Many web publishing systems allow content to be “tagged” with keywords. For example, a Sitebuilder page may be given one or more tags. Similarly a blog entry is classified using tags. Social bookmarking systems like del.icio.us use keyword tagging. Bibliographical databases also commonly use taxonomies of keywords. Most of these systems can be searched using keywords. Many of these search interfaces can be accessed programmatically.
Most keyword tagging and searching systems, such as that used in Sitebuilder, are not taxonomical. There is no taxonomical structure to which an author or researcher can refer when tagging resources or searching for resources.
I have identified a set of real use cases in which a taxonomical approach to keyword searching would be beneficial. These cases also imply that resources are tagged according to the keywords available in the taxonomy.
Here is a description of how the tool could work:
The search interface contains a tree structure representing the taxonomy of keywords.
The tree structure can be explored, drilling down through its branches.
Individual keywords, or whole branches of keywords can be selected.
There is also a text box allowing the user to type in keywords (with autosuggest giving options as they type).
As keywords are selected, they are listed in a text area showing all currently selected search terms.
Once all of the required keywords have been chosen, a search is done, returning a list of all matching resources.
The search could be ordered in several different ways, for example with resources that have a higher match coming at the top of the list.
Here is an illustration of how the interface might work (it doesn’t yet do the search):
Configuring the taxonomy
The taxonomy could be stored as an xml file on the web (for example in the same location as the search tool).
The xml file could be hand coded, or the search tool could provide an interface for creating a taxonomy file and editing its tags.
The taxonomy file to be used could be specified by the author of the web page on which it appears.
The end user could be allowed to choose a taxonomy file, it could be possible to search for taxonomy files in Sitebuilder.
Configuring the sources
The search tool will need to know about the web application in which resources are stored (for example Sitebuilder).
It will need a method for searching each web application (how to build the search url).
One or more sources could be specified by the author of the page on which the tool is deployed – it could be set to search Sitebuilder, Blogs, etc.
A version of the tool could be made available allowing the end user to choose sources.
Saving and sharing searches
Searches could be saved onto the end users local machine (Shared Object in Flash, filesystem in AIR).
Searches could also be shared with other users.
Using the taxonomy to tag resources
The search tool could be used to assist in tagging resources using a selected taxonomy.
For example, a user selects a series of keywords, and the tool displays the text to paste into the keyword tag field of the Sitebuilder page properties.

I’m gonna do this….
2) The search tool can load its tagxonomy from an xml file stored on the web.
3) I’m going to add a feature that allows different tagxonomies to be loaded as required. If the xml files are stored in Sitebuilder and tagged as “tagxonomy” then the search tool could even auto-discover tagxonomies for the user to choose from.
4) A tagxonomy file could also be tagged with the unique identifier of a person, group or department (using the web groups codes for these), thus associating the file with the profile.
5) I could allow for the tagxonomy to be edited in the search tool (adding new tags or tag collections for example).
6) The tagxonomy could then be uploaded onto Sitebuilder, if the user has permissions, it could replace an existing tagxonomy, if not they can create their own new tagxonomy.
7) It will also be possible to select a series of tags from the tree, and have an string automatically generated from that. The string can be pasted into any content tagging application. Importantly, the string should include tags that identify the tagxonomy from which the tags where taken.
Best of all, i’ll try to build it as an Adobe AIR desktop application (not sure how Single Sign On will work with that).
I reckon that will take a few weeks to build (as I’m in the middle another big project).
This example will load the tags defined for the Renaissance Studies project:
