This paper discusses the approach to multiword expressions being adopted in the LinGO English Resource Grammar (http://lingo.stanford.edu), a broad-scale bidirectional grammar of English in the HPSG framework. We discuss how the lexicon of multiword expressions is encoded in a database and describe the implications for building a reusable lexical resource.

We present several significant improvements in the implementation of the quick check pre-unification filter [7] [10], and the potential way in which the design of the quick check [15] [17] can be further extended. We analyse the effect of these extensions on LinGO, the large-scale HPSG grammar for English[14]. Althought these developments were done for the compiler system LIGHT [8], most of the...

We consider the effect of the underlying logical structure on the asymptotic behavior of space-time diagrams of elementary Boolean cellular automata by focussing on the important case of Rule 110 and its counterparts under various many-valued logics. In particular we show that for a (continuous) probabilistic logic the corresponding rule, dubbed PCA 110, appears to have space-time diagrams with...

In this paper we investigate the phenomenon of phrasal verbs, discussing their characteristics and the challenges that they present for possible treatments. We also discuss the treatment for phrasal verbs in a particular grammar, the LinGO-ERG, and the coverage it provides. Possible ways of extending the coverage of this grammar are analysed and proposed, taking into account the regular pattern...
