Abstract

Claims (36)

1. A computer-implemented method for selecting news articles for presentation on a user device of a user, the method comprising:

measuring dwelltimes for a first plurality of news items, the measured dwelltimes based on an amount of time that each of the first plurality of news item is determined to have been displayed on the user device, each of the first plurality of news items having a plurality of features associated therewith;

training a classifier for determining one or more ranking parameters for ranking news items based on the measured dwelltimes and based on the plurality of features associated with the first plurality of news items, the training including calculating a relative importance of respective features for increasing measured dwelltimes, wherein the one or more ranking parameters are at least based upon a feature determined to have a higher importance than other features of the plurality of features for increasing measured dwelltimes;

ranking a second plurality of news items for presentation on the user device using the one or more ranking parameters determined by the classifier; and

sending one or more of the second plurality of news items to be presented on the user device based on the ranking, wherein the one or more ranking parameters being based upon the feature determined to have higher importance than other features for increasing dwelltimes enables sending of news items expected to increase dwelltimes for the user of the user device.

2. The method as recited in claim 1 , wherein training the classifier further includes:

assigning labels to each news item from the first plurality of news items; and

training the classifier based on the assigned labels.

3. The method as recited in claim 2 , wherein assigning labels further includes:

making a news item label equal to the dwelltime for the respective news item.

4. The method as recited in claim 2 , wherein assigning labels further includes:

making a news item label equal to an integer part of a log of a sum of the dwelltime and 1.

5. The method as recited in claim 2 , wherein assigning labels further includes:

making a news item label equal to an integer part of a log of a sum of the dwelltime and 1; and

truncating the news item label to a predetermined value if the news item label is greater than the predetermined value.

6. The method as recited in claim 1 , wherein the first plurality of news items includes news articles, videos, slideshows, tweets, blogs, or photographs.

7. The method as recited in claim 1 , wherein features include any detectable property, marker, indicator, or attribute of a news item.

8. The method as recited in claim 1 , wherein the ranking is further based on a profile of the user, the profile including features of interest for the user based on items viewed by the user.

9. The method as recited in claim 1 , further including:

training the classifier of news items based on user characteristics, wherein the user characteristics include one or more of gender, or age, or address, or occupation, or online-activity history.

10. The method as recited in claim 1 , wherein the features include one or more of dates, or names, or keywords, or phrases, or people, or publisher, or location.

11. A non-transitory computer-readable storage medium storing a computer program for sending news articles for presentation to a user device of a user, the non-transitory computer-readable storage medium comprising:

program instructions for measuring dwelltimes for a first plurality of news items, the measured dwelltimes based on an amount of time that respective news items of the first plurality of news items are determined to have been displayed on the user device, each of the first plurality of news items having a plurality of features associated therewith;

program instructions for training a classifier for determining one or more ranking parameters for ranking news items based on the measured dwelltimes and based on the plurality of features associated with the first plurality of news items, the training including calculating impact factors of respective features for increasing measured dwelltimes, wherein the one or more ranking parameters are at least partially based upon a feature determined to have a greater impact factor than other features of the plurality of features for increasing measured dwelltimes;

program instructions for ranking a second plurality of news items for presentation on the user device using the one or more ranking parameters determined by the classifier; and

program instructions for sending one or more of the second plurality of news items to be presented on the user device based on the ranking, wherein the one or more ranking parameters being based upon the feature determined to have the greater impact factor for increasing dwelltimes enables sending of news items expected to increase dwelltimes for the user of the user device.

12. The non-transitory computer-readable storage medium storing a computer program as recited in claim 11 , wherein training the classifier further includes:

assigning labels to each news item from the first plurality of news items, wherein assigning labels includes making a news item label equal to the dwelltime for the respective news item; and

training the classifier based on the assigned labels.

13. The non-transitory computer-readable storage medium storing a computer program as recited in claim 12 , wherein assigning labels further includes:

making a news item label equal to an integer part of a log of a sum of the dwelltime and 1.

14. The non-transitory computer-readable storage medium storing a computer program as recited in claim 12 , wherein assigning labels further includes:

making a news item label equal to an integer part of a log of a sum of the dwelltime and 1; and

truncating the news item label to a predetermined value if the news item label is greater than the predetermined value.

15. The non-transitory computer-readable storage medium storing a computer program as recited in claim 11 , wherein measuring dwelltimes further includes:

measuring the dwelltime utilizing one of web beacons or utilizing focus and blur of user browsing activities.
