OpeNER - Opinion targets (London)

This word cloud shows opinion target words from reviews of accommodations in London. Bigger words were identified more often by sentiment analyzers. Color represents the aggregated sentiment towards the target words (more green is more positive, more red is more negative and a yellow color is neutral). For example, both "hotel" and "room" have been mentioned a lot, but the overall sentiment towards "hotel" is more positive than the one towards "room".

Compared to a word cloud built with the same technique for the city of Amsterdam (see it here), this is more shallow and yellow, indicating a more neutral sentiment for London's opinion target words.

Data is obtained from the Tour-Pedia APIs, that in turn get their input from the sentiment analysis pipeline of the OpeNER project.

The implementation makes use of d3.layout.cloud by Jason Davies.
