Abstract: Architecture that utilizes web search implicitly to assist users in improving writing and associated productivity. The architecture extends the authoring experience of applications of office suite applications which can draw on a web search engine to offer contextual suggestions for revision, word auto-complete, and text prediction. Web-based research and reference to users is enabled as the user writes or revises text. Suggestions are made as to how to complete a phrase or sentence using data from networks such as the Internet or intranet, to how a user how revises a word or phrase in an already-written sentence using data from the network, and to problems in writing style/writing rules. Paragraph analysis is performed to find improper language usage or errors. Prediction and revision suggestions are extracted from web search or enterprise search document summaries, and intent of the user to obtain word completion, revision assistance, and prediction suggestions is identified.

Abstract: One or more techniques and/or systems are disclosed for detecting a quick response (QR) code. An area of an image comprising a QR code is localized by combining pixel dynamic scale (DS), black-cell ratio (BR), and edge intensity sum (EIS) criteria determination to identify the QR code. A pattern for the QR code is detected, comprising determining if a position detection pattern (PDP) is located in respective grid areas of a first grid that comprises the QR code, and identifying an alignment pattern (AP), if present. To identify the AP, an AP region is estimated using the PDPs, and a center area of the AP is found by examining respective areas of a second grid comprising the estimated AP region.
