Sažetak
In this paper we present the semantic analysis module in F-logic as a part of a Croatian spoken dialog system developed for a limited domain of weather forecasts. Semantic analysis is implemented as an information extraction technique using the F-logic formalism. F-logic (Frame Logic) is a logic formalism with a second order syntax and an object-oriented approach. Semantic knowledge is captured through semantic categories, a semantic dictionary and output frames represented in F-logic. The developed semantic analysis is conducted in three phases. In the first phase the main semantic context for the input text is determined. In the second phase semantic units are analysed and knowledge slots in the database are filled. Since some slots of input data are missing in the third phase, incomplete data are updated with missing values. The semantic analysis is evaluated with 3 months period weather data in terms of frame rates and slot error rates. The rules for semantic analysis are defined in the F-logic language and implemented using the FLORA-2 system.
