generating, by the at least one server computing device, a plurality of flags for display in association with respective portions of the review trend, individual ones of the flags corresponding to at least one annotation that describes an information update associated with the at least one item, wherein a selection of a respective one of the flags is configured to cause a rendering of the at least one annotation in association with the review trend; and

encoding, by the at least one server computing device, user interface data comprising the review trend and the plurality of flags for rendering on a client device.

2. The method of claim 1, wherein the request for the review trend is a request for the review trend to be included in a network page.

3. The method of claim 2, wherein the request for the network page is based at least in part upon a user input.

4. The method of claim 3, wherein the user input includes a set of items.

5. The method of claim 3, wherein the user input is a range of temporal values.

6. The method of claim 2, further comprising sending, the at least one server computing device, the network page to the client device for rendering.

7. The method of claim 1, further comprising:

retrieving, by the at least one server computing device, from a memory the plurality of reviews corresponding to the at least one item; and

retrieving, by the at least one server computing device, from the memory the temporal values associated with individual ones of the reviews as retrieved.

8. The method of claim 1, further comprising generating, by the at least one server computing device, a previously nonexistent review corresponding to the at least one item based at least in part upon a dynamic review that modifies the rating provided in association with the at least one item upon an occurrence of a predefined condition.

9. The method of claim 8, wherein the predefined condition is a change in a property of the at least one item.

10. The method of claim 8, wherein the previously nonexistent review comprises a previously nonexistent rating received as user input and a previously nonexisting temporal value.

11. The method of claim 1, wherein the review trend is generated using at least one of:

a rolling average function, a window function, a Steklov function, a curve smoothing function, and a filtration function.

12. The method of claim 1, wherein the at least one item comprises a first item and a second item;

wherein the plurality of reviews comprises a first plurality of reviews for the first item and a second plurality of reviews for the second item; and

further comprising retrieving, by the at least one server computing device, the second plurality of reviews corresponding for the second item, wherein the request sent to the server is for the review trend comprising information pertaining to the first item and the second item.

13. The method of claim 1, wherein the information update is at least one of:

a news article associated with the at least one item, a software update associated with the at least one item, a manufacturer recall associated with the at least one item, or publication of a review of the at least one item.

14. A system, comprising:

at least one computing device;

program instructions executable in the at least one computing device that, when executed by the at least one computing device, cause the at least one computing device to;

generate a review trend for an item specified in a request made through a client device, the review trend comprising a graph generated based at least in part upon a plurality of reviews of the item with respect to a plurality of temporal values, individual ones of the reviews of the item comprising a user-providing rating associated with a purchase of the item, individual ones of the temporal values being associated with a respective one of the reviews of the item, wherein the review trend is generated for a range of the temporal values using a weighted average function that deemphasizes a first subset of the reviews in the review trend received during a first period when a large number of reviews are received relative to a second period, the weighted average function emphasizing a second subset of the reviews received during the second period in the review trend;

generate at least one flag for display in association with the review trend, the at least one flag corresponding to an annotation that comprises an information update associated with the item;

encode user interface data for a display of the review trend and the at least one flag; and

cause a transmission of the user interface data to the client device for the display of the review trend and the at least one flag.

15. The system of claim 14, wherein the review trend is one of a plurality of review trends;

and

further comprising memory accessible by the at least one computing device that stores the plurality of review trends.

16. The system of claim 14, wherein the review trend is generated by processing at least one of:

a rolling average function, a window function, a Steklov function, a curve smoothing function, and a filtration function.

17. The system of claim 14, wherein the range of the temporal values is obtained through a slider component of a user interface generated on the client device using the user interface data.

18. The system of claim 14, wherein the graph comprises the review trend plotted in association with a price of the item over time.

19. A non-transitory computer readable medium embodying program code executable on at least one computing device that, when executed by the at least one computing device, causes the at least one computing device to:

access a plurality of reviews from memory corresponding to at least one item available for consumption in an electronic marketplace and a plurality of temporal values, individual ones of the reviews comprising a user-specified rating associated with the at least one item, individual ones of the temporal values being associated with a respective one of the reviews;

generate a review trend for the at least one item, wherein the review trend graphically illustrates the reviews of the at least one item versus the temporal values, wherein the review trend is generated for a range of the temporal values using a weighted average function that deemphasizes a first subset of the reviews in the review trend generated during a first period when a large number of reviews are made relative to a second period, the weighted average function emphasizing a second subset of the reviews generated during the second period in the review trend;

generate at least one icon in at least one area of the review trend, the at least one icon corresponding to an annotation describing an update associated with the at least one item;

generate user interface data that causes a display of the review trend and the at least one flag; and

cause a transmission of the user interface data to a client device for the display of the review trend and the at least one flag.
