Abstract: Certain example embodiments provide systems, methods, apparatuses, and computer program products for monitoring homesharing activity. For example, certain embodiments may determine how well each resident, in a residential apartment complex, is performing in relation to homesharing. Some embodiments may provide a technology platform (referred to herein as a “scoring platform”) that generates a homesharing score based on how much money a resident is making, how long it takes the resident to respond to guest messages, the ratings the resident receives on short term rental websites, the resident's hosting status, and how much money each resident has made in relationship to how much a company makes on units that the company manages and subleases. This score may then be used to target specific residents to assist them in the areas in which they are considered to be underachieving.

The resulting SCR-active iron-containing molecular sieves exhibit a selective catalytic reduction of nitrogen oxides with NH3 or urea at 250° C. that is at least 50% greater than if the iron-containing molecular-sieve were calcined at 500° C. for two hours without performing the hydrothermal or thermal treatment.

The method still further includes installing each data element reaching the path's leaf node, as a feature, into one or more recommender algorithm models.
