Abstract: Described systems and methods allow a computer system to employ a lexicon network for word sense disambiguation (WSD). In an exemplary embodiment, each node of the lexicon network represents a gloss of a lexicon entry, while an edge represents a lexical definition relationship between two glosses. The lexicon network is ordered prior to WSD, wherein ordering the lexicon network comprises arranging the nodes of the lexicon network in an ordered sequence, and removing a set of edges to eliminate loops. In some embodiments, the position of each node within the ordered sequence is determined according to a direction and a weight of an edge connected to the respective node. The weight may represent a semantic importance of the respective edge relative to other edges of the network.

Abstract: In some embodiments, linguistic knowledge bases including multiword lexicon entries belonging to various natural languages are generated and maintained. Multiword lexicon entries include representations of multiword expressions (e.g. composite words such as “expectation value”, verbal phrases such as “to stumble upon”, and idiomatic phrases such as “to hit the nail on the head”), and multiword inflection templates (e.g. “more adjective” as a symbolic representation for the comparative form of adjectives). A representation of a multiword lexicon entry, including a dependency tree and/or an attribute-value tree, is displayed within a graphical user interface, allowing a user to verify, update, and correct lexical data. Computer-readable encodings (e.g. XML) of dependency tree and/or attribute-value tree data are saved as part of each lexicon entry.
