Abstract
This paper presents a text mining methodology to extract outlying knowledge
from a collection of financial statements. The main idea is to extract relevant
financial performance indicators and discover implicit textual description of the
indicators. The extracted information was represented using a network language
i.e. conceptual graph. Outlier mining was performed on the conceptual graph
representation using a deviation based method. Experiments were carried out to
evaluate the effectiveness of the proposed method. Results show that the
proposed method is able to excerpt outlying knowledge from the financial
statements with accuracy comparable to human experts.
Keywords: text mining, information extraction, conceptual graphs, outlier
mining in text, deviation based outlier mining method.
Keywords
