automatic document classification with Alfresco Part 2

In the first part of this article, i explained how you can use Lucene to query a document (Word, PDF etc...), and find matches for specific keywords, which was necessary for us in order to automatically identify the document's category based on its content.

We've chosen a simple approach to demonstrate the automatic classification extension : if a document contains the name of a category, then it belongs to it, of course we can use other approaches like assigning multiple keywords to a category, example : if a document contains one of the following words "java, .Net, c#..." then assign it to category "Software development", it can easily be implemented once you finish reading and understanding this article, and of course how you implement it depends on your specific needs, you might need some more advanced classification algorithm.

Alfresco is capable of handling multiple classifications, or hierarchies of classification, it's a very useful feature, and can make your life a lot easier when looking for documents, especially the ones with no indexed content like pictures, scanned documents etc...

Classifying a document in Alfresco can be as easy as few clicks on the browser, however it can be very time-consuming process if you are uploading many documents every day, or if you are migrating to Alfresco : Imagine having to manually classify a few thousands of documents!
