A workflow-centric research object bundles a workflow, the provenance of the results obtained by its enactment, other digital objects that are relevant for the experiment (papers, datasets, etc.), and annotations that semantically describe all these objects. In this paper, we propose a model to specify workflow-centric research objects, and show how the model can be grounded using semantic technologies and existing vocabularies, in particular the Object Reuse and Exchange (ORE) model and the Annotation Ontology (AO).We describe the life-cycle of a research object, which resembles the life-cycle of a scienti?c experiment.

La web vive un proceso de cambio constante, basado en una interacción mayor del usuario. A partir de la actual corriente de paradigmas y tecnologías asociadas a la web 2.0, han surgido una serie de estándares de gran utilidad, que cubre la necesidad de los desarrollos actuales de la red. Entre estos se incluyen los componentes web, etiquetas HTML definidas por el usuario que cubren una función concreta dentro de una página. Existe una necesidad de medir la calidad de dichos desarrollos, para discernir si el concepto de componente web supone un cambio revolucionario en el desarrollo de la web 2.0. Para ello, es necesario realizar una explotación de componentes web, considerada como la medición de calidad basada en métricas y definición de un modelo de interconexión de componentes. La plataforma PicBit surge como respuesta a estas cuestiones. Consiste en una plataforma social de construcción de perfiles basada en estos elementos. Desde la perspectiva del usuario final se trata de una herramienta para crear perfiles y comunidades sociales, mientras que desde una perspectiva académica, la plataforma consiste en un entorno de pruebas o sandbox de componentes web. Para ello, será necesario implementar el extremo servidor de dicha plataforma, enfocado a la labor de explotación, por medio de la definición de una interfaz REST de operaciones y un sistema para la recolección de eventos de usuario en la plataforma. Gracias a esta plataforma se podrán discernir qué parámetros influyen positivamente en la experiencia de uso de un componente, así como descubrir el futuro potencial de este tipo de desarrollos.---ABSTRACT---The web evolves into a more interactive platform. From the actual version of the web, named as web 2.0, many paradigms and standards have arisen. One of those standards is web components, a set of concepts to define new HTML tags that covers a specific function inside a web page. It is necessary to measure the quality of this kind of software development, and the aim behind this approach is to determine if this new set of concepts would survive in the actual web paradigm. To achieve this, it is described a model to analyse components, in the terms of quality measure and interconnection model description. PicBit consists of a social platform to use web components. From the point of view of the final user, this platform is a tool to create social profiles using components, whereas from the point of view of technicians, it consists of a sandbox of web components. Thanks to this platform, we will be able to discover those parameters that have a positive effect in the user experience and to discover the potential of this new set of standards into the web 2.0.

With the quick advance of web service technologies, end-users can conduct various on-line tasks, such as shopping on-line. Usually, end-users compose a set of services to accomplish a task, and need to enter values to services to invoke the composite services. Quite often, users re-visit websites and use services to perform re-occurring tasks. The users are required to enter the same information into various web services to accomplish such re-occurring tasks. However, repetitively typing the same information into services is a tedious job for end-users. It can negatively impact user experience when an end-user needs to type the re-occurring information repetitively into web services. Recent studies have proposed several approaches to help users fill in values to services automatically. However, prior studies mainly suffer the following drawbacks: (1) limited support of collecting and analyzing user inputs; (2) poor accuracy of filling values to services; (3) not designed for service composition. To overcome the aforementioned drawbacks, we need maximize the reuse of previous user inputs across services and end-users. In this thesis, we introduce our approaches that prevent end-users from entering the same information into repetitive on-line tasks. More specifically, we improve the process of filling out services in the following 4 aspects: First, we investigate the characteristics of input parameters. We propose an ontology-based approach to automatically categorize parameters and fill values to the categorized input parameters. Second, we propose a comprehensive framework that leverages user contexts and usage patterns into the process of filling values to services. Third, we propose an approach for maximizing the value propagation among services and end-users by linking a set of semantically related parameters together and similar end-users. Last, we propose a ranking-based framework that ranks a list of previous user inputs for an input parameter to save a user from unnecessary data entries. Our framework learns and analyzes interactions of user inputs and input parameters to rank user inputs for input parameters under different contexts.
Towards a web-based progressive handwriting recognition environment for mathematical problem solving

The emergence of pen-based mobile devices such as PDAs and tablet PCs provides a new way to input mathematical expressions to computer by using handwriting which is much more natural and efficient for entering mathematics. This paper proposes a web-based handwriting mathematics system, called WebMath, for supporting mathematical problem solving. The proposed WebMath system is based on client-server architecture. It comprises four major components: a standard web server, handwriting mathematical expression editor, computation engine and web browser with Ajax-based communicator. The handwriting mathematical expression editor adopts a progressive recognition approach for dynamic recognition of handwritten mathematical expressions. The computation engine supports mathematical functions such as algebraic simplification and factorization, and integration and differentiation. The web browser provides a user-friendly interface for accessing the system using advanced Ajax-based communication. In this paper, we describe the different components of the WebMath system and its performance analysis.

