Rules are automatically computed by the ruleminer on a daily basis as soon significant user patterns are identified. But why in my system no rules are automatically generated between two items.Thanks
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
There are a lot of possible explanations for why no rules are generated.First check the Admin Tool an go to the Administration section (link in the upper right corner). There go to plugin logs and check if the rulminer is actually executed. (There should be log entries). If you see entries there you can paste some log output here.
If the Rulminer is running fine and you still see no recommendations it can be that there simply are no significant similarities in user behaviour to find any recommendations. You need at least 2 different users performing the same actions on at least the same 3 items for a third user to see recommendations:
User A views Item 1
User A views Item 2
User A views Item 3
User B views Item 1
User B views Item 2
User B views Item 3
Calculate rules
User C views Item 1 and gets Item2, Item3 as recommendations.
That is the bare minimum for the user to see any recommendations. If the data you sent so far does not show at least this pattern anywhere, you will not get any results!
Given your other thread it may also be a problem with the sessionids. If you set them wrong (always the same one or always a different one), rules will also not be generated!

I have done as you say(Many users view many different items with different sessionids).Rules are generated successfully.But still no recommendations are given for users......
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
If the rules are generated (and your sql file shows they are), they are used to compute recommendations. However, a recommendation list gets filtered before it is sent to the client, based on previous actions of the particular user. The idea is to avoid showing the same items to the same user over and over again. It is possible that you now have created actions for all users on all items, and so all items are filtered out.
To check if that is indeed the problem, try adding an item and view it only with a subset of the users, then run the generators and see if you get recommendations for a different user.

Does the easyrec has functions like Statistics collection sites PV, UV, user behavior data, such as: the length of the user access（how long does a user view one page）, user access depth (how many pages) and other data

Here are my sql file in my database. Please help me analyze the reasons when you have time .Thank you very much.
If the rules are generated (and your sql file shows they are), they are used to compute recommendations.

’try adding an item and view it only with a subset of the users‘ means delete all the items I added before?

Thank you very much. Recommendation items for users is not null now.
Does the easyrec has functions like Statistics collection sites PV, UV, user behavior data, such as: the length of the user access（how long does a user view one page）, user access depth (how many pages) and other data
Unfortunately, there are no statistics to get from easyrec except for what you see in the admin interface.
I have found some useful data about users are existing in the database ,but they have not show us in the admin interface.I will develop it later.
