Ontology and Lexical Semantics for Generating Temporal Discourse Markers
نویسنده
چکیده
In text, temporal relations between events can be signalled in several ways; among them are speciic lexical items, here called temporal discourse markers. We analyse the semantics of about 20 German subordinating conjunctions and prepositions and transfer these ndings to a sentence generation framework that uses a dedicated discourse marker lexicon for producing complex sentences. After discussing the ontological decisions and the lexical representations, we demonstrate how this information can be used to choose an appropriate temporal marker when verbalizing a pair of time-stamped event representations.

The role of Persian causative markers in the acquisition of English causative verbs
This project investigates the relationship between lexical semantics and causative morphology in the acquisition of causative/inchoative-related verbs in English as a foreign language by Iranian speakers. Results of translation and picture judgment task show although L2 learners have largely acquired the correct lexico-syntactic classification of verbs in English, they were constrained by ...
متن کاملTemporal anaphora across and inside sentences: The function of participles
The paper offers a formal account of the discourse behaviour of participles, which to some extent behave like main clauses in having semantically undetermined relations to their matrix clause, but which should nevertheless be integrated into the compositional semantics of complex sentences. The theory is developed on the basis of Ancient Greek participles and offers an account of their syntax, ...
متن کاملAn Interface between Lexical and Discourse Semantics. The case of the light verb "have"
The macro-target of discourse interpretation for computational purposes is the automatic detection of events in a text and their ordering in a temporal scale. Asher and Lascarides’ (2003) ideas on the semantics-pragmatics interface between the lexical and discourse level along with the logic mechanism for inferring rhetorical structure (often nonmonotonically) proposes an interesting way of ach...

We propose a robust answer reranking model for non-factoid questions that integrates lexical semantics with discourse information, driven by two representations of discourse: a shallow representation centered around discourse markers, and a deep one based on Rhetorical Structure Theory. We evaluate the proposed model on two corpora from different genres and domains: one from Yahoo! Answers and ...
متن کاملLexical Cohesion in Linguistic and Musical Discourse
An analogy is presented between music and linguistic discourse in terms of lexical cohesion. Linguistic discourse and music are two different manifestations of human communication. They are both meaningful and coherent, and both are processes inherently temporal. Lexical cohesion is a semantic relation manifested in the lexical level of language. A short sample of discourse is analysed and comp...
