Sentiment Analysis, Word Frequency, Design Process, and Plant Recognition
- SentiWordNet — WordNet with hints as to sentiment of particular terms, for use in sentiment analysis. (via Matt Biddulph)
- Word Frequency Lists and Dictionaries — also for text analysis. This site contains what we believe is the most accurate frequency data of English. It contains word frequency lists of the top 60,000 words (lemmas) in English, collocates lists (looking at nearby words to see word meaning and use), and n-grams (the frequency of all two and three-word sequences in the corpora).
- Crash Course in Web Design for Startups — When I was a wee pixel pusher I would overuse whatever graphic effect I had just learned. Text-shadow? Awesome, let’s put 5px 5px 5px #444. Border-radius? Knock that up to 15px. Gradients? How about from red to black? You can imagine how horrible everything looked. Now my rule of thumb in most cases is applying just enough to make it perceivable, no more. This usually means no blur on text-shadow and just a 1px offset, or only dealing with gradients moving between a very narrow color range. Almost everything in life is improved with this rule.
- Leafsnap — Columbia University, the University of Maryland and the Smithsonian Institution have pooled their expertise to create the world’s first plant identification mobile app using visual search—Leafsnap. This electronic field guide allows users to identify tree species simply by taking a photograph of the tree’s leaves. In addition to the species name, Leafsnap provides high-resolution photographs and information about the tree’s flowers, fruit, seeds and bark—giving the user a comprehensive understanding of the species. iPhone for now, Android and iPad to come.
