Abstract

A personalized feed system is described herein that provides feeds that are tailored to the preferences of each user of a real estate website or application. A user signs up to receive a stored profile with the website, and the profile includes information such as what geographical regions the buyer is interested in, what types of homes the buyer is looking for, and so on. The personalized feed system uses this information to provide a feed specific to the buyer that notifies the buyer of listings that are of particular relevance to that buyer. The personalized feed system summarizes other real estate events that are relevant to the user in a single time-oriented feed. Buyers receive information about new and/or modified listings, sales, outstanding offers, status of a transaction, and the like, while sellers receive information about sales, new and/or modified listings, open offers, and so on.

Claims

1. A computer-implemented method of providing a personalized real estate data feed for a user, the method comprising:

receiving user information that specifies one or more types of events of a plurality of events, each said event comprising a respective corresponding modification to a listing of a parcel of real property;

selecting an event source from which real estate information can be received;

connecting to the selected event source;

receiving from the selected event source one or more indications that one or more events of said plurality of events have occurred;

based on the received user information and the received indications, identifying events of which to notify the user;

automatically formatting in extensible markup language a feed item describing at least one of the events;

detecting a feed reader application installed on a computing device associated with the user;

in response to identifying at least one of the events of which to notify the user, providing to the computing device a uniform resource locator (URL) enabling the feed reader to access the formatted feed item and the user to view on the computing device at least one of the events; and

storing correlation information that associates the user with one or more of said identified events, wherein the preceding steps are performed by at least one processor.

2. The method of claim 1 wherein receiving user information comprises accessing a stored user profile for a user to identify configuration information that specifies one or more types of real estate events.

3. The method of claim 1 wherein receiving user information comprises receiving one or more event types to ignore for a user and not place in a personalized feed for the user.

4. The method of claim 1 wherein selecting the event source comprises receiving information from a source selected from the group consisting of a multiple listing service, a county tax data source, a transaction data source, a broker data source, a geographic information source, and a neighborhood information source.

5. The method of claim 1 wherein selecting the event source comprises periodically retrieving information from multiple data sources as part of a separate process to keep up to date real estate information on a real estate search website.

6. The method of claim 1 wherein connecting to the selected event source comprises at least one of accessing a website associated with the event source, invoking a web service application programming interface (API) of the event source, accessing, a file transfer protocol (FTP) site of the event source, or establishing a remote database connection with the event source.

7. The method of claim 1 wherein receiving one or more indications comprises separating the event information into individual events and storing the separate events in an events data structure of a data store.

8. The method of claim 1 wherein receiving one or more indications comprises storing bulk data retrieved from the event source and later extracting events by querying one or more records associated with the bulk data.

9. The method of claim 1 wherein receiving one or more indications comprises defining as an event data that has not changed for a specified period of time.

10. The method of claim 1 wherein identifying events comprises comparing information in the user'"'"'s profile with the received event information to identify one or more events that correlate with a type of event of interest to the user.

11. The method of claim 1 wherein storing correlation information comprises storing reference information from which detailed event information can later be retrieved.

12. The method of claim 1 wherein storing correlation information comprises marking each event with an indication of whether a response is requested from the user to each event.

13. The method of claim 1 further comprising performing the method for each of a plurality of event sources to correlate events from each event source with the user'"'"'s profile information.

14. A computer system for providing a personalized real estate event feed, the system comprising:

a processor and memory configured to execute software instructions embodied within the following components;

a user profile component that stores user profile information for one or more users of the system;

a real estate data store that stores information from one or more event sources that include various sources of real estate related information, user profile information, and user-to-event association information;

an event detection component that detects separate events from the event sources and stores the events in the real estate data store, each said event comprising a respective corresponding modification to a listing of a parcel of real property;

a user-event correlation component that periodically analyzes the real estate data store to identify events relevant to particular users and to associate those events with the particular users;

a feed rendering component that automatically formats in extensible markup language feed items describing at least one of the events;

a feed management component that manages a personalized feed for each user of the system, wherein the personalized feed includes feed items based on the identified events for each particular user in response to identifying at least one event relevant to a particular user, the feed management component detecting a feed reader application installed on a computing device associated with the user, the feed management component further providing to the computing device a uniform resource locator (URL) enabling the feed reader to access the formatted feed item and the user to view on the computing device the at least one event; and

a feed interactivity component that handles user interaction with interactive feed items in the user'"'"'s personalized feed, wherein an interactive feed item can receive a response from the user.

15. The system of claim 14 wherein the user profile information comprises authentication information, preference information that indicates a type of real estate the user is interested in, and one or more transactions the user is a party to.

16. The system of claim 14 wherein the event sources comprise at least one of data streams from a multiple listing service, a county information data stream, and transaction information from a real estate broker from which the system identifies and records events of interest for each user of a real estate website.

17. The system of claim 14 wherein the event detection component identifies separate events based on comparing an earlier version of information received from an event source with a later version and detecting changes between the two versions, wherein each change is classified as a separate event.

18. The system of claim 14 wherein the user-event correlation component produces a set of events associated with each user that the user did not have to manually find, and that are waiting for the user to view in a feed-based format when the user next accesses the system.

19. The system of claim 14 wherein rendering a feed for a user comprises placing the feed items of the user'"'"'s personalized feed in a time-oriented, uniform format according to a well-known standard for consuming data feeds.

20. A non-transitory computer-readable storage medium comprising instructions for controlling a computer system to display a personalized user feed for a user of a real estate application, wherein the instructions, upon execution, cause a processor to perform actions comprising:

receiving user information that identifies a particular user requesting to display the user'"'"'s personalized user feed of real estate events that have occurred in a particular time period, each said event comprising a respective corresponding modification to a listing of a parcel of real property;

retrieving one or more latest feed items that represent events that have occurred in the time period specified;

rendering a feed that mixes feed items from multiple data sources in a uniform format for display in a feed format that is different than the native format of the underlying information;

automatically formatting the feed in extensible markup language;

detecting a feed reader application installed on a computer system associated with the user;

in response to retrieving at least one of the feed items, providing to the user computer system a uniform resource locator (URL) enabling the feed reader to access the formatted feed and the user to view on the user computer system at least one of the feed items;

in response to the computing device accessing the URL, displaying the rendered feed to the user;

receiving a user interaction with an interactive feed item in the displayed feed that requests a user response; and

recording a response indicated by the user interaction and providing the response to a requesting party.
