several options. As a solution to this problem, Recommendation Systems (RS) have emerged to offer relevant items to users. The main goal of these systems is to recommend certain items based on user preferences. Unfortunately, traditional recommendation systems do not consider the user’s context as an important dimension to ensure high-quality recommendations. Motivated by the need to incorporate contextual information during the recommendation process, Context-Aware Recommendation Systems (CARS) have emerged. However, these recent recommendation systems are not designed with mobile users in mind, where the context and the movements of the users and items may be important factors to consider when deciding which items should be recommended. Therefore, context-aware recommendation models should be able to effectively and efficiently exploit the dynamic context of the mobile user in order to offer her/him suitable recommendations and keep them up-to-date.The research area of this thesis belongs to the fields of context-aware recommendation systems and mobile computing. We focus on the following scientific problem: how could we facilitate the development of context-aware recommendation systems in mobile environments to provide users with relevant recommendations? This work is motivated by the lack of generic and flexible context-aware recommendation frameworks that consider aspects related to mobile users and mobile computing. In order to solve the identified problem, we pursue the following general goal: the design and implementation of a context-aware recommendation framework for mobile computing environments that facilitates the development of context-aware recommendation applications for mobile users. In the thesis, we contribute to bridge the gap not only between recommendation systems and context-aware computing, but also between CARS and mobile computing.<br /

Third International Symposium on Space Mission Operations and Ground Data Systems, part 2

Under the theme of 'Opportunities in Ground Data Systems for High Efficiency Operations of Space Missions,' the SpaceOps '94 symposium included presentations of more than 150 technical papers spanning five topic areas: Mission Management, Operations, Data Management, System Development, and Systems Engineering. The symposium papers focus on improvements in the efficiency, effectiveness, and quality of data acquisition, ground systems, and mission operations. New technology, methods, and human systems are discussed. Accomplishments are also reported in the application of information systems to improve data retrieval, reporting, and archiving; the management of human factors; the use of telescience and teleoperations; and the design and implementation of logistics support for mission operations. This volume covers expert systems, systems development tools and approaches, and systems engineering issues

Evolutionary genomics : statistical and computational methods

This open access book addresses the challenge of analyzing and understanding the evolutionary dynamics of complex biological systems at the genomic level, and elaborates on some promising strategies that would bring us closer to uncovering of the vital relationships between genotype and phenotype. After a few educational primers, the book continues with sections on sequence homology and alignment, phylogenetic methods to study genome evolution, methodologies for evaluating selective pressures on genomic sequences as well as genomic evolution in light of protein domain architecture and transposable elements, population genomics and other omics, and discussions of current bottlenecks in handling and analyzing genomic data. Written for the highly successful Methods in Molecular Biology series, chapters include the kind of detail and expert implementation advice that lead to the best results. Authoritative and comprehensive, Evolutionary Genomics: Statistical and Computational Methods, Second Edition aims to serve both novices in biology with strong statistics and computational skills, and molecular biologists with a good grasp of standard mathematical concepts, in moving this important field of study forward

L'informatica giuridica in Italia. Cinquant'anni di studi, ricerche ed esperienze

Nel panorama editoriale nazionale mancava un volume che ricostruisse la storia dell'informatica giuridica (IG) in Italia, esigenza sentita da più parti anche fuori dai nostri confini. Partendo da questa constatazione, è nata l'idea di offrire, in un'opera collettanea, una panoramica sull'origine ed evoluzione dell'IG, in cui confluiscano i contributi dei veri protagonisti di questa storia. Il volume raccoglie infatti le riflessioni, le esperienze, i progetti del nostro Paese attraverso i maggiori esperti e le più importanti istituzioni che hanno lavorato attivamente allo sviluppo di questa disciplina, intesa nel significato di IG in senso stretto, o informatica del diritto. Per offrire uno sguardo oltre i confini nazionali, l'opera include, sotto forma di interviste, anche le riflessioni dei maggiori studiosi ed esperti provenienti dai cinque continenti. La parte finale è dedicata alle sfide e opportunità che i ricercatori dell'ITTIG - Istituto di Teoria e Tecniche dell'Informazione Giuridica del CNR individuano nel rapporto tra diritto e tecnologie informatiche. In questo lungo percorso, infatti, la storia dell'IG si intreccia con quella scientifica dell'Istituto che da sempre gioca un ruolo centrale nel contesto nazionale e internazionale. Il volume non vuole essere un manuale, ma una fonte di riferimento per tutti coloro che si interessano della materia. La trattazione dei vari argomenti ha infatti un taglio soprattutto storico, non rifuggendo dalle esperienze personali di ogni singolo autore. Si auspica che il lettore ricavi dall'opera non solo l'evoluzione storica dell'IG in Italia, ma anche lo spirito, l'atmosfera che aleggiava in quegli anni

UX Latam: historias sobre definición y diseño de servicios digitales

Hace ya varios años que, en pláticas informales con colegas profesionales de UX de distintos países, surgían dos ideas recurrentes. La primera: los latinoamericanos necesitamos colaborar más. La segunda: existen muchos casos de éxito que no están documentados. Año tras año, decíamos «debería existir un libro», quizá solo a modo de deseo, para cuando hubiera algo de tiempo. Fueron cuatro o cinco años en los que fuimos madurando la idea. La sinergia y el enfoque en las problemáticas específicas de los latinos es algo que no termina de consolidarse. Se han hecho importantes esfuerzos aislados, como el UX Lat 2019 que la UXPA organizó en Chile (UXPA, 2019). En esa instancia, profesionales de muchos países comprometidos con mejorar la sociedad a través del diseño firmaron una Declaratoria Iberoamericana de UX. Sin embargo, la pandemia limitó su seguimiento. La misma pandemia fue uno de los factores que impulsó este libro. A inicios de marzo de 2020, al terminar mi doctorado, sentía que tenía tiempo de sobra en mis manos. Conversando con Freddy Linares, presidente del capítulo UXPA Perú y director de Neurometrics, consideramos que era un momento idóneo para escribir el libro
