ABSTRACT: Medical Subject Headings (MeSH) are used to index the
majority of databases generated by the National Library of Medicine.
Essentially, MeSH terms are designed to make information, such as scientific articles, more retrievable and assessable to users of systems such as PubMed. This paper proposes a novel method for automating the assignment of biomedical publications with MeSH terms that takes advantage of citation references to these publications. Our findings show that analysing the citation references that point to a document can provide a useful source of terms that are not present in the document.
The use of these citation contexts, as they are known, can thus help to provide a richer document feature representation, which in turn can help improve text mining and information retrieval applications, in our case MeSH term classification. In this paper, we also explore new methods of selecting and utilising citation contexts. In particular, we assess the effect of weighting the importance of citation terms (found in the citation contexts) according to two aspects: (i) the section of the paper they appear in and (ii) their distance to the citation marker.
We conduct intrinsic and extrinsic evaluations of citation term quality.
For the intrinsic evaluation, we rely on the UMLS Metathesaurus conceptual database to explore the semantic characteristics of the mined citation terms. We also analyse the "informativeness" of these terms using a class-entropy measure. For the extrinsic evaluation, we run a series of automatic document classification experiments over MeSH terms.
Our experimental evaluation shows that citation contexts contain terms that are related to the original document, and that the integration of this knowledge results in better classification performance compared to two state-of-the-art MeSH classification systems: MeSHUP and MTI. Our experiments also demonstrate that the consideration of Section and Distance factors can lead to statistically significant improvements in citation feature quality, thus opening the way for better document feature representation in other biomedical text processing applications.

TITLE: A quantitative appraisal of the genuine contribution of
Turkey and Turkish universities to science (Article, English)

ABSTRACT: Aim: To assess quantitatively the cumulative and genuine
contribution of Turkish universities to science in the main fields over the past 30 years.
Materials and methods: In the Citation Reports section of the Web of Science, over 70 main scientific institutions were searched; and publications that received 60 or more citations by May 2010 were selected. Papers having more than a minor share by international authors were excluded.
Results: Only 47 universities and 6 institutions generated articles that were cited >= 60 times. These publications, numbering 541, received a total of 51.215 citations. Eight universities (Istanbul University, Istanbul Technical University, Hacettepe University, Bilkent University, Middle-East Technical University, Bogazici University, Ankara University, and Ege University) acquired 62% of these citations. Primary authors were
335 individuals among whom 121 generated 70% of these citations. It is estimated that Turkish scientists produce about 1 per mil of the global scientific output, which indicates that about 40 such papers are produced annually in Turkey. A substantial variance was recorded across major universities in terms of the ratio of citations to highly-cited papers to the total citations. Engineering and geology had higher relative contributions, followed by agricultural sciences, ecology, pharmacy, chemistry and medicine, while physics, mathematics, and biology had less contributions.
Conclusion: Along with research in general, research potentially to contribute to science needs specifically to be supported with a coherence, milieu creation and consistent long-term policy.

TITLE: Bibliometric analysis of public health research in
Africa: The overall trend and regional comparisons (Article, English)

ABSTRACT: Many diseases in Africa can be prevented with appropriate
public health interventions. This study aimed to assess the bibliometric characteristics of public health related research articles published by researchers in African institutions from 1991 to 2005. Data used in this study were obtained from the online version of the ISI Web of Science:
Science Citation Index Expanded (SCI-Expanded). Articles published between 1991 and 2005 that had the phrase 'public health' in the title, author keywords or abstract, and had at least one author whose contact address was in an African country, were selected for analysis. The annual number of public health related articles published by African researchers significantly increased from 28 articles in 1991 to 135 articles in 2005, a 382% increase. International collaboration also increased: from 45% of articles having international collaborators during 1991-1995, to 52% during1996-2000, and to 67% during 2001-2005. Collaborations were mostly with European and North American countries. Keywords, subject categories and collaboration patterns of articles varied across regions, reflecting differences in needs and collaboration networks. Public health related research output, as well as international collaborations, have been increasing in Africa. Regional variation observed in this study may assist policymakers to facilitate the advancement of public health research in different regions of Africa, and could be useful for international organisations in identifying needs and to allocate research funding. Future bibliometric analyses of articles published by African researchers, can consider conducting regional comparisons using standardised methods, as well as describing the overall patterns, in order to provide a more comprehensive view of their bibliometric characteristics.
