What's file format of dictionary

mnjkl · 12-11-2011, 11:40 AM

I am looking into the dictionary of kobo and thinking of ways to build a dictionary.

It seems that each dictionary takes a folder. Under each folder, there is a file 'words' and some '.html' files. '.html' is a compressed gzip file. File 'words' should be a word list, but I don't know how it is compressed.

Can anyone give some information?

Just a message to let you know I had the same conclusions ... and questions about the word file.

Hope someone will find some meaning.

I found something from http://code.google.com/p/marisa-trie/

Matching Algorithm with Recursively Implemented StorAge (MARISA) is a static and space-efficient trie data structure. And libmarisa is a C++ library to provide an implementation of MARISA. Also, the package of libmarisa contains a set of command line tools for building and operating a MARISA-based dictionary.
A MARISA-based dictionary supports not only lookup but also reverse lookup, common prefix search and predictive search.
•Lookup is to check whether or not a given string exists in a dictionary.
•Reverse lookup is to restore a key from its ID.
•Common prefix search is to find keys from prefixes of a given string.
•Predictive search is to find keys starting with a given string.