Because some Web users will be able to design a template to visualize information from scratch, while other users need to automatically visualize information by changing some parameters, providing different levels of customization of the information is a desirable goal. Our system allows the automatic generation of visualizations given the semantics of the data, and the static or pre-specified visualization by creating an interface language. We address information visualization taking into consideration the Web, where the presentation of the retrieved information is a challenge. ^ We provide a model to narrow the gap between the user's way of expressing queries and database manipulation languages (SQL) without changing the system itself thus improving the query specification process. We develop a Web interface model that is integrated with the HTML language to create a powerful language that facilitates the construction of Web-based database reports. ^ As opposed to other papers, this model offers a new way of exploring databases focusing on providing Web connectivity to databases with minimal or no result buffering, formatting, or extra programming. We describe how to easily connect the database to the Web. In addition, we offer an enhanced way on viewing and exploring the contents of a database, allowing users to customize their views depending on the contents and the structure of the data. Current database front-ends typically attempt to display the database objects in a flat view making it difficult for users to grasp the contents and the structure of their result. Our model narrows the gap between databases and the Web. ^ The overall objective of this research is to construct a model that accesses different databases easily across the net and generates SQL, forms, and reports across all platforms without requiring the developer to code a complex application. This increases the speed of development. In addition, using only the Web browsers, the end-user can retrieve data from databases remotely to make necessary modifications and manipulations of data using the Web formatted forms and reports, independent of the platform, without having to open different applications, or learn to use anything but their Web browser. We introduce a strategic method to generate and construct SQL queries, enabling inexperienced users that are not well exposed to the SQL world to build syntactically and semantically a valid SQL query and to understand the retrieved data. The generated SQL query will be validated against the database schema to ensure harmless and efficient SQL execution. (Abstract shortened by UMI.)^

The recent surge in scientific electronic journals began when libraries began having access to the WWW in the mid-1990s. The shift from paper to digital has affected the traditional alignment and role of the primary "stakeholders" -mainly authors, publishers, universities and libraries. The author offers a brief review of the history of the scholarly journal followed by the evolution of e-journals in during the past two decades. The article then focuses on the implications that these have had on traditional library processes and services such as selection, acquisitions, cataloguing, storage, preservation and user services. In the conclusion the author speculates on the long term effect of Web-based publishing on the format of the traditional scholarly journal as it has existed for over 300 years.

Single-page applications have historically been subject to strong market forces driving fast development and deployment in lieu of quality control and changeable code, which are important factors for maintainability. In this report we develop two functionally equivalent applications using AngularJS and React and compare their maintainability as defined by ISO/IEC 9126. AngularJS and React represent two distinct approaches to web development, with AngularJS being a general framework providing rich base functionality and React a small specialized library for efficient view rendering. The quality comparison was accomplished by calculating Maintainability Index for each application. Version control analysis was used to determine quality indicators during development and subsequent maintenance where new functionality was added in two steps. The results show no major differences in maintainability in the initial applications. As more functionality is added the Maintainability Index decreases faster in the AngularJS application, indicating a steeper increase in complexity compared to the React application. Source code analysis reveals that changes in data flow requires significantly larger modifications of the AngularJS application due to its inherent architecture for data flow. We conclude that frameworks are useful when they facilitate development of known requirements but less so when applications and systems grow in size.

Il problema dell'antibiotico-resistenza è un problema di sanità pubblica per affrontare il quale è necessario un sistema di sorveglianza basato sulla raccolta e l'analisi dei dati epidemiologici di laboratorio. Il progetto di dottorato è consistito nello sviluppo di una applicazione web per la gestione di tali dati di antibiotico sensibilità di isolati clinici utilizzabile a livello di ospedale. Si è creata una piattaforma web associata a un database relazionale per avere un’applicazione dinamica che potesse essere aggiornata facilmente inserendo nuovi dati senza dover manualmente modificare le pagine HTML che compongono l’applicazione stessa. E’ stato utilizzato il database open-source MySQL in quanto presenta numerosi vantaggi: estremamente stabile, elevate prestazioni, supportato da una grande comunità online ed inoltre gratuito. Il contenuto dinamico dell’applicazione web deve essere generato da un linguaggio di programmazione tipo “scripting” che automatizzi operazioni di inserimento, modifica, cancellazione, visualizzazione di larghe quantità di dati. E’ stato scelto il PHP, linguaggio open-source sviluppato appositamente per la realizzazione di pagine web dinamiche, perfettamente utilizzabile con il database MySQL. E’ stata definita l’architettura del database creando le tabelle contenenti i dati e le relazioni tra di esse: le anagrafiche, i dati relativi ai campioni, microrganismi isolati e agli antibiogrammi con le categorie interpretative relative al dato antibiotico. Definite tabelle e relazioni del database è stato scritto il codice associato alle funzioni principali: inserimento manuale di antibiogrammi, importazione di antibiogrammi multipli provenienti da file esportati da strumenti automatizzati, modifica/eliminazione degli antibiogrammi precedenti inseriti nel sistema, analisi dei dati presenti nel database con tendenze e andamenti relativi alla prevalenza di specie microbiche e alla chemioresistenza degli stessi, corredate da grafici. Lo sviluppo ha incluso continui test delle funzioni via via implementate usando reali dati clinici e sono stati introdotti appositi controlli e l’introduzione di una semplice e pulita veste grafica.

