Abstract: Techniques are described for computing devices to perform automated operations related to using images acquired in a building as part of an automated generation process of a floor plan or other mapping information for the building, in some cases without using depth information from depth-sensing equipment about distances from the images' acquisition locations to objects in the surrounding building, and for subsequent use in further automated manners, such as controlling navigation of mobile devices and/or for display to end users in a corresponding graphical user interface. The automated analysis and assessment of the building images may, for example, include incrementally generating partial versions of the mapping information, determining acquisition instructions related to further acquisition of additional images and/or other types of data (e.g.

Abstract: Systems and methods for rearranging tags on a graphical user interface (GUI) based on known and unknown levels of web traffic are disclosed. To provide users with real estate listings that have popular home attributes with respect to a given region, the system uses known user interaction information to determine predicted user interaction information for real estate listing phrases (e.g., tags) that are associated with unknown user interaction information. The system then ranks the real estate listing phrases based on each real estate listing phrase's user interaction information. Based on the ranked real estate listing phrases, the system generates for display the highest ranked real estate listing phrase in association with a real estate listing being associated with the real estate listing phrase.

Abstract: Techniques are described for automated operations related to analyzing visual data from images captured in rooms of a building and optionally additional captured data about the rooms to assess room layout and other usability information for the building's rooms and optionally for the overall building, and to subsequently using the assessed usability information in one or more further automated manners, such as to improve navigation of the building. The automated operations may include identifying one or more objects in each of the rooms to assess, evaluating one or more target attributes of each object, assessing usability of each object using its target attributes' evaluations and each room using its objects' assessment and other room information with respect to an indicated purpose, and combining the assessments of multiple rooms in a building and other building information to assess usability of the building with respect to its indicated purpose.

Abstract: Techniques are described for automated operations to analyze visual data from images acquired in multiple rooms of a building to generate one or more types of building information (e.g., global inter-image pose data, a floor plan for the building, etc.), such as by simultaneously or otherwise concurrently analyzing groups of three or more images having at least pairwise visual overlap between pairs of those images to determine information that includes global inter-image pose and structural element locations, and for subsequently using the generated building information in one or more further automated manners, with the building information generation further performed in some cases without having or using information from any distance-measuring devices about distances from an image's acquisition location to walls or other objects in the surrounding room.

Abstract: A real estate showing appointment management system manages showing appointments based on a health parameter of a showing contact. The health parameter can be the body temperature. The system includes a server system running a server software application and software application running on a device. The software application configures the thermometer of the device to take body temperature of the showing contact. The thermometer can be an infrared thermometer. The software application determines whether the body temperature meets a threshold relying on the server system or by itself. When the showing contact passes the health check, the software application retrieves a showing directive for the showing contact to proceed with showing the listing of a showing appointment. The showing directive is presented by the device for the showing contact.

Abstract: Techniques are described for using computing devices to perform automated operations to generate mapping information via analysis of visual data of photos of a defined area, and for using the generated mapping information in further automated manners, including to display the generated mapping information via various types of visualizations corresponding graphical user interfaces. In some situations, the defined area includes an interior of a multi-room building, and the generated information includes at least a partial floor plan and/or other modeled representation of the building—in addition, the generating may be further performed without having measured depth information about distances from the photos' acquisition locations to walls or other objects in the surrounding building. The generated floor plan and/or other mapping-related information may be further used in various manners, including for controlling navigation of devices (e.g., autonomous vehicles), etc.

Abstract: Systems, methods and apparatus are provided for generating electronic transactional documents using a form generating system. The electronic transactional document may be created using a design tool that allows a user to place data entry fields over an image or snap shot of a transactional document. Rules, default values, and attributes associated with the date entry fields may be established as the electronic transactional document is being created.

Abstract: A facility for estimating a home improvement rate of return for a geographic area is described. The facility accesses information about homes in the geographic area including sale prices and data describing home improvements performed on the homes, such that some of the sale prices are associated with homes having a home improvement of a particular type. The facility obtains automatic valuations for the homes based on the homes' attribute values, and calculates the differences between the automatic valuations and the sale prices. The facility analyzes the differences and the home improvement data and, based on the analysis, estimates a rate of return of the particular type of home improvement.

Abstract: Techniques are described for automated operations to analyze visual data from images acquired in multiple rooms of a building to generate multiple types of building information (e.g., to include a floor plan for the building), such as by using a trained neural network to jointly generate the multiple types of building information by combining visual data from pairs of the images, and for subsequently using the generated building information in one or more further automated manners, with the building information generation further performed in some cases without having or using information from any distance-measuring devices about distances from an image's acquisition location to walls or other objects in the surrounding room. The automated operations may include generating some types of building information with respect to each image pixel column, and other types of building information by combining data from both images of a pair.

Abstract: A variety of improved techniques for homebuyers to access undeveloped and/or uncompleted communities with homes that are not yet built and lots that are not yet parceled or recognized with addresses are disclosed.

