An Optimal and Portable Parsing Method for Romanian, French, and German Large Dictionaries

摘要

This paper presents a cross cross-linguistic analysis of the largest dictionaries cu cur- rrently existing for Romanian, French, and rently German, and a new, robust and portable method for Dictionary Entry Parsing (DEP), based on Se Segmentation mentation- Cohesion Cohesion-Dependency (SCD) configur configura- ations. The SCD configurations are a tions. ap- pplied successively on each dictionary e plied en- ntry to identify its lexicographic se try segments ments (the first SCD configuration), to extract its sense tree (the second conf configuration), guration), and to parse its atomic sense definitions (the third one). Using pr previous results on vious DLR (The Romanian Thesaurus ?new format), the present paper adapts and a ap- pplies the SCD plies SCD-based technology to other four large and complex thesauri: DAR (The Romanian Thesaurus ?old format), TLF (Le Tr閟or de la Langue Fran?Fran鏰ise), aise), DWB (Deutsches W鰎terbuch ?GRIMM), and GWB (G鰐he G鰐he- W鰎terbuch). This experiment is ill illu- ustrated on significantly large parsed e strated en- ntries of these thesauri, and proved the fo tries fol- llowing features: lowing (1) the SCD SCD-based m me- ethod is a co thod completely pletely formal grammar grammar- free approach for dictionary parsing, with pproach efficient (weeks weeks-time adaptable) mode model- ling through sense hierarchies and parsing ing portability for a new dictionary. (2) SCD SCD- configurations separate and run seque sequen- ntially and independently the processes of tially lexicographic seg segment re ment recognition, sense ognition, tree extraction, and atomic definition parsing. (3) The whole DEP process with SCD SCD-configurations is optimal optimal. (4). SCD SCD- configurations, through sense marker classes and their dependency hype hyper- rgraphs, offer an unique instrument of le graphs, lex- xicon construction comparison, sense co icon con- ncept design and DEP standardiz cept standardization. tion.
