Systems and methods for accessing historical data are provided. Based upon
user interaction, a time period of interest and historical data, the
systems and methods perform cross-correlation algorithms and interpret
which items are to be accessed and displayed to the user via a user
interface vis-a-vis a timeline portion and navigation region. Based on
frequency and recency usage patterns, and/or user preferences, items are
assigned relative weights and displayed accordingly in the timeline
portion and navigation region of the user interface. Each item that can
be displayed within the system has a unique identification, which may be
translated to one or more visual symbols within the user interface. In
various non-limiting embodiments, the system leverages a distributed
database store which stores and indexes items that make up a digital
history. When a request is made to the database, items, such as events,
places, people and things, are automatically cross-referenced and
correlations are drawn based on filtering criteria.
