Berry picking
Berrypicking (English: Berry = berry + picking = pluck) is a technique of information retrieval , which was described by Marcia J. Bates in 1989.
The classic information retrieval can be described schematically as follows:
Inquiry → Retrieval result
The motivation behind the berrypicking technique is to achieve a more intuitive search technique that is closer to user behavior.
Dynamic information gathering with berry picking
If the user wants to narrow down the amount of information to be searched step by step when searching in a database, the berry picking technique comes into play. When searching through the amount of information, the user can collect parts of information that appear interesting to him at any time (e.g. keywords) and start a new search query. The newly determined amount of information only contains objects that contain the previously collected partial information. The user can repeat this process until he has reached the desired restriction and determined the amount of information relevant to him.
example
All documents in a database that do not contain any previously collected information are removed from the database to be searched. If you select another interesting object from the remaining document list, the list of interesting documents is shortened with each new piece of information until you have reached the desired document list.
