Presenter: Misha Bouzinier
Task: Gain an understanding of natural language processing and the current state of the art
Approach: Discuss how InterSystems iKnow technology fits into the NLP ecosystem and complements the output of other components such as Lucene and Stanford NLP tools

A 101 session on Natural Language Processing that positions Intersystems tools in the broader ecosystem Problem: we’ve been touting “unstructured data” for five years, but many people both internally and externally still don’t know what it means to “process natural language” in general and how iKnow and our upcoming UIMA capabilities fit in this NLP ecosystem. This session will describe what a number of common technologies offer and how bare-bone NLP output typically needs to be complemented with more classic analytics or inference tooling to get the value out.

NewBie's Corner Session 15 Executing Routines and Labels

Welcome to NewBie's Corner, a weekly or biweekly post covering basic Caché Material.

Routines and Labels

Routines are computer programs with a number of executable code lines.

Labels (also called tags) are points in a routine that can be called (executed). They subdivide routines into manageable modules (or subroutines).

RESTful way of data transfer

This article gives a brief introduction how a RESTful service consumer and a RESTful service provider exchange data. It is a beginner’s guide. Data is transferred from a consumer to a provider as parameters of the service. Parameters are part of a service request. The result of the service action a response is returned from a provider to a consumer. Both the service request and response are standard HTTP messages. Since HTTP is a flexible standard regarding to the message contents, RESTful services also enjoy the versatility of data transfer methods.

NewBie's Corner Session 21 Parameters Part II

Welcome to NewBie's Corner, a weekly or biweekly post covering basic Caché Material.

Parameters

In the previous session we saw how to call RtnB from RtnA with Parameters.

We also defined Parameters as another name for Variables when used in passing data from one Routine to another, or, from one Label to another.

Calling a routine from a Label, or to a Label, from within a routine is very similar to calling a routine itself.

This is a list of all the posts in the Data Platforms’ capacity planning and performance series in order. Also a general list of my other posts. I will update as new posts in the series are added.

You will notice that I wrote some posts before IRIS was released and refer to Caché. I will revisit the posts over time, but in the meantime, Generally, the advice for configuration is the same for Caché and IRIS. Some command names may have changed; the most obvious example is that anywhere you see the ^pButtons command, you can replace it with ^SystemPerformance.

While some posts are updated to preserve links, others will be marked as strikethrough to indicate that the post is legacy. Generally, I will say, "See: some other post" if it is appropriate.

Capacity Planning and Performance Series

Generally, posts build on previous ones, but you can also just dive into subjects that look interesting.

Enterprises need to grow and manage their global computing infrastructures rapidly and efficiently while simultaneously optimizing and managing capital costs and expenses. Amazon Web Services (AWS) and Elastic Compute Cloud (EC2) computing and storage services meet the needs of the most demanding Caché based application by providing
 a highly robust global computing infrastructure.

Task: Build a development stack that enables state-of-the-art rapid development with a stable but adaptive back end.
Approach: Use InterSystems’ new document data model to achieve modern full-stack development

The MEAN stack is a very popular stack for building applications quickly that can change at a rapid pace. We will explore the benefits of such a stack and how you can tackle the requirements for modern and fast paced front-end development with support of a stable, but yet adaptive back-end using our new document data model.

Our company is looking for someone with expert object script skills and experience developing with REST using Caché. We have an existing application that currently supports a mobile application and a web application. The API is up and running but we need another developer to add new features and keep up with demand.

Experience with Amazon AWS is highly desired as the api is running on Windows in EC2. Familiarity with GitHub is also required.

Pay can be negotiated on a per hour basis after you provide an estimate for the time required to complete a given feature.

NewBie's Corner Session: 5 Operator Precedence

Welcome to NewBie's Corner, a weekly or biweekly post covering basic Caché Material.

Click on the Caché Cube in your system tray and select Terminal to try out the commands.

Order Precedence means the order in which mathematical operators are executed. In a Mathematical expression, you may have Multiplication, Addition, Subtraction, and Division. Which of these are executed first, second, third, etc.?

The basic Operator Precedence of mathematics is:

In previous articles on iKnow, we described a number of demo applications (iKnow demo apps parts 1, 2, 3, 4 & 5) that are either part of the regular kit or can be easily installed from GitHub. All of those applications assumed you already had your iKnow domain ready, with your data of interest loaded and ready for exploration. In this article, we'll shed more light on how exactly you can get to that stage: how you define and then build a domain.

Cross-origin Resource Sharing (CORS) is one of the basic security features built into browsers. CORS controls accessing resources from a HTML page in domains other than the original domain. It is particularly important for AJAX calls. Since RESTful services can be used as data provider to any AJAX call, you have to be able to control cross-origin access. By default services are not allowed to do CORS. You are going to learn how to enable it for Ensemble RESTful services.
