Abstract

Community members possess information relating to the community, and share that information with other community members to further the goals of the whole community. Some communities—such as geographic positioning system users, music lovers and mail-order businesses—indirectly hire a professional staff to gather information by purchasing professionally assembled directories. However, professionally assembled directories introduce costs for aggregating what community members may already know, and the professional staff'"'"'s information may not be as accurate as information held by the members. However, simply assembling data from community members may introduce problems of data quality—some community members may be careful, some may be sloppy and some may be malicious.

The present invention relates to a system for building a directory of information from members of a community, by distinguishing between members who have historically provided good data and members who have not. A member'"'"'s data submissions are associated with the member. Corrections to a member'"'"'s data may result in the system being less likely to accept submissions from that member. More submissions and more usage of the member'"'"'s data may result in the system being more likely to accept submissions from that member. The system could compensate members with few corrections, many submissions and many references.

The intent is to create a community-built directory that rivals or exceeds the quality and completeness of professionally assembled directories. Further, a professional organization could incorporate the invention to improve the quality of results from its staff.

The present invention considers an embodiment relating to “location directories,” which contains items characterized by a geographic location, such as businesses, homes, wireless internet hotspots, events, etc.

Aspects of the invention include supporting interfaces, such as automatic methods to prompt users to enter location information, and methods for a user outlining a region (such as a building) on a satellite image or map.

Claims

1. A method of maintaining a directory of items for a community that includes identified sources, comprising:

a. computing a first limit condition, which is a function a first source'"'"'s history information,

b. responsive to the first limit condition being true, performing a first operation that includes

inserting the first item value into an item directory, and

associating the first item value with the first source,

c. performing a second operation that includes

updating the first source'"'"'s history information,

inserting a second item value into the item directory and

associating the second item value with the id of the second source in the item directory,

d. computing a second limit condition, which is a function of the updated first source'"'"'s history information,

e. responsive to the second limit condition being false,

rejecting a third operation initiated in association with the first source,

whereby inserting item information responsive to a limit condition results in accumulating high quality item information, automatically assessing value of the information acquired from sources, which may be individual users, and

limiting the effects of sources whose item values indicate low quality.

2. The method of claim 1,

a. wherein the second operation further includes

removing the association of the first source with the first item value and

removing the first item value from the directory,

whereby corrections can be made without retaining historical item values.

3. The method of claim 1,

a. wherein updating the history information in the second operation includes updating correction information, and

b. wherein the limit condition is affected by the corrections applied to the first source'"'"'s insertions,

whereby the system rejects item insertions from sources who have received frequent or pervasive corrections.

4. The method of claim 1,

a. wherein the limit condition is partly affected by the number of uncorrected item values in the directory associated with the first source,

whereby more prolific authors are not punished by correspondingly increased corrections,

5. The method of claim 1, further comprising

a. identifying a third source,

b. prior to the performance of the second operation, creating a private link associated with the third source to the first item value and updating the first history information to reflect that link

c. responsive to the second limit condition being true, performing a third operation initiated in association with the first source,

whereby the history limit condition can allow more insertions by a source who inserts authored item values that are frequently linked,

whereby sources are encouraged to insert values to which users frequently link.

6. The method of claim 1,

a. further compensating a source based on history information associated with the source,

whereby users contributing valuable item values are appropriately rewarded.

7. The method of claim 1,

a. further identifying a third source,

b. further retrieving the first item value on behalf of the third source, prior to the performance of the second operation,

c. responsive to the second limit condition being true, performing a third operation initiated in association with the first source,

whereby the history limit condition can allow more insertions by a user who inserts item values that are retrieved frequently,

whereby authors are encouraged to insert values that users frequently reference.

8. The method of claim 1,

a. wherein item values contain a geographic position,

whereby the directory can store information about locations,

whereby community members can store and retrieve information about geographic resources, such as stores, facilities, bouys, outdoor events, fishing spots, wireless LAN hot-spots, etc.

9. The method of claim 8,

a. further retrieving the geographic position from an automatic geographic positioning device,

whereby users need not manually enter the location.

10. The method of claim 8,

a. further retrieving item values in order of their proximity to a first geographic position,

whereby a user can find the closest geographic resource in the directory.

11. The method of claim 8,

a. wherein item values contain aspects of entities selected from the group of venues and events.

whereby a user can find venues or events in the directory.

12. The method of claim 8

a. wherein item values contain information regarding availability periods,

whereby a user can find venues or events that are available when convenient for the user.

13. The method of claim 1,

a. wherein item values contain a set of categories,

b. further retrieving an item using a search criteria that includes a category,

whereby users can find items appropriate for their needs,

14. The method of claim 1,

a. further storing the current date and time with the first item value,

b. wherein the second limit condition is sensitive to the elapsed time from inserting the first item value into the directory until inserting the second item value,

whereby a user is not overly punished when information goes out of date.

15. The method of claim 1,

a. wherein the second limit condition is sensitive to the number of links or retrievals made to the first item value prior to inserting the second item value,

whereby a user is not overly punished when useful information becomes not useful over time.

16. The method of claim 1,

a. wherein the second operation further includes marking additional item values associated with the first source as invalid,

whereby indications of a poor quality author can result in the author'"'"'s past contributions being removed from the directory.

17. The method of claim 1,

a. wherein the second limit condition is sensitive to whether the second operation is considered a modification or a correction,

whereby that an item value is incomplete rather than invalid, therefore requiring modification rather than correction, has a different effect on future limitations on the author of the item value.

18. The method of claim 1,

a. wherein obtaining the first item value is replaced by obtaining a series of item values

b. further marking item values as private to a source until a sufficient amount of information is contained in the item values,
