KNIME

KNIME is a powerful, user-friendly graphical workbench which can be used for the entire data analysis process. The open integration platform provides over thousand nodes and except for the data mining, KNIME can be used for text mining and sentiment analysis. The KNIME text processing plug-in with its numerous features enables data expert to read, manipulate and quantify texts  in a comprehensible way. The proccess of text and sentiment analysis usually includes steps of textual data acces, data transformation, sentiment analysis, visualization and reporting. Robust big data extensions are available for Hadoop, so that big quantities of textual data can be accessed and analyzed.

KNIME text processing provides functionality from natural language processing, text mining and information retrieval. By means of text processing functionality, textual data can be read, represented as documents and terms, so several tagging filters, data structure transformations and other preprocessing tasks can be applied to textual data. Text processing feature is developed to read and process textual data and transform it into numerical data in order to apply regular KNIME data mining nodes, but except regular nodes, corpus or subjectivity lexicon can be applied to analyze and evaluate textual data.

Sentiment analysis depends on the corpus or lexicon that understands the relative context or a grade of a word or expression, so it is both language and context specific. The corpus built for sentiment analysis  can be applied to preprocessed textual data in a way that data can be categorized and scored, giving the final analysis score on the level of single text document or on the level of the whole entity or object which is analyzed.
