Abstract
This study investigated the influences of structured query on retrieval performance from textual, linguistic, and fielded characteristics. The search runs of NCTIR-6 CLIR Task have been used as the targeted data for this study. The results concluded that only subject out of other textual characteristics demonstrated significant effects on retrieval performance; linguistic characteristics showed great impacts on retrieval performance; fielded information did not show significant effects on retrieval performance but some fielded information performed better than others. This study also made clear that there existed interactions between fielded information in queries and participating teams (consequently the retrieval techniques used by these teams) but no significant interactions between linguistic characteristics and participating teams.