Abstract: A home view data structure is described. The home view data structure is made up of multiple entries. Each entry contains information identifying a home; and a quantitative value scoring the view available from the identified home, such that the contents of the data structure are usable to compare the identified homes on the basis of the views available from them.

Abstract: Techniques are described for using computing devices to perform automated operations involved in analysis of images acquired in a defined area, as part of generating mapping information of the defined area for subsequent use (e.g., for controlling navigation of devices, for display on client devices in corresponding GUIs, etc.). The defined area may include an interior of a multi-room building, and the generated information including a floor map of the building, such as from an analysis of multiple 360° spherical panorama images acquired at various viewing locations within the building (e.g., using an image acquisition device with a spherical camera having one or more fisheye lenses to capture a panorama image that extends 360 degrees around a vertical axis)—the generating may be further performed without detailed information about distances from the images' viewing locations to objects in the surrounding building.

Abstract: A system for updating a database comprises an input interface and a processor. The input interface is configured to receive image data. The processor is configured to determine from the image data one or more attributes of a database entry for real estate property and update the database entry for the real estate property.

Abstract: A guided search system for suggesting and arranging filter criteria within a user interface for presentation to a user to help guide the user's search for listings is disclosed. The system builds one or more filter criteria frequency data structures indicative of the number of times each filter criterion has been used to filter search results and how often different filter criteria are used together. The system uses the frequency data structures to predict which filter criteria a user will likely employ to narrow their search given the filter criteria the user has already used. The system provides techniques for arranging or rearranging filter criteria within a user interface, by moving, placing, or ordering suggested filter criteria within the user interface, where a user is likely to be able to recognize and interact with the placed filter criteria, based on the determined amounts of use.

Abstract: The described techniques relate generally to managing in-person access of users to physical properties based at least in part on tracking geographical locations of devices of the users, such as by using one or more geofences created around a physical property to provide authorized users with temporary access to the physical property based at least in part on tracked geographical locations of devices of the users. In some situations, a specialized server provides information to a user's mobile device about the geofence(s), and the mobile device notifies the specialized server when it breaches one or more of the geofences. The specialized server may perform further related activities, such as perform tracking of locations of users as they move around a physical property, and further analyzing the tracked location information to determine associated information and initiate corresponding additional automated activities.

Abstract: Techniques are described for using computing devices to perform automated operations related to providing visual information of multiple types in an integrated manner about a building or other defined area. The techniques may include generating and presenting a GUI (graphical user interface) on a client device that includes a computer model of the building's interior with one or more first types of information (e.g., in a first pane of the GUI), and simultaneously presenting other types of related information about the building interior (e.g., in additional separate GUI pane(s)) that is coordinated with the first type(s) of information being currently displayed. The computer model may be a 3D (three-dimensional) or 2.5D representation generated after the house is built and showing the actual house's interior (e.g., walls, furniture, etc.), and may be displayed to a user of a client computing device in a displayed GUI with various user-selectable controls.

The system then ranks the real estate listing phrases based on each real estate listing phrase's user interaction information. Based on the ranked real estate listing phrases, the system generates for display the highest ranked real estate listing phrase in association with a real estate listing being associated with the real estate listing phrase.

Abstract: A facility for estimating a value relating to an occurrence is described. The facility receives a first occurrence specifying a first value for each of a plurality of independent variables that include a distinguished independent variable designated to be monotonically linked to a dependent variable. The facility subjects the first independent variable values specified by the received occurrence to a statistical model to obtain a first value of the dependent variable. The facility receives a second occurrence specifying a second value for each of the plurality of independent variables (the second values varying from the first values in a first direction). The facility subjects the second independent variable values to the statistical model to obtain a second value of the dependent variable, the second value of the dependent variable being guaranteed not to vary from the first value of the dependent variable in a second direction opposite the first direction.

Abstract: A facility for determining a housing index value for a subject geographic region for a subject period in time is described. For each home in a set of homes within the subject geographic region, the facility determines home attribute values; applies a first valuation model and second valuation for the subject geographic region to the home attributes to obtain estimated values of the home at the beginning and end of the subject period, respectively; and determines an appreciation rate for the home on the basis of the estimated values of the home at the beginning and end of the subject period. The facility combines the appreciation rates to obtain an aggregate appreciation rate for the subject period, and combines the aggregate appreciation rate for the period with a housing index value for a prior period to obtain the housing index value for the subject geographic region and subject period.

Abstract: A facility for estimating a subject home's value is described. For each of one or more direct home attributes, the facility determines the value of the direct home attribute for the subject home. For each of a plurality of arbitrary geographic regions of different sizes containing the subject home, the facility determines information relating to the geographic region as a whole. The facility then subjects the determined values and information to a statistical home valuation model to obtain an estimated value of the subject home.
