For example, real estate descriptions in natural language may not be directly suited for specific search filters that potential buyers want to apply.
a hierarchical data structure representing the real estate property enables specialized filtering (e.g., based on the number of bedrooms, number of floors, or the requirement of having a bathroom with a toilet on the first floor), and is expected to also benefit related applications such as automated price prediction (Pace et al., 2000;Nagaraja et al., 2011).
