This repository contains accompanying material to our short paper submitted and accepted at the CLEF2017 conference.

You can find the paper in the official CLEF2017 conference proceedings, or at the arXiv.

Getting Started

To get a copy of the materials, use either git clone, or download the repository's content as a compressed file (.zip) and extract it anywhere on your local file system.

Prerequisites

Currently, OXPath is only supported on 64bit Linux-based operating systems. Java has to be installed on this system (version 8 or above). Optionally, the xvfb package has to be installed if you want to use the option to run Firefox in the X virtual framebuffer for the evaluation of OXPath expressions.

Installation of XVFB (e.g. on Ubuntu 16.04)

$ sudo apt install xvfb

Get OXPath

OXPath can be obtained from: www.oxpath.org/download

Pick the latest version of the CLI jar and save it to a convenient location.

Running the example

With OXPath 2.0

To run the example, fire up a command line where you extracted/cloned this repository to, and input the following command, where

• -query script/sowiport_solis_en.oxp: reads the OXPath expression in the file sowiport_solis_en.oxp in the script subfolder
• -logfile VerboseLog4j.properties: uses the provided custom logging configuration file for more verbose logging (recommended for OXPath beginners)
• -browser firefox_xvfb: runs the OXPath evaluation with a virtual frame buffer
• -output output/sowiport_solis_en.xml: re-directs the XML output to the file sowiport_solis_en.xml in the subfolder output
• -xml: sets the output format to XML

$ java -jar oxpath-2.0-cli.jar -query script/sowiport_solis_de.oxp -logfile VerboseLog4j.properties -browser firefox_xvfb -output output/sowiport_solis_de.xml -xml

Hint: If your system is localized to German language, use sowiport_solis_de version of the script. Else, use the sowiport_solis_en version.

With OXPath 2.0.2
