Release Notes for Mindbreeze InSpire
Version 22.3

Innovations and new features

WCAG Certification

Mindbreeze was awarded the silver certificate for web accessibility by the WACA initiative and the independent certification body TÜV Austria.

As a representative sample for the Mindbreeze InSpire cloud search web application, a use case in German and English language was selected for the certification audit. Mindbreeze meets the requirements of WCAG 2.1 - AA to a high degree and therefore received the silver certificate.

The following criteria must be met for the Web Accessibility Certificate (WACA) in Silver:

Website meets WCAG 2.1 - AA success criteria to the greatest extent possible.

All content is accessible to all users.

Basic functionality is fully accessible to all users.

Parts of the extended/optional functionality are more cumbersome for some users, but still accessible.

WACA is Austria's first and only seal of quality to represent web accessibility according to the international W3C guidelines. The certificate of the WACA initiative and the independent certification body TÜV Austria is intended to ensure accessibility for all people on the professionally tested website.

Extended Relevance Model for Insight Apps

Mindbreeze InSpire now supports user defined document boosting rules where the boost factor itself can take the form of a property expression. Therefore, document boost factors can be computed given document metadata and even based on graph expressions using references.

This feature can be used to improve the relevance and accuracy of search results in Mindbreeze Insight Apps and enables completely new application possibilities.

As a concrete example we would like to include the priority (priority.value – 1 for cirtical up to 5 for planning) and the classified severity (severity.value – 1 for high up 3 for low) in the relevance of ServiceNow tickets. Both properties are more critical the lower the value they have. As new computed boost factors we can use the following expressions:

To boost priority:1 + (1 - priority\.value) div 4.0
To boost severity: 1 + (1 - severity\.value) div 2.0

Object Recognition Based on InceptionV4

The new InceptionImageFilter plugin allows classifying images using Deep Learning. The plugin allows to collect, filter and search images and thumbnails in new ways.

For the object recognition the Inception V4 model is used, which is a very well-known and successful architecture for Convolutional Neural Networks related to image classification and object detection. In the filter-plugin configuration, you can further customize the filter for your application purpose.

New and Advanced Connectors

Box Connector

The new Box connector enables indexing all content from a Box Cloud instance. This allows, for example, text documents, images, videos, notes, etc. to be indexed by Mindbreeze InSpire and used within Mindbreeze Insight Apps.

In conjunction with the new Box Principal Resolution Service, it is possible to download and resolve user and group permissions from your Box Cloud instance.

Microsoft Graph Connector Supports Profile Endpoint

With the inclusion of new user profile endpoints, it is now possible to index advanced information about users/people from your Sharepoint Online, Office 365 and OneDrive cloud instances through the Microsoft Graph Connector. This enables new and improved search applications for a 360-degree view of projects, experts and skills in an organization.

The newly available profile-metadata includes:

Schools and education

Skills and expertise

Interests and hobbies

Projects

The additional metadata is automatically downloaded with the new version of the Microsoft Graph connector if the corresponding configuration option "Get Metadata From Profile", is enabled.

Microsoft Graph Connector for Search-Based Organization Charts

Using new API endpoints in Microsoft Graph, it is now possible to index the responsible supervisor/manager of a user/person as a metadata reference using the Microsoft Graph connector. This metadata reference can be used to generate hierarchical organization diagrams in a Mindbreeze Search app.

In the following example, you can see such a generated organization chart view in a Mindbreeze InSpire Insight App:

Revised Microsoft Dynamics (CRM) Connector

New optimizations in the Microsoft Dynamics (CRM) connector bring significant performance improvements for large data volumes. With over 1 000 000 simulated test documents, download speeds are now up to 10 times faster than before.

The flexible data structure in Microsoft Dynamics, together with Mindbreeze InSpire, offers a variety of different search applications.

Technical Advancements

Insight Engine Query Performance Improvements

Software optimizations and adjustments to the CPU settings in the operating system, significantly improved the query performance of the Insight Engine. In our "General Web Index" benchmark, we were able to determine an average performance increase of 25%.

New Installer and Image Format

With 22.3, there is a new self-describing image format that is specifically designed to modularize the installation process.

The image format is verified and loaded by the InSpire System Loader. It is a repository consisting of container images alongside update instructions. Additional components, such as the host operating system update, are also part of the image.

The "InSpire System Manager" service is used for performing the update. If a more recent System Manager is part of this image, it is replaced by the Loader so that the new Manager can be used to perform the update. After the update, the System Loader is also updated, if it is part of the image.
