Interwoven has built its name on Web content management, so its no surprise that its categorization product—MetaTagger 3.0—is tightly integrated with the Interwoven TeamSite content management platform (see screen).
This is both positive and negative, however. Negative, because only companies that are already using or are planning to implement TeamSite will be able to use MetaTagger. Positive, because although almost all categorization tools can integrate with content management applications, few have the same level of integration that MetaTagger has with TeamSite.

To run MetaTagger, we had to first install TeamSite, which runs on Windows server platforms and Solaris. TeamSite was easy to install, especially for a content management system, and we were soon up and running.

Much of the initial setup of MetaTagger—including taxonomy configuration and the designation of training sets—is done by editing XML-based configuration files. Taxonomies can also be derived from directory structures. Using the MetaSource Editor client, we could easily view, customize and fine-tune category taxonomies.

Once everything is set up, MetaTagger can be accessed from the browser-based administration interface or from the command line.

Legacy content can be categorized through the use of a command-line batch tool, but the main focus of MetaTagger is categorizing and correctly tagging content as it is created. In both our own tests and in the results generated by Interwoven, we could see how users inside TeamSite could leverage MetaTagger to effectively categorize content as it entered the content management system.

Within the TeamSite interface, we could easily view all category and taxonomy information. It was very simple to accept suggestions and make necessary changes, and if edits changed content, we could generate categories on the fly.

In addition to using categories from a taxonomy, MetaTagger can suggest related topics pulled from 4,600 terms. In tests, this proved useful for determining keywords for Web content, and MetaTagger did a good job of managing some nontraditional content such as multimedia files.

With multimedia files that have good built-in tagging, such as MP3 files, MetaTagger can pull information directly from the file. It is also possible for authors to directly relate multimedia content to specific categories.

Any company interested in MetaTagger has probably already made a six-figure investment in the TeamSite content management system. MetaTagger costs from $85,000 to $110,000 per server, depending on the customer deployment.
