A linguistically driven framework for query expansion via grammatical constituent highlighting and role-based concept weighting
作者：
Highlights：
•
• Linguistically-motivated query expansion framework.
• Classification of query constituents within four concept types: descriptive, relational, structural and concepts-of-interest.
• Algorithm capitalizing on syntactical dependencies to capture relationships between adjacent and non-adjacent query concepts.
• Weighting scheme emphasizing the importance of query constituents based on their linguistic role.
