Social tagging systems have established themselves as an important part in today's web and have attracted the interest of our research community in a variety of investigations. This has led to several assumptions about tagging, such as that tagging systems exhibit a social component. In this work we overcome the previous absence of data for testing such an assumption. We thoroughly study social interaction, leveraging for the first time live log data gathered from the real-world public social tagging system BibSonomy. Our results indicate that sharing of resources constitutes an important and indeed social aspect of tagging.
Researchers repeatedly discovered primary pharmaceutical contaminants, their metabolites, and transformation products in aquatic ecosystems. Body metabolism may not convert consumed pharmaceuticals to their metabolic elements before excretion. In this case, clinical and industrial wastes ensure their presence in the environment. Nevertheless, conventional wastewater treatment methods are ineffective for removing pharmaceutical wastes. Once in the ecosystem, they alter the physiological response of nontarget exposed aquatic and even terrestrial organisms due to induced toxicity.
A Pew Internet survey explores how people approach the search for information. What are the implications for librarians tasked with improving digital and information literacy?
