How can you tell if a name is male or female?
Most names are predominantly used for either males or females, so a statistical approach will often yield good results. There are of course names that are used across both sexes, but a statistical approach will reveal that too. Furthermore, naming conventions can rely on cultural differences, so scoping statistics to a single country will help achieve more accurate results.
How accurate is gender prediction?
Gender prediction works by statistical probability and as such it is hard to talk about accuracy. If a certain name yields a female probability of 92%, it means that 92% of our dataset for that name is female. If your own data is unbiased, it will be correct 92% of the time.
For a comparison of gender inference methods you can read Lucía Santamaría and Helena Mihaljević (2018), Comparison and benchmark of name-to-gender inference services.
