Corenlp write a custom annotator

Humphrey Sheil's blog covering software engineering design and technology JEE. Monday, October 06, Named Entity Recognition - short tutorial and sample business application A latent theme is emerging quite quickly in mainstream business computing - the inclusion of Machine Learning to solve thorny problems in very specific problem domains.

For me, Machine Learning is the use of any technique where system performance improves over time by the system either being trained or learning. In this short article, I will quickly demonstrate how an off the shelf Machine Learning package can be used to add corenlp write a custom annotator value to vanilla Java code for language parsing, recognition and entity extraction.

In this example, adopting an advanced, yet easy to use, Natural Language Parser NLP combined with Named Entity Recognition NERprovides a deeper, more semantic and more extensible understanding of natural text commonly encountered in a business application than any non-Machine Learning approach could hope to deliver.

Machine Learning is one of the oldest branches of Computer Science. From Rosenblatt's perceptron in and even earlierMachine Learning has grown up alongside other subdisciplines such as language design, compiler theory, databases and networking - the nuts and bolts that drive the web and most business systems today.

But by and large, Machine Learning is not straightforward or clear-cut enough for a lot of developers and until recently, its' application to business systems was seen as not strictly necessary.

For example, we know that investment banks have put significant efforts applying neural networks to market prediction and portfolio risk management and the efforts of Google and Facebook with deep learning the third generation of neural networks has been widely reported in the last three years, particularly for image and speech recognition.

But mainstream business systems do not display the same adoption levels. Dramatic reduction in error rate on Switchboard data set post introduction of deep learning techniques. Luckily you don't need to build a deep neural net just to apply Machine Learning to your project!

Instead, let's look at a task that many applications can and should handle better - mining unstructured text data to extract meaning and inference.

Natural language parsing is tricky. There are any number of seemingly easy sentences which demonstrate how much context we subconsciously process when we read. For example, what if someone comments on an invoice: INV is for the balance.
