The Smart Matches are generated when you make a change in your family tree either via your online family site or if you use the Family Tree Builder Software and synchronize to your website. The data in your family tree will then be compared with over 27 million other family trees at MyHeritage. It may take several days to collect the data, depending on the size of the tree.
The Smart Match technology is very dynamic. In this "intermediate period" web-masters make changes in their family trees sometimes even remove individual profile cards and even entire family trees. The result is that you have received a message that you have a Smart Match, but that the data has been removed. The result is an empty smart match.
I therefore advise you to continue to edit your tree and these empty Smart Matches will disappear in due time.
Just yesterday I came across the following case. MH sent me an email message telling me that several new Smart Matches had been found. When I checked this in the tree, I found for one person only one match of the four that had been announced. I was able to look into one of the "missing" matching trees and found the matching profile.
Now, why do I get a SmartMatch alert for an existing match that is neither displayed in the Smart Match list on my family site nor shown when I click on the green SM sign of the person's card in the tree?
Let's say that our system calculated some matches for you and sent you the e-mail, meanwhile the other user deleted that person from their family tree, and then when you logged to check the match you were notified by e-mail, it did not exist anymore.
It can happen that a user deletes only one person on the tree.
Another case might be that, for instance, a user mistakenly synced from Family Tree Builder more than one tree with same content (duplicated family trees) to a same site. After he/she realised that and deleted one of the trees. Because they were duplicated, it can happen that you will receive an email saying that you received 30 matches from a specific family site (and in that site the user had two duplicated trees). But when you log into MyHeritage to check it, it actually has only 15 matches, because the other user already deleted the duplicated tree.
So, in resume, there can be many different scenarios which can cause you to receive notifications about matches that may disappear before you can actually check them.
Pardon me for insisting on this, but your reply does not match the important point.
Why can I find in the other (matching) tree the profile that has been reported to me as a matching profile but is not displayed as a match when I visit my site? Or to say it in other words, via mail a match is announced (naming the matching profile and the matching tree), this profile is existing in the tree as reported, but is not shown as a match in my tree?
When manually looking at other trees, you may find more matches than get automatically displayed to you. In order to minimize "false positives," i.e., apparent matches that in reality do not match, MyHeritage requires more than one data item to report a match. A matching name along won't do it. If you add a wife to a husband who already generated a match, you would assume that if the name of the wife matches also, this would generate a match for her as well, but it doesn't. MyHeritage considers the evidence insufficient. You need to match one more item, either add her date of birth or add a common child or something. Only then will a match get generated.
MyHeritage is actually doing a fairly good job at balancing the "false positives" (incorrect matches) and the "false negatives" (correct matches that do not get reported).
The problem with the matching system lies elsewhere. When you create a good high-quality tree, other people will copy large portions of it onto their own trees, thereby generating lots of "correct" matches. Ultimately almost every single record in your tree will have a green dot associated with it, thereby making the matching system more or less worthless ... but there is little that MyHeritage can do about this problem.
thank you for the effort you have taken in writing your deteiled answer. But if you read exactly what I have written you may find out that the sitution is just the other way round - a match is announced, it is not shown when I want to see the details but the matching person is there, in my tree as well as in the matching tree.
I can agree to you in every detail that you have mentioned; be sure that I have done a lot with this matching tool even when the matches used to be less smart than they are now. I acknowledge the work that has been done over the years to improve SmartMatching but this does not necessarily mean that there is no opportunity for improvement any more.
Hi, I wonder why my smart matches have disappeared? I look at them, for instance I have 103 smartmatches woth a tree, then as I want to see them, they are gone??? I also try to see existing smart matches, same story, they are gone, so I ask you kindly to fix this, ASAP, best regards Kenneth Holan (myheritage.no)
I have checked your account and noticed that the Smart Matches are active and available on your family site. You can find them all by placing the mouse over the "Discoveries" tab and then clicking on "Smart Matches".
If you have received by e-mail matches from a specific tree of another MyHeritage user, but when you went to check them online they were not available any longer, then please read carefully again my explanation above. The reasons might be:
- The other user from whom the tree you received a match might:
a. deleted the tree
b. made his/her site private
c. turned off Smart Matches feature in his/her family site
d. deleted specific profiles (people) in his/her family tree
Hi, I could believe you, but unfortunately when I open up the smart matches, I see nothing. As far as I'm concerned this goes for every tree in my list. I think at least 20. How can it be? Have everybody privatized their trees now then?
Actually, another one that I did not mention which is less common and more complicated but still possible, is that because of a certain misuse or mistake, a user might publish to their site different versions of a same tree.
For instance: some people, thinking it is a good way to use the site, may bring a GEDCOM he/she created in a different software or website, import it to MyHeritage in order to get Smart Matches or Record Matches, then export it, delete the one from the site, update the tree on the other site, import again a new GEDCOM to MyHeritage and on and on... In resume, they keep adding and deleting trees on a regular basis. This makes that matches are calculated, then blanked (because the tree was deleted/removed from the site).
Or, users create a family tree on Family Tree Builder, and each time they make big updates, they decide to change the name of the file using 'Save project as...' and giving a new name with the date of the last updates... This actually creates a secondary file which is seen by the site as new tree and the matches are calculated again -- and then the person replaces that tree for a new file, and again... Blank matches.
I have analysed your account and noticed that you have many of those Blank Matches. I do believe thought that they are always the same, and until your site is updated and the person on the other side also updates their site, the system will load again from both sides and those blank matches will eventually disappear.
Hi, I know know the reason. My guess is that these persons, like me, suddenly discovertheir tree is gone !!!
OK, I will not use the words I would like to use but please go back to my safety copy, not the latest one, as it happened before that, and fix it. If you choose to ignore it, mae sure you get a very pissed of customer, I had neary 2500 entries in my tree, that will spread the word on how ypu treat customers. Or, looking at this from the bright side, you get one happy customer, telling everybody about how good you are, and how yu helped him after a bad accident, the chpice is yours
I am sure that I have overlooked a post concering this but over the years I have changed programs etc and have ened up with the same individual in my data base severaal times with diffrent information. I foundd how to check for dupllicates and how to export the list to excel. What I want to know is how do I combine the individuals into one the excel spred shheeet is very difficult for me to make sense out of. I have yet to see this addessed in the useerguide or on the website.
You were half way there by using the duplicate checker to find the duplicated person or persons within your tree, now all you need to do is to use the merge function within the Family Tree Builder software.
The following link I have provided for you will assist you with this process.
Hello, I'm thining about change of subscription from Basic to higer plan. During my membersihips i've passed active and inactive statges.
My question is. How long after my subscription ends will be my fammily data kept at MyHeritage site.
