    1. Finding the Best Picture: Cross-Media Retrieval of Content

      We query the pictures of Yahoo! News for persons and objects by using the accompanying news captions as an indexing annotation. Our aim is to find these pictures on top of the answer list in which the sought persons or objects are most prominently present. We demonstrate that an appearance or content model based on syntactic, semantic and discourse analysis of the short news text is only useful for finding the best picture of a person of object if the database contains photos each picturing many entities. In other circumstances a simpler bag-of-nouns representation has a good performance. The appearance ...

    2. A case study of gesture expressivity breaks

      Abstract  In this paper we propose a study of co-verbal gesture expressivity during a conversational interaction. The work is based on the analysis of gesture expressivity over time, that we have conducted on two clips of 2D animations. The first results point out two types of modulations in gesture expressivity that we relate to the rhetorical functions of the discourse. These results extend the knowledge about gesture expressivity from emotion and personality issues to pragmatical ones. An evaluation study is proposed to measure the effects of the modulations.

    3. Chinese Abbreviation-Definition Identification: A Svm Approach Using Context Information

      As a special form of unknown words, Chinese abbreviations represent significant problems for Chinese text processing. The goal of this study is to automatically find the definition for a Chinese abbreviation in the context where both the abbreviation and its definition occur, enforcing the constraint of one sense per discourse for an abbreviation. First, the candidate abbreviation-definition pairs are collected, and then a SVM approach using context information is employed to classify candidate abbreviation-definition pairs so that the pairs can be identified. The performance of the approach is evaluated on a manually annotated test corpus, and is also compared with ...

    4. Meeting Structure Annotation

      We describe a generic set of tools for representing, annotating, and analysing multi-party discourse, including: an ontology of multimodal discourse, a programming interface for that ontology, and NOMOS – a flexible and extensible toolkit for browsing and annotating discourse.We describe applications built using the NOMOS framework to facilitate a real annotation task, as well as for visualising and adjusting features for machine learning tasks. We then present a set of hierarchical topic segmentations and action item subdialogues collected over 56 meetings from the ICSI and ISL meeting corpora using our tools. These annotations are designed to support research towards automatic ...

    5. Sense Annotation in the Penn Discourse Treebank

      An important aspect of discourse understanding and generation involves the recognition and processing of discourse relations. These are conveyed by discourse connectives, i.e., lexical items like because and as a result or implicit connectives expressing an inferred discourse relation. The Penn Discourse TreeBank (PDTB) provides annotations of the argument structure, attribution and semantics of discourse connectives. In this paper, we provide the rationale of the tagset, detailed descriptions of the senses with corpus examples, simple semantic definitions of each type of sense tags as well as informal descriptions of the inferences allowed at each level.

    6. Keyphrase Extraction in Scientific Publications

      We present a keyphrase extraction algorithm for scientific publications. Different from previous work, we introduce features that capture the positions of phrases in document with respect to logical sections found in scientific discourse. We also introduce features that capture salient morphological phenomena found in scientific keyphrases, such as whether a candidate keyphrase is an acronyms or uses specific terminologically productive suffixes. We have implemented these features on top of a baseline feature set used by Kea [1]. In our evaluation using a corpus of 120 scientific publications multiply annotated for keyphrases, our system significantly outperformed Kea at the p  Content ...

    7. Processing of inconsistent emotional information: an fMRI study.

      Processing of inconsistent emotional information: an fMRI study. Exp Brain Res. 2007 Dec 20; Authors: Rota G, Veit R, Nardo D, Weiskopf N, Birbaumer N, Dogil G Previous studies investigating the anterior cingulate cortex (ACC) have relied on a number of tasks which involved cognitive control and attentional demands. In this fMRI study, we tested the model that ACC functions as an attentional network in the processing of language. We employed a paradigm that requires the processing of concurrent linguistic information predicting that the cognitive costs imposed by competing trials would engender the activation of ACC. Subjects were confronted with ...

    8. Using discourse analysis to improve text categorization in Medline.

      Related Articles Using discourse analysis to improve text categorization in MEDLINE. Medinfo. 2007;12(Pt 1):710-5 Authors: Ruch P, Geissbühler A, Gobeill J, Lisacek F, Tbahriti I, Veuthey AL, Aronson AR PROBLEM: Automatic keyword assignment has been largely studied in medical informatics in the context of the MEDLINE database, both for helping search in MEDLINE and in order to provide an indicative "gist" of the content of an article. Automatic assignment of Medical Subject Headings (MeSH), which is formally an automatic text categorization task, has been proposed using different methods or combination of methods, including machine learning (na ...

    9. Automatic Evaluation of Text Coherence: Models and Representations

      This paper investigates the automatic evaluation of text coherence for machine-generated texts. We introduce a fully-automatic, linguistically rich model of local coherence that correlates with human judgments. The modeling approach taken relies on shallow text properties and is relatively inexpensive. We present experimental results that comparatively assess the predictive power of various discourse representations prop...

    11. Systems and method for resolving ambiguity

      Techniques are provided for resolving ambiguity in natural language speech. Speech is recognized using automatic speech recognition. A theory of discourse analysis is determined and at least one set of candidate discourse functions is determined based on the theory of discourse analysis. Prosodic features in the speech and a correlation between the prosodic features and the discourse functions is determined. The sets of candidate discourse functions are ranked based on the prosodic features in the speech information and a correlation to the prosodic features expected for the determined discourse functions. Ambiguity is resolved between sets of candidate discourse functions based ...

    14. System and method for teaching writing using microanalysis of text

      A technique for teaching expository writing using a system that provides an objective reader centric microanalysis of the information a writer has conveyed to a virtual reader. The technique uses a theory of discourse analysis such as the Linguistic Discourse Model. Using the technique, a text is segmented into discrete units of meaning of the selected theoretic model. Student analysis and understanding are facilitated by the assignment of types to the discrete units of meaning and by linking the discrete units of meaning into a discourse tree under the constraints imposed by the selected theory. A virtual, or objective, reader ...
