A method includes receiving a request to print a current web page. A set of records that represent web pages that are similar to the current web page are identified from a print log that includes at least one record, each record including an indication of a web page and indicating one or more objects that had been previously selected for printing from that web page. Based on the objects that are indicated by the identified set of records, one or more objects of the current web page are selected to be printed on a printer.

Automatic selection of web page objects for printing

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 () of Document Object Model (DOM) trees () from a number of web pages () into B components (). Path signals () corresponding to the path sequences () are determined based on a count of the occurrences of particular paths in the Bcomponent (), and unique path signals () are transformed into discrete wavelet signals ()(). The discrete wavelet signals () are analyzed at multiple DOM tree resolution levels ().

Discrete wavelet transform method for document structure similarity

Disclosed is a method of automatically extracting data from a target web page, comprising selecting () data in a source web page; determining () the respective DOM (document object model) trees of the source and target web page, and identifying the one or more nodes comprising the selected data in the source web page DOM tree; determining () matching paths in the respective DOM trees; for selected data in a node of an unmatched branch of the source web page DOM tree, identifying () the nearest matched path in the source web page; identifying () the unmatched branch nearest to the corresponding matched path in the target web page; determining () if said identified unmatched branch in the target web page DOM tree comprises a target node matching the selected data node; and if so: extracting () data from the target node if the mismatch between the respective unmatched branches does not exceed a predefined threshold. A computer program product and system implementing this method are also disclosed.

Data extraction method, computer program product and system

An exemplary embodiment of the present may generate a DOM-tree and generate a signal based on the DOM-tree and a node list. The signal may be analyzed and nodes may be selected within the signal to form a periodic wave. Repeat patterns may be detected using the periodic wave and the nodes.
