A method for detection of page numbers in a document includes identifying a plurality of text fragments associated with a plurality of pages of a document. From the identified text fragments, at least one sequence is identified. Each identified sequence includes a plurality of terms. Each term of the sequence is derived from a text fragment selected from the plurality text fragments. The terms of an identified sequence comply with at least one predefined numbering scheme which defines a form and an incremental state of the terms in a sequence. A subset of the identified sequences which cover at least some of the pages of the document is computed. Terms of at least some of the subset of the identified sequences are construed as page numbers of pages of the document. Additional page numbers may be identified by considering one or more features of the terms in the subset of identified sequences.
