COMBINE_LANG_MODEL(1) ===================== :doctype: manpage NAME ---- combine_lang_model - generate starter traineddata SYNOPSIS -------- *combine_lang_model* --input_unicharset 'filename' --script_dir 'dirname' --output_dir 'rootdir' --lang 'lang' [--lang_is_rtl] [pass_through_recoder] [--words file --puncs file --numbers file] DESCRIPTION ----------- combine_lang_model(1) generates a starter traineddata file that can be used to train an LSTM-based neural network model. It takes as input a unicharset and an optional set of wordlists. It eliminates the need to run set_unicharset_properties(1), wordlist2dawg(1), some non-existent binary to generate the recoder (unicode compressor), and finally combine_tessdata(1). OPTIONS ------- '--lang lang':: The language to use. Tesseract uses 3-character ISO 639-2 language codes. (See LANGUAGES) '--script_dir PATH':: Directory name for input script unicharsets. It should point to the location of langdata (github repo) directory. (type:string default:) '--input_unicharset FILE':: Unicharset to complete and use in encoding. It can be a hand-created file with incomplete fields. Its basic and script properties will be set before it is used. (type:string default:) '--lang_is_rtl BOOL':: True if language being processed is written right-to-left (eg Arabic/Hebrew). (type:bool default:false) '--pass_through_recoder BOOL':: If true, the recoder is a simple pass-through of the unicharset. Otherwise, potentially a compression of it by encoding Hangul in Jamos, decomposing multi-unicode symbols into sequences of unicodes, and encoding Han using the data in the radical_table_data, which must be the content of the file: langdata/radical-stroke.txt. (type:bool default:false) '--version_str STRING':: An arbitrary version label to add to traineddata file (type:string default:) '--words FILE':: (Optional) File listing words to use for the system dictionary (type:string default:) '--numbers FILE':: (Optional) File listing number patterns (type:string default:) '--puncs FILE':: (Optional) File listing punctuation patterns. The words/puncs/numbers lists may be all empty. If any are non-empty then puncs must be non-empty. (type:string default:) '--output_dir PATH':: Root directory for output files. Output files will be written to //.* (type:string default:) HISTORY ------- combine_lang_model(1) was first made available for tesseract4.00.00alpha.
