  abstract  = {In this article, we present Quevedo, a software tool we have developed for the task of automatic processing of graphical languages. These are languages which use images to convey meaning, relying not only on the shape of symbols but also on their spatial arrangement in the page, and relative to each other. When presented in image form, these languages require specialized computational processing which is not the same as usually done either for natural language processing or for artificial vision. Quevedo enables this specialized processing, focusing on a data-based approach. As a command line application and library, it provides features for the collection and management of image datasets, and their machine learning recognition using neural networks and recognizer pipelines. This processing requires careful annotation of the source data, for which Quevedo offers an extensive and visual web-based annotation interface. In this article, we also briefly present a case study centered on the task of SignWriting recognition, the original motivation for writing the software. Quevedo is written in Python, and distributed freely under the Open Software License version 3.0.}

  abstract  = {Representation of linguistic data is an issue of utmost importance when developing language resources, but the lack of a standard written form in sign languages presents a challenge. Different notation systems exist, but only SignWriting seems to have some use in the native signer community. It is, however, a difficult system to use computationally, not based on a linear sequence of characters. We present the project "VisSE", which aims to develop tools for the effective use of SignWriting in the computer. The first of these is an application which uses computer vision to interpret SignWriting, understanding the meaning of new or existing transcriptions, or even hand-written images. Two additional tools will be able to consume the result of this recognizer: first, a textual description of the features of the transcription will make it understandable for non-signers. Second, a three-dimensional avatar will be able to reproduce the configurations and movements contained within the transcription, making it understandable for signers even if not familiar with SignWriting. Additionally, the project will result in a corpus of annotated SignWriting  data which will also be of use to the computational linguistics community.}

  abstract  = {The SignWriting improved fast transcriber (SWift), presented in this paper, is an advanced editor for computer-aided writing and transcribing of any Sign Language (SL) using the SignWriting (SW). The application is an editor which allows composing and saving desired signs using the SW elementary components, called ``glyphs''. These make up a sort of alphabet, which does not depend on the national Sign Language and which codes the basic components of any sign. The user is guided through a fully automated procedure making the composition process fast and intuitive. SWift pursues the goal of helping to break down the ``electronic'' barriers that keep deaf people away from the web, and at the same time to support linguistic research about Sign Languages features. For this reason it has been designed with a special attention to deaf user needs, and to general usability issues. The editor has been developed in a modular way, so it can be integrated everywhere the use of the SW as an alternative to written ``verbal'' language may be advisable.}

  abstract  = {This paper aims to address and clarify one issue we believe is crucial in constructing Sign Languages (SL) corpora: identifying appropriate tools for representing in written form SL productions of any sort, i.e. lexical items, utterances, discourse at large. Towards this end, building on research done within our group on multimedia corpora of both SL and spoken or verbal languages (vl), we first outline some of the major requirements and guidelines followed in current work with vl corpora (e.g. regarding transcription, representation [mark-up], coding [or annotation] Chiari, 2007; Edwards {\&} Lampert; 1993; Leech {\&} al, 1995; Ochs, 1979; Powers, 2005, among others). We highlight that a basic requirement of vl corpora is an easily readable transcription that, aside from specialist linguistic annotations, allows anyone who knows the object language to reconstruct its forms, and its form-meaning correspondences. Second, we show how this basic requirement is not met in most current work on SL, where the `transcription' of SL productions consists primarily of word-labels taken from vl, inappropriately called `glosses'. As argued by some authors (e.g. Pizzuto {\&} Pietrandrea, 2001; Russo, 2005; Pizzuto et al., 2006), the use of such word-labels as a primary representation tool grossly misrepresents SL, even when supported by specialist linguistic annotations (e.g. Stokoe-based notations, the Berkeley Transcription System [Slobin et al., 2001]). Drawing on a crosslinguistic overview of relevant work on SL lexicon and discourse (e.g. Brennan, 2001; Cuxac, 2000; Cuxac {\&} Sallandre, 2007; Russo, 2004; Antinoro Pizzuto et al., 2007), we illustrate how the `transcriptions' most widely used for SL do not allow to anyone who knows the specific SL to reconstruct its forms and form-meaning correspondences, and are especially inadequate for representing complex sign units that are very frequent in SL discourse, and exhibit highly iconic, muldimensional/multilinear features that have no parallel in vl. Third, we present and discuss ongoing research on Italian Sign Language (LIS) in which experienced deaf signers explore the use of SignWriting (Sutton, 1995) as a tool for both composing texts conceived in written form -- thereby creating a corpus of written LIS -- and for transcribing corpora of face-to-face LIS discourse (Di Renzo et al., 2006; Di Renzo, in press; Lamano et al., in press). The results show that, in both cases, deaf signers can easily represent the form-meaning patterns of their language with an accuracy never experienced with other representation or notation systems. The analysis of the texts produced has also provided new indications on the structure of LIS, highlighting the need of revising the criteria for constructing lexical corpora on the grounds of regularities (and variance) found in discourse corpora. While all of this suggests that SignWriting can be a valuable tool for addressing the representation issue in constructing SL corpora, the present computerized form of SignWriting poses technical problems that severely constrain its use. We conclude specifying the problems that need to be faced for conducting more extensive experimentations.}

Unicode is the most popular encoding of characters aimed at unifying the various language-oriented encodings into a single format supporting every human language. This paper focuses on the first functional layer, which gives a correspondence between a SignWriting sign and a series of bytes. This is one of the prerequisites to represent a sign language electronically. The different possibilities to encode a given SignWriting sign are evaluated and compared on different criteria : the Unicode space requirements, the number of bytes the storage will require, the mathematical complexity and the side advantages offered. Keeping as much as possible of the information on how signs are written and entered, and offering capabilities to easily compare the symbols that compose these signs is also considered, so that the encoding can serve to study and compare how SignWriting is written. A reference encoding is then proposed, to serve as a basis for the next layers. Other bi-dimensional writing formalisms, currently not supported by Unicode, are considered to extend the presented work.}

Each sign box (basic sign) is then converted to a sequence of Body Animation Parameters (BAPs) of the MPEG-4 standard, corresponding to the represented gesture. These sequences, which can also be coded and/or reproduced by MPEG-4 BAP players, are then used to animate H-anim compliant VRML avatars, reproducing the exact gestures represented in sign language notation. Envisaged applications include producing signing avatars for interactive information systems (Web, E-mail, info-- kiosks) and TV newscasts for persons with hearing disabilities.}
