This paper describes the general service recommendation process matched to the telecommunication service delivery characteristics of the Ubiquitous Consumer Wireless World (UCWW). The goal is to provide consumers with the ‘best’ service instances that match their dynamic, contextualized and personalized requirements and expectations, thereby aligning their usage of mobile services to the always best...
The proliferation of pervasive services requires advanced methods to adapt the service provision to the user's context. The author presents a hybrid statistical and semantic framework for interface selection and adaptation. The approach is to find the best compromise between urgency and privacy requirements, avoiding interference with the user's activities.
Driving is an integral part of our everyday lives, and the average driving time of people globally is increasing to 84 minutes everyday, which is a time when people are uniquely vulnerable. A number of research works have identified that mobile crowd sensing in vehicular social networks (VSNs) can be effectively used for many purposes and bring huge economic benefits, e.g., safety improvement and...
The discovery process has become an important task in the web service life cycle as the number of Mobile Web Services (MWS) has increased nowadays. However, discovering relevant MWS that can match a service request with the service offered has remained a major hindrance. The challenges are concerning the web service discovery with the limitation of mobile devices related to performance. On the other...
Location-based Services (LBS) are one of the longest-standing value-added services in the mobile communications industry. The location of a user is the fundamental factor shaping such services and is usually computed solely in terms of the physical location relying on Reverse Geocoding APIs. It does not take into consideration the semantics of the location, but rather only the geographic spatial information,...
Context-aware and semantic-based technologies have been successfully employed to improve multimedia management in mobile environments. Large sets of context-tagged images on the Web are a concrete example of this achievement. The authors present two mobile systems, MMedia2U and CAPTAIN, that take the concept of context-aware multimedia management beyond photo organization and annotation. CAPTAIN is...
Recently, mobile devices have become increasingly widespread. Through these mobile devices have appeared new requirements and opportunities. Technological developments within mobile devices led to the discovery of new ways to develop and implement applications that support communication between these devices. These applications often operate in context-sensitive environments and must work with temporal,...
Pervasive applications want to describe in simple ways which context information they need about users, and be notified when low level context matches specified constraints defined by semantic expressions. In this paper we report our experience while implementing our Context Query Language and using it in a real context framework to support mobile context-aware applications in two European-funded...
Recent rapid advancement in both pervasive mobile computing and cloud service has been driving numerous new applications in the ubiquitous media consumption. To provide mobile user with richer experiences, it is desired for the service providers to offer highly relevant recommendations of media content to the users by exploring user-user, user-media and user-context relationships. Furthermore, contemporary...
Context aware computing attains environments monitoring by means of sensors in order to provide relevant information or services according to the identified context. Nowadays, ad hoc wireless sensor networks for medical purposes are playing an increasing role within healthcare. Specifically, Body Sensor Networks (BSN) and Wireless Sensor Network, are being designed for prophylactic and follow-up monitoring...
This paper presents a method to enhance location awareness by using semantic composition of AT-LOCATION and PART-WHOLE semantic relations. The method generates axioms that infer new location relations based on relations that are extracted by a semantic parser. Experimental study with WordNet glosses shows that the method increases the amount of location knowledge by two orders of magnitude. The precision...
Situation awareness is a promising approach to recommend to a mobile user the most suitable resources for a specific situation. However, determining the correct user situation is not a simple task since users have different habits that may affect the way in which the situations arise. Thus, an appropriate tuning aimed at adapting the situation recognizer to the specific user is desirable to make a...
Microcontent is the prime resource and valuable asset of Web 2.0, rapid development of Mobile Commerce (MC) has enhanced the operational functionalities requirement among Mobile terminals, Servers, Knowledge Bases and other participants in many Web 2.0 applications, consequently making Micro content Management incompetent in the world of distributed environment. This issue gets further complicated...
High level context recognition and situation detection are enabling technologies for unobtrusive mobile computing systems. Significant progress has been made in processing and managing context information, leading to sophisticated frameworks, middlewares, and algorithms. Despite great improvements, context aware systems still require a significantly increased recognition accuracy for high-level context...
Information foraging and sensemaking with heterogeneous information are context-dependent activities. Thus visual analytics tools to support these activities must incorporate context. But, context is a difficult concept to define, model, and represent. Creating and representing context in support of visually-enabled reasoning about complex problems with complex information is a complementary but different...
In existing mobile content service systems, the study is quite rare on automatic situation-service rule construction. Hence, a method is proposed that the semantic association rules between situations and preferences are built by quantitative frequent marked lattice. Different recommendation rules can be extracted along multi-dimensional context routes from this lattice structure. It is propitious...
A challenge in the convergence of heterogeneous networks is how to combine the ubiquitous resources and provide the diversified individual services. By this, the vision of adaptive and context-aware service provision becomes possible and offers new opportunities for pervasive computing. In this paper, we describe an approach that addresses the convergence of wireless personal area and wide area networks...
In order to make mobile devices get Web Services continuity and stability, we propose a method called lazy strategy for efficient utilizing Web Services, which used as computing strategy when we encounter avalanche of expressions in runtime. Both the conception and technology as we known are just like an introduction or elimination approach that it solves the space explosion problem by type checking...
In this paper, we address the process of generating cartographic maps on-the-fly. Despite the existence of intensive research works, this process is still characterized by its complexity, time-consuming processing, and lack of flexibility. While web users are having an improved access to spatial data, mobile users are still facing problems in getting personalized maps that fit their limited display...
The quality of interaction with a mobile website is arguably influenced by the prevailing conditions of use. The characteristics of the latter have not been sufficiently addressed in HCI literature yet, partly because they cannot be easily controlled in a usability study. Drawing on multidisciplinary theories, we propose a model hypothesizing on the effects of environmental context on the usability...
