| Summary: | Abstract— Topic identification is a crucial task
for discovering knowledge from textual document.
Existing methods for topic identification suffer
from word counting problem as they depend on the most frequent terms in the text to produce the
topic keyword.Not all frequent terms are relevant.
This paper proposes a topic identification method
that filters the important terms from the preprocessed text and applied term weighting
scheme to solve synonym problem.A rule generation algorithm is used to determine the appropriate topics based on the weighted terms.The text document used in the experiment is the English translated Quran.The topics identified from the proposed method were compared with topics identified using Rough Set and domain experts. From the findings, the proposed topic identification method was consistently able to
identify topics that are mostly close to the topics that have been given by Rough Set and the
experts.The result from the comparison proved
that the proposed method was able to be used to
capture topics for textual documents. |
