This is the third article in a series on iKnow demo applications, showcasing how the concepts and context provided through iKnow's unique bottom-up approach can be used to implement relevant use cases and help users be more productive in their daily tasks. Previous articles discussed the Knowledge Portal, a straightforward tool to browse iKnow indexing results, and the Set Analysis Demo, in which you can use the output of iKnow indexing to organize your texts according to their content, such as in patient cohort selection.

This week, we'll look into another demo application, the Dictionary Builder demo, in which we'll marry iKnow's bottom-up insights with top-down expertise, organizing our domain knowledge into dictionaries that are composed of the actual terms used in the data itself. Sticking to a top-down approach only, you'd risk missing out on some terminology used in the field that a domain expert sitting in his office wouldn't be aware of.

Sentiment Analysis is a thriving research area in the broader context of big data, with many small as well as large vendors offering solutions extracting sentiment scores from free text. As sentiment is highly dependent on the subject a piece of text is about (financial news vs tweets about the latest computer game), most of these solutions are targeted at specific markets and/or focus on a given type of source data, such as social media content.

This is the second article in a series on iKnow demo applications, showcasing how the concepts and context provided through iKnow's unique bottom-up approach can be used to implement relevant use cases and help users be more productive in their daily tasks. Last week's article discussed the Knowledge Portal, a straightforward tool to browse iKnow indexing results.

This week, we'll look into the Set Analysis demo, a slightly more advanced application where you'll be using the concepts identified by iKnow to organize your content into sets of documents. The original version of this demo was developed by Danny Wijnschenk & Alain Houf for an academy session at GS2015, but the app has evolved significantly since then.

InterSystems' iKnow technology allows you to identify the concepts in natural language texts and the relations that link them together. As that's still a fairly abstract definition, we produced this video to explain what that means in more detail. But when meeting with customers, what really counts is a compelling demonstration, on data that makes sense to them, so they understand the value in identifying these concepts over classic top-down approaches. That's why it's probably worth spending a few articles on some of the demo apps and tools we've built to work with iKnow.

In the first article in this series, we'll start with the Knowledge Portal, a simple query interface to explore the contents of your domain.

Is there a possibility to map a CSP page residing in namespace ABC to a namespace XYZ so you could access it as if executing from XYZ: http://localhost:57772/csp/xyz/MyPage.csp ? Some odd cocktail of web application and package mappings that could make this happen?

The idea is to keep the CSP page in sort of a read-only namespace that only contains code, with the data residing in another namespace. This works for zen pages, but not for CSP.

When refreshing a html or tablePane component using refreshContents() that takes a lot of server-side-processing, I'm running into timeouts every now and then. i.e., the result for the tablePane is that there's nothing displayed at all.

How can we configure (relax) that timeout so also those heavier ones get refreshed eventually? Just overriding %request.Timeout in %OnPreHTTP did not seem to do the trick.

iFind Search Portal

A simple and rather automated search portal leveraging iFind capabilities for rich text search in 2016.1. It has simple faceting, result ranking, highlighting of search results etc and just works off any table you point it to that has an iFind index by appending ?t=MyPackage.TableName to the URL.

See also https://github.com/bdeboe/isc-iknow-ifindportal for more details and the latest version.
