To this end, we use a maximum entropy model to automatically detect action item-related utterances from multi-party audio meeting recordings. We compare the effect of lexical, temporal, syntactic, semantic, and prosodic features on system performance. We show that on a corpus of action item annotations on the ICSI meeting recordings, characterized by high imbalance and low inter-annotator agreement, the system performs at an F measure of 31.92%. While this is low compared to better-studied tasks on more mature corpora, the relative usefulness of the features towards this task is indicative of their usefulness on more consistent annotations, as well as to related tasks.","PeriodicalId":426429,"journal":{"name":"SIGDIAL Workshop","volume":"1663 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126895191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Adjacency pair theory has widespread acceptance, but traditional classification features (in particular, 'previous-tag' type features) do not exploit this information optimally. We suggest a method of dialogue segmentation that verifies adjacency pairs and allows us to use dialogue-level information within the entire segment and not just the previous utterance. We also use the X2 test for statistical significance as 'noise reduction' to refine a list of pairs. Together, these methods can be used to extend expectation beyond the traditional classification features.","PeriodicalId":426429,"journal":{"name":"SIGDIAL Workshop","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129229207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In selecting the best model, our formalism balances conflicting factors: model complexity against data fit, and structure complexity against belief reasonableness. We first describe our basic formalism, which considers interpretations comprising inferential relations, and then show how our formalism is extended to suppositions that account for the beliefs in an argument, and justifications that account for the inferences in an interpretation. Our evaluations with users show that the interpretations produced by our system are acceptable, and that there is strong support for the postulated suppositions and justifications.","PeriodicalId":426429,"journal":{"name":"SIGDIAL Workshop","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120969768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this task, a typical and often implicit assumption in previous studies is that a document has just one topic and therefore many algorithms have been tested and have shown encouraging results on artificial data sets, generated by putting together parts of different documents. We show that evaluation on synthetic data is potentially misleading and fails to give an accurate evaluation of the performance on real data. Moreover, we provide a critical review of existing evaluation metrics in the literature and we propose an improved evaluation metric.","PeriodicalId":426429,"journal":{"name":"SIGDIAL Workshop","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123191250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Within a dimension or a layer, subsets of tags are often hierarchically organised. We argue that especially for such highly structured annotation schemes the well-known kappa statistic is not an adequate measure of inter-annotator agreement. Instead, we propose a statistic that takes the structural properties of the tagset into account, and we discuss the application of this statistic in an annotation experiment. The experiment shows promising agreement scores for most dimensions in the tagset and provides useful insights into the usability of the annotation scheme, but also indicates that several additional factors influence annotator agreement. We finally suggest that the proposed approach for measuring agreement per dimension can be a good basis for measuring annotator agreement over the dimensions of a multidimensional annotation scheme.","PeriodicalId":426429,"journal":{"name":"SIGDIAL Workshop","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126841369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
