Abstract

Managing data collection for one or more scheduled alert messages. A primary or backup poller manager coordinates any number of poller services to access content and generate the alert messages. At a predefined period the poller manager is informed that an existing or new poller service is available for work. The poller manager provides a query to the poller service to access content in which one or more users have expressed an interest. Querying for a large number of users can be subdivided among the poller services. The poller service can also automatically expand the query if it yields insufficient content. The poller service generates the alert messages for the interested users and informs the poller manager when done. A change in content can be used to generate or update alert messages before their scheduled delivery. The poller manager prioritizes processing with a quality of service level.

Claims

1. A method for data collection, comprising:

determining at a predefined period that one of a plurality of poller services is available for work;

instructing the one of the plurality of poller services to access validated content from an authenticated source that corresponds to a predefined selection for at least one user in receiving an alert message comprising at least one portion of the validated content;

instructing the one of the plurality of poller services to generate at least one alert message based on the validated content; and

updating a task list upon receiving an indication that the one of the plurality of poller services has generated the at least one alert message for delivery to the at least one user.

2. The method of claim 1, further comprising authenticating a source for content and validating content for data collection to obtain the validated content.

3. The method of claim 1, wherein determining is performed by a secondary poller manager after the one of the plurality of poller services attempted to notify a primary poller manager that the one of the plurality of poller services is available for work.

4. The method of claim 1, further comprising determining which of the at least one user has selected to receive the at least one alert message corresponding to the validated content.

5. The method of claim 1, further comprising at least one of:

adding the one of the plurality of poller services to a list of available poller services; and

selecting the one of the plurality of poller services from the list when another one of the plurality of poller services is busy.

6. The method of claim 1, further comprising:

assigning the validated content a quality of service level; and

determining, based on the quality of service level, when the validated content will be used to generate the at least one alert message.

7. The method of claim 1, further comprising at least one of:

updating the alert message based on a difference between the validated content and a previous content; and

generating the alert message based on the difference between the validated content and the previous content.

8. The method of claim 1, wherein the validated content is accessed based on a query expression corresponding to the predefined selection of the at least one user.

9. The method of claim 8, wherein the query expression is accessed from a user profile of the at least one user.

10. The method of claim 9, further comprising:

determining that the validated content is inadequate; and

revising the query to access alternate content.

11. The method of claim 1, further comprising:

accessing additional content if the at least one alert message was not generated within a predetermined period of time; and

considering both the validated content and the additional content to determine when to generate the at least one alert message.

12. The method of claim 1, further comprising:

determining a time at which the validated content is accessed;

determining a period during which the validated content is not used to generate the at least one alert message; and

determining that an additional poller service is needed if the period exceeds a predefined threshold period.

13. The method of claim 1, further comprising throttling notifications that the plurality of poller servers are available for work.

14. A system for data collection, comprising:

a processor;

a communication interface in communication with the processor and in communication with an authenticated content source; and

a memory in communication with the processor and storing data and machine instructions that cause the processor to perform a plurality of operations, including;

determining at a predefined period that one of a plurality of poller services is available for work;

instructing the one of the plurality of poller services to access validated content corresponding to a predefined selection for at least one user in receiving an alert message comprising at least one portion of the validated content;

instructing the one of the plurality of poller services to generate at least one alert message based on the validated content; and

updating a task list upon receiving an indication that the one of the plurality of poller services has generated the at least one alert message for delivery to the at least one user.
