When different fields use different terms for the same idea, start by identifying all the variant terms through a comprehensive synonym search across disciplines, then use Boolean operators to capture them in a single query.
Map the Terminology Landscape
Begin by consulting review papers or handbooks in each relevant field to understand how they frame the concept. For example, what computer scientists call "feature extraction" might be termed "variable selection" in statistics or "dimensionality reduction" in machine learning. Create a master list of synonyms, related terms, and field-specific jargon.
Check specialized dictionaries and thesauri for your disciplines. The MeSH (Medical Subject Headings) database is invaluable for biomedical research, while IEEE and ACM taxonomies help with engineering and computing terminology.
Build an Inclusive Search Strategy
Construct your search query using OR operators to capture all variants: ("feature extraction" OR "variable selection" OR "dimensionality reduction"). This ensures you're not missing critical literature simply because authors used different vocabulary.
For complex cross-disciplinary searches, WisPaper's Deep Search understands this kind of multi-term logic and filters out irrelevant results that match your keywords but miss your intent—particularly useful when the same term means different things in different contexts (like "cell" in biology versus battery research).
Create a Translation Key
As you read, maintain a terminology mapping document. Note which fields prefer which terms and whether there are subtle conceptual differences. Sometimes apparent synonyms actually represent slightly different approaches or assumptions, and recognizing these distinctions strengthens your literature review.
Leverage Cross-Disciplinary Reviews
Look for integrative review papers that explicitly bridge terminological gaps. These often include helpful tables mapping equivalent terms across fields and can save you significant time in understanding how different communities conceptualize the same phenomena.
When writing your own work, acknowledge the terminology variation in your introduction or methods section. This demonstrates methodological rigor and helps readers from different backgrounds understand your approach. Consider using the most widely recognized term as your primary label while noting alternatives in parentheses on first use.
