Guide route generation methods and systems. A target object is first selected by a visitor. The similarity or interest of candidate objects corresponding to the target object is calculated. Recommended objects are selected from the candidate objects according to the corresponding similarity or interest. A guide route is generated to link the recommended objects. The interest of the visitor is dynamically determined. If the interest is changed, the interest of the candidate objects is re-calculated, and recommended objects are re-selected from the candidate objects to generate a new guide route.
