Agent Toolbox can also generate data extraction rules to parse a given web page. Again, there is no need for users to program the data extraction rules. Instead, Agent Toolbox ‘learns’ these rules from users' labels on the web page with a machine learning algorithm (12,13). As a result, we can efficiently configure, repair and maintain the agents. Agent Toolbox also enables FASTSNP to be extended, so new functionalities can be included by deploying more web wrapper agents. For example, haplotype information is a new function that we included recently by producing an agent to access HapMap (4). Currently, a total of 11 agents are deployed by FASTSNP. A detailed explanation of how Agent Toolbox works is beyond the scope of this paper. For the most recent report, please refer to Ref. (2).
