Crowdsourcing refers to a distributed problemsolving model in which a crowd of undefined size is engaged in the task of solving a complex problem through an open call. This novel problem-solving model found its way into numerous applications on the web for voting, fund-raising, micro-works and wisdom-of-the-crowd scenarios. On the other hand, the shift of desktop users to mobile platforms in the post-PC...
For visually impaired users one of the major challenges is unassisted orientation and way-finding, especially in unexplored and potentially dangerous environments. The following work analyzes the issues stemmed from this problem and summarizes the merits and flaws of solutions available in literature. Afterwards, the research methodology is briefly described and the already achieved results are listed...
In this paper we present our Crowdsourced Linked Open Data Architecture (CLODA), a first attempt to combine crowdsourcing, localization and location-based services to generate, collect, validate and relate real-world, geo-spatial and multi-dimensional information using smartphones and other mobile devices. CLODA focuses on the construction of URI addressable, interlinked and semi-structured data following...
The mobile social networking application is aimed to build an application that helps users to check-in places and save the check-in data on cloud. Users can then show their trajectory on a web site. This project is ideal for people who spend a great deal of time traveling. The major benefit is the privacy that it offers and the algorithms that help the user to save the battery life. All the data is...
Cloud computing is emerging as the next big step in the design and deployment of an increasing number of distributed applications. On the other hand, smartphones are ruling the day in today's Post-PC world and are emerging as better players in offering services to consumers. Concurrent with the widespread adoption of cloud computing, smartphones have been clubbed with the power of cloud computing,...
We proposed the WFSTDM which is an expandable and adaptable dialogue management platform. The WFSTDM combines various WFSTs and enables us to develop new dialogue management WFSTs necessary for rapid prototyping of spoken dialogue systems. In this paper, we illustrate the outline of the WFSTDM and introduce the WFSTDM builder, a network-based spoken dialogue system development tool. In addition, we...
Recent success of mobile personal assistants deeply relies on the advancement in statistical automatic speech recognition (ASR) and spoken language understanding (SLU) technologies. This article describes practical design of ASR and SLU systems for "Shabette Concier", a voice-based personal assistant application commercially released by NTT docomo in Japan in March 2012. Utilization of a...
