From structure to interpretation: A double-layered annotation for event factuality Roser Saur´ı and James Pustejovsky Lab for Linguistics and Computation Computer Science Department Brandeis University roser,jamesp @cs.brandeis.edu { } Abstract Current work from different areas in the field points out the need for systems to be sensitive to the factuality nature of events mentioned in text; that is, to recognize whether events are presented as corresponding to real situations in the world, situations that have not happened, or situations of uncertain status. Event factuality is a necessary component for representing events in discourse, but for annotation purposes it poses a representational challenge because it is expressed through the interaction of a varied set of structural markers. Part of these factuality markers is already encoded in some of the existing corpora but always in a partial way; that is, missing an underlying model that is capable of representing the factuality value resulting from their interaction. In this paper, we present FactBank, a corpus of events annotated with factuality information which has been built on top of TimeBank. Together, TimeBank and FactBank offer a double-layered annotation of event factuality: where TimeBank encodes most of the basic structural elements expressing factuality information, FactBank adds a representation of the resulting factuality interpretation. 1.

  • Talk Bank: a Multimodal Database of Communicative Interaction
    Talk Bank: A Multimodal Database of Communicative Interaction 1. Overview The ongoing growth in computer power and connectivity has led to dramatic changes in the methodology of science and engineering. By stimulating fundamental theoretical discoveries in the analysis of semistructured data, we can to extend these methodological advances to the social and behavioral sciences. Specifically, we propose the construction of a major new tool for the social sciences, called TalkBank. The goal of TalkBank is the creation of a distributed, web- based data archiving system for transcribed video and audio data on communicative interactions. We will develop an XML-based annotation framework called Codon to serve as the formal specification for data in TalkBank. Tools will be created for the entry of new and existing data into the Codon format; transcriptions will be linked to speech and video; and there will be extensive support for collaborative commentary from competing perspectives. The TalkBank project will establish a framework that will facilitate the development of a distributed system of allied databases based on a common set of computational tools. Instead of attempting to impose a single uniform standard for coding and annotation, we will promote annotational pluralism within the framework of the abstraction layer provided by Codon. This representation will use labeled acyclic digraphs to support translation between the various annotation systems required for specific sub-disciplines. There will be no attempt to promote any single annotation scheme over others. Instead, by promoting comparison and translation between schemes, we will allow individual users to select the custom annotation scheme most appropriate for their purposes.

  • Adapting to Trends in Language Resource Development: a Progress
    Adapting to Trends in Language Resource Development: A Progress Report on LDC Activities Christopher Cieri, Mark Liberman University of Pennsylvania, Linguistic Data Consortium 3600 Market Street, Suite 810, Philadelphia PA. 19104, USA E-mail: {ccieri,myl} AT ldc.upenn.edu Abstract This paper describes changing needs among the communities that exploit language resources and recent LDC activities and publications that support those needs by providing greater volumes of data and associated resources in a growing inventory of languages with ever more sophisticated annotation. Specifically, it covers the evolving role of data centers with specific emphasis on the LDC, the publications released by the LDC in the two years since our last report and the sponsored research programs that provide LRs initially to participants in those programs but eventually to the larger HLT research communities and beyond. creators of tools, specifications and best practices as well 1.

  • The Main Features of the E-Glava Online Valency Dictionary
    The Main Features of the e-Glava Online Valency Dictionary Matea Birtić, Ivana Brač, Siniša Runjaić Institute of Croatian Language and Linguistics, Ulica Republike Austrije 16, HR-10000 Zagreb, Croatia E.mail: [email protected], [email protected], [email protected] Abstract E-Glava is an online valency dictionary of Croatian verbs. The theoretical approach to valency follows the German tradition, particularly that of the VALBU dictionary, with some minor changes and adjustments. The main principle of our valency approach is to link valency patterns to specific verb meanings. The verb list is compiled semi-automatically on the basis of the Croatian Frequency Dictionary and Croatian language textbooks. Currently, e-Glava contains descriptions of 57 psychological verbs with 187 meanings and 375 valency patterns. The lexicographic articles are written in Tschwanelex. A Document Type Definition editing module has been used, and the description of verbs follows a three-level linguistic schema prepared for lexicographers. Verbs are distributed throughout 34 semantic classes, and examples are extracted manually from Croatian corpora. Fully processed data for each semantic class will be publicly available in the form of a browsable HTML dictionary. The paper also presents a comparison between e-Glava and other cognate resources, as well as a summary of its main advantages, disadvantages, and potential applied uses. Keywords: Croatian language; valency dictionary; e-dictionary; syntax 1. Introduction Sentence structure and the syntactic behaviour of verbs were perhaps the most intriguing and interesting topics for early grammatical descriptions and, later, linguistic descriptions of language. Valency properties are relevant to both theoretical and applied linguistic considerations.

F. Jones Jussi Karlgren CLARIN ERIC Dublin City University Spotify [email protected] [email protected] [email protected] Ben Carterette Rosie Jones Spotify Spotify [email protected] [email protected] Abstract Podcasts are a large and growing repository of spoken audio. As an audio format, podcasts are more varied in style and production type than broadcast news, contain more genres than typi- cally studied in video data, and are more varied in style and format than previous corpora of conversations. When transcribed with automatic speech recognition they represent a noisy but fascinating collection of documents which can be studied through the lens of natural language processing, information retrieval, and linguistics. Paired with the audio files, they are also a re- source for speech processing and the study of paralinguistic, sociolinguistic, and acoustic aspects of the domain. We introduce the Spotify Podcast Dataset, a new corpus of 100,000 podcasts. We demonstrate the complexity of the domain with a case study of two tasks: (1) passage search and (2) summarization. This is orders of magnitude larger than previous speech corpora used for search and summarization. Our results show that the size and variability of this corpus opens up new avenues for research.

Abstract This thesis has two aims: developing resources for Arabic dialects and improving the speech recognition of Arabic dialects. Two important components are considered: Pro- nunciation Dictionary (PD) and Language Model (LM). Six parts are involved, which relate to finding and evaluating dialects resources and improving the performance of sys- tems for the speech recognition of dialects. Three resources are built and evaluated: one tool and two corpora. The methodology that was used for building the multi-dialect morphology analyser involves the proposal and evaluation of linguistic and statistic bases. We obtained an overall accuracy of 94%. The dialect text corpora have four sub-dialects, with more than 50 million tokens.
