KNIME (/naɪm/), the Konstanz Information Miner,[2] is a free and open-source data analytics, reporting and integration platform. KNIME integrates various components for machine learning and data mining through its modular data pipelining "Building Blocks of Analytics" concept. A graphical user interface and use of JDBC allows assembly of nodes blending different data sources, including preprocessing (ETL: Extraction, Transformation, Loading), for modeling, data analysis and visualization without, or with minimal, programming.[citation needed]

Since 2006, KNIME has been used in pharmaceutical research,[3] and in other areas including CRM customer data analysis, business intelligence, text mining and financial data analysis. Recently, attempts were made to use KNIME as robotic process automation (RPA) tool.[4][when?]

KNIME's headquarters are based in Zurich, with additional offices in Konstanz, Berlin, and Austin (USA).[citation needed]

History[edit]

Development of KNIME began in January 2004, with a team of software engineers at the University of Konstanz, as an open-source platform. The original team, headed by Michael Berthold, came from a Silicon Valley pharmaceutical industry software company. The initial goal was to create a modular, highly scalable and open data processing platform that allowed for the easy integration of different data loading, processing, transformation, analysis and visual exploration modules, without focus on any particular application area. The platform was intended to be a collaboration and research platform and also serve as an integration platform for various other data analysis projects.[5]

In 2006, the first version of KNIME was released. Several pharmaceutical companies started using KNIME, and a number of life science software vendors began integrating their tools into the platform.[6][7][8][9][10] Later that year, after an article in the German magazine c't,[11] users from a number of other areas[12][13] joined ship. As of 2012, KNIME is in use by over 15,000 actual users (i.e. not counting downloads, but users regularly retrieving updates) in the life sciences and at banks, publishers, car manufacturer, telcos, consulting firms, and various other industries, and a large number of research groups, worldwide.[citation needed][needs update] Latest updates to KNIME Server and KNIME Big Data Extensions, provide support for Apache Spark 2.3, Parquet and HDFS-type storage.[citation needed]

For the sixth year in a row, KNIME has been placed as a leader for Data Science and Machine Learning Platforms in Gartner's Magic Quadrant.[citation needed][year needed]

Internals[edit]

KNIME allows users to visually create data flows (or pipelines), selectively execute some or all analysis steps, and later inspect the results, models, using interactive widgets and views. KNIME is written in Java and based on Eclipse. It makes use of an extension mechanism to add plugins providing additional functionality. The core version includes hundreds of modules for data integration (file I/O, database nodes supporting all common database management systems through JDBC or native connectors: SQLite, MS-Access, SQL Server, MySQL, Oracle, PostgreSQL, Vertica and H2), data transformation (filter, converter, splitter, combiner, joiner), and the commonly used methods of statistics, data mining, analysis and text analytics. Visualization is supported with the Report Designer extension. KNIME workflows can be used as data sets to create report templates that can be exported to document formats such as doc, ppt, xls, pdf and others. Other capabilities of KNIME are:

  • KNIMEs core-architecture allows processing of large data volumes that are only limited by the available hard disk space (not limited to the available RAM). E.g. KNIME allows analysis of 300 million customer addresses, 20 million cell images and 10 million molecular structures.
  • Additional plugins allow the integration of methods for text mining, image mining, as well as time series analysis and network.
  • KNIME integrates various other open-source projects, e.g., machine learning algorithms from Weka, H2O.ai, Keras, Spark, the R project and LIBSVM; as well as plotly, JFreeChart, ImageJ, and the Chemistry Development Kit.[14]

KNIME is implemented in Java, allows for wrappers calling other code, in addition to providing nodes that allow it to run Java, Python, R, Ruby and other code fragments.[citation needed]

License[edit]

As of version 2.1, KNIME is released under the GPLv3 license, with an exception that allows others to use the well-defined node API to add proprietary extensions.[15][needs update] This allows also commercial software vendors to add wrappers calling their tools from KNIME.

KNIME Courses[edit]

KNIME allows the performance of data analysis without programming skills. Two lines of online courses are provided, based on Data Wrangling and Data Science.[16]
