The document discusses research on the semantic motivations for construction patterns used with the Polish verbs "myśleć" (to think) and "wierzyć" (to believe). It presents assumptions from Cognitive Grammar, describes the Polish PWN corpus used, and the methodology which involved tagging objects by case, type, and semantics. Quantitative analysis found differences in object characteristics between the verbs. Qualitative analysis explored the aspectuality and object semantics continua for each verb. The research aims to further understand subject and impersonal constructions, aspectuality, and genre specificity.
