Paper Abstract:
|
Conventional keyword-based indexing and retrieval techniques for textual documents lack of precision when a long
query string is employed in order to discover documents containing a specific event, such as Einstein discovered
relativity. This paper proposes a framework to resolve such a problem. In our proposal, we apply semantic role labeling
and coreference techniques in order to parse each sentence within textual documents into three elements: subject, object
and predicates. These elements can subsequently be used for indexing and retrieval. Our primitive evaluation experiments
have shown that this promising methodology raises the retrieval precision if we compared it to conventional literal termmatching
techniques. |
