Metamap运行本地提升“查询Prolog Server时出错：连接被拒绝”

Question

I follow this steps to run the Metamap Java API 2014 on Linux platform ( Main page from metamap )

After start Metamap server, I run some main class in Metamap JavaAPI pakages, but it raises Error when querying Prolog Server: Connection refused

Then I check if the Metamap server is running on port 8066 by using the command: sudo netstat -tulpn | grep 8066 sudo netstat -tulpn | grep 8066

but I receive nothing.

Did anyone had the same problem before and knows solution for this?

Answer 1

After running skrmedpostctl (and the optional word sense diambiguation server wsdserverctl ), you need to run the mmserver executable in order to use the Java API for Metamap. This can be run by running the command

./bin/mmserver{two-digit-year}

Also, be sure to include the two jar files for metamap and prolog-beans in your classpath (in your IDE, this can be done by adding a dependency to these jars).

Answer 2

The issue may reside with the timeout: when the timeout parameter is not specified for the MetaMapImpl, it is set to 0, so the instance interprets any latency as failure and reports an error.

Increase the timeout to a reasonable value (for me 500 msec was enough).

Answer 3

I was getting this error after getting error SPIO_E_TOO_MANY_OPEN_FILES and losing the connection to the mmserver. I was tryig to construct instances of MetaMapApiImpl in a loop and calling processCitationsFromString for thousands of times. Therefore, I was getting error SPIO_E_TOO_MANY_OPEN_FILES after around a hundred repeats.

What I did to fix this error was to simply disconnect the api at the end of the loop, by calling the function disconnect() .

You can first start the tagger server by running "skrmedpostctl_start" then you can start the "metamap14.bat", now you can run metamap on command line. But I cannot find "mmserver" so I can't use metamap API. How did you solve that？ PS. The website is extremely user-unfriendly. Some pycho moderator, do u have nothing else to do ? Other Q&A website can answer a question as well as discussion. I am using this website simply because I find a buddy who had the same problem I have. The damn moderator should just shut up and do ur other jobs.
