1. An apparatus for enriching contents of a current website, the apparatus comprising a memory and a processor, the processor configured to: obtain a corpus from the current website and other websites, and extracting object features from the corpus, wherein the corpus comprises specifications of the object and user reviews about the object; construct multi-dimensional vectors for the extracted features according to the corpus; for a specific feature, make similarity comparison of its multi-dimensional vector and multi-dimensional vectors of other extracted features, wherein the similarity comparison comprises: calculation of mutual information between the specific feature in the corpus and each dimension of its multi-dimensional vector as a weight of each dimension; and calculation of similarities between the multi-dimensional vector of the specific feature in the corpus and the multi-dimensional vectors of the extracted features according to the weights of each dimension, and wherein, the similarities between the multi-dimensional vectors of are calculated based on Euclidean distance; and determine features with similarities being higher than a predetermined threshold as a same feature, and reinforcing the current website with at least one feature which is different from those on the website and corresponding attributes of the at least one feature.
