Application of Ranganathan's Laws to the WebThis paper analyzes the Web and raises a significant question: "Does the Web save the time of the users?" This question is analyzed in the context of Five Laws of the Web. What do these laws mean? The laws are meant to be elemental, to convey a deep understanding and capture the essential meaning of the World Wide Web. These laws may seem simplistic, but in fact they express a simple, crystal-clear vision of what the Web ought to be. Moreover, we intend to echo the simplicity of Ranganathan's Five Laws of Library Science which inspired them.
Linked-OWL: A new approach for dynamic linked data service workflow compositionThe shift from Web of Document into Web of Data based on Linked Data principles defined by Tim Berners-Lee posed a big challenge to build and develop applications to work in Web of Data environment. There are several attempts to build service and application models for Linked Data Cloud. In this paper, we propose a new service model for linked data "Linked-OWL" which is based on RESTful services and OWL-S and copes with linked data principles. This new model shifts the service concept from functions into linked data things and opens the road for Linked Oriented Architecture (LOA) and Web of Services as part and on top of Web of Data. This model also provides high level of dynamic service composition capabilities for more accurate dynamic composition and execution of complex business processes in Web of Data environment.
Structure and form of folksonomy tags: The road to the public library catalogueFolksonomies have the potential to add much value to public library catalogues by enabling clients to: store, maintain, and organize items of interest in the catalogue using their own tags. The purpose of this paper is to examine how the tags that constitute folksonomies are structured. Tags were acquired over a thirty-day period from the daily tag logs of three folksonomy sites, Del.icio.us, Furl, and Technorati. The tags were evaluated against section 6 (choice and form of terms) of the National Information Standards Organization (NISO) guidelines for the construction of controlled vocabularies. This evaluation revealed that the folksonomy tags correspond closely to the NISO guidelines that pertain to the types of concepts expressed by the tags, the predominance of single tags, the predominance of nouns, and the use of recognized spelling. Potential problem areas in the structure of the tags pertain to the inconsistent use of the singular and plural form of count nouns, and the incidence of ambiguous tags in the form of homographs and unqualified abbreviations or acronyms. Should library catalogues decide to incorporate folksonomies, they could provide clear guidelines to address these noted weaknesses, as well as links to external dictionaries and references sources such as Wikipedia to help clients disambiguate homographs and to determine if the full or abbreviated forms of tags would be preferable.
Web impact factors for Iranian UniversitiesThis study investigates the Web Impact Factors (WIFs) for Iranian universities and introduces a new system of measurement. Counts of links to the web sites of Iranian universities were calculated from the output of AltaVista search engine. The WIFs for Iranian universities were calculated by dividing link page counts by the number of pages found in AltaVista for each university at a given point in time. These WIFs were then compared, to study the impact, visibility, and influence of Iranian university web sites. Overall, Iranian university web sites have a low inlink WIF. While specific features of sites may affect an institution's Web Impact Factor, there is a significant correlation between the proportion of English-language pages at an institution's site and the institution's backlink counts. This indicates that for linguistic reasons, Iranian (Persian-language) web sites may not attract the attention they deserve from the World Wide Web. This raises the possibility that information may be ignored due to linguistic and geographic barriers, and this should be taken into account in the development of the global Web.
