Seventeen songs will participate in the second Semi-Final, and professional juries in each of the participating countries, as well as in Germany, Italy, United Kingdom and Australia, will be voting on tonight's show. They will account for 50% of the overall total.
Each jury will be comprised of five members, (including a chairperson) who will be the same jurors who will also be voting in the Final. They will monitored by an independent notary in each country. The jury consists of a variety of members in terms of age, gender, and background. They are all citizens of the country they are representing.
None of the jury members are connected with any of the participating songs or artists, in order that they can vote independently. All jury members have made signed declarations stating that they will vote independently.
Each jury member will rank all the songs in the show by judging each song, each jury member will focus on the vocal capability of the artists, the performance on stage, the composition and originality of the song, and the overall impression by the act.
The EBU's televoting partner Digame will merge the points given by the jury and the televoters tomorrow night per individual country. If there is a tie between two or more songs between jury votes and televotes, then the song gaining the most televotes will be ranked higher.
You can see a further explanation of the voting in the short video below.
