Behavior-based associations are extrapolated to items for which the quantity of collected user activity data is insufficient to create meaningful or reliable behavior-based associations (“behavior-deficient” items). The behavior-based associations are extrapolated based on content-based associations, or another type of “substitutability” association, between the behavior-deficient items and other items. The items can be any type of item for which user behaviors (e.g., purchases, accesses, downloads, etc.) can be monitored and analyzed to detect behavior-based associations, and for which item content or other available information can be used to assess item substitutability. For example, the items can be products represented in an electronic catalog, web pages or other documents accessible on a network, or web sites.

The invention relates to a pollution prevention and vegetation recovery method for a metal sulphide ore solid waste storage yard. The method comprises the following steps of conducting stabilizing treatment on side slopes of the storage yard, laying a two-way geogrid, building intercepting ditches in the slope faces of the storage yard, spraying an acidic improvement layer, laying a flexible isolating layer, laying ecological sticks, laying a two-way geogrid, spraying a base material layer, spraying a seed layer and laying a protective layer, so that plants have sufficient water and nutrition during growth.
