Intelligent Voice Assistant Based on Open Semantic Technology

The paper considers the approach to building a personal assistant based on the open semantic technology (OSTIS). The key idea of our approach is the transition from processing a message in speech form to a formalized representation of the meaning in a knowledge base with the least number of intermediate stages. Knowledge base is built on the basis of a semantic network implemented using OSTIS technology. In this case, many tasks of the syntactic, semantic and pragmatic levels of natural language processing, for example, such as recognition of named entities (NEM) and definition of a part of speech (POS), dialogue management (intentions identifications and directives forming), can be performed directly in the knowledge base of the intelligent assistant. This will make it possible to effectively solve such problems as managing the global and local context of the dialogue, resolving linguistic phenomena such as anaphores, homonymy and eleptical phrases, correctly formulating answers to questions that are complex in structure and content, posed by the user during the dialogue.
