<abstract>In automated scientific document analysis, accurately interpreting math formulae is imperative alongside comprehending natural language. Ambiguity in math identifiers within a single document poses significant challenges to understanding math formulae. While disambiguating math identifiers across documents has seen some progress, resolving ambiguity within a document remains inadequately researched due to complexity and insufficient datasets. The level of difficulty and information required to accomplish this task was uncertain. This study aims to determine which information is necessary for the intra-document disambiguation of math identifiers. Our findings indicate that the position data and local formula structure surrounding the identifiers, including modifiers, are particularly critical. For our study, we expanded a dataset for formula grounding and doubled its size to include annotations for 27,655 math identifier occurrences.
