Recent studies on the analysis of intonational function examine a r a n ~ of materials from cue phrases in monologue (Litman and Hirschberg, 1990) and dialogue (Hirschberg and Litman, 1987; Hockey, 1991) to longer utterances in both monologue and dialogue (McLemore, 1991). Results match specific intonational tunes to certain discourse functions which are more or less well defined. Although thes...

Prepositional Phrase is the key issue in structural ambiguity. Recently, researches in corpora provide the lexical cue of prepositions with other words and the information could be used to partly resolve ambiguity resulted from prepositional phrases. Two possible attachments are considered in the literature: either noun attachment or verb attachment. In this paper, we consider the problem from ...

My central goal is to compute dialogue acts automatically. A dialogue act is a concise abstraction of a speaker’s intention, such as SUGGEST and REQUEST. Recognizing dialogue acts is critical to understanding at the discourse level, and dialogue acts can also be useful for other applications, such as resolving ambiguity in speech recognition. But, often, a dialogue act cannot be directly inferr...

Automatic paraphrase discovery is an important but challenging task. We propose an unsupervised method to discover paraphrases from a large untagged corpus, without requiring any seed phrase or other cue. We focus on phrases which connect two Named Entities (NEs), and proceed in two stages. The first stage identifies a keyword in each phrase and joins phrases with the same keyword into sets. Th...

This research was an attempt to find the relationship between English discourse markers and their Farsi translations. It was conducted in order to find out whether DMs translations completely demonstrate source texts orientation and to what extent DMs translations are functionally appropriate compared to the original text? Six instruments were used. Three of them were the original English books...

Research on ad copy design is well-studied in the context of offline marketing. However, researchers have only recently started to investigate ad copies in the context of paid search, and have not yet explored the potential of information cues to enhance customers’ search process. In this paper we analyze the impact of an information cue on user behavior in ad copies. Contrary to prevalent advi...

The notion that a text is coherent in virtue of the `relations' that hold between its component spans currently forms the basis for an active research programme in discourse linguistics. Coherence relations feature prominently in many theories of discourse structure, and have recently been used with considerable success in text generation systems. However, while the concept of coherence relatio...

We present recent work in the area of Cross-Domain Dialogue Act tagging. Our experiments investigate the use of a simple dialogue act classifier based on purely intra-utterance features principally involving word n-gram cue phrases. We apply automatically extracted cues from one corpus to a new annotated data set, to determine the portability and generality of the cues we learn. We show that ou...
