In this paper we investigate the coverage of the two knowledge sources WordNet and Wikipedia for the task of bridging resolution. We report on an annotation experiment which yielded pairs of bridging anaphors and their antecedents in spoken multi-party dialog. Manual inspection of the two knowledge sources showed that, with some interesting exceptions, Wikipedia is superior to WordNet when it comes to the coverage of information necessary to resolve the bridging anaphors in our data set. We further describe a simple procedure for the automatic extraction of the required knowledge from Wikipedia by means of an API, and discuss some of the implications of the procedure’s performance.
Lexicon schemas and their use are discussed in this paper from the perspective of lexicographers and field linguists. A variety of lexicon schemas have been developed, with goals ranging from computational lexicography (DATR) through archiving (LIFT, TEI) to standardization (LMF, FSR). A number of requirements for lexicon schemas are given. The lexicon schemas are introduced and compared to each other in terms of conversion and usability for this particular user group, using a common lexicon entry and providing examples for each schema under consideration. The formats are assessed and the final recommendation is given for the potential users, namely to request standard compliance from the developers of the tools used. This paper should foster a discussion between authors of standards, lexicographers and field linguists.
The metadata management system for speech corpora “memasysco” has been developed at the Institut für Deutsche Sprache (IDS) and is applied for the first time to document the speech corpus “German Today”. memasysco is based on a data model for the documentation of speech corpora and contains two generic XML schemas that drive data capture, XML native database storage, dynamic publishing, and information retrieval. The development of memasysco’s information architecture was mainly based on the ISLE MetaData Initiative (IMDI) guidelines for publishing metadata of linguistic resources. However, since we also have to support the corpus management process in research projects at the IDS, we need a finer atomic granularity for some documentation components as well as more restrictive categories to ensure data integrity. The XML metadata of different speech corpus projects are centrally validated and natively stored in an Oracle XML database. The extension of the system to the management of annotations of audio and video signals (e.g. orthographic and phonetic transcriptions) is planned for the near future.
The Meta-data-Database of a Next Generation Sustainability Web-Platform for Language Resources
(2008)
Our goal is to provide a web-based platform for the long-term preservation and distribution of a heterogeneous collection of linguistic resources. We discuss the corpus preprocessing and normalisation phase that results in sets of multi-rooted trees. At the same time we transform the original metadata records, just like the corpora annotated using different annotation approaches and exhibiting different levels of granularity, into the all-encompassing and highly flexible format eTEI for which we present editing and parsing tools. We also discuss the architecture of the sustainability platform. Its primary components are an XML database that contains corpus and metadata files and an SQL database that contains user accounts and access control lists. A staging area, whose structure, contents, and consistency can be checked using tools, is used to make sure that new resources about to be imported into the platform have the correct structure.
The research project “German Today” aims to determine the amount of regional variation in (near-)standard German spoken by young and older educated adults and to identify and locate regional features. To this end, we compile an areally extensive corpus of read and spontaneous German speech. Secondary school students and 50-to-60-year-old locals are recorded in 160 cities throughout the German speaking area of Europe. All participants read a number of short texts and a word list, name pictures, translate words and sentences from English, answer questions in a sociobiographic interview, and take part in a map task experiment. The resulting corpus comprises over 1000 hours of speech, which is transcribed orthographically. Automatically derived broad phonetic transcriptions, selective manual narrow phonetic transcriptions, and variationalist annotations are added. Focussing on phonetic variation we aim to show to what extent national or regional standards exist in spoken German. Furthermore, the linguistic variation due to different contextual styles (read vs. spontaneous speech) shall be analysed. Finally, the corpus enables us to investigate whether linguistic change has occurred in spoken (near-)standard German.
The authors describe two data sets submitted to the database of MWE evaluation resources: (1) cranberry expressions in English and (2) cranberry expressions in German. The first package contains a collection of 444 cranberry words in German (CWde.txt) and a collection of the corresponding cranberry expressions (CCde.txt). The second package consists of a collection of 77 cranberry words in English (CWen.txt) and a collection of the corresponding cranberry expressions (CCen.txt). The data included in these packages was extracted from the Collection of Distributionally Idiosyncratic Items (CoDII), an electronic linguistic resource of lexical items with idiosyncratic occurrence patterns. Each package contains a readme file, and can be downloaded from multiword.wiki.sourceforge.net/Resources.
