Paper Abstract:
|
One of the main handicaps in research on automatic summarization is the vague semantic comprehension of the source,
which is reflected in the poor quality of the consequent summaries. Using further knowledge, as that provided by
ontologies, to construct a complex semantic representation of the text, can considerably alleviate the problem.
In this paper, we introduce an ontology-based extractive method for summarization. It is based on mapping the text to
concepts and representing the document and its sentences as graphs. We have applied our approach to news articles,
taking advantages of free resources such as WordNet. Preliminary empirical results are presented and pending problems
are identified. |
