SignLinC: Linking lexical databases and annotated corpora of signed

Summary

The core of SignLinC consists of enhancements for LEXUS 3.0 and ELAN 4.0, both released at the start of 2011.

Background

Additions to ELAN include the following:

Addition of a "Lexicon" tab at the top right of the interface. Annotations on a gloss tier can be looked up in a LEXUS lexicon. The user can select which fields from LEXUS to display in the Lexicon tab. (li)The possibility of creating a link to an 'external controlled vocabulary' that is published on a web server, and that can be modified independently of specific EAF files. Displaying and browsing a very long list of items in the pop-up menu that appears when creating an annotation on a tier that is linked to an External Controlled Vocabulary (ECV) is optimised by a number of preference options. At this moment it is not yet possible to generate an ECV from within LEXUS, but this will likely be included in future releases of LEXUS.

ANNEX, the online sibling of ELAN, has been modified independently of the project to allow the creation of URL-style links to segments of annotation files on a server. These links can be included on web pages, power-point presentations, or PDF files. In this way, quick access to published annotations is possible from within lexical resources.

SignLinC links two independently evolved data sets for a signed language: the Corpus NGT and the lexical database of the Dutch Sign Centre. The first is a corpus of video texts that was already fully compliant with CLARIN standards, while the latter is an independently evolved Microsoft SQL database. Both are prototypical for the situation of signed language resources in the world: corpora of running signing have only recently been under development and typically use ELAN as the annotation tool, while lexical databases have typically evolved as standalone applications to produce dictionaries in books or on CD/DVD-ROMs. In order to establish a link in both directions, a conversion of relevant parts of the lexical database to the CLARIN LMF standard for lexica was created for a small test set of lemmata.
The SignLinC project was a collaboration between Radboud University, the Dutch Sign Centre (NGc), and the MPI for Psycholinguistics; it was funded by CLARIN-NL and was completed in 2011.

VALID - vulnerability in language acquisition: language impairments in Dutch

Summary

An open access multimedia archive of language pathology data collected in the Netherlands, primarily on Dutch, audio files and transcripts. Currently, this corpus contains 5 different data sets. In the VALID data archive old, current and future data can be brought together.

Background

VALID, an open access multimedia language data archive, facilitates and promotes innovative research in the area of language impairment. There are a number of compelling reasons for exchanging and sharing this kind of data. Obviously, in a small country like the Netherlands a considerably smaller amount of language data is being collected than in much larger regions, especially so with respect to language disorders, a highly specific research domain. The combination of a wide range of language impairments in one data archive not only enhances the study of similar impairments but also advances comparisons between different disorders. Moreover, the inclusion of different age groups allows for quasi-longitudinal research designs. Finally, analysis of task properties and effects that are specific to pathological language groups can make a significant contribution to evidence-based research.

The following data sets define the launching platform for the VALID data archive, together with the BISLI data set that is currently being curated (FESLI):

The SLI RU-Kentalis database: the expression of spatial relations by children with SLI and normally developing children in their spoken language production
The UU SLI-Dyslexia project database: early language development in children at familial risk of dyslexia
The bilingual deaf children RU-Kentalis database: the bilingual language and communication development of young deaf children in Sign Language of the Netherlands (SLN) and Dutch (D)
The ADHD and SLI corpus UvA database: the language and executive functioning profiles of children with ADHD and children with SLI and TD children
The deaf adults RU database: the acquisition of morphosyntactic aspects of Dutch by deaf Dutch adults (late L1/early L2) and hearing Turkish and Moroccan-Arabic L2-learners of Dutch (late L2).

For all data sets concerned, written informed consent from the participants or their caretakers has been obtained. Informants or their caretakers have agreed to share their speech/language data and metadata, on the condition of anonymity, which will be ensured by the data providers and infrastructure specialists Contacts
