| 2 | 4 | The algorithm uses a simple way of segmentation. The contents of some HTML tags are (by default) visually formatted as blocks by Web browsers. The idea is to form textual blocks by splitting the HTML page on these tags. The full list of the used block-level tags includes: BLOCKQUOTE, CAPTION, CENTER, COL, COLGROUP, DD, DIV, DL, DT, FIELDSET, FORM, H1, H2, H3, H4, H5, H6, LEGEND, LI, OPTGROUP, OPTION, P, PRE, TABLE, TD, TEXTAREA, TFOOT, TH, THEAD, TR, UL. A sequence of two or more BR tags also separates blocks. |
