Can you make sure you ran mvn install package and following dependency (fastutil) is present in your local mvn repository.

<dependency> <groupId>it.unimi.dsi</groupId> <artifactId>fastutil</artifactId> <version>6.5.12</version> </dependency>

Thanks for your reply!

After I ran mvn install package, I got a new folder named "target", under which I can see the following:

Then, I cd into folder "classes", and ran
"java -Xmx10G com.yahoo.semsearch.fastlinking.FastEntityLinker --help"
, and got the following error:

I wonder whether I ran the project wrongly. Thanks a lot!

Please run the command in the project's working directory i.e., ~/zphuang/git/FEL

[zphuangHKUCS]

Thanks for your reply. Even though I run the command in the working directory, the same error happens. I am afraid that I have not downloaded the dependencies. The following pic shows the target folder.

Is it normal that we only have two .jar files?

@zphuangHKUCS Can you try following command

mvn clean compile exec:java -Dexec.mainClass=com.yahoo.semsearch.fastlinking.FastEntityLinker Dexec.args=" en/english-nov15.hash" -Dexec.classpathScope=compile

[zphuangHKUCS]

Thanks for your reply. But I still encounter an error:

Anything new on this issue? @zphuangHKUCS @aasish

I'm dissapointed for not find a solution for these basic problems, I tried a lot of ways in order to run the FEL project but it was not possible. I hoped a basic runnable example, more if coming from Yahoo team.
For Entity Identification, I recommend the Stanford project (https://nlp.stanford.edu/software/CRF-NER.shtml). They have a clear explanation, working examples and an online demo (http://nlp.stanford.edu:8080/ner/process).

@zphuangHKUCS @ArthurCamara @emilioalvarado
The error mentioned in @zphuangHKUCS's latest comment is due to missing hyphen in Dexec.args.
This project requires a valid Maven installation as a dependency (as listed in the README).
