Abstract
A system and method assists a user in selecting a product from multiple products, grouped into categories. Information about the product is received and stored. Attributes about the products of each category, and questions related to the attributes are received and stored. Possible responses to the questions and weights associated with each possible response are also received and stored. Evaluation ratings for each of the attributes of each of the products are received and stored. The user selects a category and is provided with questions corresponding to the attributes of the products in the category selected. For each product in the category, a product score is calculated by summing the product of the weights of the responses by the evaluation ratings for that product. The results are displayed, organized into rows and columns in the order of the product scores and weights. The user may change the weights, change categories, or obtain additional information, such as information about each product, attribute or the evaluation ratings, and may place an order for some or all products.
