| Abstract | With the recent explosive growth of the Internet resources, users are tending to seek information
from a digital libra1y across national boundaries. The ability to query large multilingual
collections using a single language could be beneficial. Multilingual Information Retrieval
(MIR) is used to take queries in one language and retrieve relevant documents written in other
languages. It has been found that the current MIR system leads to a drop in effectiveness of 40-
60% of monolingual retrieval. Hence, it is necessary to find a way to improve the performance
of translation and searching in MIR services.
In this research, a system model of MIR is proposed by using interactive query formulation
under Resource Description Framework (RDF). The user query is structured in the same way as
the resource description and then formulated according to the knowledge base and basic
grammar rules assisted by user interaction. The system adopts dictionary and corpora for initial
translations of the user query, and then interacts with user to reduce the ambiguities of such
translations. This approach provides more effective results for query translations and also
provides more information for retrieval as the Internet resources are described in the same
structure.
For the above theoretical system model, a simplified application system is implemented to
achieve and simulate part of abilities. It is an application mainly used in Internet and
implemented in Java, Java Servlet, and metadata database under RDF as simulant collections. |
