Oblivious Document Capture and Real-Time Retrieval
نویسندگان
چکیده
Ever since text processors became popular, users have dreamt of handling documents printed on paper as comfortably as electronic ones, with full text search typically appearing very close to the top of the wish list. This paper presents the design of a prototype system that takes a step into this direction. The user’s desktop is continuously monitored and of each detected document a high resolution snapshot is taken using a digital camera. The resulting image is processed using specially designed dewarping and OCR algorithms, making a digital and fully searchable version of the document available to the user in real-time. These steps are performed without any user interaction. This enables the system to run as a background task without disturbing the user in her work, while at the same time offering electronic access to all paper documents that have been present on the desktop during the uptime of the system.

Enhancing LambdaMART Using Oblivious Trees
Learning to rank is a machine learning technique broadly used in many areas such as document retrieval, collaborative filtering or question answering. We present experimental results which suggest that the performance of the current state-of-the-art learning to rank algorithm LambdaMART, when used for document retrieval for search engines, can be improved if standard regression trees are replac...
متن کاملImproved Skips for Faster Postings List Intersection
Information retrieval can be achieved through computerized processes by generating a list of relevant responses to a query. The document processor, matching function and query analyzer are the main components of an information retrieval system. Document retrieval system is fundamentally based on: Boolean, vector-space, probabilistic, and language models. In this paper, a new methodology for mat...

متن کاملComparing Earnings Management in Germany and the USA
This study presents empirical evidence concerning the effect of different accounting standard on earnings management. Prior studies have shown that accounting standards influence earnings management. Tighter accounting standards regime restricts management’s descretion to manipulate accruals, and at the same time, induce more costly real earnings management activities. To investigate this iss...
