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

Two periods detected 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). One should define the fields to consider for constructing frequency vector profiles ...
Epic Epoch

Epic Epoch

Epic Epoch is a simple script for tracking dramatic changes in the composition of a field over time. 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 shows the evolution of frequency ...
Period Slicer

Period Slicer

Period Slicer allows users to customize the time periods according to which the corpus is analyzed. Parameter: 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. A time period is defined by a series of integer ...
