The realization of office automation is also the need of the development of colleges and universities. The use of office automation to deal with a large number of daily affairs can improve the efficiency of school management. Based on the association rules, this paper calls the functions of various types of development to realize some functions of secondary development of editing and editing automation. Input efficiency will be improved by completing wizard-style input for a variety of complex documents. Automation technology is used to solve the secondary development of Office documents, which better and fully reflects the convenience brought by software openness. The application and development prospects of Office secondary development are embarrassing. As more and more users have been learning about secondary development, a new era of “paperless office” will emerge, and enterprises and institutions will become the biggest beneficiaries.

Office automation systems generally process data in XML and other formats when storing and exchanging information, which can make the computer more convenient for automatic processing to improve work efficiency. However, such data files are not easy for the average person to read. In everyday applications, this approach is not applicable on a large scale and requires editing and drawing natural language text reports based on formatted data. Most of this work is completed manually by the user, which is repeated in the work, resulting in no significant improvement in office efficiency. Therefore, in order to improve the real-time efficiency of work, people need to conduct in-depth research on the conversion mechanism from formatted data to natural language text. This system can carry out automatic data processing according to the characteristics of official document report of the office system, so as to reduce the burden of users.

This paper attempts to provide a new perspective for efficient text extraction techniques by including the layout information of the document images along with the text. The study proposes a novel approach of segmenting the image into smaller images based on its meta-data knowledge and then applying functions for recognition of text from the smaller images. Due to a lack of layout information of the text, poor results are generated during text searching by office automation tools. With this restriction usage of the text for various environments becomes limited and usage of extracted text may not be done effectively. The study proposes a technique to understand the structural and functional layout of the document image and using this knowledge to develop a better model. To verify the point of view, additional intelligence is attached to the data, making it capable to be used in varied environments. With this added quality, the new proposed system can extract and identify text or group of text into different entities within the document which the previous systems could not achieve. The proposal can be beneficial particularly for the development of various document processing tools.

With an increasing number of the student body at Telkom University, office automation is one of many possible solutions to provide better and personalized service to students. This automation also includes library services, covering self loan, self-return, and self-pickup, which commonly use RFID (Radio Frequency Identification). The problem arises in RFID-based self-service system for library automation, which is how to ensure that the ID card of the patron truly belongs to the person using the service. This problem follows the self-loan service since the ID card of the patron is used only when borrowing the collection. Another problem is how to ensure that the borrowed collection is the actual collection registered in the LMS (Library Management System). This research proposes a business process of a self loan system design that minimizes fraudulent practice in borrowing collections by merging image capture of the patron and the borrowed collection where the librarian is not necessarily present for circulation.

UID/CEC/04516/2019 The widespread use of IoTs, as cheap and immersive technology, is enabling a wide range of daily life systems where Humans play a central role. It is commonly accepted that Humans sometimes present non-reliable behaviour. On the other hand, Gamification is becoming a common technique in system development to integrate business logic and induce Humans to accomplish certain goals and enforce systems reliability. Due to human nature, the evolution of game logic becomes an essential aspect of such systems to keep users engaged and participative. In this paper, we illustrate and discuss evolution in the particular scenario of a running Office Automation System in our open space. Here, the Human plays different roles such as an actuator, source of system input, a controller (decision maker), or simply environment (Human-in-the-loop). The mentioned system is the result of partially retrofitting a room of a forty years old building. It runs with a dynamic context scenario (that motivates different setups) and is formed by a heterogeneous set of IoTs. Those types of equipment are integrated to mainly accomplish two, sometimes conflicting, main goals: energy efficiency and Human comfort. As we will describe next, given the complexity of our system, various system's requirements need to be fulfilled at the same time. Those will dynamically change during runtime to contribute to both efficiency and participants' engagement. Not only the game requirements of the system evolve, but also the participants' behaviour change. We have consulted the open space's occupants on their daily routines and their preferences towards Gamification and gamified systems, particularly considering their social settings. They were also consulted on their views towards achieving energy efficiency in the open space. The results of this assessment are presented in this paper. The major suggestions were integrated into the current design of the system. We considered those that could contribute to the system's efficiency and reliability according to the system's goals. Besides, we also considered those that led to the use of several game techniques for motivating and improving the Humans' participation. authorsversion published

