- Abstract
- The nature and implications of electrocopying are summarised. After a brief review of the principles of copyright, the issue of whether electrocopying infringes copyright is debated. Publishers are aware of the threat that electrocopying poses to their business. The various options available to publishers for responding to electrocopying are summarised. Patterns of scholarly communications and the relationships between authors, publishers and libraries are being challenged. Constructive dialogue is necessary if the issues are to be resolved

- Abstract
- Internet based electronic resources are growing dramatically but there have been no empirical studies evaluating the impact of e-sources, as a whole, on formal scholarly communication. reports results of an investigation into how much e-sources have been used in formal scholarly communication, using a case study in the area of Library and Information Science (LIS) during the period 1994 to 1996. 4 citation based indicators were used in the study of the impact measurement. Concludes that, compared with the impact of print sources, the impact of e-sources on formal scholarly communication in LIS is small, as measured by e-sources cited, and does not increase significantly by year even though there is observable growth of these impact across the years. It is found that periodical format is related to the rate of citing e-sources, articles are more likely to cite e-sources than are print priodical articles. However, once authors cite electronic resource, there is no significant difference in the number of references per article by periodical format or by year. Suggests that, at this stage, citing e-sources may depend on authors rather than the periodical format in which authors choose to publish

- Abstract
- We present CopeOpi, an opinion-analysis system, which extracts from the Web opinions about specific targets, summarizes the polarity and strength of these opinions, and tracks opinion variations over time. Objects that yield similar opinion tendencies over a certain time period may be correlated due to the latent causal events. CopeOpi discovers relationships among objects based on their opinion-tracking plots and collocations. Event bursts are detected from the tracking plots, and the strength of opinion relationships is determined by the coverage of these plots. To evaluate opinion mining, we use the NTCIR corpus annotated with opinion information at sentence and document levels. CopeOpi achieves sentence- and document-level f-measures of 62% and 74%. For relationship discovery, we collected 1.3M economics-related documents from 93 Web sources over 22 months, and analyzed collocation-based, opinion-based, and hybrid models. We consider as correlated company pairs that demonstrate similar stock-price variations, and selected these as the gold standard for evaluation. Results show that opinion-based and collocation-based models complement each other, and that integrated models perform the best. The top 25, 50, and 100 pairs discovered achieve precision rates of 1, 0.92, and 0.79, respectively.

- Abstract
- Richer graph models permit authors to 'program' the browsing behaviour they want WWW readers to see by turning the hypertext into a hyperprogram with specific semantics. Multiple browsing streams can be started under the author's control and then kept in step through the synchronization mechanisms provided by the graph model. Adds a Semantic Web Graph Layer (SWGL) which allows dynamic interpretation of link and node structures according to graph models. Details the SWGL and its architecture, some sample protocol implementations, and the latest extensions to MHTML

- Abstract
- Discusses the publishing of books online on the Internet, in the USA. The issues is treated mainly in relation to trade publishers. Outlines various ways in which such publishers have so far used the Internet, for example in the publishing of the full text of works of fiction, for publishing catalogues, and for presenting authors to the public via bulletin boards or electronic conferences. Notes a number or problems which arise: copyright, payment for accessing items, advertising restrictions, and the ease with which the published unit can be tampered with when available on the Internet. Also discusses collaboration and conflicts between publishers and the technology industry

- Abstract
- Technological developments have changed the concepts of publication, reproduction and distribution. However, legislation, and in particular the Legal Deposit Law has not adjusted to these changes - it is very restrictive in the sense of protecting the rights of authors of electronic publications. National libraries and national archival institutions, being aware of their important role in preserving the written and spoken cultural heritage, try to find different legal ways to live up to these responsibilities. This paper presents some legal aspects of archiving Web pages, examines the harvesting of Web pages, provision of public access to pages, and their long-term preservation.
