Abstract: A method and apparatus for recommending a content, a device, and a medium are provided. The method may include: determining, based on historical behavior data of a user using a product and a feature of a structure of a to-be-recommended content, a target structural preference of the user, the structure being determined by classifying the to-be-recommended content based on any classifying method of a content tag system; and determining each recommendation result of the user based on the target structural preference, the recommendation result including at least two structures and a recommendation content corresponding to each structure.

Abstract: An optical modulator semiconductor device including one or more p-n junctions having a positive doped region and a negative doped region, the p-n junctions being optically connected to at least one waveguide; and an electrode assembly disposed at least partially over the at least one p-n junction, the electrode assembly comprising a first metal layer and a second metal layer, a first electrical signal pathway being formed between the two metal layers at least partially by a dielectric gap, and a second electrical signal pathway being formed by a metal contact from the electrode assembly to one of the positive doped region and the negative doped region. When in use, alternating current (AC) signals are propagated through the first signal pathway and direct current (DC) signals are propagated through the second signal pathway.
