Abstract: The present invention discloses a book information collaboration system and method, which can improve the efficiency of information exchange among readers of a same book and be advantageous for the readers to enhance the understanding of the book in a collaborative manner. The technical solutions are as follows: an open collaboration group is generated when a certain book is created for the first time, and a default entry structure using this book as a root entry is also generated. The entry structure involves various contents such as book publication information, book content reconstruction and reader comments. A user who searches, reads or attempts to recreate this book subsequently will be automatically added in this collaboration group. Only members in the collaboration group can edit the entry structure. The updated entry structure is displayed in real time to the members in the collaboration group.

Abstract: The present invention discloses a method for combining entry structures, by which similar entry structures can be automatically combined. By this method, the efficiency in both retrieving entries and acquiring knowledge is improved. In a technical solution, this method comprises: converting an entry structure into a text; combining, in the format of text and based on a cosine similarity between entries and a cosine similarity between entries and texts, a plurality of texts into one text; and converting the combined text back to the entry structure.
