Context-awareness is becoming an important foundation of adaptive mobile systems, however, techniques for discovering contextually relevant Web content and Smart Devices (i.e., Smart Resources) remain consigned to small-scale deployments. To address this limitation, this paper introduces Ambient Ocean, a Web search engine for context-aware Smart Resource discovery. Ocean provides scalable mechanisms...
Keyword based search scheme imposes the problem of representing a lot of web pages in the search engines. Query expansion with relevant words increases the performance of search engines, but finding and using the relevant words is an open problem. In this research we describe a new model for query expansion which employs user context and semantic concepts to discover new words for obtaining accurate...
This paper briefly presents our Information Retrieval and Indexing System (IRIS), and how it adapts to support game engine components. We describe a conceptual game, Chasers of the Lost Data, to demonstrate how pervasive games elements interact with content and user context detection, enabling a broad range of game applications. The presented game combines physical, sensorial and contextual information...
Recommender system is mainly based on collaborative filtering algorithms in social network, where it takes folksonomy as basic data structure. Collaborative filtering as a classical method of information retrieval has been also used in helping people to deal with information overload in folksonomies system. When context is taken into account, there might be difficulties when it comes to making recommendations...
Software reuse is considered as a prominent strategy for software development productivity improvement. However, there are many cases of software reuse adoption failure. One of the main factors for software reuse failure is the “no attempt to reuse” issue, which is highly influenced by the effort needed to find reusable artifacts. In this sense, this paper presents the definition, the implementation...
In this paper we introduce a new framework for the development of context-aware knowledge by integrating the user's digital and physical environment. The developed knowledge can contribute to solve problems and challenges of wireless sensor networks within a context that is described by additional cyber-content. Sensor networks are exposed, intentionally or not, to dynamically changing network structures...
Now a day's video blogs are playing an important role. To effectively manage the vlogs and make them more conveniently accessible for users is a challenging problem. In this paper we proposed a novel vlog management model which is consists of two stages: annotation and search. In Vlog annotation, we extract informative keywords not only from the textual content of the target vlog itself but also from...
Deeply meanings of Chinese poems are hard to understand for novices. Motivating from the proverb ??A picture is worth a thousand words??, poetry composition together with relevant multimedia is proposed to assist people in understanding Chinese poems. Learning in this way, the format of poetry and context of learning environment can be used to provide composition suggestions. Therefore, how to assist...
If software engineering tools are not "properly integrated", they can reduce engineers' productivity. Associating and retrieving information scattered across the tools become unsystematic and inefficient. Our work provides empirical evidence on what is a "poor" and a "proper" tool integration, focusing on practitioners' perspectives. We interviewed 62 engineers and analyzed...
Supporting dynamic attributes is critical in high quality Web service discovery. Presently, the methods used for service discovery assume that the world is static and, therefore, do not support attributes that are dynamic in nature. It is important to note that a service is characterized by both static and dynamic attributes. High quality Web service discovery requires detailed service context models...
Mobile-enabled social networks applications are becoming increasingly popular. Most of the current social network applications have been designed for high-end mobile devices, and they rely upon features such as GPS, capabilities of the World Wide Web, and rich media support. However, a significant fraction of mobile user base, especially in the developing world, own low-end devices that are only capable...
Current information service systems are built to serve all users, independent of the special needs of any individual user in different situations. Personalized information service aims at improving the retrieval process by taking into account the particular interests of individual users. However, not all user preferences are relevant in all situations, and they should be understood in context with...
With the emergence of pervasive computing environments, mobile information sharing and retrieval is becoming an exciting domain that challenges information scientists. In this paper, we describe a hybrid peer to peer context-aware framework for building mobile information sharing applications. A scalable and flexible architecture based on JXTA is presented. The architecture called "JHPeer"...
In the last decades, various storage and retrieval systems have been introduced to help the user find the relevant information for which he/she seeks. The very recent trend is the integration of the contextual information. This technique has gained popularity in various fields, such as e-learning, ubiquitous computing, and artificial intelligent, but hardly exploited in software reuse where the storage...
With the prevalence of pervasive devices, plenty of applications need to support context awareness. Due to the heterogeneity of context information, it is necessary to provide a set of common vocabularies with shared semantics. Based on above requirements, the paper presents an architecture of ontology-based context-aware application in pervasive environment. In the architecture context processing...
