Time Processing

These scripts are provided to help you customize your time-related analysis. First the Period Detector automatically computes most homogeneous periods of your dataset according to a given variable. Period Slicer is then useful to define custom periods.

Period Detector

Period Detector

Composition of the dataset at different time steps Period detector directly works on the frequency distribution of (a) given field(s) to produce a matrix that maps the distance between the composition of the dataset at two different time steps (in the example above indexed by years for instance). Field One should define the fields to ...
Epic Epoch

Epic Epoch

Epic Epoch is a simple script for tracking dramatic changes in the composition of a field over time.   How Epic Epoch works It acts in three steps: First, the N most frequently occurring entities are selected at each time period, A frequency timeline is built for each of the selected terms A bump graph ...
Period Slicer

Period Slicer

Period Slicer allows users to customize the time periods according to which the corpus is analyzed. Parameters When launching Period Slicer, you need to input the different time periods which will be used to split the corpus. Each time period should be separated by semi-colons. Lists of values A time period is defined by a ...
