Abstract: A system and method for determining quality of written product reviews to distinguish the user reviews for further use or processing. In one embodiment, the opinion analyzer system includes a processor, a parser module, an prose analyzer module, a characteristic features database, and a language value rules database. In another embodiment, the method comprises the steps of parsing language of a portion of a user review, extracting characteristic feature from the user review, determining a quality parameter based on the extracted characteristic feature, determining a raw score based on the quality parameter, and determining quality of the user review based on the raw score.

Abstract: A method and system for automatically generating a naturally reading narrative product summary including assertions about a selected product. In one embodiment, the method includes the steps of determining at least one attribute associated with the selected product, selecting an alternative product, retrieving assertion models to describe the product and to recommend an alternative product in a natural manner, and generating a naturally reading narrative by combining the attribute and the selected alternative product with the retrieved assertion models such that the generated narrative includes a recommendation of the selected alternative product. A system is provided for implementing the described method.

Abstract: A catalog taxonomy organized in a tree-like configuration including at least one first tier product category having at least one first tier attribute associated with products in the first tier category, and a plurality of second tier product categories branching from the first tier product category and defining subcategories, at least one of the plurality of second tier product categories having a second tier attribute associated with products in a subcategory defined by the plurality of second tier product categories, wherein each of the second tier product categories inherits the first tier attribute of the first tier product category from which the plurality of second tier product categories branches. In addition, a system and method utilizing such catalog taxonomy.

Abstract: A system and method for automatically generating a naturally reading narrative product summary including assertions about a selected product. The method includes the steps of determining an attribute associated with the selected product, retrieving an assertion model defining forms in which an assertion can be manifested to describe the product in a natural manner, and generating a naturally reading narrative by combining the attribute with the retrieved assertion model. A product summary generator comprises a product attribute module adapted to determine an attribute, an assertion model module adapted to retrieve an assertion model, and a summary generation module adapted to generate a naturally reading narrative by combining the attribute with the retrieved assertion model. A computer readable medium for automatically generating a naturally reading narrative product summary including assertions about a selected product is also provided.

Abstract: An on-line commerce method and apparatus. A user can select products for purchase from plural merchant servers by examining product information stored on a shopping server. The product information related to selected products is verified by accessing a checkout page of each merchant server. The verified information is then presented to the user for confirmation. Upon confirmation, buy procedures are executed on each merchant server to purchase the products using existing account information for the user at each merchant server.
