Time Expressions Ontology for Information Seeking Dialogues in the Public Transport Domain
Conference paper
Abstract
The paper presents an ontology of natural language temporal expressions which occur in dialogues led by users of a public transport call center. It was elaborated on the basis of analysis of 500 transliterated dialogues and contains a multihierarchy of concepts representing semantics of time referring fragments of interlocutors’ utterances. The paper contains also an analysis of frequencies of all types of time relevant expressions within the analyzed data.
