We propose a visualization concept that incorporates a sentiment analysis of aspects mentioned in examined documents. Our concept provides a means of iteratively refining the query based upon preliminary search results. After an abstract description of the concept, we elaborate on its usage in a practical example of filtering customer reviews in order to choose a restaurant based on user-defined preferences.enAspect grid: A visualization for iteratively refining aspect-based queries on document collectionsText/Conference Paper1617-5468
