![]() ![]() Generally, though, the app does a decent job of picking out three to four key points of the page it's summarizing, and it does so remarkably fast. Also, if the content of a site is under 500 characters, Summly won't provide a summary - because the site content is already pretty concise at that point. It will sometimes include dates or minor numerical figures as bullet points, or an expository sentence in the opening paragraph of an article that doesn't actually contain any rich information. That was then tested against other algorithms. From this, they derived a recall/precision score. D'Aloisio says that to get this number, they took a corpus of past documents and articles and compared the quality of human summaries to Summly's output. In tests performed independently by researchers at MIT, the summaries from D'Aloisio's patent-pending technologies performed up to 30 percent better than other existing algorithms. It's currently optimized in 12 different languages (primarily Latin-based), but will soon expand to Chinese now that Summly has the backing of Hong Kong billionaire investor Li Ka Shing. In fact, because Summly is language-independent, language isn't a barrier to its functionality. The app doesn't do quite as well with narrative text written in the third person, but D'Aloisio says that there are no areas that are seriously troublesome to his algorithm. Tech articles and news articles tend to marry well with Summly's algorithm, as does the consistently organized content from the New York Times and the BBC. This lets the algorithm learn what's important - and where to find that important information - more easily. However, you can also type in a URL if you have a specific text-heavy web page you'd like summarized.ĭ'Aloisio says that Summly works best with well-formulated articles that conform to a consistent structure. You'll also notice that typical results like Wikipedia articles and dictionary definitions don't show up in the listing the search function generally appears to be limited to actual news articles relating to the subject you type in. When you search for a topic using the app, it compiles results from different search engines, so you'll notice it doesn't deliver the same results as a Google search, or even a Bing search. ![]()
