Strategia wyboru komunikatu modalnego w dialogowym systemie wspomagania decyzji

tom nr 1

21-35

Przedstawiono strategię udzielania odpowiedzi modalnych przez interaktywny system wspomagania decyzji. Rozpatrzono sytuację niekompletności wiedzy systemu na temat stanu świata (obiektu sterowania), wymuszającą koniecznością generowania odpowiedzi zbudowanych z modalnych operatorów przekonań i możliwości. Przyjęto, że system dysponuje językiem złożonym z modalnych rozszerzeń wybranych formuł i rachunku zdań.

A strategy for the of modal response by an interactive decision support system is presented. The situation of incomplete knowledge of the world (control object) is considered. The response are modal belief and possibility extensions of logic formulas. The strategy has been originally used for communicative cognitive agents and is tailored to model some aspects of information processing in a business organisation. This organisationis treated as a conceptual agent in which particular observations of the world's states are stored in distributed databases. All observations are then re-processed in order to store them in a certain data warehouse from which the responses are extracted. The consensus-based algorithm for the choice of the most relevant response is given.

In this paper we deal with an original technically oriented model for cognitive semantics. As the expected area of application we focus on the process of extraction of modal linguistic summaries from data managed by autonomous components of ambient systems and intelligent environments. As such, the cognitive semantics is defined for a particular case of modal natural language statements with epistemic modalities. The statements of interest are built with natural language operators, representing epistemic modalities (related to the main cognitive states of knowledge certainty: full certainty, strong belief and epistemic possibility), and natural language connectives of equivalence. Furthermore, an approach to their effective processing by autonomous computational systems is designed. An internal architecture of the autonomous computational component is designed with respect to modular model for natural language processing with separate modules for epistemic and semantic memory storage and processing. An original theoretical concept underlying the model of semantic memory is a holon defined as a collection of complementary linguistic protoforms. Finally, we provide several illustrative computational examples of linguistic summaries’ extraction, based on artificial and real data.
