KNIME Verified Components

Easily reuse bundled functionalities, verified by KNIME experts.

A set of Components that behave like KNIME nodes, including error handling capabilities, which are developed by KNIME and regularly released on the KNIME Community Hub. We'll regularly update this page with new Components - here are the most recent ones:

Topic Explorer View

This component generates a view to visualize the output of a topic model. You can use it to browse topics, their terms, semantic/exclusivity scores and documents. It can be deployed as a data app on KNIME Business Hub or KNIME Server. To see how to combine it with other nodes and verified components check the Topic Modeling space.

Topic Explorer View

Topic Extractor and Assigner (STM)

These two twin components can be adopted to train and test a Structural Topic Model (STM) via the KNIME Interactive R Statistics Integration. The component adopts the KNIME Conda Integration to automatically install the environment on the first component execution. To see how to combine it with other nodes and verified components check the Topic Modeling space.

Topic Scorer (Labs)

This component is designed for scoring topics at the output of a topic model. The experimental component measures semantic coherence, exclusivity and neighbor distances of one or multiple models. The component is part of KNIME Labs as it is an experimental implementation. To see how to combine it with other nodes and verified components check the Topic Modeling space.

Verified Component Categories

Verified components are officially released by the KNIME team and are divided into the following categories. Explore all the verified Components in each category on the KNIME Hub.


Automation Components help when a workflow has to be executed in a production environment in an automated fashion - from complex AutoML to simple tricks to increase flexibility and traceability of your workflow.

Data Manipulation

When dealing with raw data, there are recurrent data manipulation techniques requiring complex workflows. We offer those workflows via Components to quickly clean, rename, filter, and transform raw data columns.

Finance Analytics

Finance teams across all industries require specific techniques to keep track of the company’s numbers while ensuring precision and compliance. Those time-consuming tasks usually rely on data from different spreadsheets, which can be hard to maintain and update. These Components help build reusable workflows for an efficient financial analysis.

knime_icons_rz Guided Analytics

Components can generate views when using Widget and JavaScript nodes. Those views can be used on their own or in sequence to interactively guide the user through the analysys. Use the Guided Analytics Components to create guided analytics workflows for local usage or remote access via KNIME WebPortal.

Life Sciences

Gather and analyse Life Science data with shared Components. For example, extract data from the European Nucleotide Archive, ChEMBL or PDB or perform a Pathway Enrichment Analysis by simply dragging and dropping the Component of your choice.

knime_icons_rz Model Interpretability

Training performant predictive models often leads to black boxes: data goes in the box, it's processed by nearly incomprehensible algorithms, predictions come out of the box. KNIME offers an extension to be combined with these Components for Machine Learning Interpretability (MLI) and Explainable AI (XAI) use cases.

Text Processing

The text processing Components help you to analyse text documents - from extracting data from biomedical literature, to document preprocessing, through to computing document similarity.

knime_icons_rz Time Series

Easily clean, aggregate, visualize, and forecast time series data with this set of Components. Includes options for seasonality visualization and removal, ACF and PACF plots, as well as ARIMA forecasting.

Countless visualizations exist to display data in colorful charts. Most of those visualizations are already provided in KNIME via JavaScript and Plotly nodes. If you cannot find the plot you need as a standard node, make sure to check this category of Components with more complex visualizations or interactive composite views.

What are Components?

Components are really KNIME nodes that you create with a KNIME workflow, enabling you to easily bundle, reuse, and share functionality. Configuration and widget nodes allow you to create Components that behave just like normal nodes with a logo, a dialogue, and often interactive views. With KNIME Analytics Platform, anyone can create Components and share them, via the KNIME Hub, with the community.

Community Components Collections

Seasonal reviews of community components are published on KNIME Blog. Components really are KNIME nodes that you create with a KNIME workflow. Note that these components are built by and for the community via the KNIME Hub. These components have not been officially verified by the KNIME team.
