In the last few years, many smart objects found in physical world are interconnected and communicate through existing internet infrastructure which creates a global network called Internet of Things (IoT). Research has shown substantial development solutions for wide range devices IoT platforms over past 6-7 years. However, each solution provides its own infrastructure, devices, APIs, data formats leading to interoperability issues. Such issues consequence critical such as vendor lock-in,...
Most Web applications are still developed ad hoc. One reason is the gap between established software design concepts and low-level implementation model. We summarize work on WebComposition, a model for application development, then introduce WebComposition Markup Language, an XML-based language that implements WCML embodies object-oriented principles such as modularity, abstraction encapsulation.
The Internet of Things (IoT) primary objective is to make a hyper-connected world for various application domains. However, IoT suffers from lack interoperability leading substantial threat the predicted economic value. Schema.org provides semantic structure heterogeneous data on Web. An extension this vocabulary domain (iot.schema.org) an ongoing research effort address Web (WoT). To design vocabulary, central challenge identify main topics (concepts and properties) automatically existing...
Abstract Body size is a key trait in ecology due to its influence on metabolism and many other life‐history traits that affect population community responses environmental variation as well ecosystem properties. The spectrum represents the relationship between abundance (or biomass) body size, independent of species identity. Size parameters, such slope or intercept, have been applied extensively indicators ecological status across multiple types. GLOSSAQUA dataset includes data from mainly...
In the light of Web 2.0 movement, web-based collaboration tools such as Google Docs have become mainstream and in meantime serve millions users. Apart from established collaborative web applications, numerous editors lack multi-user support even though they are suitable for work. Enhancing these single-user with shared editing capabilities is a costly endeavor since implementation infrastructure (accommodating conflict resolution, document synchronization, etc.) required. this paper, we...
ResearchAndMarkets wrote in their report on May 15, 2018, that up to 1.2 Trillion USD 2017 of products arecounterfeited goods. The estimated this damage globally at 1.82 2020 (RESEARCH ANDMARKETS, 2018). This paper does
With the success of Web 2.0 we are witnessing a growing number services and APIs exposed by Telecom, IT content providers. Targeting community and, in particular, application developers, service providers expose capabilities their infrastructures applications order to open new markets reach customer groups. However, due complexity underlying technologies, last step, i.e., consumption integration offered services, is non-trivial time-consuming task that still prerogative expert developers....
As the Web is increasingly used as a platform for heterogeneous applications, we are faced with new requirements to authentication, authorization and identity management. Modern architectures have control access not only single, isolated systems, but whole business-spanning federations of applications services. This task complicated by diversity today's specifications concerning e.g. privacy, system integrity distribution in web. an approach such problems, this paper, introduce solution...
Establishing efficient and intensive stakeholder collaboration is a key factor in Web application development projects. Therefore, the form of needs to be shifted from simple conversation valuable contribution, i.e. empowering stakeholders directly contribute effort. To achieve this, we introduce an approach combining Domain-specific Languages underlying technical platform.
This article discusses how modern Web-scale workflows can be built using a novel building block to integrated into social networks as well apps. routing principle fosters the integration of networking systems and mobile apps Web systems.
In our paper we overview methods and tools within traditional, semi-automatic, automatic approaches towards evaluation of website usability, which continues to gain in importance since the major search engines intensify its consideration it their results rankings. We note certain persisting ambiguities usability conceptualization for quantitative measurement a gap between more unprejudiced dimensions (effectiveness efficiency) fairly subjective aspect user satisfaction. However, argue that...
Despite several efforts for simplifying the composition process, learning required using existing mashup editors to develop mashups remain still high. In this paper, we describe how barrier can be lowered by means of an assisted development approach that seamlessly integrates automatic and interactive pattern recommendation techniques into platforms supporting easy end users. We showcase use such environment in context open-source platform Apache Rave. Results our user studies demonstrate...
It is crucial for the success of a search-driven web application to answer users' queries in best possible way. A common approach use click models guessing relevance search results. However, these are imprecise and waive valuable information one can gain from non-click user interactions. We introduce TellMyRelevance!---a novel automatic end-to-end pipeline tracking cursor interactions at client, analyzing learning according models. Yet, depend on layout results page involved, which makes...