EUMETSAT (www.eumetsat.int) e’ l’agenzia europea per operazioni su satelliti per monitorare clima, meteo e ambiente terrestre. Dal centro operativo situato a Darmstadt (Germania), si controllano satelliti meteorologici su orbite geostazionarie e polari che raccolgono dati per l’osservazione dell’atmosfera, degli oceani e della superficie terrestre per un servizio continuo di 24/7. Un sistema di monitoraggio centralizzato per programmi diversi all’interno dell’ambiente operazionale di EUMETSAT, e’ dato da GEMS (Generic Event Monitoring System). Il software garantisce il controllo di diverse piattaforme, cross-monitoring di diverse sezioni operative, ed ha le caratteristiche per potere essere esteso a future missioni. L’attuale versione della GEMS MMI (Multi Media Interface), v. 3.6, utilizza standard Java Server Pages (JSP) e fa uso pesante di codici Java; utilizza inoltre files ASCII per filtri e display dei dati. Conseguenza diretta e’ ad esempio, il fatto che le informazioni non sono automaticamente aggiornate, ma hanno bisogno di ricaricare la pagina. Ulteriori inputs per una nuova versione della GEMS MMI vengono da diversi comportamenti anomali riportati durante l’uso quotidiano del software. La tesi si concentra sulla definizione di nuovi requisiti per una nuova versione della GEMS MMI (v. 4.4) da parte della divisione ingegneristica e di manutenzione di operazioni di EUMETSAT. Per le attivita’ di supporto, i test sono stati condotti presso Solenix. Il nuovo software permettera’ una migliore applicazione web, con tempi di risposta piu’ rapidi, aggiornamento delle informazioni automatico, utilizzo totale del database di GEMS e le capacita’ di filtri, insieme ad applicazioni per telefoni cellulari per il supporto delle attivita’ di reperibilita’. La nuova versione di GEMS avra’ una nuova Graphical User Interface (GUI) che utilizza tecnologie moderne. Per un ambiente di operazioni come e’ quello di EUMETSAT, dove l’affidabilita’ delle tecnologie e la longevita’ dell’approccio scelto sono di vitale importanza, non tutti gli attuali strumenti a disposizione sono adatti e hanno bisogno di essere migliorati. Allo stesso tempo, un’ interfaccia moderna, in termini di visual design, interattivita’ e funzionalita’, e’ importante per la nuova GEMS MMI.

