Dear Wikiwand AI, let's keep it short, summarize this topic like I'm... Ten years old or a College student

A personal knowledge base (PKB) is an electronic tool used to express, capture, and later retrieve the personal knowledge of an individual. It differs from a traditional database in that it contains subjective material particular to the owner, that others may not agree with nor care about. Importantly, a PKB consists primarily of knowledge, rather than information; in other words, it is not a collection of documents or other sources an individual has encountered, but rather an expression of the distilled knowledge the owner has extracted from those sources or from elsewhere.[1][2][3]

The term personal knowledge base was mentioned as early as the 1980s,[4][5][6][7] but the term came to prominence in the 2000s when it was described at length in publications by computer scientist Stephen Davies and colleagues,[1][2] who compared PKBs on a number of different dimensions, the most important of which is the data model that each PKB uses to organize knowledge.[1]:18[3]
