Abstract: A method for processing micro-blogs includes, for each of a set of hashtags extracted from a collection of micro-blogs, decomposing the hashtag to generate a sequence of words and natural language processing the decomposed hashtag with rules configured for identifying syntactic dependencies and targets, such as proper names, in the dependencies. Opinion detection rules are applied to the detected dependencies which are configured for extracting opinion information from decomposed hashtags, such as a polarity based on presence of a polar term in a dependency. At least some of the hashtags in the set of hashtags are stored in a hashtag lexicon, the stored hashtags being associated with the extracted opinion information. A computer processor may perform the decomposing, natural language processing, applying opinion detection rules, and storing of the hashtags.

Abstract: A dual screen electronic reader and method for navigating a document are disclosed. The electronic reader includes two display screens which can be angled to each other, like an open book, for viewing by a person reading the document. The electronic reader includes a tilt detection system for detecting tilting of the electronic reader indicative that the reader has completed reading the page on the first screen and has pivoted the electronic reader to view the opposite screen. This causes the electronic reader to load a fresh page on the first screen, optionally after a short time delay, which allows for counter-rotational tilting to be taken into consideration.
