The JournalTOCs big metadata

without comments

Every day, we create approx 5 thousand new records; most of those records are metadata of journal articles published in the previous 24 hours. The following image represents the metadata that JournalTOCs has collected so far.

JournalTOCs Big Metadata

The table illustrated at the left hand side is a sample of the data source for this big metadata. It represents the number of new articles per day found in the journal TOC RSS feeds in March 2013.

Roughly 70% of that metadata was gathered in the last two years alone since JournalTOCs was launched as a public service in May 2011. As today, this metadata represents data of 1,795 publishers, 10,200 Premium users from licensed institutions, 22,050 journals, over 100,000 tracked research interests collected from followed journals that are frequently visited by any user (free and Premium registrations) and near 8 million articles that were published in the last 5 years. This big metadata is more than a matter of size. It can be an opportunity to find insights in new and emerging types of research, to support or create library management systems, and to help to answer questions regarding research publications. JournalTOCs offers ways to harvest this opportunity. It uses web services and standard harvesting protocols to open the door to the possibilities given by this big metadata, including:

+ Harvesting the metadata of all the journals indexed by JournalTOCs, which includes title, ISSN numbers, access rights, subject classification, publisher, number of follower, last issue published date, the URL of the journal RSS feeds and the journal homepage

+ Harvesting the complete database of the metadata of 8 million articles, including all the content collected from their RSS feeds

+ Querying the metadata of specific journals by ISSN or keywords in the journal title

+ Searching for articles in the current issues or the backfile issues
