“…This is a problem when the communication counterpart expects to hear typical and intelligible utterances. We have developed a novel technique for expanding spontaneous telegraphic input to well-formed sentences, by adopting a feature-based surface realization for natural language generation [Karberis and Kouroupetroglou 2002]. …”

As an answer to the disabled community's odyssey to gain access to adaptable, modular, multilingual, cheap and sustainable Augmentative and Alternative Communication (AAC) products, we propose the use of the ITHACA framework. It is a software environment for building componentbased AAC applications, grounded on the Design for All principles and a hybrid-community and commercial-Open Source development model. ITHACA addresses the developers, the vendors, as well as the people who use AAC. We introduce a new viewpoint on the AAC product design-developdistribute lifecycle, and a novel way to search-select-modify-maintain the AAC aid. ITHACA provides programmers with a set of tools and reusable Open Source code for building AAC software components. It also facilitates AAC product vendors to put together sophisticated applications using the available on the Web, independently premanufactured, free or commercial software parts. Furthermore, it provides people who use AAC with a variety of compatible AAC software products which incorporate multimodal, user-tailored interfaces that can fulfill their changing needs. The ITHACA architecture and the proposed fusion of past and current approaches, trends and technologies are explained. ITHACA has been successfully applied by implementing a family of AAC products, based on interchangeable components. Several ready to use ITHACA-based components, including on-screen keyboards, Text-to-Speech, symbol selection sets, e-chatting, emailing, and scanning-based input, as well as four complete communication aids addressing different user cases have been developed. This demonstration showed good acceptance of the ITHACA applications and substantial improvement of the end users' communication skills. Developers' experience on working in ITHACA's Open Source projects was also positively evaluated. More importantly, the potential contribution of the component-based framework and Open Source development model combination to the AAC community emerged.

“…Furthermore, many cognitive impaired users, or users with learning problems are not able to from correct sentences. We have developed a novel technique for expanding spontaneous telegraphic input to well-formed sentences, by adopting a featurebased surface realization for Natural Language generation [25]. This component repairs grammatically and syntactically ill sentences while maintaining the semantics.…”

In this paper, we introduce a new generation of computerbased communication aids, designed and developed using state of the art software engineering models and architectures. The communicators we present are based on a component-based framework called ULYSSES that aims to simplify the integration of multi-vendor components into low cost products and maximizes modularity and reusability. Following the ULYSSES approach, one can build up powerful and reliable applications, adaptable to various user needs and requirements. For developers of AAC components, ULYSSES provides an engineering-forreuse environment with guidelines and tools to build software modules, which can operate effectively and interact with each other transparently, without even being aware of each other's existence. Furthermore, ULYSSES grants a process of engineering-with-reuse for AAC system integrators for the selection and assembly of components on demand to build user-specific robust communicators out of pre-fabricated software parts. Thus, adding or removing characteristics and features as needed, is becoming an easy task for system AAC systems integrators. Three complete Interpersonal Communication Aids are presented as cases of ULYSSES application in this specific domain.

“…In a sense, the users of symbol-based communication express themselves in their own language of symbol sequences. The sequences are often very brief and most of the words are omitted from them [3]. In some cases, the order of symbols within a message is also arbitrary [14].…”

“…There have been some attempts in the literature to generate sentences from symbol sequences in real time. These approaches are mostly rule-based, and languagedependent [3,4,7,9].…”

Difficulties in the communication of people with various movement and cognitive disorders may be alleviated by means of pictorial symbols. Automatic transformation of symbol sequences to natural language is of high importance. Performing this task by defining all valid sentences manually would require a large amount of work. We show that a small initial seed corpus is sufficient, which can be expanded automatically by generating candidate sentences and filtering them using N-gram statistics from a much larger corpus. The method is evaluated on a seed corpus containing dialogues, collected from an English language learning website. The ratio of useful sentences in the expanded corpus is 3-4 times bigger than in the set of unfiltered candidate sentences. We also use a manually constructed corpus for further evaluation. To demonstrate the practical applicability of the method, we have implemented a sentence production prototype that performs the transcription of symbol sequences to natural language. The system produces new and meaningful sentences and thus it can considerably decrease the size of the corpus needed, while it can increase the variability of sentences.
