Why top detection?

?

Generally, one postfocus on one topic which may mainly from the first poster. We should reflectthe relationship between posts which under the same thread. But now we justsave every post into DB, but have no relationship between these posts.

?

So, the default levelfor detecting topics is Thread rather than one single post. As we can see, mostposts just have several lines of context or less and that's not enough fordetecting topics from. My idea is, for detecting topics, first, we should combine posts which under thesame thread.

Kea is based onmachine learning algorithms, so it need to be trained before you use it. Fortraining Kea, you need to provide some sample files (.txt and .key pairs).
