Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Ancillary data such as elevation, slope, rainfall, crop planting date, etc., have been recognized for some time as containing useful information for improving data analysis accuracy. However, means for incorporating data of this sort into the analysis process have seen only limited development. For example, ancillary data have been used in a more or less subjective manner in the class definition and training process and in partitioning class sets into mutually exclusive subsets. The purpose of the work reported here is to find more objective and quantitative means for using this ancillary information.Relaxation techniques are a class of iterative procedures under study in the field of picture processing wherein they show promise for reducing ambiguity in scene labeling by developing spatial context.In this paper initial results are presented to show how relaxation techniques can be adapted to the pixel labeling problem to utilize ancillary data in a quantitative and objective fashion. The technique is highlighted by a forestry example in which elevation is used as ancillary data to improve the accuracy of an existing classification of cover types.
