...During the recognition process, if a surface is recognized as “floor,” then the algorithm will identify that the valid semantic labels of a surface orthogonal to it can only be “wall” or “door,” but not “ceiling,” thereby reducing the search space [16]....

...For example, the semantic network methods for recognizing components using context work well for simple examples of hallways and barren, rectangular rooms [16,68], but how would they handle spaces with complex geometries and clutter, such as an office or a bathroom? In Section 7, we identified and discussed a number of technology gaps in automated as-built BIM creation capabilities....
