Visual design system for generating a visual data structure associated with a semantic composition based on a hierarchy of components

A visual design system (VDS), the VDS comprising:

• a processor;
• a database to store at least one layout and an associated layout signature wherein said associated layout signature represents a hierarchical composition of semantic component types of its components;
• a unit running on said processor determine a component set signature for an existing layout, to compare said component set signature with at least one associated layout signature of at least one layout from said database to find a set of candidate layouts for said existing layout;
• wherein said unit comprises:
• a signature extractor to extract said component set signature from said existing layout by performing at least one of:
• semantic type mapping of components of said existing layout, dividing sematic types according to visual properties of said components and generating signature elements according to component semantic types;
• a page analyzer to analyze at least said semantic types and to generate said component set signature, said page analyzer comprising at least a layout splitter to divide said existing layout according to at least one of:
• geometrical considerations, semantic links and dynamic layout anchors;
• a layout rater to determine a score for a candidate layout as a function of at least a layout rater learning system, trained on layouts selected and applied by users of said VDS, layouts tested by users of said VDS and discarded, feedback from users of said VDS and actual page viewing/rating information of implemented layouts, wherein said layout rater recalculates said score according to said learning system;
• and
• a ranker to rank candidate layouts according to said qulity score to produce a final set of candidate layouts;
• which are visually diverse and semantically similar to said existing layout;
• and
• an experiment system to create and run at least one experiment using at least one of:
• A/B and multivariate testing on said final set of candidate layouts to gather information on user preferred layouts to present to said user;
• and
• an adapter and applier to adapt at least attributes, component types and content of said existing layout to a user selected preferred quality layout.
