In this paper we introduce a system that collects English-Japanese translation document pairs from the Web that are relevant to subject keywords specified by the user. The system, QRselect, is specifically designed to meet the needs of online volunteer translators who, in the process of translation, want to refer to a small and specific set of translation document pairs which are relevant to what they are translating. A system which collects relevant existing translated documents and makes them available for reference in the translation process will therefore greatly help these translators. Against this backdrop, we developed a prototype translated document collection system and evaluated its performance. We also examined the users’ role in improving the system.

Digitizing ancient books, especially those related to the humanities, is practiced in many countries. The number of full-text databases in the humanities is increasing. Studies have shown that ancient books are important resources for humanities scholars and researchers. However, comparatively little research has been done concerning the use of those databases. Thirty graduate students majoring in Chinese Literature or History were interviewed in this study. This study attempts to answer the following questions: How do interviewees use the databases? Do they encounter any problems? What do they have to say concerning ancient books in digital or paper form? The results show that humanities graduate students use ancient books databases to locate information concerning their research interests. Most of them are satisfied with the search functions and feel that the databases are convenient to use. However, they comment that the coverage, quality, and search interface could be improved upon. As well, a few graduate students suggest that links to related resources should be added. They state that they do not totally rely upon the databases and continue to use paper sources.

The increasing number of users and the diffusion of has increased the demand for newer and improved systems to give better assistance to the user during the search of resources in collections managed by (). In this perspective, the annotations made on documents offer an interesting possibility for improving both the user experience of the DLS and the retrieval performance of the system itself. However, while different approaches based on annotations have been proposed, they still lack a full experimental evaluation, mainly because an experimental collection with annotation is missing. Therefore, this paper addresses the problem of setting an adequate experimental test-bed for DL search algorithms which exploit annotations, and discusses a flexible strategy for creating test collections with annotated documents.

Fair use is a difficult problem to implement in DRM systems due to its vagueness and uncertainty. We propose a fair use mechanism based on without limitation, and , which brings a fair use mechanism nearer to offline world than that of existing DRM systems.

In this paper, we propose an ontology-based metadata integration methodology for the cultural heritage domain. The proposed real - world approach considers an integration architecture in which CIDOC/CRM ontology acts as a mediating scheme. In this context, we present a mapping methodology from Encoded Archival Description (EAD) and Dublin Core (DC) metadata to CIDOC/CRM, and discuss the faced difficulties.

The purpose of this paper is to raise arguments to support the proposal that we should promote the discussion of the Digital Library in a structured way, aligned with the emerging perspective of the Enterprise Architecture. In this sense, the Digital Library practitioners should be motivated to give more emphasis to the need to better integrate its efforts and body of knowledge with the more generic area of Information Systems, where important concepts, regulations and good practices have been emerging, defined by authorities, the industry and the multiple stockholders of each specific scenario. Concluding, it is time for the Digital Library to mature by recognizing that it is, simply, a case of an Information System, which is specific only in what concerns the requirements derived of its specific business goals.

The paper presents a multimedia database model accounting for the representation of documents, collections and the associated metadata. Appropriate structures are provided for descriptive metadata and for metadata resulting from automatic content analysis. The model is based on the identification and unification of the main concepts in the archival standards and the audiovisual area.

The main features of the model, designed to support multimedia database applications, are the integration of descriptive and content analysis metadata, the association of metadata to collections as well as to items, the extensibility with respect to the inclusion of new descriptors and the support to several retrieval modes. The MetaMedia application development platform, based on the model, has been used to support the construction of a historic documentation collection where a common web interface provides collection administrators, metadata creators and visitors a multi-faceted view of the repository.

We propose in this paper to integrate the semantic description of the image and the relational characterization of its components through an architecture which follows a sharp process for generating image index and query representations and computing their correspondence. This architecture relies on an expressive representation formalism handling high-level image descriptions and a conceptual query framework in an attempt to operate image indexing and retrieval operations beyond keyword-based and loosely-coupled state-of-the-art systems. At the experimental level, we evaluate its retrieval performance through recall and precision indicators on a test collection of 2500 color photographs.

In this paper, we discuss current issues and future trends on intellectual properties of digital libraries by interpreting legal concepts in engineering manner as a reference to Asia-Pacific DL researchers and practitioners. First, we discuss problems on copyright entities in digital libraries and patent objects in their retrieval mechanisms. Second, we formulate the conditions of copyrightability on the multimedia databases as digital libraries and the patentability on the parameter setting components in retrieval mechanisms. Third, we discuss a new direction for protecting numerical parametric information as trade secret embedded in the patentable parameter setting components.

Video and text-news content have recently been broadcast on TV, newspapers, and the Internet. Although video content on out-of-date news is of little value for viewing, it can be considered to have value by comparing it to related content. Repeated news should especially be compared, e.g., the Olympic games and international expositions. We propose a method of retrieving comparison content based on the order of news elements. It is composed of two parts. The first is an analysis of news content that someone is browsing. The second is the automatic generation of queries for retrieving content on comparison news.
