A Tool Support for Web Applications Adaptation Using Navigation History

Currently the Web is a platform for performing complex tasks which involve dealing with different Web applications. However users still have to face these tasks in a handcrafted way. In this paper we present a novel approach that combines concern-sensitive adaptation and navigation history to improve the user experience while performing a task. We have developed some simple though powerful tools for applying this approach to some typical tasks such as trip planning and house rental. We illustrate the paper with a simple though realistic case study and compare our work with others in the same field.Publicado en Lecture Notes in Computer Science book series (vol. 6949).Laboratorio de Investigación y Formación en Informática Avanzad

Location-based Social Network for Cities & Neighbourhood Sustainable Development

Online Social Network (OSN) is categorized as Web 2.0 which is defined by O'Reilly in 2004, is the idea of mutually maximizing collective intelligence and added value for each participant by dynamic information sharing and creation. Current trend sbows that the next big thing in OSN is Location-based Social Networking (LBSN) which is the composite of OSN and Location-based Service (LBS). The goal of this paper is to study on Malaysian online social behaviour and to explore what are the key technologies of LBSN to support the development of neighbourhoods where residents feel a sense of connection to their local community and ability to engage in that community. Problems and opportunities identified are: I) Lack of research has been done to nnderstand Malaysian online social behavior in the context of cities & neighbourhood development, 2) Modem societies are said to lives in a condition of individualism and 3) Malaysia has strong networked community and there are a number of social Application Programming Interface (API) which provide a great opportunities for developers to create an application which can support the idea of smart, liveable and sustainable cities. The objectives of the research are: 1) To study on Malaysian social behavior in using Location-based Social Network (LBSN) , motivation for participation and pattern of use, 2) To identifY and understand key technologies of LBSN, and 3) To design an engaging LBSN which leverage on key technologies for neighbourhood and cities' sustainable development. Survey instrument is used as data collection tool to investigate the Malaysian online social behaviour and gauge their views on civil issues such as crime in their residential. Interview also is carried out to the owner of existing crime mapping system to identifY the gaps and opportunities for improvements. This research discovers that Malaysians are socially active in online community network and have strong civic conscious to make our neighbourhood works better. Govermnent shonld look forward into open data for beneficial of public. With proper neighbourhood planning, it will contribute to sustainable community which can help country's development

Ontology-based end-user visual query formulation: Why, what, who, how, and which?

Value creation in an organisation is a time-sensitive and data-intensive process, yet it is often delayed and bounded by the reliance on IT experts extracting data for domain experts. Hence, there is a need for providing people who are not professional developers with the flexibility to pose relatively complex and ad hoc queries in an easy and intuitive way. In this respect, visual methods for query formulation undertake the challenge of making querying independent of users’ technical skills and the knowledge of the underlying textual query language and the structure of data. An ontology is more promising than the logical schema of the underlying data for guiding users in formulating queries, since it provides a richer vocabulary closer to the users’ understanding. However, on the one hand, today the most of world’s enterprise data reside in relational databases rather than triple stores, and on the other, visual query formulation has become more compelling due to ever-increasing data size and complexity—known as Big Data. This article presents and argues for ontology-based visual query formulation for end-users; discusses its feasibility in terms of ontology-based data access, which virtualises legacy relational databases as RDF, and the dimensions of Big Data; presents key conceptual aspects and dimensions, challenges, and requirements; and reviews, categorises, and discusses notable approaches and systems

Mashup Ecosystems: Integrating Web Resources on Desktop and Mobile Devices

The Web is increasingly used as an application platform, and recent development of it has introduced software ecosystems where different actors collaborate. This collaboration is international from day one, and it evolves and grows rapidly. In web ecosystems applications are provided as services, and interdependencies between ecosystem parts can vary from very strong and obvious to loose and recondite. Mashups -- web application hybrids that combine resources from different services into an integrated system that has increased value from user perspective -- are exploiting services of the Web and creating ecosystems where end-users, mashup authors, and service providers collaborate. The term "resources" is used here in a broad sense, and it can refer to user's local data, infinite content of the Web, and even executable code. This dissertation presents mashups as a new breed of web applications that are intended for parsing the web content into an easily accessed form on both regular desktop computers as well as on mobile devices. Constantly evolving web technologies and new web services open up unforeseen possibilities for mashup development. However, developing mashups with current methods and tools for existing deployment environments is challenging. First, the Web as an application platform faces numerous shortcomings, second, web application development practices in general are still immature, and third, development of mashups has additional requirements that need to be addressed. In addition, mobility sets even more challenges for mashup authoring. This dissertation describes and addresses numerous issues regarding mashup ecosystems and client-side mashup development. To achieve this, we have implemented technical research artifacts including mashup ecosystems and different kinds of mashup compositions. The artifacts are developed with numerous runtime environments and tools and targeted at different end-user platforms. This has allowed us to evaluate methods, tools, and practises used during the implementation. As result, this dissertation identifies the fundamental challenges of mashup ecosystems and describes how service providers and mashup ecosystem authors can address these challenges in practice. In addition, example implementation of a specialized multimedia mashup ecosystem for mobile devices is described. To address mashup development issues, this dissertation introduces practical guidelines and a reference architecture that can be applied when mashups are created with traditional web development tools. Moreover, environments that can be used on mobile devices to create mashups that have access to both web and local resources are introduced. Finally, a novel approach to web software development -- creating software as a mashup -- is introduced, and a realization of such concept is described

Aggregated search: a new information retrieval paradigm

International audienceTraditional search engines return ranked lists of search results. It is up to the user to scroll this list, scan within different documents and assemble information that fulfill his/her information need. Aggregated search represents a new class of approaches where the information is not only retrieved but also assembled. This is the current evolution in Web search, where diverse content (images, videos, ...) and relational content (similar entities, features) are included in search results. In this survey, we propose a simple analysis framework for aggregated search and an overview of existing work. We start with related work in related domains such as federated search, natural language generation and question answering. Then we focus on more recent trends namely cross vertical aggregated search and relational aggregated search which are already present in current Web search
