23 Things: The Third Tool = Blog Directories/More on Tagging

In my previous post on social bookmarking, I mentioned "tagging." This refers to the process of adding descriptive terms to online content, like a bookmark you save in del.icio.us, a photo you upload, or a post you contribute to a blog. When everyday language is used in tagging, it is referred to as a "folksonomy."

I use tags to describe posts in both of my blogs. In Forced Migration Current Awareness, I select tag terms from the International Thesaurus of Refugee Terminology. So these tags are the same as controlled subject terms used in library catalogs and many research databases. However, in this blog, Researching Refugees, the focus of the posts is on web technologies and therefore not adequately covered in the refugee thesaurus. So I employ folksonomy instead, i.e., everyday language that is better able to describe current concepts (like "blogs," "RSS," "social bookmarking," etc.).

Tags are a useful way to browse or search for relevant content. For example, you might want to see which of my blog posts relate to the "safety of humanitarian personnel." You can also use a blog search engine like Technorati to search tags across blogs; these are the results retrieved when I searched for posts tagged "refugees."

Not everyone uses tags to describe their blog posts, though. So if you want to find out which blogs have posted on forced migration issues or if you want to locate blogs whose main focus is forced migration, you can search Technorati more generally. Google Blog Search is another way to find relevant posts and/or blogs.
