Cue-Based Interpretation of Customer's Requests: Analysis of Estonian Dialogue Corpus

摘要

Estonian spoken human-human information dialogues (calls) have been analyzed with the aim of finding lexical and syntactic cues which can be used for automatic recognition of dialogue acts. We considered a customer's requests where the goal of the speaker is to get some information or trigger an action by the hearer who is an official person. The corpus analysis demonstrates that a limited number of verbs in a limited number of forms are used to form requests, and there is a difference between general requests which only introduce a topic and exact requests where the speaker has to get certain information or trigger an action by the hearer.
