New in Rogue Scholar: filter posts by language

The Rogue Scholar science blog archive received a small update today with the following changes: optionally filter blog posts by language, added support for all OECD fields of science and technology, and searching by DOI. And it passed another big milestone: more than 5,000 (5,483 today) blog posts are now archived.

Filter blog posts by language

Rogue Scholar supports science blog posts in any language and the user interface supports English, Spanish, German, French, Portuguese, and Italian. Ninety percent of the archived blog posts are in English, the rest in German or Spanish. With the new filter you can limit search results to your preferred language, e.g. German:

This new feature hopefully makes it easier to find content in languages other than English and encourages more non-English science blogs to join Rogue Scholar.

Support for all OECD fields

Subject area classification is one important way to find interesting blogs and blog posts. Rogue Scholar started out with the six top-level categories of the widely used OECD Fields of Science and Technology. This week I am adding all 43 second-level categories for a little bit more fine-grained detail. This makes it possible to identify two blogs included in the Rogue Scholar as chemistry blogs and two other blogs as writing about languages and literature.

This is the first iteration of improved OECD fields of science support. Not all categories are already translated into all six supported languages, and the classification into a specific category is sometimes not easy. If you are responsible for a blog on Rogue Scholar, you can change the subject category in your admin dashboard. Future versions of this functionality will support multiple fields of science per blog, and support the (automated) classification of individual posts using machine learning.

Searching by DOI

The full-text index was updated to support searching by DOI, either as identifier for a blog post or in the references. Searching for the Force11 Software Citation Principles (10.7717/peerj-cs.86) for example returns 14 results from six different blogs:

This functionality will be further enhanced in the future by integrating with the Crossref Cited-By service to find citations of Rogue Scholar blog posts elsewhere.
