This paper proposes an unsupervised approach to automatically interpret noun compounds using semantic similarity. Our proposed unsupervised method is based on obtaining a large amount of robust evidence for NC interpretation. In order to obtain evidence sentences for semantic relations (SRs), we first acquired sentences containing both a head noun and its modifier in the form of SR definitions. Then we determined the semantic relations represented in the sentences by looking at the nouns in the test instances (noun mapping) and verbs in the SR definitions (verb mapping). In the noun mapping, we measured the similarity between nouns in test instances and nouns in the collected sentences. In the verb mapping, we mapped the verbs ofsentences onto those in the SR definitions. Finally, we built a statistical classifier to interpret noun compounds and evaluated it over 17 SRs defined in [1].

A software control system for an autonomous mobile robot must be capable of performing many complex processing tasks in real time. Such tasks may include localising within the environment, recognising objects or safely avoiding static and dynamic obstacles. The focus for our team this year was to build a solid structural base, to be used in future RoboCup competitions. This led us to concentrate on development of effective reusable components such as a robust vision system. The RoboMutts team was a joint venture between the University of Melbourne and RMIT University. This paper focuses on the parts of the system developed at the University of Melbourne.

The difficulty of writing, reading, and understanding formal specifications is one of the main obstacles in adopting formal verification techniques such as model checking and runtime verification. Introducing concepts in formal methods in an undergraduate program is essential for training a workforce that can develop and test high-assurance systems. This paper presents educational outcomes and outlines an instructive component that can be used in an undergraduate course to teach formal approaches and languages. The component uses a model checker and a specification tool to teach Linear Temporal Logic (LTL), a specification language that is widely used in a variety of verification tools. The paper also introduces a novel technique that analyzes LTL specifications by using the SPIN model checker to elucidate the behaviors accepted by the specifications.

In this paper, we propose a partially lexicalized parsing model utilizing rich features to improve the parsing ability and reduce the parsing cost. In order to disambiguate parse trees effectively, it employs several useful features such as a syntactic label feature, a content feature, a functional feature, and a size feature. Besides, it is partially lexicalized so as to reduce the parsing cost closely connected with lexical information. Moreover, it is designed to be suitable for representing word order variation and constituent ellipsis in Korean sentences. Experimental results show that the proposed parsing model using more features performs better although it less depends on lexical information.
