Bibliographic Data

Load bibliometric data from files, the OpenAlex API, or SICRIS/COBISS.

Bibliographic Data

The Bibliographic Data widget.

Overview

Bibliographic Data is the entry point of every Biblium workflow. It reads a bibliographic corpus from one of several sources, normalises the heterogeneous column names of different databases into a common schema (Title, Abstract, Authors, Author Keywords, Index Keywords, Year, Cited by, DOI, …), optionally cleans the keyword/text fields, and emits a single Data table that every other Biblium widget consumes.

Because each database exports list-valued fields with its own separator (Scopus/WoS use ; , OpenAlex uses |), the widget records the source so downstream analyses split authors, keywords and affiliations correctly.

Inputs

  • (none) — this is a source widget.

Outputs

  • Data (Table) — the normalised corpus, one row per document, ready for any downstream Biblium widget.

Loading sources

The widget offers several input modes:

  • File — open a database export (Scopus CSV/RIS, Web of Science, OpenAlex CSV, PubMed, Dimensions, Lens, and 30+ formats). The format and the database of origin are auto-detected where possible.

  • OpenAlex API — query OpenAlex directly (by keywords, author, institution, ISSN/journal or a DOI list), optionally restricting to open-access works.

  • SICRIS / COBISS — load Slovenian personal/institutional bibliographies.

  • Sample datasets — small bundled corpora for learning and testing.

Controls

Database — the source database hint. Leave on Auto-detect for files; it sets the correct list separator and column mapping. Set it explicitly if auto-detection guesses wrong.

Keyword processing — cleaning applied to keyword (and, for the selected categories, Title/Abstract) fields:

  • Apply stopwords — master switch for the cleaning below.

  • General stopwords — a bundled extended English stop-word list, always applied when cleaning is on.

  • Specific categories — domain word-lists (from the bundled stopwords.xlsx) that you can toggle individually; checked categories are removed from keywords and from Title/Abstract.

  • User stopwords file — your own one-word-per-line list to remove as well.

  • Extra stopwords — a quick comma-separated list for ad-hoc terms.

  • Synonyms / thesaurus — rules (old = new) that merge keyword variants into a single canonical form.

What it produces

A clean, column-normalised document table. Typical next steps: OpenAlex Enrichment (add citations/topics/SDGs), Deduplicate & Merge (combine several exports), Filter, and then Main Information / Bibliometric Statistics and the analysis widgets.

Messages

The widget reports when a required column is missing, when a file cannot be parsed, or when an API query returns no records.

Tips

  • For multi-database studies, load each export separately and combine them with the Deduplicate & Merge widget.

  • If keyword-based widgets show merged or odd terms, check the Database hint (it controls the list separator).
