Google Scholar (http://scholar.google.com) provides a new method of locating potentially relevant articles on a given subject by identifying subsequent articles that cite a previously published article. An important feature of Google Scholar is that researchers can use it to trace interconnections among authors citing articles on the same topic and to determine the frequency with which others c...

In our study we analysed 3.889 records which were indexed in the Library and Information Science Abstracts (LISA) database in the research field of informetrics. We can show the core journals of the field via a Bradford (power law) distribution and corroborate on the basis of the restricted LISA data set that it was the appropriate time to found a new specialized journal dedicated to informetri...

The aim of this paper is to introduce and assess three algorithms for the identification of overlapping thematic structures in networks of papers. We implemented three recently proposed approaches to the identification of overlapping and hierarchical substructures in graphs and applied the corresponding algorithms to a network of 492 information-science papers coupled via their cited sources. T...

The geopolitical zone known as MENA (Middle East and North Africa), occupying so many newspaper front pages last year owing to the " Arab spring " in Tunisia, Egypt, Libya and Syria, is at the same time largely ignored by the realm of webometrics, scientometrics, and information visualization. The MENA zone would include all 22 countries whose official language is Arabic, and which also belong ...

Structured Abstract. Purpose: The paper suggests an alternative to the widely used Times Cited criterion for analysing citation networks. The approach involves taking account of the natures of the papers that cite a given paper, so as to differentiate between papers that attract the same number of citations. Method: ArticleRank is an algorithm that has been derived from Google's PageRank algori...

One of the determining factors of the quality of Web search engines is the size of their index. In addition to its influence on search result quality, the size of the indexed Web can also tell us something about which parts of the WWW are directly accessible to the everyday user. We propose a novel method of estimating the size of a Web search engine’s index by extrapolating from document frequ...

Purpose – The purpose of this article is to analyze the link-based web site impact measure known as the web impact factor (WIF). It is a quantitative tool for evaluating and ranking web sites, top-level domains and sub-domains. The paper also aims to discuss the WIF’s advantages and disadvantages, data collection problems, and validity and reliability of WIF results. Design/methodology/approach...
