Natural Language Processing

The Challenge

Circlebase : Unstructured data challenges.

Most healthcare data is unstructured and resides in diverse formats (clinician notes, scanned documents, images, audio files to name a few) making it difficult to leverage this data to gain insights that improve patient care. unlocking the value of this information computationally through natural language processing (NLP) is of paramount value in advancing healthcare for humans.

This is compounded by the language variation across clinical specialties.

Conventional access to healthcare data is document-centric and requires reading the documents manually to find information. This approach is rife with errors, is time-consuming leading to missing data.

A solution that simplifies and unleashes

Our NLP platform takes you on the path towards a data-centric view. It uncovers intelligent health outcomes by harmonizing the structured, unstructured, and missing data. The result? Our solution outperforms manual and similar automation options significantly.

NLP in Healthcare and Life Sciences Market worth $4.3 billion by 2026


Our platform offers data extraction, lexical and semantic analysis, Named-Entity Recognition (NER), Assertion Status Detection, Relation Extraction, tagging and annotation, normalization, and visualization.

The output can be then fed into applications, visualization tools, AI/ML, and other platforms that make it easy to share and compare results and use the information to derive intelligent health outcomes.

Where our NLP platform truly shines is understanding the different ontologies used to categorize similar things, group them, and provide synonyms for concepts. For example, cancer, carcinoma, and neoplasm all refer to the same concept, so grouping this data and avoiding duplicates is one of the essential capabilities our platform brings.

The platform offers a custom annotation tool by which our domain specialists constantly curate the data and provide feedback to the model in terms of data correctness and accuracy. This enhances the automation and ensures correctness.

To add power to the automation and ensure correctness shown below is an overview of Circlebase’s NLP platform.
