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.
