The purpose of this paper is to identify the benefits of an approach in which document management systems (DMSs) are based on a formal and explicit document model, primarily in terms of facilitating domain-specific customization.

Within this paper, a generic document model is proposed. The model consists of two layers. A general purpose layer, which represents common features of the documents, and a domain-specific layer, modeling properties particular to application domain. The general purpose layer is based on ISO 82045, providing high degree of interoperability with other systems developed with respect to this set of standard.

Splitting document model into the layers enables DMSs to be tailored for each particular domain of application, depending on the general purpose layer. The existence of domain-specific layer allows documents to be interpreted differently in different domains of application.

In order to enable customization of DMS for a particular domain, the implementation of domain-specific document layer is required. Also, the proposed model does not explicitly deal with document dynamics.

The proposed document ontology is general enough to provide the representation of documents not depending on a specific scope of application, yet flexible enough to enable extensions through which domain-specific document features can be expressed. The separation of document model enables development of core DMS offering services relying explicitly on the general purpose layer on one hand, as well as domain-specific customization of DMS on the other.

Informally computer scientists reported they could access free copies of research papers they needed via tools such as Google Scholar. To ascertain whether this perception came from widespread free access or from unnoticed employer-paid access, the purpose of this paper was to locate computer science papers and determine what proportion was freely available using Google Scholar.

A sample of 1,967 conference papers and periodical papers from 2003 to 2010, indexed in the ACM Guide to Computing Literature, was searched for manually in Google Scholar, using the paper or article title and the first author's surname and supplementary searches as needed.

Free full-text versions were found for 52 per cent of the conference papers and 55 per cent of the periodical papers. Documents with older publication dates were more likely to be freely accessible than newer documents, with free versions found for 71 per cent of items published in 2003 and 43 per cent of items published in 2010.

Results were limited to the retrieval of known computer science publications via Google Scholar. Future research could examine whether the decline found in this study is specific to Google Scholar or reflects a decrease in the free sharing of research by computer scientists.

Previous research for computer science found lower levels of free access than this research determined, but the decline found in this study runs contrary to increases that have been found. This research confirms many computer science papers are available for free but also that subscription holdings are necessary for complete coverage of papers in the field.

The purpose of this paper is to document Hong Kong University of Science and Technology's (HKUST's) experiences in developing its Institutional Repository and to highlight its programming developments in full‐text linking and indexing, and cross institutional searching.

This paper describes how HKUST Library planned and set up its institutional repository, how it acquired and processed the scholarly output, and what procedures and guidelines were established. It also discusses some new developments in systems, including the implementation of OpenURL linking from the pre‐published version in the repository to the published sources; the partnership with Scirus to enable full‐text searching; and the development of a cross‐searching platform for institutional repositories in Hong Kong.

The paper reveals what and why some policy issues should be adopted, including paper versioning, authority control, and withdrawal of items. It notes what proactive approaches should be adopted to harvest research output. It also shows how programming work can be done to provide usage data, facilitate searching and publicize the repository so that scholarly output can be more accessible to the research community.

The paper provides a very useful case study for other academic libraries who want to develop their own institutional repositories.

HKUST is an early implementer of institutional repositories in Asia and its unique experience in policy issues, harvesting contents, standardization, software customization, and measures adopted in enhancing global access will be useful to similar institutions.

The purpose of this paper is to propose methods for fast incremental indexing with effective and efficient query processing in XML element retrieval. The effectiveness of a search system becomes lower if document updates are not handled when these occur frequently on the Web. The search accuracy is also reduced if drastic changes in document statistics are not managed. However, existing studies of XML element retrieval do not consider document updates, although these studies have attained both effectiveness and efficiency in query processing. Thus, the authors add a function for handling document updates to the existing techniques for XML element retrieval.

Though it will be important to enable fast updates of indices, preliminary experiments have shown that a simple incremental update approach has two problems: some kinds of statistics are inaccurate, and it takes a long time to update indices. Therefore, two methods are proposed: one to approximate term weights accurately with a small number of documents, even for dynamically changing statistics; and the other to eliminate unnecessary update targets.

Experimental results show that this proposed system can update indices up to 32 per cent faster than the simple incremental updates while the search accuracy improved by 4 per cent compared with the simple approach. The proposed methods can also be fast and accurate in query processing, even if document statistics change drastically.

The paper shows that there could be a more practical XML element search engine, which can access the latest XML documents accurately and efficiently.

The Agora project recognises that effective communication is a key to achieving successful project outcomes. One of its objectives is to develop an integrated communications environment for both internal and external communications. Collaborative workspace software to support asynchronous communication is seen as the core application within such an environment. Requirements for such software were developed, together with an evaluation plan. Three collaborative workspace products (Web4Groups, BSCW and AltaVista Forum) that passed preliminary criteria were selected for detailed evaluation. Results showed that BSCW met Agora's needs most closely and the project is currently in the process of implemention.

