KNOWLEDGE-BASED INTERPRETATION O F SCANNED BUSINESS LETTERS

ABSTRACT Office Automation by electronic text processing has not reduced the amount of paper used for communication and storage. The present boom of FAXSystems proves this tendency. With this growing degree of ofice automation the paper-computer interface becomes increasingly important. To be useful, this interface must be able to handle documents containing text as well as graphics, and convert them into an electronic representation that not only captures content (like in current OCR readers), but also the layout and logic structure. Ure describe a system for the analysis of business letters which is able to extract the key elements of a letter like its sender, the date, etc. The letter can thus for instance be stored in electronic archival systems, edited by structure editors, or forwarded via electronic mail services. This system was implemented on a Symbolics Lisp machine for the high level part of the analysis and on a VAX for the low and medium level processing stages. Some practical results are presented and discussed. Apart from this application our system is a useful testbed t o implement and test sophisticated control structures and model representations for image understanding

Applications used in workgroup information systems. Group collaboration in business

Individuals in a business usually do not work entirely alone, but instead in teams, committees, departments, and other types of workgroups. To collaborate on common tasks, workgroup members can have meetings, talk on the telephone, send faxes, and distribute memos. Group members can also use workgroup information systems to help them collaborate. This type of system is also called a group support system because it supports the work of people in a group. This article looks at applications used in workgroup information systems, and shows how these applications affect group collaboration in businesses. First, we explain how workgroup information systems encourage group collaboration. Then we examine the characteristics of group collaboration and describe common workgroup applications and the software used for these applications, and finally we discuss about office automation and the virtual work environment.group collaboration, workgroups, office automation, virtual environment

RGB-D datasets using microsoft kinect or similar sensors: a survey

RGB-D data has turned out to be a very useful representation of an indoor scene for solving fundamental computer vision problems. It takes the advantages of the color image that provides appearance information of an object and also the depth image that is immune to the variations in color, illumination, rotation angle and scale. With the invention of the low-cost Microsoft Kinect sensor, which was initially used for gaming and later became a popular device for computer vision, high quality RGB-D data can be acquired easily. In recent years, more and more RGB-D image/video datasets dedicated to various applications have become available, which are of great importance to benchmark the state-of-the-art. In this paper, we systematically survey popular RGB-D datasets for different applications including object recognition, scene classification, hand gesture recognition, 3D-simultaneous localization and mapping, and pose estimation. We provide the insights into the characteristics of each important dataset, and compare the popularity and the difficulty of those datasets. Overall, the main goal of this survey is to give a comprehensive description about the available RGB-D datasets and thus to guide researchers in the selection of suitable datasets for evaluating their algorithms

Technology assessment of advanced automation for space missions

Six general classes of technology requirements derived during the mission definition phase of the study were identified as having maximum importance and urgency, including autonomous world model based information systems, learning and hypothesis formation, natural language and other man-machine communication, space manufacturing, teleoperators and robot systems, and computer science and technology

Importance and applications of robotic and autonomous systems (RAS) in railway maintenance sector: a review

Maintenance, which is critical for safe, reliable, quality, and cost-effective service, plays a dominant role in the railway industry. Therefore, this paper examines the importance and applications of Robotic and Autonomous Systems (RAS) in railway maintenance. More than 70 research publications, which are either in practice or under investigation describing RAS developments in the railway maintenance, are analysed. It has been found that the majority of RAS developed are for rolling-stock maintenance, followed by railway track maintenance. Further, it has been found that there is growing interest and demand for robotics and autonomous systems in the railway maintenance sector, which is largely due to the increased competition, rapid expansion and ever-increasing expense

Advancing automation and robotics technology for the Space Station and for the US economy. Volume 1: Executive overview

In response to Public Law 98-371, dated July 18, 1984, the NASA Advanced Technology Advisory Committee has studied automation and robotics for use in the Space Station. The Executive Overview, Volume 1 presents the major findings of the study and recommends to NASA principles for advancing automation and robotics technologies for the benefit of the Space Station and of the U.S. economy in general. As a result of its study, the Advanced Technology Advisory Committee believes that a key element of technology for the Space Station is extensive use of advanced general-purpose automation and robotics. These systems could provide the United States with important new methods of generating and exploiting space knowledge in commercial enterprises and thereby help preserve U.S. leadership in space

Comparison of the Information Technology Development in Slovakia and Hungary

Nowadays the role of information is increasingly important, so every company has to provide the efficient procurement, processing, storage and visualization of this special resource in hope to stay competitive. More and more enterprises introduce Enterprise Resource Planning System to be able to perform the listed functions. The article illustrates the usage of these systems in Hungary and Slovakia, as well as tests the following presumption: the level of Information Technology (IT) development is lower in Hungary than our northern neighbor

Advancing automation and robotics technology for the space station and for the US economy: Submitted to the United States Congress October 1, 1987

In April 1985, as required by Public Law 98-371, the NASA Advanced Technology Advisory Committee (ATAC) reported to Congress the results of its studies on advanced automation and robotics technology for use on the space station. This material was documented in the initial report (NASA Technical Memorandum 87566). A further requirement of the Law was that ATAC follow NASA's progress in this area and report to Congress semiannually. This report is the fifth in a series of progress updates and covers the period between 16 May 1987 and 30 September 1987. NASA has accepted the basic recommendations of ATAC for its space station efforts. ATAC and NASA agree that the mandate of Congress is that an advanced automation and robotics technology be built to support an evolutionary space station program and serve as a highly visible stimulator affecting the long-term U.S. economy