With the continuous development of information technology, most enterprises have realized office automation and the business process runs through the whole life of enterprise activities. The importance of business processes to modern enterprises is self-evident. With the development of business processes, business process reengineering as an advanced management theory has become an important issue in the production and management of modern enterprises. However, most companies do not have a efficiency analysis system to evaluate existing business processes, so they cannot effectively reengineer business processes. In addition, the cost of process reengineering is very high, and blind transformation will result in a waste of manpower, material resources and financial resources. So, although the business process reengineering theory has been advanced, the implementation success rate is very low. In this paper analyzes and studies the composition and characteristics of Primeton platform. Based on this, a business process efficiency analysis system is constructed, which can dynamically and accurately display the efficiency of the department and activity nodes. The system provides a reliable data reference for business process reengineering and can effectively guide companies to effectively evaluate existing business processes.

Home or Office Automation may be described as a system to provide ease of operation of connected devices or appliances. Most commercial environments, during active hours, consume large amounts of energy resources; this could be optimized to the minimum by smartly monitoring and managing the resources. IoT (Internet of Things) enables this to be a possible solution at reasonable cost factors. However, it is important to note that in commercial environments, security is a key factor; corporations cannot depend on opening up their networks to the outside world in order to avail the services offered by currently available smart-devices. Localizing and privatizing the entire automation and control system would be desirable for such domains. The work presented in this paper proposes a solution for such applications which is crucial for the development of Smart Cities as a whole along with Smart Homes. One of the simplest tasks is to switch a light source, HVAC systems or any other electrical equipment on or off, by being physically present in the premises, remotely or automatically based on time or a sensor's reading. Furthermore, the intensity of the light source, the temperature of the HVAC systems and such parameters could also be varied. Development of technology in the field has enabled the production of cheap and small-sized computers like Raspberry Pi which are also known as Single Board Computers (SBC). The prototype designed is equipped with a secure local MQTT link for communication between the control and automation system and the Edge Devices. Additionally, it is equipped with a speech recognition system to give the users a much more intuitive and natural mean to communicate with and control the connected devices.

Recently, cyber security becomes a serious problem for not only OA (Office Automation) systems but also PA (Process Automation) and FA (Factory Automation) systems. Even the controllers, which are not connected to Internet directly, have been attacked with malwares, such as Stuxnet and Quantum. When control system fails, it may lead to serious accidents such as explosion or leakage of poisonous and deleterious substances. For process control, cyber-attack is one of the causes to threaten safety. The authors of this paper had proposed zone division of process control networks to ensure cyber security and safety. To apply the method, it is necessary to build CE (Cause Effect) matrices which express the qualitative information of the plant and controllers. It is very troublesome for large-scale plants. CAD (Computer Aided Design) tool for zone dividing is proposed in this paper. CE matrices are generated by using DAE (Differential and Algebraic Equation) registered in equipment modules of plant CAD such as ASPEN or Pro II. The candidates of zone division of process control networks, which can assure the safety against concealment and remote operation by cyber attackers, can be proposed.

The modern electronics era has improved the quality of life in many ways, from residential lighting to indoor living environments to entertainment choices. As gadgets and systems remain powered up and ever ready to meet human demands, a significant portion on their up-time is spent in stand-by or low-power mode — if one is available. Unless these gadgets and systems are capable of low-power mode and controlled by a centralized control unit or individually programmed; power savings cannot be achieved. A retro-fit after-market automation scheme is needed to achieve smart power saving capabilities in a traditional (non-automated) household with multiple gadgets and systems with differing functionalities and capabilities from various manufactures. This paper describes a system architecture for retro-fitting after-market automation using a smartphone as the unifying or controlling master device.

The replica consistency detection of text images is of great significance in office automation. For example, it can be applied to detect the consistency of the printed documents of commercial contracts and the original electronic documents. In this paper, we propose a method for replica consistency detection of text images based on multi-feature assessment. Firstly, we make a photocopy of the printed document, then apply our method to detect the consistency between the photocopied text images and the original text images. Rather than recognizing each character, we only focus on the measurements of the likeness of these two text images, and no OCR techniques are required. The experiment results indicate that the method has high accuracy. Although the Chinese characters are the main research objects, the experiment results show that the method also can be used for detecting the consistency of Latin letters and Arabic numerals.
