2 Pattern Miner questions

Hi,

I'm now trying Pattern Miner following this Wiki page: https://wiki.opencog.org/w/Pattern_miner. I have 2 questions.

1) Seems libPatternMinerAgent.so is built and working, but not installed under system directory (for Debian, it's /usr/lib/opencog) by default. Is this intentional or a bug? If it's a bug, I'll file an issue or maybe PR.

2) How can I change the n-gram parameter to, say, 3? I put "Pattern_Max_Gram = 3" in cogserver.conf, but seems it ignores and always says like "Finished mining 1~1 gram patterns". and does only 1-gram.

Thanks for help,
MH

this is the old pattern miner. A new pattern miner is being developed,
although it is still not as efficient as the old one in some respects,
it is already usable and more capable in general. However the user
interface is complicated (cause you need to properly set up the URE
https://wiki.opencog.org/w/Unified_rule_engine for it). I'm working on
simplifying that and a manual will follow shortly after.

I'll send a notification on the opencog list when it's user ready,
likely sometime next week.

One thing you check is that if you started the cogserver using cogserver.conf or opencog_patternminer.conf.

If you use below commands then opencog_patternminer.conf is used.

username@xxxxx:~/opencog/build$ ./opencog/cogserver/server/cogserver -c ../lib/opencog_patternminer.conf

Also those config files are copied from opencog/lib/ to the corresponding build folder. When no config file path is specified, the one in the build folder is actually used when you launch the cogserver.

The new user API with some online help for the pattern miner is available

https://github.com/opencog/opencog/pull/3090

Now onto updating the wiki and the README.

Hi,

Thanks for comment. I used opencog_patternminer_nlp.conf and still had problem, but somehow rebuilding opencog fixed this...

Best regards,

Hi Nil,

I'm now trying your new miner

, but got

scheme@(guile-user)> (use-modules (opencog miner))
scheme@(guile-user)> (help cog-miner)
Did not find any object named `cog-miner'

Am I missing something?

Sorry, it's actually cog-mine, not cog-miner

An improved API + README is coming soon, BTW.
