-==== Installation Instruction ==== 
- 
-**  Please read the very last point before starting this tutorial. 
- 
-This is an installation tutorial for dolts like me, that means, I wrote it after fighting for hours with my lack of intelligence. I hope it help you to install SemanticVectors quickly. You might need several things before installing SV, in particular a java developer kit, a building tool (ant) and Lucene, a library to search text. Everything is documented in this tutorial. 
- 
-== Install Lucene: == 
-  -  You will need JDK and ANT: 
-    -  [[https://​jdk6.dev.java.net/​|JDK]]:​ Development kit for java 
-    -  [[http://​ant.apache.org/​|Ant]]:​ A build-tool for java. Similar to make.  
-  -  You can download both from a repository: <file bash>​sudo apt-get install openjdk-6-jdk 
-sudo apt-get install ant  
-sudo apt-get install ant-doc 
-</​file> ​ 
-  -  You can test your installation with the the following command on your terminal: <file bash>ant -version</​file>​You should get something like<​file bash>​Apache Ant version 1.7.1 compiled on September 8 2010</​file>​ 
-  -  [[http://​ftp.fernuni-hagen.de/​ftp-dir/​pub/​mirrors/​www.apache.org//​lucene/​java/​lucene-3.0.2.tar.gz|Dowload Lucene]] 
-  -  Untar the gz file in your desired location. 
-  -  Go to the target directory. 
-  -  If every thing is allright (if ant is working properly), then run ant in the current directory; it would automatically detect build.xml. <file bash>ant </​file> ​ 
-    -  You will need to set the appropiate CLASSPATH. CLASSPATH specify the location of Java libraries. To check up if the variable is declared in your system:<​file bash> echo $CLASSPATH </​file>​ 
-    -  Althought there are (supposedly) several methods to set CLASSPATH the only one which worked for me was the following: You will have to edit  //bashrc// <file bash>​gedit .bashrc </​file>​ 
-    -  At the end of the document add: <file bash>​export {location of lucene}/​lucene-3.0.2/​lucene-demos-3.0.2.jar:​{location of lucene}/​lucene-3.0.2/​lucene-core-3.0.2.jar"</​file>​ in my case:<​file bash> export CLASSPATH="/​home/​eduardo/​programas/​lucene/​lucene-3.0.2/​lucene-demos-3.0.2.jar:/​home/​eduardo/​programas/​lucene/​lucene-3.0.2/​lucene-core-3.0.2.jar"​ </​file>​ 
-    -  Reboot your computer. Now Lucene should be working. 
-    -  In order to check if everything is all right you should do the following. ​ 
-      -  [[http://​code.google.com/​p/​semanticvectors/​downloads/​detail?​name=kjbible-corpus.tar.gz&​can=2&​q=|Download an example corpus]] ​ 
-      -  Untar the corpus in a desired location. Normally the directory will we: bible_chapters. Go to that directory and run the following command: <file bash>​java org.apache.lucene.demo.IndexFiles {complete bible_chapters path} </​file>​ 
-      - In my case:<​file bash>​java org.apache.lucene.demo.IndexFiles /​home/​eduardo/​programas/​SemanticVectors/​bible_chapters </​file>​ 
-      - If everything runs ok, you should be done. An index directory will be created in bible_chapters. You should be able to perform some simple test using the demo library included in lucene. 
-== Install SemanticVector== 
-  *  This is the binary installation method. You could actually built SemanticVector by downloading the appropriate file and using again ant. I don't recommend it. 
-  -  [[http://​semanticvectors.googlecode.com/​files/​semanticvectors-1.8.jar|Dowload SemanticVector]] .jar file.  
-  -  Move this file to the desire location 
-  -  Again open bashrc and add to CLASSPATH the desire file. In my case it looks like: <file bash>​export CLASSPATH="/​home/​eduardo/​programas/​lucene/​lucene-3.0.2/​lucene-demos-3.0.2.jar:/​home/​eduardo/​programas/​lucene/​lucene-3.0.2/​lucene-core-3.0.2.jar:/​home/​eduardo/​programas/​SemanticVectors/​semanticvectors-1.8.jar"​ </​file>​ 
-  -  Reboot your Computer. 
-  -  By now every thing should be working. Go to the directory where you ran lucene. Run the following command: <file bash>​java pitt.search.semanticvectors.BuildIndex {location in your computer}/​bible_chapters/​index/</​file>​ 
-  -  Now you are ready to use SemanticVectors. In this point I realized that there is a (probably) very serious bug. Since lucene is constantly actualized and SV depends on Lucene, there are several compatibility issues between both. In particular, a class form Lucene has been deprecated in the last version. I checked in the official community and there are not answers to this issue, although others have reported the same problem. Maybe a I get some feedback regarding this problem. Otherwise an older version of the software will be necessary.
