What is an information retrieval service?
The primary function of any information retrieval service (Wikipedia definition) is to provide a collection of information that generally involves a wide range of subjects and is taken from other credible sources.
Prime examples of an information retrieval service would be agencies that specialize in credit reporting, direct mail advertising, dating websites or apartment listing services, etc. Often times these companies will obtain information available to the public and redistribute said information via a database they have created for better and easier access to said information in one easy to navigate location. A good example of this practice would be Apartments.com.
These databases are maintained and updated by the information retrieval service. Sometimes this information can include fact finding or collecting profiles from clients, like a dating website. In most cases, the information obtained will be subject to frequent changes will need to be updated daily. A fee is typically charged for this process and their research. The goal is to provide accuracy and ease of use for their clients.
