i am a new user of KNIME and also just started looking into data mining. i have created a document where i have extracted data of a social media forum and put it in a csv file.
i want to create a worflow on knime where i I can filter a word for example 'teens' and all the data that is related to that keyword is displayed as an output. I am struggling as to where to start and how to implement this. I have searched on-line and nothing seems to be helping. is there any suggestions you can give me as to where I can start my workflow.
filtering by string can e.g. be achieved using the standard "Row Filter" node: You can apply exact matching, wildcards such as *keyword*, or even regular expressions.
for a bit of advanced techniques you could create n-grams and filter them based on the terms you are interested in, to see co-occurring words. Alternatively you can also use the term co-occurrence counter node.
