Thoth's Suggested Tags is a WordPress plugin that recommends tags by scanning a post and displaying recurring words and phrases as a tag cloud.
1.3 (July 26, 2010)
Reinforced stop-words list to better filter irrelevant tags
Fixed a bug where the database checking for tags was done on an empty database (this only occurred in WordPress MU)
1.2 (July 21, 2010)
Implemented capitalization check so that any capitalized word that also appears in the post in lowercase is automatically converted to lowercase (since it cannot be a proper noun).
Added an asterisk indicator at the end of tags that were matched to the database.
1.1 (July 13, 2010)
Added support for proper nouns and proper phrases using capital letters (e.g. "Grapes of Wrath" is a proper phrase and gets a higher recommendation).
Added a "video" and "audio" tag recommendation if any embedded video or audio files are detected in the post.
Implemented a check for duplicate tags. Previously, (for example) the tag "Windows Vista" with a strength of 6 would also generate tags "Windows" and "Vista" both with strengths of 6. This redundancy is now removed; tags will only be counted when they are not contained in another already recommended tag.
Reworked the entire post-processing code structure for better efficiency and readability.
Set default meta-box position to the sidebar
