-==== General ==== 
  
-==== Installation Instruction ==== 
- 
-**  Please read point 2.6 Before starting with these instructions. 
- 
-**  Before installing SemanticVectors you WILL need Lucene (a library for java to search text). 
- 
-== 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 would be necessary.
