Webometry

from Wikipedia, the free encyclopedia

The webometrics ( Engl. "Webometrics") is a research direction with the help of measurements , the World Wide Web investigated.

History & goals

Webometric research has been around since the mid-1990s. Among other things, it examines the number and links of websites , the resulting structures and the behavior of Internet users .

When extracting information from the World Wide Web, webometry makes use of data mining and graph theory . Search engines or web crawlers are mostly used to collect data. Among other things, the following are evaluated:

  1. The content and properties of websites and other online offers (including methods of linguistics or computational linguistics )
  2. The linking of the pages to one another or the resulting network structure
  3. The behavior of Internet users, for example when browsing, searching and writing

The aim is on the one hand to acquire knowledge about the structure and development of the World Wide Web or parts of it and on the other hand to better find information on the web by using information retrieval with measurements.

Examples of information obtained through webometry are information about the growth and size of the World Wide Web, as well as methods with which relationships between different pages can be determined or with which the popularity of a page can be determined (see for example the PageRank algorithm the search engine Google ).

Webometry is closely related to informetrics , bibliometrics , scientometrics , and web mining . When examining websites and hyperlinks, there are parallels to examining journal articles and citations in bibliometrics. To build on this, Ronald Rousseau coined the term sitation for web links . However, the web is also fundamentally different from other media. Due to updates, it is difficult to determine when a website will be published.

Unlike the webometrics the term Cybermetrie ( Engl. "Cyber metrics"), the quantitative analysis of all Internet services. In addition to the World Wide Web, it also includes e-mail , newsgroups, etc.

scientist

According to a study by Olle Persson, based on 1178 articles from ten journals of library and information science , for the period from 2000 to 2002, the following scientists in the field of webometry were most frequently cited together:

Lennart Björneborn , Blaise Cronin , Leo Egghe , Peter Ingwersen , Ronald Rousseau , Alastair Smith , Mike Thelwall , Liwen Vaughan

All of them are also on the editorial board of Cybermetrics magazine , founded by Isidro Aguillo .

Others: Judit Bar-Ilan , Hildrun Kretschmer
