Conveying Accuracy

I’ve mentioned a few times that I plan to get my Genealogical research onto a website eventually. One of the things I’ve been considering for the design of my website is how to convey the accuracy of the information; after all, genealogical research is fraught with accuracy issues.

This is described well in 5 Ways To Tell If Your Genealogy Research Is Accurate.

I think there are several types of accuracy I’ll wish to convey about the records I’ll have used. Here are my thoughts on them.

Transcription Accuracy

I use a range of records, from those I have seen photographs of the original document and made my own transcriptions (5 star) through to facts I’ve been told by other people without any documentary evidence to back it up (1 star). I can imagine a rating scale something like this.

Star rating Meaning
☆☆☆☆☆ I have seen the document, or a photograph of the document that the transcription was made from.
☆☆☆☆ Full transcription provided by someone else without a photograph, e.g. Ancestry website Scottish census records.
☆☆☆ Partial transcription provided by someone else without a photograph, e.g. Ancestry website Scottish Old Parish records.
☆☆ Fact provided from someone else with a note of the record where they found it, but without any transcription.
Fact provided from someone else without any documentary evidence to back it up.

Recording accuracy

There are various ways to look at the accuracy of the recording; the distance in time since the event, e.g. age on a death record; the likelihood of the informant knowing the information, e.g. a neighbour instead of a relative; the kind of record, e.g. a statutory record versus something less formal or rigorous. I can imagine a rating scale something like this.

Star rating Examples
☆☆☆☆☆ Birth/Marriage/Death date from Statutory record of the same.
☆☆☆☆ Age from Statutory Marriage Record.
Parents marriage date on Statutory Birth record of child.
☆☆☆ Age from Statutory Death Record if recorded by a relative.
Age from Census Record.
☆☆ Age from Statutory Death Record if recorded by a neighbour.
Any other record/fact not listed above.

5 stars

Overall accuracy of a Fact

There therefore needs to be a formula that conveys the likely accuracy of any one fact recorded for a person, for example if the birthdate comes from a Statutory Birth Record that I have seen the image of, that would be 5-stars on both of the above scales, and therefore the best possible score, however if it doesn’t match all the other records for the same fact, like all the ages on census returns, then that should reduce the score. I suspect I’m going to have some fun trying to come up with said formula!

Overall rating for a person

Having given each fact a score, the average of all the scores could be used to convey an overall rating for each person.

I suspect these ideas will solidify over time and, especially, when I try to put them into practice when I get to the point of creating my website. I will no doubt find other examples that need rated, and complications to any formula that I come up with. Should be fun though!
