The MCAT Math Retrieval System for NTCIR-10 Math Track
NTCIR Math Track targets mathematical content access based on both natural language text and mathematical formulae. This research describes the participation of MCAT group in the NTCIR math retrieval subtask and math understanding subtask. We introduce our mathematical search system that is capable of formula search, and full-text search. We also introduce our mathematical description extractio...
متن کاملMCAT Math Retrieval System for NTCIR-12 MathIR Task
This paper describes the participation of our MCAT search system in the NTCIR-12 MathIR Task. We introduce three granularity levels of textual information, new approach for generating dependency graph of math expressions, score normalization, cold-start weights, and unification. We find that these modules, except the cold-start weights, have a very good impact on the search performance of our s...
متن کاملICST Math Retrieval System for NTCIR-11 Math-2 Task
In NTCIR-11, the NTCIR-Math-2 Task is organized for mathematical information retrieval. This paper proposes an innovative system for efficient formula index and retrieval. We build a novel indexing and matching model, taking both textual and spatial similarities into consideration. Besides, a hierarchical technique is introduced to generate sub-trees from the semi-operator trees of formulae. Th...
