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

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.
