Our Emergent Concepts chart lets you easily discover the concepts that have changed the most over a specific time period, revealing important trends in your data. The chart itself appears on multiple pages in Kapiche, so we'll first give a general rundown of how to use the chart before discussing how it is used on each specific page.
Emergent Concepts Overview
By default, the Emergent Concepts chart will show concepts that have changed the most during the past 30 days. You can change the time period to a preselected option or enter a custom range using the dropdown illustrated.
If you have no data covering the selected period you will see a message indicating that the chart could not be created. We will be using a custom range for this example as we are looking at historical ISP review data. Below we show the top concepts by % frequency change.
How is change calculated?
Hovering over a concept's row will reveal detailed information about the change it underwent, as shown below.
Given our selected date range of the 1 Jan 2018 to the 31 Jan, 2018 we calculate frequency change as follows:
The first frequency values (150 / 4.84%) are determined by measuring the occurrence of the concept across all data before the start of our date range.
The second frequency value (166 / 5.20%) is determined by the occurrence of the concept across all data, up to and including the end of our date range.
Both raw and percentage frequencies are determined by subtracting the first frequency from the second, yielding 16 / 0.36%
This pair of values reveals how much the concept increased in frequency both overall and relative to the total volume of data during the specified time period.
In the case of a preselected date range (last 30 days) first and second date boundaries are calculated automatically relative to the current day. Specifically, the first date boundary will be 30 days prior to the current date, and the second date boundary will be set as the current date.
What is relative change?
You'll also notice in the tooltips a statistic called 'relative change'.
Relative change helps to gauge the magnitude of change proportionate to the average of the two frequencies and is calculated as follows:
This metric can be useful in highlighting less prevalent concepts that have still undergone significant change. Below we illustrate by showing that dropouts has a higher degree of relative change than days despite a significant lower change in frequency. In this sense you can think of relative change as measuring the acceleration of change for a concept.
Chart sorting options
By default the chart is sorted by Frequency %, in decreasing order, emphasizing concepts increasing in frequency. If you click on the Freq (%) header, it will reverse the sort order and show concepts decreasing in frequency. You can also click on the Freq (#), which will show the concepts with the greatest increase or decrease in raw frequency.
When the Emergent Concepts chart appears on the Unmapped Verbatims page, it shows concepts with the biggest change based only on the subset of data that is not already captured in a saved query. Because of this, you are more likely to detect the beginnings of new, unique themes rather than changes within existing themes that you are tracking. The query drilldown of the Dashboard is the best place to achieve the latter.
When the Emergent Concepts chart appears on the overview page of the Dashboard, it shows concepts with the biggest change based on all data available to the dashboard. When filters are not applied, you will see concepts with the biggest changes across the whole dataset showing you emerging trends regardless of whether they overlap with existing saved queries or not.
By applying dashboard filters you'll change the data used by the Emergent Concepts chart, allowing you to pinpoint key changes within a specific customer segment.
You'll also see the Emergent Concepts chart when drilling down into a query on the Dashboard. Like with the overview page of the Dashboard, filters will allow you to examine a particular segment of the data. In addition, the Emergent Concepts chart will be restricted only to the data that matches the query being examined. This allows you to monitor new, emerging facets and changing discourse for a particular theme.
