此贴介绍sunpinyin. 它的用户词典是~/.sunpinyin/userdict，下面的程序往里面加词：
// -I/usr/include/sunpinyin-2.0 add-word.cpp -lsunpinyin #include <ime-core/userdict.h> #include <pinyin/pinyin_data.h>TSyllable (*py2i)(const char*) = CPinyinData::encodeSyllable;int main(int argc, char** argv) {if (argc != 2) return 0;CUserDict ud;ud.load(argv[1]); // 文件可以不存在 CSyllables slbs; // typedef vector<TSyllable> CSyllablesslbs.resize(2);slbs[0] = py2i("yi");slbs[1] = py2i("er");// If locale is an empty string, ""... is set according to the environment variablessetlocale(LC_CTYPE, "");unsigned wcs[3] = {};int n = mbstowcs((wchar_t*)wcs, "①②", 2);ud.addWord(slbs, wcs);return 0; }
多次加同一个词不会出来n条。
userdict是个sqlite数据库，里面有且仅有一张表dict. 下面是常用sqlite 命令：
导入导出sqlite3 file.db .dump >dump.sql sqlite3 file.db <dump.sql.tables - 查看所有表名 .schema 表名 - 查看特定表结构select * from dict ;
不用编译它的源码，用现成的程序也能训练出online用的数据。程序在包sunpinyin-utils里：
- genpyt - generate the PINYIN lexicon
- getwordfreq - print word freq information from language model
- idngram_merge - merge idngram file into one
- ids2ngram - generate n-gram data file from ids file
- mmseg - maximum matching segment Chinese text
- slmbuild - generate language model from idngram file
- slminfo - get information of a back-off language model
- slmpack - convert the ARPA format of SunPinyin back-off language model to its binary representation
- slmprune - prune the back-off language model to a reasonable size
- slmseg - maximum matching segment Chinese text. slmthread add back-off-state for each slm node in the primitive_slm. Also it compresses 32-bit float into 16 bit representation. These processing speeds up the looking up. The primitive_slm is always generated by slmprune. And the threaded_slm can be used to feed slmseg as a reference to segment Chinese text.
- slmthread - threads the language model
- tslmendian - change the byte-order of sunpinyin's threaded back-off language model
- tslminfo - get information of a threaded back-off language model
不是所有的程序都要用到。
