概要	Information Horizons Mapping is a research method developed by Diane Sonnenwald and colleagues, formalized in their 2001 paper in The New Review of Information Behaviour Research, for studying how people seek information within a specific context. Grounded in Sonnenwald's theory of information horizons — the idea that, in any given situation, an individual perceives a 'horizon' of information resources (people, documents, tools, systems) that they may consult — the method asks participants to draw a map of those sources for a particular information need and to explain it. By analyzing which sources appear, how close or central they are placed, how they relate to one another, and why some are included or excluded, researchers gain a situated, participant-centered picture of information-seeking behaviour that goes beyond simple source-use surveys.	Sense-Making Methodology, developed by Brenda Dervin from the 1970s onward and synthesized in her 1998 overview, is a theory and method for studying how people construct meaning as they move through life and are repeatedly stopped by gaps in their understanding. Its central metaphor pictures a person moving through time-space, halted at a moment of discontinuity (a gap), and building a bridge across it by seeking and using information. Rather than classifying users by demographic traits, Sense-Making asks what situation a person was in, what gap or question they faced, and what help or use they sought — the situation-gap-use triad — elicited through the distinctive Time-Line and Micro-Moment interview. The approach reframes information not as an objective thing transmitted but as a construction people make sense of in context.
