    Mobile users have the capability of accessing information anywhere at any time with the introduction of mobile browsers and mobile web search. However, the current mobile browsers are implemented without considering the characteristics of mobile searches. As a result, mobile users need to devote time and effort in order to retrieve relevant information from the web in mobile devices. On the other hand, mobile users often request information related to their surroundings, which is also known as context. This recognizes the importance of including context in information retrieval. Besides, the availability of the embedded sensors in mobile devices has supported the recognition of context. In this study, the context acquisition and utilization for mobile information retrieval are proposed. The "just-in-time" approach is exploited in which the information that is relevant to a user is retrieved without the user requesting it. This will reduce the mobile user's effort, time and interaction when retrieving information in mobile devices. In this paper, the context dimensions and context model are presented. Simple experiments are shown where user context is predicted using the context model

    Poster in the proceedingsThis paper describes an extensible core software element of a distributed, peer-to-peer system, which provides several facilities in order to help the implementation of collaborative, Web-based, distributed information storing and retrieval applications based on a decentralized P2P model. Moreover, after an architectural introduction of the core distributed software module, the Core Node, this paper describes a real application, named DART Node, based on it and designed and implemented within the DART (Distributed Agent-based Retrieval Tools) project, which carries out the idea of the design and implementation of a distributed, semantic and collaborative Web search engine, including mobile devices integration use cases.

    With the introduction of faster wireless networking technology, the emergence of wireless devices and mobile networking has opened up new business opportunity begin with e-commerce and now extends to mobile commerce (m-commerce). Basically, this Final Year Project proposed the development and implementation of the Mobile Information Kiosk in Mall using Wi-Fi- a mobile solution that satisfies shopping mall customer's need and busy working style. This report presents the research and study of the project as well as the outcome of the project that is Mobile Information Kiosk in Mall using Wi-Fi ' This ·project will address to the three problem statements which are larger shopping mall brings a larger number of shops, practicality of Web-site provided and last but not least network fees and charges. This followed by the objectives of the system that is to develop a system called " Mobile Information Kiosk in Mall using Wi-Fi" that can successfully aid visitors to find their desired retail stores or facilities or items in the shopping mall as well help visitors saving their time, money ,and effort. The scopes of the project are divided into two main parts that are to focus on information search and retrieval from system's database and also to focus on information display by providing the graphical mapping. Basically, the whole project will be applying a Waterfall Development Model due to its simplicity and requires linear progress. With this report, the basis for the research of this project will be underlined in detail, including the technologies as well the study of recent researches related to the study and also summarizing the result form the surveys that have been done through out t the whole period given . Finally the result of this project, will be in the mobile web application where user can easily access the system through Wi-Fi technology using their mobile phone or their Personal Digital Assistance (PDA

    Toponym Disambiguation in Information Retrieval

    Full text link
    In recent years, geography has acquired a great importance in the context of Information Retrieval (IR) and, in general, of the automated processing of information in text. Mobile devices that are able to surf the web and at the same time inform about their position are now a common reality, together with applications that can exploit this data to provide users with locally customised information, such as directions or advertisements. Therefore, it is important to deal properly with the geographic information that is included in electronic texts. The majority of such kind of information is contained as place names, or toponyms. Toponym ambiguity represents an important issue in Geographical Information Retrieval (GIR), due to the fact that queries are geographically constrained. There has been a struggle to nd speci c geographical IR methods that actually outperform traditional IR techniques. Toponym ambiguity may constitute a relevant factor in the inability of current GIR systems to take advantage from geographical knowledge. Recently, some Ph.D. theses have dealt with Toponym Disambiguation (TD) from di erent perspectives, from the development of resources for the evaluation of Toponym Disambiguation (Leidner (2007)) to the use of TD to improve geographical scope resolution (Andogah (2010)). The Ph.D. thesis presented here introduces a TD method based on WordNet and carries out a detailed study of the relationship of Toponym Disambiguation to some IR applications, such as GIR, Question Answering (QA) and Web retrieval. The work presented in this thesis starts with an introduction to the applications in which TD may result useful, together with an analysis of the ambiguity of toponyms in news collections. It could not be possible to study the ambiguity of toponyms without studying the resources that are used as placename repositories; these resources are the equivalent to language dictionaries, which provide the di erent meanings of a given word.Buscaldi, D.

    The introduction of information and communication technology (ICT) into the classroom has led to a new learning scenario based on educational innovation, in which mobile devices are used for teaching. In this study, the views of upper middle class students in a private educational institution in Mexico on the implementation of augmented reality teaching strategy based on metaverse mobile application are analyzed. The study is descriptive and survey based. Data retrieval is conducted using a clearly designed digital questionnaire. From August to December 2018, 192 first semester students who participated in the basic mathematics course participated in the course. The results show that compared with the previous academic year, the school recognition index has improved, and the affinity for the use of reality in the classroom has improved. When using the strategies mediated by these tools, the view of learning change is favorable. Therefore, it can be inferred that the application of augmented reality in mathematics teaching is of great help to students’ performance

    Reorganizing the relationship of digital library resources and physical learning environments

    Introduction. This preliminary study examines the application of contemporary practice-based approaches to generate data for guiding the design of information literacy learning environments. Method. This study was conducted by interviewing three engineering students who were participating at the Tools for master’s thesis course arranged by Aalto University Library’s Otaniemi Campus Library. The interview’s structure was two-fold, as it first sketched out the participant’s master’s thesis practices through Schatzki’s site ontology and secondly examined the perceived value of different information literacy learning tasks on the latter. Results. The master’s thesis practices of the interviewees were networked in complex ways with e.g. economic life and the interviewees invested much in them. Two of the interviewees worked with their thesis full-time with surroundings and tools provided by their employer. The interviewees valued most the lecture, which comprised of narratives of completed master’s thesis projects and the lecture of scientific writing. From the asynchronous online learning tasks, the interviewees valued most the information retrieval task and the concept map exercise. Conclusion. Spatial library spaces could be provided with asynchronous content such as descriptions of the library services through the tasks of the central user groups and e.g. introductory videos to information retrieval techniques. These contents could be spatially located so that they would serve as facile entrance points to the mobile digital library. The practice-based approaches seem to provide a fertile way of examining student learning and insights gained through them may prove to be valuable in designing new information literacy learning environments.Peer reviewe
