“…Different software agents and mobile agents will be used in digital libraries to perform different tasks (Madalli, 2003). Semantic Web is introducing semantic search engines and semantic techniques to develop automatic metadata generation to offer effective digital library services (Tönnies and Balke, 2009). Semantic digital libraries will offer a vast amount of information by providing interoperability among heterogeneous information systems.…”

“…Use of Semantic Web in digital libraries will make it possible to re-use these contents. These sources can be searched out from not only a semantic digital library but also other digital information systems available on the web (Tönnies and Balke, 2009). Use of universal resource identifiers (URIs) shall enable the web to search for the exact information and make the information easily accessible and retrievable.…”

Purpose The purpose of this paper is to explore useful Semantic Web technologies and ontology-based applications for digital libraries. It also investigates the perceptions of university librarians and academicians in Pakistan about Semantic Web technologies and their use in digital libraries. Design/methodology/approach An exploratory research design based on Delphi research strategy was conducted to answer the research questions. Interviews were conducted with a purposive sample of 50 key informants including university librarians and academicians to explore their perceptions about Semantic Web technologies and their use in digital libraries. Thematic analysis of interview data was conducted to obtain results. Findings The results of this paper showed that DuraCloud, Semantic information mashup, OntoEdit and resource description framework (RDF) are the various Semantic Web applications which are useful for digital libraries to develop semantic relationships among digital contents and increase their accessibility in the web environment. Findings revealed that Semantic Web provides precise results and meets user information needs in an effective way. Results also showed that next-generation digital libraries use context-awareness technology, intelligent agent software and detecting sensors to analyze user information needs and provide dynamic information services. This paper recommended that librarians should embrace the use of emerging web technologies in libraries and offer library services through the medium of the web. Practical implications This paper envisaged the future of digital library services and Semantic Web applications that can be used to re-structure metadata of digital library. This paper has practical implications for librarians to consider the useful applications of Semantic Web for digital library and enhance the interoperability of metadata among heterogeneous information systems. Practically, results obtained from this paper are highly useful for library schools and LIS teachers to up-date their curriculum by incorporating new contents related to web languages and Semantic Web applications for digital libraries. Originality/value This paper identifies various Semantic Web applications which are useful for developing Semantic Digital Libraries.

“…We conducted a user study with domain experts, in our case practitioners in the field of organic chemistry, for evaluating the three metrics DCC, SWD and RCT defined in [1]. The aim of the study was first to get a feeling whether the defined metrics are useful and second how important the information provided is compared to classical forms of visualization.…”

Abstract. Today, digital libraries more and more have to rely on semantic techniques during the workflows of metadata generation, search and navigational access. But, due to the statistical and/or collaborative nature of such techniques, the underlying quality of automatically generated metadata is questionable. Since data quality is essential in digital libraries, we present a user study on one hand evaluating metrics for quality assessment, on the other hand evaluating their benefit for the individual user during interaction. To observe the interaction of domain experts in the sample field of chemistry, we transferred the abstract metrics' outcome for a sample semantic technique into three different kinds of visualizations and asked the experts to evaluate these visualizations first without, later augmented with the quality information. We show that the generated quality information is indeed not only essential for data quality assurance in the curation step of digital libraries, but will also be helpful for designing intuitive interaction interfaces for end-users. Keywords: Digital Libraries, Information Quality, Semantic Technologies IntroductionDigital Libraries have to handle a vast amount of data ranging from individual papers or reports in journals, conference proceedings etc. up to complete digitized books. Making such data searchable relies mainly on the amount and quality of the provided metadata. On a purely bibliographic level this metadata is relatively easy to derive and maintain, in contrast on the content level the problem of deriving correct metadata obviously grows with the density of information. Whereas the information contained in short conference papers can be manually extracted and annotated quite easily, capturing the content contained in a book definitely needs automatic means of extraction. Today semantic techniques relying on statistically approaches like term co-occurrences or frequencies are already commonplace. But the quality of metadata derived by such techniques is largely uninvestigated. Thus a main topic of future digital library research has to be a quality assessment of such techniques. Obviously the quality -like in information retrievals' precision / recall analysis -can only be evaluated comparing the techniques output with manually provided judgments.
