Top LinkedIn Groups for Analytics, Big Data, Data Mining, and Data Science in 2016


Big Data and Analytics became the largest group. Overall engagement rates decline, but liking a post is 6.5 times more common than commenting. Machine Learning & Data Science, KDnuggets, and Data Scientists have the highest engagement levels.



3. Engagement



Unlike last year, we did not have the full data on conversations and comments, but we used the data on the latest 200 conversations in each group to estimate these rates per week.

The overall picture, shown in Fig. 3 below, showing continuing decline in average member engagement, from about 1.93 discussions per 1000 members per week in 2015 to 1.17 in 2016, and from 0.55 comments per 1000 members per week in 2015 to only about 0.17 in 2016. So on average, only about 1 in 5,900 group members makes comments, and there is probably an active core of the group which makes most of the comments.

Liking a post is 6.5 times more frequent than commenting - there are on average 1.11 Likes per week per 1000 members.

Here is the global trend.

We can also analyze the groups separately by mapping into quadrants along the axes of Conversations/week/1K members and Engagement/week/1K members, where Engagement is defined as Comments + Likes.
