Chinese public procurement document harvesting pipeline

Résumé

We present a processing pipeline for Chinese public procurement document harvesting, with the aim of producing strategic data with greater added value. It consists of three micro-modules: data collection, information extraction, database indexing. The information extraction part is implemented through a hybrid system which combines rule-based and machine learning approaches. Rule-based method is used for extracting information with presenting recurring morphological features, such as dates, amounts and contract awardee information. Machine learning method is used for trade detection in the title of procurement documents.
