Abstract

The present invention relates to an information processing apparatus which objectively evaluates book reviewers. According to the information processing apparatus, a book evaluation program retrieves, for each book, the book reading period of time per page, the number of lent-out times, the number of turned-over pages and the total number of turned-over pages, the number of pages turned over two times or more, and the number of book reading times included in the book reading data received from a bookstore server to obtain their deviation values for each book and obtain the average value of these deviation values. On the basis of the average deviation value obtained for each book, the book evaluation program obtains a five-step evaluation value. The book evaluation program obtains the absolute values of the difference between the five-step evaluation value for each book for each reviewer and a reader'"'"'s evaluation value and obtains the average value of the absolute values based on the number of times the evaluation has been made to obtain the evaluation capability value of each reviewer, thereby recording the obtained evaluation capability values to review data.

Claims

1. An information processing apparatus comprising:

display means for displaying an electronic book;

operation means for operating a display state of said electronic book displayed by said display means;

operation log accumulation means for accumulating an operation log of operations done by said operation means; and

transmission means for transmitting said operation log accumulated by said operation log accumulation means to an other information processing apparatus.

2. The information processing apparatus according to claim 1, wherein said operation log includes at least one of the number of turned-over pages, the number of pages turned over two times or more, display count, and display duration of time, each associated with said electronic book.

3. An information processing method comprising the steps of:

displaying an electronic book;

operating a display state of said electronic book displayed in said display step;

accumulating an operation log of operations done in said operation step; and

transmitting said operation log accumulated in said operation log accumulation step to an other information processing apparatus.

4. A computer program for causing a computer to execute the steps of:

displaying an electronic book;

operating a display state of said electronic book displayed in said display step;

accumulating an operation log of operations done in said operation step; and

transmitting said operation log accumulated in said operation log accumulation step to an other information processing apparatus.

5. An information processing apparatus comprising:

reception means for receiving operation logs of a display state of an electronic book received from a plurality of other information processing apparatuses which display said electronic book;

book evaluation value computation means for computing, on the basis of said operation logs, a book evaluation value for said electronic book;

reviewer evaluation value storage means for storing a plurality of reviewer evaluation values of each book reviewer for said electronic book;

comparison means for comparing said book evaluation value with said reviewer evaluation values; and

comparison result storage means for storing a comparison result obtained by said comparison means.

6. The information processing apparatus according to claim 5, wherein said operation log includes at least one of the number of turned-over pages, the number of pages turned over two times or more, display count, and display duration of time, each associated with said electronic book.

7. The information processing apparatus according to claim 6, wherein said book evaluation value computation means obtains deviation values of at least one of the number of turned-over pages, the number of pages turned over two times or more, display count, and display duration of time, each associated with said electronic book included in said operation log and obtains an average deviation value by averaging said deviation values to compute a book evaluation value for said electronic book as a five-step value to be set by said average deviation value.

8. The information processing apparatus according to claim 6, wherein said reviewer evaluation value is a five-step value to be set to said electronic book by said book reviewer.

9. An information processing method comprising the steps of:

receiving operation logs of a display state of an electronic book received from a plurality of other information processing apparatuses which display said electronic book;
