Dear DSpace community, we are a group of computer science researchers that are considering to use DSpace for our project http://indianamas.disi.unige.it/.
Our digital objects are images that should be classified according to some categories from a controlled vocabulary (human_being, animal, car, ...). Each image can be associated with more than one concept from the controlleed vocabulary, and each classification may have a confidence in [0%, 100%]. For example, image1 could be classified as an animal with confidence 76% and as a car with confidence 20%. We would like to store this information (multiple classifications, each with a confidence) in a structured way in order to make searches like "Give me all the images that have been classified as cars with a confidence > 45%". According to our preliminary tests, we feel this problem cannot be solved with the element.qualifier structure, since the couples (animal, 76) and (car, 20) referring to image1 are divided into element.classification = car; element.classification = animal; element.confidence = 20; element.confidence = 76; but nothing says that the confidence "76" refers to the classification "animal". We would avoid to solve the problem with a string that encodes the couples, like in the following lines element.classification_and_conf = "(car;20)" element.classification_and_conf = "(animal;76)" as making queries would become very complex and expensive: a query like "Give me all the images that have been classified as cars with a confidence > 45%" would require a parsing of the string that cannot be solved with the standard "Equals"and "Contains" query filters.
