The Abject Failure of Keyword IR for Mathematics Search: Berkeley at NTCIR-10 Math.
Ray R. Larson, Chloe Reynolds, Fredric C. Gey · NTCIR · 2013
This paper demonstrates that classical content search using individual keywords is inadequate for mathematical formulae search. For the NTCIR10 Math Pilot Task, the authors used a standard indexing by content word for search coupled with search for components of mathematical formulae. This was followed by formula extraction from the top ranked documents. Performance was terrible, even for partial relevance. The further inclusion of some manual reformulation of topics into queries did not improve retrieval performance.
