The framework used to tag pages on Mises.org is a tagging library I developed to tag any kind of content on Mises.org. The tag library references GUID‘s assigned to all objects in the Mises.org databases.
It tracks users by username or IP address as well as the date that each tag was added. It includes spam/bad word filtering and has some simple tag rewriting to automatically correct misspelled words and incomplete names. For a simple tag example, see business cycle.
Update: Mises Tagging is now an open source project! See the project page for details.
The database schema gives a good indication of the
The interface is organized into self-contained user
- TagCloud.ascx – a tag cloud for the given document
Example: http://mises.org/resources/3250 (Sroll down)
- EditTags.ascx – an editable list of tagged
documents and a user-specific tag cloud.
(You’ll have to register at Mises.com tag some documents first.)
- TaggingStats.ascx – global tagging statistics
- DocumentTags.ascx – an editable list of tags for a particular
- Tags.aspx: delete tags, delete all tags by a particular user
and search/replace tags
You might have noticed that 99% of all tags are entered by
the MisesBot. The bot is an application
that uses the meta tags collected by the MetaParser (detailed in a future post)
as well as other available metadata to add tags to document.
- Cloud Control for ASP.Net – displays a list of hyperlinks in
varying styles depending on a weight.
- Toxi – the inspiration for the tag schema
- Freetag, an Open Source Tagging / Folksonomy module for
PHP/MySQL applications – the inspiration for the business logic layer
- Community Server – Inspired the tag browser interface and provided the banned words list.
- Did you notice the TagAuthority field in the tag
schema? A future version of the MisesBot
will automatically determine the “authoritative” document for each tag.
- Automatically mark up content. If we know the authoritative document for a
tag, we can automatically link to it when that tag appears in the document text.
- Improving the “related tags” algorithm. I could use some help with this:
Here is the query to get related tags. The problem is that it currently ranks tags according to their total popularity, not their “related-ness.”
CREATE PROCEDURE [dbo].[TagGetRelatedTags] @Tag VARCHAR(70) AS BEGIN DECLARE @TagId int SET @TagId = (SELECT TagId FROM Tag WHERE Tag = @Tag) SELECT TOP 30 Tag.Tag, COUNT(TagMap.TagId) AS 'Count' FROM TagMap INNER JOIN Tag ON TagMap.TagId = Tag.TagId WHERE [TagMap].TagId <> @TagId AND (TagMap.TagId IN (SELECT DISTINCT TagId FROM TagMap WHERE (ObjectId IN (SELECT ObjectId FROM TagMap WHERE (TagId = @TagId))) ) ) GROUP BY TagMap.TagId, Tag.Tag ORDER BY 'Count' DESC END
