DETERMINING DOCUMENT STRUCTURE SIMILARITY USING DISCRETE WAVELET TRANSFORMATION

摘要

Examples of the present disclosure may include methods, systems, and computer readable media with executable instructions. An example method for determining document structure similarity can include segmenting path sequences (206) of Document Object Model (DOM) trees (120, 462) from a number of web pages (202) into B components (561 ). Path signals (210) corresponding to the path sequences (206) are determined based on a count of the occurrences of particular paths in the Bth component (571 ), and unique path signals (210) are transformed into discrete wavelet signals (214)(572). The discrete wavelet signals (214) are analyzed at multiple DOM tree resolution levels (573).
