The invention discloses a method for automatically establishing back-of-book indexes of a book based on book contents. The method comprises the following steps: first, analyzing text in a digital book; taking a chapter as a unit, and performing part-of-speech tagging on the text by using a natural language processing tool to obtain a part-of-speech array; matching by utilizing a high-frequency part-of-speech rule, and extracting candidate phrases; then, classifying to obtain the phrases to serve as candidate index terms by using a support vector machine algorithm by utilizing semantic and grammatical characteristics; calculating the similarity between the candidate index terms and the field corresponding to the book to serve as termhood; calculating information amounts, term frequency, point mutual information and encyclopedia key values to obtain an index degree; calculating a title offset distance, a candidate index term proportion and interestingness to obtain a context weight value; finally, combining the termhood, the indexing degree and the context weight value to obtain an index score, and obtaining the book index terms through limited sequencing. According to the method, the indexes can be added to the book which does not have the back-of-book terms, and the readability and the searchability of the book are improved.

A digital copying device, which serves as an image reading apparatus for improving processing speed by adjusting the timing of various operations when reading is performed using a sheet-through system, causes a first traveling body to move beneath a white reference plate in order to read the white reference plate, and then performs an ADF shading operation to move the first traveling body beneath a sheet-through contact glass. The sheet-through contact glass is then subjected to a dirt detection operation by reading a dirt detection reference plate, whereupon an original is conveyed onto the sheet-through contact glass by an ADF to perform a sheet-through reading operation whereby an image of the original is read. When a sheet-through reading operation is to be performed, the sheet-through reading operation is started following the reception of an image reading request and after the elapse of a time (T=Ts+Tl−Td) obtained by subtracting a time Td, which extends from the beginning of the sheet-through reading operation to the point at which the tip of the original reaches a sheet-through reading position, from the sum of a time Ts required for the ADF shading operation and a time Tl required for the dirt detection operation.
