The phrase 'logico-computational philosophy' was coined by Witold Marciszewski to deal with problems which could be characterised as a modern Renaissance observed in the domain of science since the emergence of cybernetics and computer science. This renaissance was made possible by the use of universal programming languages in different areas of science. The authoress claims that thanks to the Polish logico-mathematical heritage (stemming from the Warsaw-Lwow School of Logic and Philosophy at the beginning of the 20th century) there is a chance that Polish linguistics might be present in this new age of science on the condition that it adopt the computational paradigm as developed within the realm of artificial intelligence. Investigations on the Polish language at CELTA Sorbonne (Centre de Linguistique theorique et appliqué) are conducted in the framework of what we call the CASK (Computer Aided Acquisition of Semantic Knowledge) method supported by the SEMANA software which includes a dynamic database builder and a bundle of algorithms for knowledge discovery in databases (KDD) specifically selected for semantic analysis. This paper sketches out the results of research conducted on Polish adjective declension, subject-verb agreement (choice of past tense verb forms -li or -ly) and impersonal sentences, thereby giving evidence of the need to distinguish in Polish grammar, the category of ender form the three-valued category of animacy (non animate, human animate and non-human animate). The approach revealed that the grammatical category of Polish gender has only 3 values (masculine, feminine and neuter) instead of 5, 7, 8 or even 9 values (which, in fact, correspond do declension classes) of a hybrid gender-like category as proposed by today's grammarians of Polish. Thus, the CASK method makes it possible to describe the Polish grammar using common European linguistic technology.

The authoress' aim is the formalisation of semantic concepts using experimental Computer-aided Acquisition of Semantic Knowledge (CASK) method. This method is being used at CELTA with the SEMANA (SEMantic ANAlyser) software which was especially designed for this purpose. The case study she proposes is the experimental research on Aspect in Polish: she shows how although rich nevertheless intuitive notions resulting from years of traditional research can be formalised with computational methods of data analysis. She uses the notation close to that of Semantic Feature Structures as a representation language for describing the category of aspect in Polish taking into account not only the grammatical core of this category but also the whole semantic field (called 'aspectuality' by A.V. Bondarko) regardless of its pertaining to various levels of expression (morphological, syntactical or lexical). To model the Category of Aspect the authoress treats ontological types of situations as conditions for two relevant aspect parameters she calls Analysis of the situation (or Internal Aspect) and Control of the situation (or External Aspect). In order to cope both with the lexical diversity of aspectual morphemes (prefixes) and the grammatical (dichotomous and obligatory) character of aspect in Slavic languages, she has proposed to define the perfective aspect as a hypercategory. The database of Polish Aspect was analysed using KDD statistical tools (Sauvet (2008)): thus, she obtained the first preliminary experience-based semantic definitions of the perfective and imperfective values of the category of aspect in a Slavic language.