This paper aims to suggest how the information journey of students with disabilities could be facilitated, by first revealing the existence of inaccessible formats such as Portable Document Format (PDF) and then suggesting the inclusion of alternative formats of accessible learning materials, thus improving retrieval.

A sample of 400 articles published over 10 years (2009-2018) from four journals are selected and analysed for accessibility against the Web Content Accessibility Guidelines WCAG 2.0 by using automated accessibility checkers, a screen reader and manual human expertise. The results are presented and recommendations made on improving accessibility.

The findings suggest that the PDF versions of the selected journal articles are not accessible for screen reader users but could be improved by adopting accessible and inclusive practices. Including alternative formats of the learning materials could help support the student information journey.

The results of the study might not be very representative of all the articles in the journals given the small sample size. Additionally, the criteria used in the study do not consider all existing disabilities. Thus, although the PDFs may be inaccessible for some people with disabilities, they may be accessible to others.

Given that PDFs seem to be the preferred format of journal articles online, there is potential for a difficult information journey for some students due to the limitations posed by inaccessibility of the PDFs. Thus, it is recommended to include alternative formats which could be more accessible, giving the student the choice of accessing the learning materials in their preferred format.

If students are unable to access the learning materials that are required for their course, this could lead to poor grade, which might negatively affect the students’ morale. In some cases, some students might drop out.

This study analyses the accessibility of learning materials provided by a third party (journal publishers) and how they affect the student, something that is not usually given much importance when research in accessibility is carried out.

Electronic reserves help registered campus users who need anytime‐access to documents. Electronic reserves comprise digital files, mostly HTML or PDF formats. In some circumstances the HTML or PDF file is “readable” to the sighted individual, but are sometimes either partially or completely unreadable to the visually impaired using assistive technology. Creating “accessible” PDF files poses more challenges than creating “accessible” HTML files. Several options are suggested to help solve this problem.

Concentrates on the results of the European Commission funded Electronic Document Interchange between Libraries (EDIL) project. Includes details of the work of the Group on Electronic Interchange (GEDI) on which the project is based, together with a brief description of the partners in the project. The results of the project are that, although the technological solution worked well, there were several outstanding operational and market issues that require resolution before such a system can be used commercially. It will also be necessary to resolve the copyright issues surrounding electronic document delivery.

The digitization of electronic document management (EDM) in the construction industry has become more common in nature with the evolution of technology. However, there are still some limitations in EDM in the common data environment which can be improved with the integration of blockchain technology. The purpose of this paper is to identify the limitations of the current EDM system in the construction industry, to determine the potential of blockchain in improving the EDM system in the construction industry and challenges towards blockchain-based EDM.

Semi-structured interviews were conducted with nine (9) respondents with background from the construction industry and blockchain expertise. Content analysis was used to analyze the primary data.

Current EDM system in the construction industry possessed limitations such as system maturity, high cost, slow adoption of technology and security concerns. Blockchain is able to make improvements in the current EDM system in terms of data integrity, data tracking, data immutability, data security, data trustability, and data accountability. Several challenges such as costs, blockchain scalability and industry knowledge, industry culture and hardware need to overcome prior blockchain-based EDM systems can be widely applied in the construction industry.

The research findings provide insight on future EDM in the construction industry and aids future research in this field.

This study aims to extract knowledge of ancient Chinese scientific and technological documents bibliographic summaries (STDBS) and provide the knowledge graph (KG) comprehensively and systematically. By presenting the relationship among content, discipline, and author, this study focuses on providing services for knowledge discovery of ancient Chinese scientific and technological documents.

This study compiles ancient Chinese STDBS and designs a knowledge mining and graph visualization framework. The authors define the summaries' entities, attributes, and relationships for knowledge representation, use deep learning techniques such as BERT-BiLSTM-CRF models and rules for knowledge extraction, unify the representation of entities for knowledge fusion, and use Neo4j and other visualization techniques for KG construction and application. This study presents the generation, distribution, and evolution of ancient Chinese agricultural scientific and technological knowledge in visualization graphs.

The knowledge mining and graph visualization framework is feasible and effective. The BERT-BiLSTM-CRF model has domain adaptability and accuracy. The knowledge generation of ancient Chinese agricultural scientific and technological documents has distinctive time features. The knowledge distribution is uneven and concentrated, mainly concentrated on C1-Planting and cultivation, C2-Silkworm, and C3-Mulberry and water conservancy. The knowledge evolution is apparent, and differentiation and integration coexist.

This study is the first to visually present the knowledge connotation and association of ancient Chinese STDBS. It solves the problems of the lack of in-depth knowledge mining and connotation visualization of ancient Chinese STDBS.
