Abstract

A computer-implemented method for identifying and assessing public health events, and a corresponding system and apparatus, includes capturing public health-related information from structured and unstructured sources, where the information is contained in one or more documents, extracting meta-data from the captured public health-related information, creating an index of the extracted meta-data; archiving the meta-data and the documents, where the index links meta-data to its associated document, processing the extracted meta-data according to one or more detection algorithms to determine if an anomaly exists, and where an anomaly exists, providing a public health event notification, and monitoring and evaluating the responses to the public health events.

Claims

1. A global disease surveillance platform for identifying, determining, and analyzing potential public health events and monitoring responses thereto, comprising:

an interface configured by computer-executable instructions to;

receives external information feeds comprising structured and unstructured data;

transform the structured and unstructured data into a schema consistent with a schema of the platform;

extract meta-data from the structured and unstructured data, index the meta-data, and relate the meta-data back to the structured and unstructured data; and

store the structured data, the unstructured data, and the meta-data in a storage device;

an external services module that provides services to facilitate the responses; and

a platform processor coupled to the interface and the external services module and configured by computer-executable instructions to;

analyze the meta-data in relation to one or more thresholds and to trigger transmission of a public health alert by an alert module; and

identify, evaluate, tag, and correlate the structured data, the unstructured data, and the corresponding meta-data to produce a data file related to a specific public health event; and

provide real-time user access to the data file for pre-planning, detection, and response to the public health event.

2. The platform of claim 1, wherein the external services comprise geo-spatial services.

13. The platform of claim 1, wherein the unstructured data comprises data selected from the group consisting of audio, video, blog, body of an email, and word processor document.

16. The platform of claim 1, wherein the analysis module is configured to analyze the meta-data using at least one of the following algorithms:

moving average, CuSum with EWMA, recursive least squares, wavelet, cluster detection, Bayesian analysis, and heuristics.

3. An apparatus for managing phases of a public health event, the apparatus including one or more suitably programmed computing devices, the apparatus comprising:

an interface configured to receive structured and unstructured data from one or more external data sources and further comprising;

a data transformation module that transforms data from the structured and unstructured data sources into a schema consistent with a schema of the apparatus, and

a data classification module that extracts meta-data related to the structured and unstructured data and creates an index of the meta-data back to the meta data'"'"'s structured or unstructured data;

a data store coupled to the interface, wherein the indexed meta-data and the structured and unstructured data are stored;

a processing component coupled to the interface, comprising;

an analysis module configured to analyze the meta-data in relation to one or more thresholds and to trigger transmission of a public health alert by an alert module; and

access modules configured to provide real-time user access to the structured and unstructured data, and to the corresponding meta-data for pre-planning, identification, detection, and response to the public health event.

4. The apparatus of claim 3, further comprising external services coupled to the processing component, wherein the processing component is configured to receive geo-spatial information and to populate one or more geo-spatial products with the extracted meta-data, wherein the populated geo-spatial products provide visual and temporal displays of progress of the public health event, including indications of populations at risk from the public health event, and wherein the geo-spatial products allow monitoring of effectiveness of response actions.

5. The apparatus of claim 4, wherein the populated geo-spatial products further provide visual indication of locations of public health response assets.

6. The apparatus of claim 3 wherein the analysis module is further configured to trigger a notification of an event or anomaly to one or more users of the apparatus by the alert module.

7. The apparatus of claim 6, wherein the alert module incorporates a triage algorithm for notification of the users.

8. The apparatus of claim 3, wherein the index provides retrieval of structured and unstructured data, corresponding to the indexed meta-data, from the data store, for further analysis.

9. The apparatus of claim 3, further comprising a virtual meeting room, wherein analysis of the public health event-related data are displayed and information related to the public health event are received from users of the apparatus.

14. The apparatus of claim 3, wherein the unstructured data comprises data selected from the group consisting of audio, video, blog, body of an email, and word processor document.

17. The apparatus of claim 3, wherein the analysis module is configured to analyze the meta-data using at least one of the following algorithms:

moving average, CuSum with EWMA, recursive least squares, wavelet, cluster detection, Bayesian analysis, and heuristics.

18. The method of claim 14, wherein analyzing the meta-data comprises using at least one of the following algorithms:

moving average, CuSum with EWMA, recursive least squares, wavelet, cluster detection, Bayesian analysis, and heuristics.

10. A method for managing a response to a public health event during an entire life cycle of the event, the method executed on one or more computing devices including at least one processor, the method comprising:

receiving information contained in one or more structured and unstructured data sources;

initially processing the information, comprising;

extracting, using the at least one processor, meta-data from the data sources, wherein the meta-data are linked to their corresponding data source,

transforming, using the at least one processor, the extracted meta-data,

classifying, using the at least one processor, the transformed meta-data to create indexed meta-data, and

storing, using a storage device, the indexed meta-data and their corresponding data source, wherein the indexed meta-data allows retrieval of the corresponding data source; and

analyzing, using the at least one processor, the meta-data to determine if a threshold value indicative of a public health event has been exceeded, wherein if the threshold has been exceeded,

providing an initial public health event alert, and

continuing, using the at least one processor and the storage device, to collect, process, and analyze information to allow management of the response.

11. The method of claim 10, further comprising:

applying one or more detection algorithms to the meta-data to determine the extent of the public health event and to prepare and subsequently manage the response to the public health event; and

archiving information related to the public health event.

12. The method of claim 10, wherein the public health event is one of acute, mild, and chronic conditions, wherein the public health event affects one or more of humans, animals, and the environment, and wherein the public health event is caused by one or more of natural, technological, man-made, and bio-terrorism mechanism.
