Authoratory is a unique database of contact information, professional interests, social connections and funding of thousands of leading scientists. The content of Authoratory is produced by a computer program analyzing large amounts of data from PubMed. PubMed is a service of the U.S. National Library of Medicine that includes over 16 million citations from MEDLINE and other life science journals for biomedical articles back to the 1950s. PubMed includes links to full text articles and other related resources.
Authoratory software data-mining techniques make it possible to discover new information about the authors – the information that is not apparent by reviewing one or two of their articles. For each selected author Authoratory gives the following:
- the author status: primary or non-primary (primary author publishes articles independently, while non-primary always publishes articles with another author or a group of authors)
- the list of most frequent coauthors (navigate the social network between the authors using their join publications)
- professional interests (as indicated by the MeSH keywords and by the statistical analysis of abstracts and publication titles)
- the author’s affiliated institution and contact information
- the change of all these parameters across time
Authoratory keyword search is unique as well. It uses keyword frequencies to rank authors against each other. The more papers the particular author publishes for a specific keyword, the higher his rank is in the keyword listings. With Authoratory keyword search it ’s possible to quickly find all authors with expertise in a specific narrow topic.
