Apparatus and method for providing electric book

An apparatus for providing an electronic book, comprising:

• a book configuration module configured to receive book information as a response to a book information detection request signal including a book identifier, arrange the word identifier of a changeable word and a fixed word, which are included in the book information, generate an electronic book for a user by arranging a changeable word received as a response to a word detection request signal including a user reading level of the user and the word identifier, and output an output request signal including the electronic book;
• a book storage module configured to store book information constituting an electronic book, and transmit book information to the book configuration module in response to the book information detection request signal of the book configuration module, the book information including text information composed of the word identifier of the changeable word and the fixed word;
• a word storage module configured to associate each of changeable words constituting an electronic book for the user with a word level and a word identifier, store the changeable word associated with the word level and the word identifier, primarily detect changeable words corresponding to the user reading level in response to the word detection request signal of the book configuration module, detect the changeable word associated with the word identifier among the primarily detected changeable words, and transmit the detected changeable word to the book configuration module;
• an output module configured to detect the electronic book for the user from an output request signal in response to the output request signal of the book configuration module, and output the electronic book;
• and
• a level setting module configured to set the word level of the changeable words,
• wherein the book configuration module generates the electronic book for the user by arranging a changeable word whose word level is corresponding to the user reading level,
• wherein the word storage module stores the changeable words for each user such that the word levels associated the changeable words are different for at least two users,
• wherein the level setting module counts the number of exposures of each of the changeable words included in the electronic book for the user outputted from the output module, and generates a word level down request signal indicating lowering the word level of the changeable word for the user whose exposure count is equal to or more than a preset exposure count, and
• wherein the word storage module lowers the word level, for the user, of the changeable word corresponding to the word level down request signal.
