A method and apparatus is provided for producing a general data extraction procedure capable of extracting data from data sources on a network regardless of data format. The general data extraction procedure is determined from a plurality of pairs of data from the network, each pair including a data source and a program which accurately extracts data from the data source. The pairs of data are processed by a learning system to learn a general program for extracting data from new data sources.
