Relevance Clues: Development and empirical examination of a model for relevance decisions on search results based on individual user criteria
In today’s knowledge-based society, people regularly search for information in digital information systems. They decide whether a search result is helpful to solve their search task or not based on diverse and highly subjective criteria. The purpose of this research project is to determine subjective criteria as well as the interdependence between different criteria on individual relevance decisions regarding search results in an academic context. Dependable results will be achieved by applying an experimental research design involving human test persons – an approach still rarely used in Information Science – and by building a sample large enough for statistically firm statements.
Project results so far include a user model for relevance assessments in academic search systems taking into account popularity data, e.g., citation or download frequencies of the particular work. The model aims at a systematic representation of elements of a search result as potential relevance clues, subjective relevance criteria users apply when assessing the results, and contextual relevance factors as variables influencing relevance judgments. Furthermore, a methodological framework for incorporating popularity data in experimental studies on relevance criteria has been developed.
