Overview
A large majority of medical data is stored as text, usually across a number of document types and storage locations. This unstructured content embedded in patient records can be tapped for a wealth of greater knowledge with HLA’s deep-dive search and analytics engines.
HLA technology has been developed to utilise unstructured clinical text through a range of functions including:
Report Classifying
Content Extraction
Inferencing
Keyword & Concept Search
Hot Key Abstracting & Coding
HLA’s technology uses semantics (i.e. the meaning of a word, phrase, sentence) and context (document structure and surrounding text) to identify a broad range of medical concepts within medical documents.
Our unique “Knowledge Discovery – Knowledge Reuse” methodology ensures that all knowledge captured in the creation of a client’s solution is integrated immediately into their technology. This enables rapid iteration to an optimal solution for their needs.
The HLA Wheel diagram shows the structure of our technology hub and the Language Technology Hub Applications table expands on the clinical and business uses of the various segments of the wheel.

Description/Example |
Report Classifier |
Document Separation |
Separating documents based on defined classes (e.g. separating cancer from non-cancer reports). |
Work Streaming |
Filter documents and route to correct staff or user-groups for processing (e.g. filter breast cancer reports from other tumour streams). |

Ensure that all content that forms a complete record is included and flag missing content (e.g. flagging that |
Report Consistency Validation |
Billing Errors & Omissions |
Automatic computation of billing codes lowers errors and increases the number of chargeable items. |
Unexpected Results |
Ensure that content is consistent across a report (e.g. alerting a radiology report that has a diagnosis that is unexpected in the context of the requested investigation). |
|
Hot Key Coding & Classification |
Medical Records Coding |
Add-on application that automatically suggests clinical codes for any on-screen content (e.g. suggesting codes in a pop up for a Discharge Summary in an EMR system). |
GP Coding |
Code specific types of content (e.g. codifying reason for attendance at a General Practice or Emergency Department). |
