Abstract: A method of selecting a website for delivery of targeted content to an audience member computer based on attitude values associated with audience members who participate in a computer implemented survey is disclosed. The survey response information, as well as website visitation information, and demographic information associated with the audience members may be collected and stored in a central database. An attitude value may be determined from the survey response information and/or the other information for the audience members. The attitude value may indicate the audience member's view about an issue, topic, product, service or the like. The attitude value in conjunction with other website visitation information may be used to select a website for delivery of the targeted content to the audience members.

Abstract: A computer-implemented method can include receiving multiple survey response sets, where each survey response set includes the responses of a survey taker. A maximum weight spanning tree can be defined. Each node of the maximum weight spanning tree can represent a survey question. Directional edges can connect nodes. A weight for each directional edge can be defined that represents mutual information of two nodes connected by that directional edge. A fraud detection score can be defined for each survey response set based on a conformance of response values for that survey response set to the mutual information represented by the edges of the maximum weight spanning tree. A distribution of the fraud detection scores can be determined, and a subset of the survey response sets can be classified as fraudulent based on the fraud detection scores associated that subset being statistical outliers in the distribution of fraud detection scores.
