On document evaluation for better context-aware summary generation

摘要

Improving the quality of summaries created for the documents explored during informational search is the essential point in the interpretation of search engine results. In many cases summaries generated by the search engines are not indicative enough, therefore the user cannot quickly judge about the document relevancy. Having the WordNet ontology based weighting procedure proposed in earlier works as a starting point, the improved metric for better summary generation is introduced. This evaluation approach takes into account not only ontologically related weights for each term in the query, but also the relative distribution of terms regarding to their relevance to the document paragraphs.
