Terminology/Pariser: Definition Lock-in effect: this is when users are so heavily involved in a service that it would be too costly to switch to another provider. For example, in addition to its search engine, Google also offers Google Mail, Google Voice, Google Docs, etc. This makes it easier to stay with one company than to use a different provider for each service.
Retargeting: the data of visitors to a website who do not buy anything (about 98 percent) will be resold. The searchers will then receive a new offer when they continue their search. Retargeting means that companies do not have to accept a "no" as the final answer.
Pull Media/Pariser: Media such as web browsers, with which you have to actively search for something. On the other hand there are:
Push media: Television and newspaper subscriptions, the information appears on the screen or in the mailbox without your intervention.
Serendipity/Pariser: refers to a coincidental discovery of something that one did not seek in reference to the Persian fairy tale of the three princes of Serendip, who make such unexpected discoveries.
Local Maximum/Matt Cohler/Pariser: a local maximum occurs when trying to optimize something. After a temporary search activity, the search engine evaluates the searched item as the most interesting thing for the user in question, even though it is not. Problem: if information about click behavior is sold to advertisers, this can lead to an "identity loop".
Identity loop/Pariser: a self-reinforcing mechanism: you get more filtered search results you do not really care about. If you click on them, the loop will be reinforced and it is not impossible to get interested.
Nice-World-Syndrome/Dean Eckles/Pariser: Eckle's thesis (1): because of the nature of the liking negative things get out of focus. A button for highlighting could also have been called "important" - but in this way, everything that comes into consciousness or to which the attention of others should be directed is called "Like".
