Abstract: "The InfoCrystal$\sp{\rm TM}$ is a novel representation that uses a simple visual metaphor to help users deal with some of the complexities inherent in information retrieval. As a visualization tool, it can display all the possible binary as well as continuous relationships among N concepts. As a visual query language, the InfoCrystal enables users to formulate both Boolean and vector space queries graphically. Hence, it provides a visual framework that unifies the complementary Boolean and Partial Matching approaches and allows users to take advantage of their respective strengths. The InfoCrystal acts like a Boolean Calculator and users can use it to employ the expressive power of the Boolean retrieval approach and its broadening/narrowing techniques in a visual way. Further, users can assign relevance weights to the concepts and formulate weighted queries by interacting with a threshold slider. The InfoCrystal offers the added advantage that users can control in a visual way how to translate weighted queries into Boolean queries. Finally, arbitrarily complex queries can be created by using the InfoCrystals as building blocks and organizing them in a hierarchical structure. |
