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 automatic document classification : Part 1

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!

If you are still classifying documents manually, analyzing their content, and sorting them into categories, you might be interested in finding out how you can extend Alfresco to automatically classify your documents for you.

Getting started with Alfresco

During my internship at TGR, one of the project's requirements was indexing and managing documents, and that was my first experience with Alfresco,  which is an open source Enterprise Content Management (ECM), it combines a collection of content-centric technologies like Document Management (DM), Records Management (RM), and other technologies that should make your life, if your field of work is Content Management, easier.

Customizing Alfresco can be a bit tricky, and hard to grasp at first, but after doing it few times, you start to get the feel of it, and this post, as well as the future articles about Alfresco, are all here for you to get there.

smart Card tutorial : Part 1

When your application handles or performs sensitive data or operations, security becomes a major concern, which is why some companies decides to use Strong Authentication for their applications, also known as 'two factors authentication' : one thing that you have (the smart Card, or USB token), and one that you know (the PIN or password).

This article will be the start of a series of tutorials about smart cards (USB Tokens are readerless smartcards, so the same applies) : how to access, manage, generate keys etc... at the end of the articles, tou should be able to write smart-card-based applications for authentication, digital signatures and PIN/PUK management.

Java JNDI Tutoriel : Ldap query

Our topic of discussion today will be JNDI (Java Naming and Directory Interface), which is a standard way to query directories for different kind of available informations.

We will see how you can use Java to interact with OpenLdap or any other directory (like Apache OpenDS etc...).

In order to connect to an ldap directory server we will need to know :

• The server url (in our case localhost)
• The authentication used : Simple, Digest etc...
• the base DN, or the root element.
• Bind DN, the user we will connect to the directory as.
• Bind password.

Presenting EJBCA

Your enterprise decided recently to start using digital Certificates for authentication, digital signatures, Server authentication etc... in other words, you need a Certificate Authority(CA) in order to deliver certificates for your servers and users.

Of course, you can choose to buy certificates from known vendors like VerSign,Thawte etc... but you will need to pay for every certificate a user or a server needs! a better approach would be hosting you own In-House certificate Authority, this way you can issue as many certificates as you need.
Now that you decided to host your own CA,have your own Public Key Infrastructure (PKI),
