Calliope is a different type of text mining tools, being more of a text synthesizer that can rapidly read massive amounts of unstructured text. Calliope cannot be used for web data analytics since it has no ability to crawl the internet pages. Also, it is currently usable only on Windows.
Still Takes Human Intellect
The Calliope process requires a certain amount of human interaction to focus the analytics following the intial analysis step. If the initial analytics fails to product a topic list based on applied algorithms, users must create one of their own. This is done using a wizard which allows the creation of focused terms and high-value words, if the analysis results doesn’t produce one.
Calliope calculates the relationship of words that are “thematically homogeneous.” These analogous terms are called “co-words” which are related words found within the body of analyzed text. Repeated processing on different text collections refines the results and categorizes them as “emerging” (positive value of significance) or “declining” if they are not important over time.
