Abstract: A facility for valuing a distinguished home located in a distinguished geographic area is described. The facility receives home attributes for the distinguished home. For each of a plurality of valuation sub-models, the facility applies the valuation sub-model to the received home attributes to obtain a sub-model valuation for the distinguished home. The facility further applies a meta-model to the record home attributes to obtain a relative weighting factor for each sub-model. The facility then uses the obtained relative weighting factors to combine the sub-model valuations to obtain an overall valuation for the distinguished home. The facility reports the obtained valuation for the distinguished home.

Abstract: A facility procuring information about a distinguished property from a user knowledgeable about the distinguished property that is usable to refine an automatic valuation of the distinguished property is described. The facility displays information about the distinguished property used in the automatic valuation of the distinguished property. The facility obtains user input from the user adjusting at least one aspect of information about the distinguished property used in the automatic valuation of the distinguished property. On a later day, facility displays to the user a refined valuation of the distinguished property that is based on the adjustment of the obtained user input.

Abstract: A method for a firewall-aware application to communicate its expectations to a firewall without requiring the firewall to change its policy or compromise network security. An application API is provided for applications to inform a firewall or firewalls of the application's needs, and a firewall API is provided that informs the firewall or firewalls of the application's needs. An interception module watches for connect and listen attempts by applications and services to the network stack on the local computer. The interception module traps these attempts and determines what user is making the attempt, what application or service is making the attempt, and conducts a firewall policy look-up to determine whether the user and/or application or service are allowed to connect to the network. If so, the interception module may instruct the host and/or edge firewall to configure itself for the connection being requested.
