Which one is better: presentation-based or content-based math search?
This work addresses the problem of retrieving mathematical content more effectively for users in fields like education or research, though it appears incremental as it builds on existing search systems.
The paper compared presentation-based and content-based strategies for searching math expressions, finding that content-based search, which uses semantic enrichment to consider meaning, improves search quality over presentation-based systems.
Mathematical content is a valuable information source and retrieving this content has become an important issue. This paper compares two searching strategies for math expressions: presentation-based and content-based approaches. Presentation-based search uses state-of-the-art math search system while content-based search uses semantic enrichment of math expressions to convert math expressions into their content forms and searching is done using these content-based expressions. By considering the meaning of math expressions, the quality of search system is improved over presentation-based systems.
