Logical analysis should just offer a “bridge between language ex-pressions.” In this paper, we show the preliminary results of automated bilingual logical analysis, namely the analysis of English and Czech sentences. The underlying logical formalism, the Transparent Intensional Logic (TIL), is a representative of a higher-order temporal logic designed to express full meaning relations of natural language expressions. We present the details of the current development and preparations of the supportive lexicons for the AST (automated semantic analysis) tool when working with a new language, i.e. English. The AST provides an implementation of the Normal Translation Algorithm for TIL aiming to offer a normative logical analysis of the input sentences. We show the simila...

The editor was recently re-developed as a multi-platform web-based application for general semantic networks editing. One of the main advantages, when compared to the previous implementation, lies in the fact that no client-side installation is needed now. Following the successful first phase in building the Open Dutch Wordnet, DEBVisDic was extended with features that allow users to easily create, edit, and share a new (usually national) wordnet without the need of any complicated configuration or advanced technical skills. The DEBVisDic editor provides advanced features for wordnet browsing, editing, and visualization. Apart from the user-friendly web-based application, DEBVisDic also provides an API interface to integrate the semantic network data into external applications.

Automaticke kontroly konzistence mohou odhalit systemove chyby, např. chybějici odkazy, ale nalezt chybějici význam slova je obtižne. Běžna řeseni spolehaji na postupne konzultace mnoha informacnich zdrojů při postupnem recenznim řizeni. V clanku je popsan nový přistup pro ověřeni a rozsiřovani dat wordnetu pomoci zapojeni uživatelů. Tento přistup zajisťuje brzke vydani plne datove sady pro použiti cilovou skupinou s pozdějsimi neustalými upravami podle navrhů veřejných uživatelů a kontrolou těchto navrhů experty. Tým expertů ma k dispozici navrhy oprav v přehledne agregovane podobě, a take podporou revizi a editace.

The system allows to radically enhance the workow of current terminology expert groups, where most of the editing decisions still come from introspection. The presented system supplements the lexicographic process with natural language processing techniques, which are seamlessly integrated to the thesaurus editing environment. The system’s methodology and the resulting thesaurus are closely connected to new domain corpora in the six languages involved. They are used for term usage examples as well as for the automatic extraction of new candidate terms. The terminological thesaurus is now accessible via a web-based application, which (a) presents rich detailed information on each term, (b) visualizes term relations, and (c) displays real-life usage exam...

However, many new concepts and even new research areas have emerged since that publication. That is why a preparation of a complete new edition of the encyclopaedia started in 2011, rather than just re-printing the previous version with supplements. The new edition covers current research status in all concepts connected with the linguistic studies of (prevalently, but not solely) the Czech language. The project proceeded for five years and it has finished at the end of 2015, the printed edition is currently in preparation. An important innovation of the new encyclopaedia lies in the decision that the new edition will be published both as a printed book and as an electronic on-line encyclopaedia, utilizing the many advantages of electronic dictionaries.In t...

Intensional logic systems, such as the Transparent Intensional Logic (TIL), can rigorously describe even the higher-order relations between the speaker and the content or meaning of the discourse. In this paper, we concentrate on the mechanism of logical analysis of direct and indirect discourse by means of TIL. We explicate the procedure within the Normal Translation Algorithm (NTA) for Transparent Intensional Logic (TIL), which covers ...
