In ECM, taxonomies ensure that content is accurately cataloged and easily accessible. Having consistent and reliable access to unstructured content is the foundation to realizing the business benefits of ECM, and all subsequent content-centric enterprise applications will realize their return on investment (ROI) by leveraging this essential capability.
IBM Classification Module automates the process of categorizing your content by reading and analyzing the full text of each document. It analyzes the entire document, discerns the topics in the text, and then assigns it to a proper category. And it won't be fooled by noises in your content, such as misspellings, abbreviations, or short-hand or technical terms. Moreover, the IBM Classification Module adapts to the unique nature of your business by learning to identify different categories from examples you provide to it. And as you provide feedback on its performance, it adjusts in real time, immediately taking into account corrections you have made. In this way, its accuracy keeps pace with your business, rapidly adjusting to changes as they occur.
The IBM Classification Module integration for IBM FileNet P8 can be deployed on Windows®, AIX®, Solaris, and Linux® environments. The example in this article is specific to the integration on a Microsoft® Windows platform. However, the key concepts and information provided are relevant to any platform.
Integration architecture overview
IBM Classification Module for IBM FileNet P8 is a system that automatically classifies new content for insertion into IBM FileNet P8, or filters out content that doesn't fit the profile of managed content. It can also reclassify and move existing P8 documents to the correct folders or document classes. Unlike other classification systems that are based on rules only, the Classification Module is based on a combination of text analysis and rules, and incorporates real-time learning that adapts to changing business needs and becomes more accurate over time.
Figure 1. Integration architecture overview
As shown in Figure 1, at the core of this solution is the IBM Classification Module product that has been in the market place for many years and has proven to be scalable and reliable in demanding IT environments. It consists of three core components as follows:
- Classification Application Program Interface (API)
The Classification API provides C, Java™, .NET, or COM client API libraries to enable rapid development of various client applications that interact directly with the Classification server component.
- Classification server
Embedded with natural language processing capabilities, the Classification sever classifies free-form texts by leveraging its Relationship Modeling Engine and a predefined knowledge base (KB) in decision making.
- Classification Workbench
Classification Workbench allows you to create and analyze a knowledge base, evaluate the KB's performance using reports and graphical diagnostics, and work with a collection of texts or messages known as a corpus for analysis, training, and learning.
In addition, the Taxonomy Proposer is a new tool shipped with Classification Workbench 8.5. It can assist users in creating a taxonomy starting from scratch or from a partial one, where it uses custom clustering algorithms to analyze and group similar documents together.
On top of the core product is the newly added integration asset for providing a taxonomy automation solution to IBM FileNet P8. The integration for IBM FileNet P8 includes the following components:
Automatically classifies and filters out documents, and sets aside a configured percentage of documents for audit and manual review.
- Classification Review Tool
A browser-based application that enables online learning by manually confirming or correcting automatic classification.
- Content Extractor
A command-line tool that extracts sample content from the IBM FileNet P8 repository to train a KB and enable automatic classification.
Integration and classification workflow
The example in this article shows you how to first deploy IBM Classification Module integration for IBM FileNet P8, and then perform the content classification in the integrated environment by following the workflow displayed in Figure 2.

To add IBM FileNet P8 folders and document classes:
Important:The folder and document class names that you define here in IBM FileNet P8 object store must match the names specified in the ECM Classification tools (that is, Content Extractor, Classifier, and Classification Review Tool). If you change a default name, be sure to update it in both locations.
- Create the folders in IBM FileNet P8. Use the default names listed below or specify your own.
Figure 1-2-5. Folders for IBM FileNet P8
- Create the document classes in IBM FileNet P8. Use the default names listed below or specify your own.
The document classes are required only if you plan to classify documents by document class.
Figure 1-2-6. Document classes in IBM FileNet P8
To configure connectivity between IBM Classification Module and IBM FileNet P8:
- Configuring connectivity to IBM FileNet P8 depends on factors such as the IBM FileNet P8 version, Java
Web application, and client-server communication. Configuring connectivity might be as simple as specifying the IBM FileNet
P8 IP address in the WcmApiConfig.properties file in F:\IBM\ICM\ECMTools\conf.
Here is an example of what this file would look like. Substitute the IP address and port number of your FileNet P8
server in the first three lines. Consult your FileNet P8 administrator if you are unsure what the correct URL is.
RemoteServerUrl =http://220.127.116.11:8008/ApplicationEngine/xcmisasoap.dll RemoteServerUploadUrl =http://18.104.22.168:8008/ApplicationEngine/doccontent.dll RemoteServerDownloadUrl =http://22.214.171.124:8008/ApplicationEngine/doccontent.dll CredentialsProtection =Clear CryptoKeyFile =C:\\Program Files\\FileNet\\Authentication\\CryptoKeyFile.properties CredentialsProtection/UserToken = Symmetric CryptoKeyFile/UserToken =C:\\Program Files\\FileNet\\Authentication\\ UTCryptoKeyFile.properties
Configuring connectivity might also involve additional configuration files and communication library files (JARs).
Phase 2. Train the IBM Classification Module System with IBM FileNet P8 content
This section uses step-by-step screen shots to illustrate how to train an IBM Classification Module system, and have it learn how to classify based on the sample content extracted from IBM FileNet P8 through three tasks below:

This article introduced IBM Classification Module and IBM FileNet P8 integration steps in a Windows environment. It first reviewed the integration architecture and workflow. It then used step-by-step screen shots to illustrate how to use the IBM ECM Classification tools along with the IBM Classification Module server component and the Classification Workbench to automate the content classification in the integrated environment.
In summary, while ingesting new content into IBM FileNet P8, a typical workflow to automate content classification in the integrated environment is:
- Train the IBM Classification Module system with IBM FileNet P8 content by using the Content Extractor to extract sample content from a
FileNet P8 repository, creating and analyzing a knowledge base in the Classification Workbench, and registering the newly created KB with the
classification engine through the Classification Manager.
You can rapidly train the IBM Classification Module based on the categories already created in your IBM FileNet P8 repository, as addressed above. But if you don't have a set of categories ready to go, the IBM Classification Module's taxonomy proposer can divide an existing set of content into logical groupings, recommending a new set of categories and corresponding names. You can learn more about the Taxonomy Proposer by referring to the Integration for IBM FileNet P8 User's Guide.
- Classify new content for IBM FileNet P8 by using the Classifier tool to classify documents into right folders or document classes in FileNet P8, reject documents with low relevancy scores, and set aside a configured percentage of documents for manual review or audit.
- Review content classification to ensure the classification accuracy by using the Classification Review Tool to manually confirm or correct automatic classification.
