Quantitative evaluation of scientific publications using statistical methods

Licensed Publication Database

Scopus

Scopus is a multidisciplinary abstract and citation database for research literature and high-quality Internet sources (peer-reviewed).

Various tools are also available for tracking, analyzing, and visualizing research information from various subject areas, such as:

  • Natural sciences, technology, medicine, and health sciences
  • Social sciences
  • Arts and humanities

Scopus also provides citations of scientific articles (references and citations), which enable citation analysis (Who cites whom? Who is cited by whom?).

The evaluation covers publications from 1969 onwards.

The University of Stuttgart Library has licensed Scopus.

University Bibliography

The University Bibliography offers an overview that is as complete as possible of the publications that have been or are being published at the University of Stuttgart. Starting with the year 2015, it shows all publications of all scientific members (according to sec. 9 of the LGH (DE)) which have been written or published, made public or permanently accessible during and, if applicable, after their affiliation with the University. The University Bibliography is maintained via the publication management tool PUMA. Members of the University of Stuttgart can report their publications independently via the PUMA platform. The University Bibliography processes the records and publishes the processed publication metadata in PUMA.

Google Scholar

In 2004, Google launched the beta version of a new search service specifically meant for scientific research. Google Scholar searches numerous scientific servers. The focus is on specialist journals, full texts of paid documents from commercial providers, of which the user can only see an abstract without access authorization, are also indexed. In 2011, Google has added the „Google Scholar Citations“ service. Using it, scientists can create a personal profile. In addition, the widely used h-index and the i10-index are calculated.
