Enquadramento
Today’s way to interact between a human and a computer system is changing. Computer systems are becoming more intelligent in the way they communicate with humans, with the latest developments in Natural Language Processing helping a lot the improvement of speech recognition and conversational interaction, like bots and home appliances (Echo and Google Home). The days of having computer personal assistants has come, with Siri, Cortana and others. However, specific applications require domain-specific virtual assistants with improved understanding of the domain language and custom actions integrated with diverse APIs and libraries.
Critical Software developed Lexia, a platform for the development of custom virtual assistants, that is now moving into production integrated with Critical’s own internal platforms. During this process we have established the directions for future development and intend to kick-off the implementation of Lexia 2.0. In particular, this internship encompasses a requirements’ analysis and consequent development to build several new capabilities into Lexia, namely migrate the NLU component to use new types of models like BERT and similar transformers-based models, new end-to-end DIET (Dual Intent and Entity Transformers) models, improving the configuration management especially concerning the inclusion of incremental language models, and improve the multi-language capabilities already built into Lexia.
Objetivo
The main goal of this internship is to design and implement the next version of Lexia, specifically:
- Migrate the NLU to Rasa2 and include the relevant new features like new NLU models.
- Improve configuration management by including incremental language and domain models.
- To improve the general functionality of the assistants it is necessary to fine-tune the language detection model to improve recognition for short sentences, but this would be an extra.
Plano de Trabalhos - Semestre 1
The internship has the following stages:
- Defining the Scope and Requirements [result: requirement list, M1 and M2]
- Study of the Lexia platform [result: platform description, M1 to M2]
- Study of the RASA platform [result: platform description, M1 to M4]
- Creating the Technical Specification [result: technical specification, M4 and M5]
- Writing the internship proposal [result: internship proposal, M5 and M6]
Plano de Trabalhos - Semestre 2
The second semester comprises the following stages:
- Setting up the Development Environment [result: Development Environment, M6]
- Development [result: first prototype, M7 to M9]
- Testing and Benchmarking [result: second prototype, M10]
- Writing the internship report [result: internship report, M10 and M11]
