An introduction to information security evaluation

Abstract

In recent years, analysts have been confronted with the in- creasing availability of on-line sources of information in the form of natural-language texts. This increased accessibility of textual information has led to a corresponding interest in technology for processing this text automatically to extract task-relevant information. This demand for a technological solution to the need to deal with the often-overwhelming quantity of available information has stimulated the devel- opment of the field of Information Extraction. This article provides an overview of the problems addressed, current ap- proaches toward solutions, and assesses the state of the art and its potential for future progress.
