Which one is better: presentation-based or content-based math search?

TL;DR

This paper compares presentation-based and content-based math search methods, showing that semantic enrichment of math expressions enhances search quality by considering their meaning.

Contribution

It introduces a content-based approach using semantic enrichment and compares its effectiveness against traditional presentation-based search.

Findings

Content-based search improves accuracy over presentation-based methods.

Semantic enrichment enhances the understanding of math expressions.

The proposed approach yields better search relevance.

Abstract

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.
