largest regulator of securities brokers; and they are essentially detailed by the Securities and Exchange Commission to regulate the market in much the same way as the American Bar Association and the AMA regulate their particular areas. Some background on the NASD is included in Figure 1. The particular interest that they had was to try to predict fraud, and to focus their examinations for fraud by accounting for the fact that fraud is a social phenomenon. They particularly came to us because we were involved in doing this kind of work, but we’re taking into account the context, the relations between either people or Web pages or other things.
NASD has a large dataset, and Figure 2 is a rough schema of the data. Intriguingly, this is data that you can access online a single record at a time. We have the entire database, but you can access records on your particular stockbroker if you are interested in finding out if they have engaged in questionable conduct prior to you working with them.
