Abstract
Cohort studies collect, generate and distribute data over long periods of time - often over the lifecourse of their participants. It is common for these studies to host a list of publications (which can number many thousands) on their website to demonstrate the impact of the study and facilitate the search of existing research to which the study data has contributed. The ability to search and explore these publication lists varies greatly between studies. We believe a lack of rich search and exploration functionality of study publications is a barrier to entry for new or prospective users of a study's data, since it may be difficult to find and evaluate previous work in a given area. These lists of publications are also typically manually curated, resulting in a lack of rich metadata to analyse, making bibliometric analysis difficult. We present here a software pipeline that aggregates metadata from a variety of third-party providers to power a web based search and exploration tool for lists of publications. Alongside core publication metadata (i.e. author lists, keywords etc.), we include geocoding of first authors and citation counts in our pipeline. This allows a characterisation of a study as a whole based on common locations of authors, frequency of keywords, citation profile etc. This enriched publications metadata can be useful for generating study impact metrics and web-based graphics for public dissemination. In addition, the pipeline produces a research data set for bibliometric analysis or social studies of science. We use a previously published list of publications from a cohort study as an exemplar input data set to show the output and utility of the pipeline here.
Highlights
Cohort studies collect, generate and distribute huge amounts of longitudinal data for health, social and economic research based on a defined group of people over an extended period of time
We demonstrate some of these bibliometric uses and a web based exploration tool based on the augmented metadata set provided by PUMA in this article
One study (Understanding Society) has an advanced searching capability letting users search on author, subject, article type, as well as free text searching on title and abstract
Summary
Generate and distribute huge amounts of longitudinal data for health, social and economic research based on a defined group of people over an extended period of time (often many years). Existing tools There are several well established bibliography management tools in which users can manually curate their own bibliographies and use them to add formatted references to their written work (see https://en.wikipedia.org/wiki/Comparison_of_ reference_management_software for a reasonable list). These include proprietary tools such as EndNote and Mendeley, as well as open source tools like Zotero. Static fields tend to be used in the tools, so an author list is common but a citation count is not These subsets of all available metadata can typically be exported from the various tools in a variety of formats (e.g. BibTeX, RIS). There is little focus on gaining insight from the bibliographies in these software packages beyond grouping by keywords/themes
