	abstract = {It is common to classify data in hierarchies, they provide a comprehensible way of understanding big amounts of data. From budgets to organizational charts or even the stock market, trees are everywhere and people find them easy to use. However when analysts need to compare two versions of the same tree structure, or two related taxonomies, the task is not so easy. Much work has been done on this topic, but almost all of it has been restricted to either compare the trees by topology, or by the node attribute values. With this project we are proposing TreeVersity, a framework for comparing tree structures, both by structural changes and by differences in the node attributes. This paper is based on our previous work on comparing traffic agencies using LifeFlow [1, 2] and on a first prototype of TreeVersity.},

	abstract = {We describe a theoretical investigation into the semantic space described by our interlingua (IL), which currently has 191 main verb classes divided into 434 subclasses. represented by 237 distinct Lexical Conceptual Structures (LCSs). Using the model of aspect in Olsen (1994b, 1997a) monotonic aspectual composition we have identified 71 aspectually basic subclasses that are associated with one or more of 68 aspectually non-basic classes via some lexical ("type-shifting") rule (Bresnan 1982, Pinker 1984, Levin and Rappaport Hovav 1995). This allows us to refine the IL and address certain computational and theoretical issues at the same time. From a linguistic viewpoint, the expected benefits include a refinement of the aspectual model in (Olsen :1994b, 1997a) (which provides necessary but not sufficient conditions for aspectual composition), and a refinement of the verb classifications in (Levin 1993); we also expect our approach to eventually produce a systematic definition (in terms of LCSs and compositional operations) of the precise meaning components responsible for Levin{\textquoteright}s classification. Computationally, the lexicon is made more compact.},
