ASIUM is a system based on clustering and cooperative methods.
ASIUM takes as input the syntactic analysis of sentences such that the phrases are identified and for each noun phrase the preposition if any and the head word IS given.
ASIUM learns an ontology for texts given as input and a set of case frames where the semantic features are filled by ontology concepts.
The method is based on conceptual and hierarchical clustering. Basic clusters are formed by words that occur with the same verb after the same preposition (or the same function, if there is no preposition). A distance is computed between all basic clusters. New clusters are formed by gathering the closest clusters. The hierachy of clusters form the ontology. Case frames are learned in parallel, so that each time a concept is formed, it fills the corresponding semantic feature in the case frame.
The graphic interface of ASIUM allows the user to inspect, validate and refine the knowledge learned at each step of the learning process.
