This paper highlights that the use of information technology provides higher efficiency for the performance of daily work in the municipality, thus also the provision of better services to citizens. However, the level of use of information technology in the Municipality of Ferizaj leaves much to be desired in terms of efficiency because a significant number of employees have not attended adequate training for the effective and efficient use of various IT applications and have not are still adapted to the digital environment in the municipality. Therefore, the recommendation derived from this paper is that the information technology environment in the municipality of Ferizaj needs to be improved by providing staff with adequate qualifications, while for those who are currently engaged in the municipality and who do not have adequate qualifications, training should be provided in a way that all users of IT applications are fully integrated into the digitized environment in order to be effective and efficient in providing services to citizens. This simultaneously gives the municipal staff job security and motivation for better services for citizens. Also, information technology enables a better control over the activity of the municipality because every action is recorded as data which can then be used to analyze the performance of the municipality.展开更多

Without adequate knowledge of Information Retrieval (IR) methods, the retrieval process for information would be cumbersome and frustrating. Studies have further revealed that IR methods are essential in information centres (for example, Digital Library environment) for storage and retrieval of information. Therefore, with more than one billion people accessing the Internet, and millions of queries being issued on a daily basis, modern Web search engines are facing a problem of daunting scale. The main problem associated with the existing search engines is how to avoid irrelevant information retrieval and to retrieve the relevant ones. In this study, the existing system of library retrieval was studied. Problems associated with them were analyzed in order to address this problem. The concept of existing information retrieval models was studied, and the knowledge gained was used to design a digital library information retrieval system. It was successfully implemented using a real life data. The need for a continuous evaluation of the IR methods for effective and efficient full text retrieval system was recommended.展开更多

However, one million digitized books are considered not to be the ultimate goal of the project, but a first step towards universal access to human knowledge. In particular, there are four challenges about the new way to analyze, process, operate, visualize and interact with digital media resource in this library. To tackle these challenges, North China Centre of Million Book Project (in Chinese Academy of Sciences) has initiated several innovative research projects in areas such as multimedia content analysis and retrieval, bilingual services, multimodal information presentation, and knowledge-based organization and services. In this keynote speech, we simply review our work in these areas, and argue that by technological cooperation with these innovation research topics, the project will develop a top-level digital library platform for the million book library.展开更多

Usual...Digital Elevation Models (DEMs) are constructed using altitude point data and various interpolation techniques. The quality and accuracy of DEMs depend on data point density and the interpolation technique used. Usually however, altitude point data especially in plain areas do not provide realistic DEMs, mainly due to errors produced as a result of the interpolation technique, resulting in imprecise topographic representation of the landscape. Such inconsistencies, which are mainly in the form of surface depressions, are especially crucial when DEMs are used as input to hydrologic modeling for impact studies, as they have a negative impact on the model’s performance. This study presents a Geographical Information System (GIS) tool, named LAN (Line Attribute Network), for the improvement of DEM construction techniques and their spatial accuracy, using drainage network attributes. The developed tool does not alter the interpolation technique, but provides higher point density in areas where most DEM problems occur, such as lowland areas or places where artificial topographic features exist. Application of the LAN tool in two test sites showed that it provides considerable DEM improvement.展开更多

Through literature review and historical research, the authors argue that the evaluation of the digital library(DL) is still in a research stage and not yet of value to the real achievement of the DL in operation. Because of the variety of the understandings of the digital library and the complexity of the technical factors, we can put forward a set of reference models, measurements and approaches to combine with the various researches on the evaluation theory and practice in the digital library area. The authors primarily discuss and conclude with a digital library evaluation model and measurement index system according to the requirements of the world metropolitan libraries.展开更多

The respective weight of each specific criterion is decided through the Analytic Hierarchy Process(AHP) Method. The findings of this study indicate that, when assigning weights to the selection criteria, it is important to consult the opinions of a wide crosssection of people, especially the views of different users. As a result, the digital resource selection system characterized by the criteria weights can reflect more comprehensively the users' requirements, and meanwhile it enables librarians' more rational selection of digital resources.展开更多

Designing an appropriate information visualization system may be very useful technique for scholars, who intent to get scientific information from digital libraries. The objective of current study was to map and visualize the key-information of dissertations in academic libraries. To achieve the aim, an information retrieval system was designed to present the interactive graphic view of dissertations’ subjects in academic. Methods: An information retrieval system was designed by information visualization toolkit that presents the related subjects of dissertations in academic libraries. In addition, the satisfaction-levels of library-users were analyzed by administrating a standard questionnaire (QUIS Questionnaire). Results: The study indicated that the designed IR system helped to provide a user-friendly environment through displaying subjective relations of dissertations, overwhelming variety of colors in displaying information. Fast and easy access to the cover-to-cover information of dissertations and user-interaction facilities are the advantages of designed IR. Analysis of data furthermore indicated that the users’ satisfaction from the system was from medium to high grade. Conclusion: Designing the IR-system revealed an excessive influence on users’ satisfaction;therefore, proposing such systems for employing in academic libraries is very suitable and its implementation is necessary.展开更多

Based on the basic administrative sections in the information resource lifecycle(IRL), the framework for basic administrative metadata(FBAM) is helpful in constructing open interoperable platforms for acquisition, processing and services of information resources in digital libraries. It facilitates the seamless communication, the cooperative construction and management, and the sharing of digital resources.The formulation of FBAM follows the principles of modularity and openness that promote interoperability in resource management. It also adopts the structured methodology of information system design, with which the FBAM data model is developed in conformity with <indecs> and PREMIS. The capabilities of FBAM are driven by a metadata repository with administrative information that is contained in FBAM records.展开更多
