System to predict bipolar disorder crises analysing massive data

Durante el desarrollo del proyecto he aprendido sobre Big Data, Android y MongoDB mientras que ayudaba a desarrollar un sistema para la predicción de las crisis del trastorno bipolar mediante el análisis masivo de información de diversas fuentes. En concreto hice una parte teórica sobre bases de datos NoSQL, Streaming Spark y Redes Neuronales y después diseñé y configuré una base de datos MongoDB para el proyecto del trastorno bipolar. También aprendí sobre Android y diseñé y desarrollé una aplicación de móvil en Android para recoger datos para usarlos como entrada en el sistema de predicción de crisis. Una vez terminado el desarrollo de la aplicación también llevé a cabo una evaluación con usuarios.

Social machines dictating social behaviors – When context is missing what is the fallout of uberveillance?

Abstract: In the mid-1990s when I worked for a telecommunications giant I struggled to gain access to basic geodemographic data. It cost hundreds of thousands of dollars at the time to simply purchase a tile of satellite imagery from Marconi, and it was often cheaper to create my own maps using a digitizer and A0 paper maps. Everything from granular administrative boundaries to right-of-ways to points of interest and geocoding capabilities were either unavailable for the places I was working in throughout Asia or very limited. The control of this data was either in a government’s census and statistical bureau or was created by a handful of forward thinking corporations. Twenty years on we find ourselves inundated with data (location and other) that we are challenged to amalgamate, and much of it still “dirty” in nature. Open data initiatives such as ODI give us great hope for how we might be able to share information together and capitalize not only in the crowdsourcing behavior but in the implications for positive usage for the environment and for the advancement of humanity. We are already gathering and amassing a great deal of data and insight through excellent citizen science participatory projects across the globe. In early 2015, I delivered a keynote at the Data Made Me Do It conference at UC Berkeley, and in the preceding year an invited talk at the inaugural QSymposium. In gathering research for these presentations, I began to ponder on the effect that social machines (in effect, autonomous data collection subjects and objects) might have on social behaviors. I focused on studying the problem of data from various veillance perspectives, with an emphasis on the shortcomings of uberveillance which included the potential for misinformation, misinterpretation, and information manipulation when context was entirely missing. As we build advanced systems that rely almost entirely on social machines, we need to ponder on the risks associated with following a purely technocratic approach where machines devoid of intelligence may one day dictate what humans do at the fundamental praxis level. What might be the fallout of uberveillance? Bio: Dr Katina Michael is a professor in the School of Computing and Information Technology at the University of Wollongong.

Prestanda av användargränssnitt i cross-platform-appar

Syftet med denna studie är att undersöka fördröjningsskillnader inom användargränssnitt mellan native­utvecklade appar (utveckling till varje plattform) och appar av typen generated apps. Eftersom arbetet syftar till att bidra med information om prestanda ansågs en experimentell metod vara det bästa valet. Mätning av laddningstider gjordes med hjälp av en videokamera som filmade utförandet av experimenten vilket gjorde metoden simpel och liknar det som en användare kommer att uppleva. Avgränsning till plattformarna Android och iOS gjordes där Xamarin valdes som ramverk inom tekniker som skapar generated apps. Mätdata från experiment som undersökte laddningstider, experiment med användare som hanterade listors respons samt undersökning av CPU­ och minnesanvändning tyder på ett återkommande mönster. Xamarin Forms med XAML är den teknik som presterat sämst under experimenten som sedan följs av Xamarin Forms. Xamarin Android/iOS hade inte lika stora prestandaförluster jämfört med native­utvecklade delar. Generellt hanterar Xamarin Forms telefonens resurser sämre än vad Xamarin Android/iOS och native gör. Resultat från studien kan användas som beslutsstöd vid val av teknik. Studien bidrar även med data som kan användas vid vidare forskning inom området.

On the application of contextual IoT service discovery in Information Centric Networks

The continuous flow of technological developments in communications and electronic industries has led to the growing expansion of the Internet of Things (IoT). By leveraging the capabilities of smart networked devices and integrating them into existing industrial, leisure and communication applications, the IoT is expected to positively impact both economy and society, reducing the gap between the physical and digital worlds. Therefore, several efforts have been dedicated to the development of networking solutions addressing the diversity of challenges associated with such a vision. In this context, the integration of Information Centric Networking (ICN) concepts into the core of IoT is a research area gaining momentum and involving both research and industry actors. The massive amount of heterogeneous devices, as well as the data they produce, is a significant challenge for a wide-scale adoption of the IoT. In this paper we propose a service discovery mechanism, based on Named Data Networking (NDN), that leverages the use of a semantic matching mechanism for achieving a flexible discovery process. The development of appropriate service discovery mechanisms enriched with semantic capabilities for understanding and processing context information is a key feature for turning raw data into useful knowledge and ensuring the interoperability among different devices and applications. We assessed the performance of our solution through the implementation and deployment of a proof-of-concept prototype. Obtained results illustrate the potential of integrating semantic and ICN mechanisms to enable a flexible service discovery in IoT scenarios.

