"A Link Analysis Tool: Visualising Entities and Relations Extracted from Text"

Supervised by R.Gaizauskas

Abstract

Using the output of the Natural Language Processing Group's information extraction system within the Department of Computer Science, University of Sheffield, this project produces a visualisation tool that will support link analysis using information extracted from the on-line news sources. The visualization tool enables key information from across a range of news sources to be seen "at a glance". The tool is intended for users who desire readable results from information extraction and so meets high HCI standards. The project incorporates a standard software development process including specification, design and implementation and testing phases, and an adequate visualization tool is produced to meet these requirements following an investigation into the background of Information extraction and the techniques that may be employed to develop such a visualization tool.
