    • A system, method and computer program product for indexing a product identifier and logical parts thereof includes receiving a product identifier; splitting the product identifier into logical parts; indexing the product identifier and the individual logical parts in an index; and storing the index, wherein the index is created by encoding the product identifier and the individual logical parts of the product identifier into separate fields of a document, wherein different weights are assigned to separate fields based on the field types such as product identifier or logical parts of the product identifier field, wherein different weights are assigned to words based on the word types including bi-words, wherein the fields and weights are encoded to word positions in the document, wherein the weights affect a score generated upon performing a query using the index. A system, method and computer program product for processing a search query is also presented.

    • Methods for generating value-based information are presented. Methods for displaying product information are also presented. In one approach, a feature to price distribution is approximated for each of a plurality of features of a plurality of products. Additionally, a product feature score is computed for each of at least a subset of the products. Furthermore, data corresponding to a visual representation of the at least a subset of the products in relation to each other is output based on the product feature scores and prices of each of the at least a subset of the products. In another approach, a value is assigned to each of a plurality of features of a plurality of products. Additionally, a product feature score is computed for each of at least a subset of the products. Furthermore, data corresponding to a visual representation of the at least a subset of the products in relation to each other is output based on the product feature scores and prices of each of the at least a subset of the products.
    • 提出了生成基于价值的信息的方法。 还介绍了显示产品信息的方法。 在一种方法中,针对多个产品的多个特征中的每个特征来估计价格分布的特征。 另外,针对产品的至少一个子集中的每一个计算产品特征得分。 此外,基于产品的至少一个子集的产品特征得分和价格,输出与产品相关的至少一个子集的视觉表示相对应的数据。 在另一种方法中,将值分配给多个产品的多个特征中的每一个。 另外,针对产品的至少一个子集中的每一个计算产品特征得分。 此外,基于产品的至少一个子集的产品特征得分和价格,输出与产品相关的至少一个子集的视觉表示相对应的数据。
