Waivio: Domain Expertise

In this video, we explore what domain expertise is and how it differs from reputation score on Steem.

A user's domain expertise is the total sum of author and curation rewards accumulated by the user over a period of time:

User domin expertise
Note: Currently, the domain expertise is being calculated since the public launch of Waivio.com in June 2019. In the future, we plan to index the entire history of Steem blockchain.

Author rewards are proportionally allocated to the hashtags and object references made by users in their posts:

Calculating the domain expertise
Curation rewards are also taken into account. Thus, if a user upvotes a post that has links to some hashtags, that user will begin to build expertise in those hashtags as well.

The domain expertise accumulated by users can be found on their profiles on Waivio:

Domain expertise of users
The combined domain expertise of a user is equal to the sum of their expertise in all the different hashtags they have referenced in their own posts or indirectly upvoted.

For example, based on Steem blockchain records, we can estimate that for @detlev #beersaturday is twice as important as #travel. 😃

In a similar way, each hashtag on Steem now has the list of associated experts:

Looks like @meesterboom has more expertise in #beer than @detlev! And @rollie1212 is already in the top 10!

As you can see, the domain expertise differs from the standard reputation score on Steem in many unique ways and it allows a much more granular analysis of users' interests.

Finally, the domain expertise can also be calculated for the hashtags themselves and it makes it easy to evaluate which topics are important for the Steem community overall:
