Recommending electronic content based upon user availability

1. An apparatus comprising:

a computer processor and a computer memory, the computer memory including computer program instructions that when executed by the computer processor cause the apparatus to carry out the steps of:

identifying a time interval for consuming a digital publication, based on schedule information in an electronic calendar;

selecting, based on characteristics of the time interval and a criteria, a digital publication, from a plurality of digital publications, for human consumption within the identified time interval, wherein the characteristics of the time interval include a context indicating a purpose of the time interval;

determine, based on the characteristics of the time interval and the criteria, an extent of the human consumption possible within the identified time interval; and

determine an alternative digital publication selection based on the determination of the extent of the human consumption possible within the identified time interval.

2. The apparatus of claim 1 , wherein the characteristics of the time interval further include one or more of:

day of the week of the time interval;

start time and end time of the time interval;

whether the time interval is indicated as available; or

whether there is a time interval adjacent to the identified time interval that is indicated as available.

3. The apparatus of claim 1 , wherein the context further includes one or more of:

whether the time interval is reoccurring;

whether the time interval spans an entire day; or

whether there is a special notation associated with the time interval.

4. The apparatus of claim 1 , wherein the criteria includes one or more of:

a user profile;

a digital publication profile; or

a purchase price range of a digital publication.

5. The apparatus of claim 4 , wherein the user profile includes one or more of: user age; gender; education; health considerations; commute schedule; or digital publication recommendations.

6. The apparatus of claim 4 , wherein the digital publication profile includes one or more of: genre; author; readability score; type of publication; prior downloaded digital publications; digital publication consumption time estimate; or historical digital publication consumption rate per unit of time.

7. The apparatus of claim 6 , wherein the readability score is determined based on one or more of: Flesch formula; Dale-Chall formula; Gunning fog index; Fry readability graph; G. Harry McLaughlin's Smog Readability Formula, FORCAST formula; a predetermined reading rate; and a readability formula that measures ease with which a publication can be read and understood by a human, or that measures suitability of a publication for reading, understanding, or both by a human.

8. A computer program product comprising a computer readable storage medium, wherein the computer readable storage medium is not a signal, wherein the computer readable storage medium includes computer program instructions that when executed by a computer cause the computer to carry out the steps of:

identifying a time interval for consuming a digital publication, based on schedule information in an electronic calendar;

selecting, based on characteristics of the time interval and a criteria, a digital publication, from a plurality of digital publications, for human consumption within the identified time interval, wherein the characteristics of the time interval include a context indicating a purpose of the time interval;

determine, based on the characteristics of the time interval and the criteria, an extent of the human consumption possible within the identified time interval; and

determine an alternative digital publication selection based on the determination of the extent of the human consumption possible within the identified time interval.

9. The computer program product of claim 8 , wherein the characteristics of the time interval further include one or more of:

day of the week of the time interval;

start time and end time of the time interval;

whether the time interval is indicated as available; or

whether there is a time interval adjacent to the identified time interval that is indicated as available.

10. The computer program product of claim 8 , wherein the context further includes one or more of:

whether the time interval is reoccurring;

whether the time interval spans an entire day; or

whether there is a special notation associated with the time interval.

11. The computer program product of claim 8 , wherein the criteria includes one or more of:

a user profile;

a digital publication profile; or

a purchase price range of a digital publication.

12. The computer program product of claim 11 , wherein the user profile includes one or more of: user age; gender; education; health considerations; commute schedule; or digital publication recommendations.

13. The computer program product of claim 11 , wherein the digital publication profile includes one or more of: genre; author; readability score; type of publication; prior downloaded digital publications; digital publication consumption time estimate; or historical digital publication consumption rate per unit of time.

14. The computer program product of claim 13 , wherein the readability score is determined based on one or more of: Flesch formula; Dale-Chall formula; Gunning fog index; Fry readability graph; G. Harry McLaughlin's Smog Readability Formula; FORCAST formula; a predetermined reading rate; and a readability formula that measures ease with which a publication can be read and understood by a human, or that measures suitability of a publication for reading, understanding, or both by a human.
