A Quick Tour Of Ephesoft

by Clifford Laurin Ike Kavas Michael Muller Pat Myers | September 2012 | Open Source

Ephesoft has two user interfaces. One is intended for use by operators to review and validate Ephesoft's classification, separation, and extraction. The other is intended for use by system administrators in the configuration of Ephesoft. Not all aspects of Ephesoft can be configured through the administrative interface, however. For some of the configuration, administrators will need to use a text editor to modify files in Ephesoft's installation directory.

Before we begin, it is helpful to understand some commonly-used terms. A batch or a batch instance is a set of document images that are processed together. A batch class is a set of rules for processing a batch.

This article by Pat Myers, Ike Lavas, Michael Muller, and Clifford Laurin, authors of Intelligent Document Capture with Ephesoft, will provide you with a brief introduction to Ephesoft's user interfaces:

  • The administrative user interface
  • The operator user interface

About Cassandra

by Nishant Neeraj | October 2013 | Open Source

This article by Nishant Neeraj, author of Mastering Apache Cassandra, will describe Cassandra to be distributed, decentralized, fault tolerant, eventually consistent, linearly scalable, and a column-oriented data store. This means Cassandra is made to easily deploy over a cluster of machines located at geographically different places. There is no central master server, so no single point of failure, no bottleneck, data is replicated, and a faulty node can be replaced without any downtime. It's eventually consistent. It is linearly scalable, which means with a greater number of nodes, the requests served per second per node would not go down. Also, the total throughput of the system will increase with each node being added. And finally, it's column oriented, much like a map (or better, a map of sorted maps) or a table with flexible columns where each column is essentially a key-value pair. So, you can add columns as you go, and each row can have a different set of columns (key-value pairs). It does not provide any relational integrity. It is up to the application developer to perform relation management.

Access Control in PHP5 CMS - Part 1

by Martin Brampton | January 2009 | MySQL Content Management Open Source PHP

Many websites will want to control who has access to what. Once embarked on this route, it turns out there are many situations where access control is appropriate, and they can easily become very complex. So in this two part article by Martin Brampton, we look at the most highly regarded model–role-based access control (RBAC)–and find ways to implement it. The aim is to achieve a flexible and efficient implementation that can be exploited by increasingly sophisticated software. To show what is going on, the example of a file repository extension is used.

Accessing and using the RDF data in Stanbol

by Reto Bachmann-Gmür | July 2013 | Open Source