METADATOS PARA LA SOCIEDAD DE LA INFORMACIÓN: ENCONTRANDO LA AGUJA EN EL PAJAR

Los metadatos son llaves para la categorización de información en los servicios digitales. En esencia se trata de catalogación y clasificación de información y su uso constituye una de las mejores prácticas en la gestión de información y de la misma manera que los catálogos y OPAC’s impacta en mejores servicios a los usuarios sean éstos de bibiotecas virtuales, e-gobierno, e-aprendizaje o e-salud; asimismo son la base para futuros desarrollos como la Web Semántica.El tema es de particular interés a los bibliotecarios ya que como organizadores del conocimiento conocen los esquemas de clasificación, reglas de registro de datos como las AACR2 y vocabularios especializados. En este documento se manejan algunos conceptos básicos al respecto y se comentan los pasos que América Latina está dando en este tema global.

Versioning Concept Schemes for Persistent Retrieval

Things change. Words change, meaning changes and use changes both words and meaning. In information access systems this means concept schemes such as thesauri or clas- sification schemes change. They always have. Concept schemes that have survived have evolved over time, moving from one version, often called an edition, to the next. If we want to manage how words and meanings - and as a conse- quence use - change in an effective manner, and if we want to be able to search across versions of concept schemes, we have to track these changes. This paper explores how we might expand SKOS, a World Wide Web Consortium (W3C) draft recommendation in order to do that kind of tracking.The Simple Knowledge Organization System (SKOS) Core Guide is sponsored by the Semantic Web Best Practices and Deployment Working Group. The second draft, edited by Alistair Miles and Dan Brickley, was issued in November 2005. SKOS is a “model for expressing the basic structure and content of concept schemes such as thesauri, classification schemes, subject heading lists, taxonomies, folksonomies, other types of controlled vocabulary and also concept schemes embedded in glossaries and terminologies” in RDF. How SKOS handles version in concept schemes is an open issue. The current draft guide suggests using OWL and DCTERMS as mechanisms for concept scheme revision.As it stands an editor of a concept scheme can make notes or declare in OWL that more than one version exists. This paper adds to the SKOS Core by introducing a tracking sys- tem for changes in concept schemes. We call this tracking system vocabulary ontogeny. Ontogeny is a biological term for the development of an organism during its lifetime. Here we use the ontogeny metaphor to describe how vocabularies change over their lifetime. Our purpose here is to create a conceptual mechanism that will track these changes and in so doing enhance information retrieval and prevent document loss through versioning, thereby enabling persistent retrieval.

L'HBIM semantico per la catalogazione e la fruizione dei Beni Culturali. Il caso studio della Chiesa di Santa Maria delle Vergini (MC) e la piattaforma Inception.

Questa tesi di laurea si pone l’obiettivo di investigare alcune delle nuove frontiere offerte dalla crescita sincretica e multidisciplinare dei linguaggi digitali applicati all’architettura e ai beni culturali. Si approfondiranno i concetti teorici fondamentali dell’informazione digitale: il web semantico come ambiente di scambio, i metadata come informazioni sui dati, i LOD (Link Open Data) come standard e fine. Per l’ambito dei beni culturali verranno presentati i temi di ricerca e sviluppo nel campo della catalogazione e fruizione digitali: ontologie, dizionari normalizzati aperti, database (Catalogo Digitale), etc. Per l’ambito edilizio-architettonico verrà introdotto l’Heritage Building Information Modeling (HBIM) semantico come metodologia multidisciplinare focalizzata su rilievo geometrico, modellazione, archiviazione e scambio di tutte le informazioni utili alla conoscenza e conservazione dei beni storici. Il punto d’incontro tra i due mondi è individuato nella possibilità di arricchire le geometrie attraverso la definizione di una semantica (parametri-metadati) relazionata alle informazioni (valori-dati) presenti nei cataloghi digitali, creando di fatto un modello 3D per architetture storiche con funzione di database multidisciplinare. Sarà presentata la piattaforma web-based Inception, sviluppata dall’omonima startup incubata come spinoff dall’Università di Ferrara, che, tra le diverse applicazioni e potenzialità, verrà utilizzata come strumento per la condivisione e fruizione, garantendo la possibilità di interrogare geometrie e metadati in continuità con i principi LOD. Verrà definito un workflow generale (procedure Scan2BIM, modellazione geometrica, definizione script per l’estrazione automatica dei dati dal Catalogo Digitale, associazione dati-geometrie e caricamento in piattaforma) successivamente applicato e adattato alle precise necessità del caso studio: la Chiesa di S. Maria delle Vergini (MC), su commissione dell’ICCD referente al MiBACT.
