ILSP Focused Crawler

h1. Getting Started

Once you [[DeveloperSetup|build]] or [[HowToGet|download]] an ilsp-fc runnable jar, you can run it like this

<pre><code>java -jar ilsp-fc-1.1-jar-with-dependencies.jar</code></pre>

There are several settings that influence the crawling process and can be defined in the configuration file (the default file is crawler_config.xml) before the crawling process. Some of them can also be set in the command running the ilsp-fc runnable jar, as follows:

-a :user agent name 

-t :the crawl duration in minutes. Since the crawler runs in cycles (during which links stored at the top of the crawler’s frontier are extracted and new links are examined) it is very likely that the defined time will expire during a cycle run. Then, the crawler will stop only after the end of the running cycle. The default value is 10 minutes.

-n :the crawl duration in cycles. 

h2. Run a monolingual crawl

<pre><code>java -jar ilsp-fc-1.1-jar-with-dependencies.jar crawlandexport -a vpapa@ilsp.gr -cfg FMC_config.xml -t 10 -type m -c 10 -lang de -of output_test1_list.txt -ofh  output_test1_list.txt.html -tc Automotive-seed-terms-de.txt  -u  Automotive-seed-urls.txt -xslt -f -k</code></pre>

h2. Run a bilingual crawl

<pre><code>java -jar ilsp-fc-1.1-jar-with-dependencies.jar crawlandexport -a test1 -c 10 -f -k -l1 de -l2 it -t 10 -of test_HS_DE-IT_output.txt -ofh  test_HS_DE-IT_output.txt.html -tc HS_DE-IT_topic.txt -type p -xslt -u  seed_suva.txt -cfg FBC_config.xml</code></pre>

h2. Example of java code

<pre>

<code class="java">

package gr.ilsp.fmc.classifier;

public enum ClassifierCounters {

    CLASSIFIER_DOCUMENTS_PASSED,   // successfully classified a document.

    CLASSIFIER_DOCUMENTS_FAILED,   // failed to classify a document

    CLASSIFIER_DOCUMENTS_ABORTED, 

    CLASSIFIER_TIME

}</code></pre>
