Query Formulation for Answer Projection
[chapter]
2005
Lecture Notes in Computer Science
Preserved Fulltext
We examine the effects of various query modifications on the problem of answer projection -the task of retrieving documents that support a given answer to a question. ...
We compare different techniques such as phrase searches and term weighting, and show that some models achieve significant improvements over unmodified queries. ...
Conclusions We address the answer projection task in Question Answering as a query formulation problem. ...

The system provides different options, including visual, to formulate queries over ontologies and to display query answers. ...
Moreover, the system offers highly optimised techniques for query answering. ...
For the query formulation we will stress our visual query formulation tool that currently supports construction of tree-shaped conjunctive SPARQL queries. ...

First, the occurrence of multiple linguistic formulations of the same answer increases the chances of being able to find an answer that occurs within the context of a simple pattern matching the query. ...
Answer Redundancy and Question Answering Answer redundancy (multiple, differently phrased, answer occurrences) serves two purposes for our task of question answering. ...
We believe that data redundancy is a readily available and valuable resource that should be exploited for question answering in much the same way as linguistic resources often are. ...
