SYSTEMS AND METHODS FOR DETECTION OF CONTENT OF A PREDEFINED CONTENT CATEGORY IN A NETWORK DOCUMENT

There is provided a method of identifying data object(s) of a predefined content category within a network document for presentation at a client terminal, comprising: receiving, at a network node at an internet service provider level of a network, web resource elements of a network document for rendering and presentation on a display associated with a client terminal; identifying data objects within the network document; extracting classification features from each data object; classifying at least one of the data objects into a predefined content category; generating reformatting instructions for adapting the presentation of the network document to reduce visibility of the data objects classified into the predefined content category upon rendering of the network document; creating a formatted network document by injecting the reformatting instructions into the network document for implementation by a rendering process executing on the client terminal; and transmitting the formatted network document to the client terminal.
