Chatbots are going to be the main tool for automated conversations with customers. Still, there is no consistent methodology for choosing a suitable chatbot platform for a particular business. This paper proposes a new method for chatbot platform evaluation. To describe the current state of chatbot platforms, two high-level approaches to chatbot platform design are discussed and compared. WYSIWYG platforms aim to simplicity but may lack some advanced features. All-purpose chatbot platforms require extensive technical skills and are more expensive but give their users more freedom in chatbot design. We provide an evaluation of six major chatbot solutions. The proposed method for the chatbot selection is demonstrated on two sample businesses – a large bank and a small taxi service.
There are many different types of places in any city. These places include playgrounds, dog runs, cultural heritage sites and many more. A city usually wants to provide information about location and equipment of these places. The common way is via a city website. However, nowadays a much more common source of information are mobile applications. This article deals with a development of a mobile application for the Brno‑North district of Brno city. The application is designed to inform the citizens of the city district about interesting places in their vicinity. The central element of the application is a map which shows where all the interesting places are located. The application is focused primarily on families; however, it can be useful for any citizen of the district.
Although mobile applications are commonly using user location and behavior to provide relevant content, public information panels usually lack the ability to adjust the content for a particular user or a group of users. Therefore, we focused on the development of information panels that are able, in combination with a mobile application, to collect anonymous location data about the users, identify key behavioral patterns and provide content that is relevant for the users in the panel vicinity. The key property of our solution is the anonymity of the collected information and privacy in general. The proposed algorithm consists of the data clustering and subsequent analysis. Described solution can be used in any public building or campus that the users visit regularly.
Information panels are a common part of university or administrative buildings. We can see large panels with news or social media feeds as well as small displays on conference rooms with information about their occupancy. All these panels usually present general information without any relation to a present audience. Presentation of personalised information for a particular user can be very helpful; however, for such personalisation we must take into account many aspects: identification of users in the display vicinity, sharing of the screen among multiple users etc. This paper is focused on the architecture of such system that allows presenting customised information on information panels for users within university buildings. Our solution allows detection of a user via Bluetooth beacons. The selected close display then presents information related to the user. In case there are multiple users in the display vicinity, the system evaluates their requirements and decides how to share the display.
There are numerous situations when it is utmost important to share efficiently some spatial data among a group of people. Floods can be taken as an obvious example. Many stakeholders including mayor or rescue service workers must have actual information about the conditions in the terrain. And most importantly, all of these can contribute to the information. Among these situations involving the crisis management, we dare to mention especially the inventory process. Traffic signs, road lanes, trees, lights and many other different object must be regularly maintained. Most of the organizations use some kind of geographical information system to keep the information about the maintained property. Our article is focused on development of mobile application that allows to acquire spatial data that are later used in these information systems. Thanks to real-time data synchronization between multiple devices, field workers can cooperate and share data immediately to an operating center or with the other workers. We describe the design of our mobile mapping application, comparison with other existing solutions and problems of real-time synchronization between different devices. Finally, we provide details about application usage in different municipalities.
