Purpose: This study is a user evaluation on the usability of the Mogao Cave Panorama Digital Library(DL), aiming to measure its effectiveness from the users' perspective and to propose suggestions for improvement. Design/methodology/approach: Usability tests were conducted based on a framework of evaluation criteria and a set of information seeking tasks designed for the Dunhuang cultural heritage, and interviews were conducted for soliciting in-depth opinions from participants. Findings: The results of the usability tests indicate that the DL was more efficient in supporting simple information seeking tasks than those of higher-complexity levels. Statistical tests reveal that there were correlations among dimensions of usability criteria and user effectiveness measures. Moreover, interview discourses exposed specific usability issues of the DL. Research limitations: This research is based on a relatively small sample size, resulting in a limited representativeness of user diversity. A larger sample size is needed for a systematic cross group comparison.Practical implications: This study evaluated the usability of the Mogao Cave Panorama DL and proposed suggestions for its improvement for better experience. The results also provide a reference to other cultural heritage DLs with panorama functions. Originality/value: This study is one of the first evaluating cultural heritage DLs from the perspective of user experience. It provides methodological references for relevant studies: the evaluation framework, the designed information seeking tasks, and the interview questions can be adopted or adapted in evaluating other visually centric DLs of cultural heritage. 展开更多

The volume of information being created, generated and stored is huge. 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

In a very large digital library that support computer aided collaborative design, an indexing process is crucial whenever the retrieval process has to select among many possible designs. In this paper, we address the problem of retrieving important design and engineering information by structural indexing. A design is represented by a model dependency graph, therefor, the indexing problem is to determine whether a graph is present or absent in a database of model dependency graphs. we present a novel graph indexing method using polynomial characterization of a model dependency graph and on hashing. Such an approach is able to create an high efficient 3D solid digital library for retrieving and extracting solid geometric model and engineering information. 展开更多

Digital libraries are complex systems and this brings difficulties for their evaluation.This paper proposes a hierarchical model to solve this problem,and puts the entangled matters into a clear-layered structure.Firstly,digital libraries(DLs thereafter)are classified into 5 groups in ascending gradations,i.e.mini DLs,small DLs,medium DLs,large DLs,and huge DLs by their scope of operation.Then,according to the characteristics of DLs at different operational scope and level of sophistication,they are further grouped into unitary DLs,union DLs and hybrid DLs accordingly.Based on this simulated structure,a hierarchical model for digital library evaluation is introduced,which evaluates DLs differentiatingly within a hierarchical scheme by using varying criteria based on their specific level of operational complexity such as at the micro-level,medium-level,and/or at the macro-level.Based on our careful examination and analysis of the current literature about DL evaluation system,an experiment is conducted by using the DL evaluation model along with its criteria for unitary DLs at micro-level.The main contents resulting from this evaluation experimentation and also those evaluation indicators and relevant issues of major concerns for DLs at medium-level and macro-level are also to be presented at some length. 展开更多

The objective of Universal Digital Library (UDL) is to capture all books in digital format. A text to speech (TTS) interface for UDL portal would enable access to the digital content in voice mode, and also provide access to the digital content for illiterate and vision-impaired people. Our work focuses on design and implementation of text to speech interface for UDL portal primarily for Indian languages. This paper is aimed at identifying the issues involved in integrating text to speech system into UDL portal and describes the development process of Hindi, Telugu and Tamil voices under Festvox framework using unit selection techniques. We demonstrate the quality of the Tamil and Telugu voices and lay out the plan for integrating the TTS into the UDL portal. 展开更多

It represents an “extension” from a traditional library. The core and essence is to build a favorable surroundings for knowledge accumulation, knowledge transfer and knowledge communication. Management communication covers information transfer and organization cooperation. Compared with traditional library, the management communication in digital library shoulders the commitment to support knowledge innovation. On the basis of analysis of the connotation of digital library, this paper analysed the aspects of management communication, including communicators, communication styles, contents, channels and outer communication, all of which tries to construct an integrated model of management communication in a digital library and turns a library into an actual “knowledge fountain”. 展开更多

Information seekers are generally on their own to discover and use a research library’s growing array of digital col- lections, and coordination of these collections’ development and maintenance is often not optimal. The frequent lack of a con- scious design for how collections fit together is of equal concern because it means that research libraries are not making the most of the substantial investments they are making in digital initiatives. This paper proposes a framework for a research library’s digital collections that offers integrated discovery and a set of best practices to underpin collection building, federated access, and sus- tainability. The framework’s purpose is to give information seekers a powerful and easy way to search across existing and future collections and to retrieve integrated sets of results. The paper and its recommendations are based upon research undertaken by the author and a team of librarians and technologists at Cornell University Library. The team conducted structured interviews of forty-five library staff members involved in digital collection building at Cornell, studied an inventory of the library’s more than fifty digital collections, and evaluated seven existing Open Archives Initiative (OAI) and federated search production or prototype systems. The author will discuss her team’s research and the rationale for their recommendations to: present a cohesive view of the library’s digital collections for both browsing and searching at the object level; take a programmatic (rather than project-based) approach to digital collection building; require that all new digital collections conform to library-developed and agreed-upon OAI best practices for data providers; and implement organizational structures to sustain the library’s digital collections over the long term. 展开更多

Few of the current approaches to achieve the integration of digital library system have considered the influence of network factors on quality of service for the integration system of digital libraries. For this reason, a mobile agent based framework for integrating digital library system is proposed. Based on this framework, a prototype system is implemented and the key technique for it are described. Compared with the current approaches, using mobile agent technique to achieve the integration of digital library system can not only avoid transmitting a lot of data on the network, lower the dependence on network bandwidth for the system, but also improve the quality of service for the integration system of digital libraries in intermitted or unreliable network connection settings. 展开更多

The China-US Million Book Digital Library Project (Million Book Project) is an international cooperation program between China and the US. 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 or- ganization and services. In this keynote speech, we simply review our work in these areas, and argue that by technological co- operation with these innovation research topics, the project will develop a top-level digital library platform for the million book library. 展开更多