online donde el contenido es creado por los propios usuarios mediante el uso de las tecnologías de la web 2.0, que facilitan la edición, la publicación y el intercambio de información, de tal manera que los social media están democratizando las comunicaciones. Según datos publicados por eMarketer, casi el 25% del total de la inversión publicitaria mundial para el 2014 estará dirigida a medios digitales. Los medios de comunicación tradicionales están sumidos desde algún tiempo en una profunda crisis. En los comienzos de Internet, los protagonistas de este sector han creído en la red como un medio de publicación de contenidos en una única dirección, esto es la web 1.0, personas conectándose a páginas web. El típico lector de revista y seminario se ha convertido en un nuevo consumidor con necesidades muy distintas. El lector de un medio tradicional se encuentra con contenido cerrado, sin posibilidad de ser filtrado, que busca dirigir su opinión. Con el método tradicional no es posible ni personalizar el contenido ni la experiencia de uso. De ahí el nacimiento de la web 2.0, personas conectándose a personas (redes sociales). En un futuro cercano, van a triunfar las empresas, sectores y marcas que sepan adaptarse a la llegada de los social media, y que además de desarrollar su línea de negocio habitual, se conviertan en plataformas para la conversación y la construcción de contenidos en colaboración. En este proyecto voy a desarrollar el caso particular de una empresa de telecomunicaciones con una estrategia que use los social media como plataforma de atención al cliente, y para interaccionar también con su almacén en DHL. Los servicios añadidos que dicha empresa de telecomunicaciones ofrece a sus seguidores, clientes externos e internos se pueden agrupar en las siguientes funcionalidades: Hacer un volcado del sistema de gestión de incidencias de una empresa de telecomunicaciones en las redes sociales, a través de mensajes privados. Dichos mensajes privados se enviarán a las páginas de Facebook y Twitter de los clientes. Seguimiento por parte del cliente de puestas en marcha de los nuevos servicios a través de mensajes privados en Facebook y Twitter. Mediante este servicio el cliente podrá comprobar a través de las redes sociales el estado de su pedido e intercambiar información de utilidad con la empresa. Desarrollar a través de las redes sociales una herramienta de marketing para interaccionar con los clientes y posibles seguidores. A través de los canales de los social media se proporciona a los seguidores información de valor sobre novedades del mercado de las telecomunicaciones, soporte técnico, dudas, consejos sobre implementaciones técnicas, equipos de telecomunicaciones,.etc.Es decir, crear una plataforma de conversación entre usuarios, que aporte a los seguidores conocimientos y soluciones útiles para la problemática de sus negocios. Usar Facebook como base de datos y medio de comunicación entre nuestra empresa de telecomunicaciones y el almacén externalizado en DHL. Supongo que la primera pregunta que debo responder sería, ¿por qué un cliente de una empresa de telecomunicaciones estaría interesado en seguir a su proveedor a través de redes sociales? Facebook tiene en 2014 1,28 billones de usuarios activos. Twitter, la cuarta plataforma social por número de usuarios tras Facebook, alcanzó los 255 millones de usuarios en los primeros meses de 2014. La segunda red social en número de seguidores es Youtube, con un billón de usuarios. El 61,5% de los usuarios de Facebook visita la red todos los días. Los twitteros envían 110 millones tweets por día, tienen fama de muy activos, especialmente por la mañana. En 60 días, se sube más contenido de vídeo a YouTube que el producido por las tres principales cadenas de televisión estadounidense durante 60 años. Como conclusión, las redes sociales están ganando cada día más terreno, es un entorno de comunicación bidireccional en auge cada vez más extendido, por lo cual los usuarios no tienen que dedicar tiempo extra a conocer la herramienta de atención al cliente de su empresa, al usar ésta un canal fácil, conocido, rápido, versátil y gratuito como son las redes sociales. ABSTRACT. Social media are platforms of online communication where content is created by users themselves using technologies of web 2.0, which facilitate the editing, publication and the exchange of information, so that the social media are democratizing communications. According to data published by eMarketer, nearly 25% of the total global ad spend for 2014 will target digital media. The traditional media are trapped for some time in deep crisis. In the early days of the internet, the players of the sector have believed in the network as a means of publishing content in a single direction, this is the web 1.0, connecting people to websites. The typical magazine reader has become a new consumer with very different needs. Traditional medium readers encounter a closed content, unable to be filtered, which seeks handle their opinion. The traditional method doesn’t allow to customize the content and user experience. Hence the birth of Web 2.0, connecting people to people. In the near future, will succeed companies, sectors and brands who can adapt to the advent of social media, and further to develop their line of business as usual, become platforms for conversation and building collaborative content. In this project I will develop the particular case of a telecommunications company with a strategy to use social media as a platform for Customer Service, and also to interact with DHL warehouse. The additional services that the company offers telecommunications followers, external and internal customers can be grouped into the following functionality: Make a dump of the incident management system of a telecommunications company in social networks through private messages. These private messages are sent Facebook and Twitter clients. Monitoring by the client launched new services through private messages on Facebook and Twitter. Through this service, customers can check through the social networks of your order status and share useful information with the company. Develop through social media as a marketing tool to interact with customers and potential followers.Our telco will provide to followers through social media channels valuable information on market developments in telecommunications, technical support, questions, advice on technical implementations, telecommunications equipment,etc. Then we create a platform for discussion between users, to provide followers useful knowledge and solutions to their business problems. Use Facebook as a database and means of communication between our telco and outsourced telecommunications in DHL warehouse. I guess the first question that must be answered is why a customer of a telecommunications company would be interested in following your provider via social networks. Facebook has 1.28 billion active users in 2014. Twitter, the fourth social platform for many users after Facebook reached 255 million users in the first months of 2014. The second social network on number of followers is YouTube, with a billion users. 61.5% of Facebook users visit the network every day. The twitter users send 110 million tweets per day, have a reputation for very active, especially in the morning. In 60 days, it is produced more video content to YouTube by the three major US television for 60 years. In conclusion, social networks are gaining more ground every day. It is an environment of two-way communication on the rise, so users do not have to spend extra time to learn the tool of Customer Care telco, by using this easy, known, fast, versatile and free channels as are social networks.
