Scholarly metrics are a way for the impact of an article, author, or journal to be measured quantitatively. There are different methods used in order to calculate a scholarly impact with the intent that these works will be judged solely on impact to the field as opposed to using criteria without universal standards.
There has been much debate about the use of impact factors in academia. Many academics feel that scholarly metrics place too much emphasis on the quantity of work as opposed to the quality of the work being produced. Another aspect of this debate is the thought that it pressures authors to publish "hot-topic" articles in only the most "impactful" journals as opposed to producing and experimenting with more original work. The use of altmetrics has also added fuel to this debate as many believe the mention of articles/presentations through the social web should be included in the review of their scholarly impact.
