A lot goes a long way: data quality improvement at DOAJ

Since 2012, DOAJ has been on a path of data quality improvement. DOAJ metadata is used all over the world and all over the Web. Improving and fixing the quality of our metadata can be painstaking work but the effort goes a long way as changes propagate across the Web via search engines, aggregator databases, library portals and other databases.

Along these lines, the largest publisher (in terms of the number of journals) in DOAJ recently added missing abstracts to over 100,000 articles and fixed broken special characters in approximately 2000 more. This was a huge effort on their part and DOAJ is grateful for the work that has gone into this project. It is an achievement that will be welcomed by DOAJ metadata consumers.

To date, Hindawi has 161,334 articles loaded to DOAJ and until recently was the largest contributor of metadata to our index. That title was taken from them recently when DOAJ ingested the entire PLOS archive from Europe PMC.

Deduplication of article metadata

Housekeeping! We’re doing some important data cleanup work, improving the accuracy of our data, making it more reliable and relevant for you, our users:

DOAJ is working on cleaning up article-level metadata as we remain committed to maintaining a high-quality directory. We have recently developed tools to assist with the automated pruning of spurious records. As a result you may see the number of articles in DOAJ go up (new articles continue to be accepted) and down (as spurious records are deleted). We already have processes and checks in place to ensure that no new spurious records will enter the catalogue.

Let me know if you have any questions!
