Sample text

26 CHAPTER 2 Learning from user interactions We begin by abstracting the various types of content, so that the concepts and algorithms can be applied to all of them. 4, most applications generally consist of users and items. An item is any entity of interest in your application. Items may be articles, both user-generated and professionally developed; videos; photos; blog entries; questions and answers posted on message boards; or products and services sold in your application. If your application is a social-networking application, or you’re looking to connect one user with another, then a user is also a type of item.

The set of tags changed as the type of content visited by the users changed. Further, the content displayed when a user clicked on a tag varied from user to user and changed over time. Some tags pulled the data from a search engine, while others from the recommendation engine and external catalogs. In the next release, they allowed the users to explicitly tag items by adding free text labels, along with saving or bookmarking items of interest. As users started tagging items, John and Jane found that there was a rich set of information that could be derived.

These four basic conditions are that “wise crowds” are effective when they’re composed of individuals who have diverse opinions; when the individuals aren’t afraid to express their opinions; when there’s diversity in the crowd; and when there’s a way to aggregate all the information and use it in the decision-making process. Collective intelligence is about making your application more valuable by tapping into wise crowds. More formally, collective intelligence (CI) as used in this book simply and concisely means To effectively use the information provided by others to improve one’s application.
