Interface for the system for fast search of Maya glyphs based on their visual structural description: Compressed as EXE file or Compressed as ZIP file.

Beta-version. The system uses the dictionary of J. Montgomery.

EXE: Download the Glyphs.exe file, execute it, the files will be copied to the folder you choose. Then execute the file SETUP.EXE.

ZIP: Download the Glyphs.zip file, unzip files to the folder you choose . Then execute the file SETUP.EXE.

 

NEW Version 04/09/2009. If you downloaded the previous version, please, reinstall it.

 

 

Paper for citing for glyph search system:

System for automatic morphological analysis of Spanish NEW: A complete wordlist (beta-version) generated with this system is available.

 

System for automatic morphological analysis of Russian

 

These are EXE files for Windows; DLLs are available on request.

These are the programs that perform lemmatization and provide grammar information of each word form of Spanish or Russian correspondingly.

See detailed description on the corresponding pages – follow the links.

Download concordances for Russian (EXE for Windows). This is a program that allows for construction of concordances for Russian language. Its interesting feature is that it can construct concordances for a set of grammar categories, e.g., all nouns in dative, singular.
