A Vietnamese information retrieval system for product-price
This addresses the limited availability of such systems for Vietnamese, which is a domain-specific problem for users and researchers in e-commerce and information retrieval.
The authors tackled the challenge of building an automatic Vietnamese product-price information retrieval system by identifying and storing Xpath patterns to extract prices from commercial websites, with experiments showing promising results.
A price information retrieval (IR) system allows users to search and view differences among prices of specific products. Building product-price driven IR system is a challenging and active research area. Approaches entirely depending products information provided by shops via interface environment encounter limitations of database. While automatic systems specifically require product names and commercial websites for their input. For both paradigms, approaches of building product-price IR system for Vietnamese are still very limited. In this paper, we introduce an automatic Vietnamese IR system for product-price by identifying and storing Xpath patterns to extract prices of products from commercial websites. Experiments of our system show promising results.
