As social media plays an increasingly important role in professional and scholarly publishing, taxonomies can be increasingly useful in connecting people of similar expertise and interests with their peers. This can lead to greater opportunities for collaboration, knowledge sharing, and community building. For publishers and scholarly societies, author networks are key to editorial planning, the peer review process, and a wealth of activities supporting the organization and its programs. Taxonomies can play an important role in improving the quality of this “people data,” by enabling name disambiguation and by tagging people’s names with their appropriate subjects.
