Innovative Evaluation System – IESM: An Architecture for the Database Management System for Mobile Application

As the mobile applications are constantly facing a rapid development in the recent years especially in the academic environment such as student response system [1-8] used in universities and other educational institutions; there has not been reported an effective and scalable Database Management System to support fast and reliable data storage and retrieval. This paper presents Database Management Architecture for an Innovative Evaluation System based on Mobile Learning Applications. The need for a relatively stable, independent and extensible data model for faster data storage and retrieval is analyzed and investigated. It concludes by emphasizing further investigation for high throughput so as to support multimedia data such as video clips, images and documents

Highly focused document retrieval in aerospace engineering : user interaction design and evaluation

Purpose – This paper seeks to describe the preliminary studies (on both users and data), the design and evaluation of the K-Search system for searching legacy documents in aerospace engineering. Real-world reports of jet engine maintenance challenge the current indexing practice, while real users’ tasks require retrieving the information in the proper context. K-Search is currently in use in Rolls-Royce plc and has evolved to include other tools for knowledge capture and management. Design/methodology/approach – Semantic Web techniques have been used to automatically extract information from the reports while maintaining the original context, allowing a more focused retrieval than with more traditional techniques. The paper combines semantic search with classical information retrieval to increase search effectiveness. An innovative user interface has been designed to take advantage of this hybrid search technique. The interface is designed to allow a flexible and personal approach to searching legacy data. Findings – The user evaluation showed that the system is effective and well received by users. It also shows that different people look at the same data in different ways and make different use of the same system depending on their individual needs, influenced by their job profile and personal attitude. Research limitations/implications – This study focuses on a specific case of an enterprise working in aerospace engineering. Although the findings are likely to be shared with other engineering domains (e.g. mechanical, electronic), the study does not expand the evaluation to different settings. Originality/value – The study shows how real context of use can provide new and unexpected challenges to researchers and how effective solutions can then be adopted and used in organizations.</p

What-if analysis: A visual analytics approach to Information Retrieval evaluation

This paper focuses on the innovative visual analytics approach realized by the Visual Analytics Tool for Experimental Evaluation (VATE2) system, which eases and makes more effective the experimental evaluation process by introducing the what-if analysis. The what-if analysis is aimed at estimating the possible effects of a modification to an Information Retrieval (IR) system, in order to select the most promising fixes before implementing them, thus saving a considerable amount of effort. VATE2 builds on an analytical framework which models the behavior of the systems in order to make estimations, and integrates this analytical framework into a visual part which, via proper interaction and animations, receives input and provides feedback to the user. We conducted an experimental evaluation to assess the numerical performances of the analytical model and a validation of the visual analytics prototype with domain experts. Both the numerical evaluation and the user validation have shown that VATE2 is effective, innovative, and useful

Pioneer brand advantage with UK consumers

Telah dilakukan kegiatan Lesson Study (LS) dalam rangka pengembangan kompetensi pendidik bidang biologi di perguruan tinggi untuk agar mengembangkan dan mengimplementasikan pembelajaran biologi yang berorientasi pada character building sekaligus meningkatkan kualitas pembelajaran. Secara spesifik, fokus pencapaian kegiatan LS ini adalah: 1) pengembangan kemampuan dosen biologi dalam mengembangan dan mengimplementasikan pembelajaran biologi umum dengan socioscientific issues-based instruction secara kolegial dalam tim LS, dan 2) menumbuhkembangkan karakter peduli dan reflective judgement mahasiswa pendidikan kimia dalam konteks ilmu biologi umum. Prosedur pelaksanaan LS ini mengikuti tahap-tahap plan-do-see, yang dilaksanakan sebanyak tiga putaran. Instrumen yang digunakan meliputi: 1) perangkat pembelajaran biologi umum berbasis socioscientific issues, 2) lembar pengamatan aktivitas dosen, 3) lembar pengamatan aktivitas belajar mahasiswa, dan 4) lembar penilaian reflective judgment. Data yang diperoleh dianalisis secara deskriptif. Hasil kegiatan LS menunjukkan adanya dinamika, tantangan dan hambatan yang dialami baik oleh dosen model maupun subjek mahasiswa

CHORUS Deliverable 2.2: Second report - identification of multi-disciplinary key issues for gap analysis toward EU multimedia search engines roadmap

After addressing the state-of-the-art during the first year of Chorus and establishing the existing landscape in multimedia search engines, we have identified and analyzed gaps within European research effort during our second year. In this period we focused on three directions, notably technological issues, user-centred issues and use-cases and socio- economic and legal aspects. These were assessed by two central studies: firstly, a concerted vision of functional breakdown of generic multimedia search engine, and secondly, a representative use-cases descriptions with the related discussion on requirement for technological challenges. Both studies have been carried out in cooperation and consultation with the community at large through EC concertation meetings (multimedia search engines cluster), several meetings with our Think-Tank, presentations in international conferences, and surveys addressed to EU projects coordinators as well as National initiatives coordinators. Based on the obtained feedback we identified two types of gaps, namely core technological gaps that involve research challenges, and “enablers”, which are not necessarily technical research challenges, but have impact on innovation progress. New socio-economic trends are presented as well as emerging legal challenges

Managing knowledge management tools: a systematic classification and comparison

Knowledge management (KM) is playing an important role in commercial and academic activities, and people are usually armed with effective KM tools for implementation. On one hand, KM tools can facilitate KM activities; however, on the other hand, with the “explosion” of KM tools development, people may feel confused about which to choose or which is more suitable. As a result, KM tools should be managed, so this paper aims at making a systematic classification and comparison research and proposes a KM tools selection strategy based on a point of view on knowledge lifecycle
