PulsExpert: An expert system for the diagnosis and control of diseases in pulse crops

This paper presents design and development of an expert system for the diagnosis and control of diseases in pulse crops (PulsExpert). PulsExpert is an operational automatic diagnostic tool that helps farmers/extension workers to identify diseases of major pulse crops viz., Chickpea, Pigeonpea, Mungbean and Urdbean (highly consumed pulse crops) and suggests the appropriate control measures. Automatic knowledge acquisition system of PulsExpert provides user-friendly interface to the domain experts for entering, storing and structuring the domain specific knowledge. The knowledge base has been designed after examining the type and structure of the knowledge from different sources like literatures, books, databases, farmers, extension workers, etc. For a particular crop, knowledge can be entered by more than one expert using an automatic knowledge acquisition system and system automatically integrates the knowledge to build a consistent knowledge base. The knowledge base of PulsExpert contains up-to-date knowledge about 19 major diseases of pulses appearing right from seedling to maturity. The system provides user-friendly interface to farmers and asks the textual as well as pictorial questions. The order of questions to be asked is decided dynamically depending upon the answers of the farmer. On the basis of answers, PulsExpert diagnosis the pulse crop diseases along with its confidence factor and suggests most appropriate control measures which are composed of cultural practices as well as chemical controls. PulsExpert was evaluated by a team of field farmers and State Agriculture Officers and it was considered good with an average rank of 2.745 by farmers and 2.075 by State Agriculture Officers with a statistic mode ranking 3 in both the cases.     

Assessing Mobile Technology Usage for Knowledge Dissemination among Farmers in Punjab

Agriculture-based precise and accurate information needs to be disseminated promptly to farmers so that better decisions such as managing farm fields, making continuous and scientific changes in their production systems and grabbing advantage of market opportunities can be made. In this paper, mobile technology is assessed for the agriculture information dissemination system. A survey has been conducted to find out potential technology, related to the use of the Internet and mobile among farmers in the state of Punjab in India, to deliver agriculture-related information to them. Results show that agricultural information system needs to be developed based on the mass communication technology such as mobile systems. It is also noted that localization and native language of farmers are the concerns to be incorporated into the systems. It has been focused that the use of soft-computing techniques in conjunction with communication networks, for inferring the decision regarding best practices for agricultural activities, is helpful in the development of these systems.     

Integrating local knowledge and biophysical modeling to assess nitrate losses from cropping systems in drinking water protection areas

Addressing the issue of agricultural pollution in water protection areas (WPA) requires assessing the impact of agricultural activities at regional scales. However, current water quality modeling studies often neglect the agronomic concept of a cropping system and interactions with soils. This paper presents a participatory assessment framework involving local experts in building a shared diagnosis of nitrate losses from cropping systems in a WPA. It includes a co-designed typology of landscape units and participatory assessment of nitrate losses with the modeling software Syst'N. Results show that characteristics of cropping systems depended on soils and that nitrate losses were highest in shallow soils. Intercrop periods were identified as critical periods for nitrate leaching, which demonstrates the importance of considering pluri-annual crop rotations rather than individual crops. The framework is generic for a modeling approach based on the involvement of local experts, who define their functional system in an agronomically sound way.

Understanding mass participatory pervasive computing systems for environmental campaigns

Participate was a 3-year collaboration between industry and academia to explore how mobile, Web and broadcast technologies could combine to deliver environmental campaigns. In a series of pilot projects, schools used mobile sensors to enhance science learning; visitors to an ecological attraction employed mobile phones to access and generate locative media; and the public played a mobile phone game that challenged their environmental behaviours. Key elements of these were carried forward into an integrated trial in which participants were assigned a series of environmental missions as part of an overarching narrative that was delivered across mobile, broadcast and Web platforms. These experiences use a three-layered structure for campaigns that draw on experts, local groups and the general public, who engage through a combination of playful characterisation and social networking.     

The sensor internet at work: Locating everyday items using mobile phones

We present a system for monitoring and locating everyday items using mobile phones. The system is based on phones which are enhanced with the capability to detect electronically tagged objects in their vicinity. It supports various functionalities: On the one hand, phones can store the context in which users leave registered items and thus help to locate them later on. On the other hand, object owners can search for their objects using the infrastructure of mobile phones carried by other users. We describe the design of our object location system and provide an algorithm which can be used to search for lost or misplaced items efficiently by selecting the most suitable sensors based on arbitrary domain knowledge. Furthermore, we demonstrate the practicability of such wide-area searching by means of user-held sensors in a series of simulations complemented by a real-world experiment.

Multimodal object oriented user interfaces in mobile affective interaction

In this paper, we investigate an object oriented (OO) architecture for multimodal emotion recognition in interactive applications through mobile phones or handheld devices. Mobile phones are different from desktop computers since mobile phones are not performing any processing involving emotion recognition whereas desktop computers can perform such processing. In fact, in our approach, mobile phones have to pass all data collected to a server and then perform emotion recognition. The object oriented architecture that we have created, combines evidence from multiple modalities of interaction, namely the mobile device’s keyboard and the mobile device’s microphone, as well as data from emotion stereotypes. Moreover, the OO method classifies them into well structured objects with their own properties and methods. The resulting emotion detection server is capable of using and handling transmitted information from different mobile sources of multimodal data during human-computer interaction. As a test bed for the affective mobile interaction we have used an educational application that is incorporated into the mobile system.

Development of a web-based survey system for evaluating affective satisfaction

The concept of affective satisfaction is used to measure subjective feelings or impressions toward a product and to provide designers with knowledge about how well users are affectively satisfied. Numerous studies of affective satisfaction toward mobile devices have been conducted in laboratory environments. However, evaluating affective satisfaction whenever a new product is designed can be expensive. Therefore, this study proposes a method to develop a web-based survey system for evaluating affective satisfaction. A case study evaluating the affective satisfaction of thirty mobile phones was conducted by more than three hundred participants. The multiple linear regression technique was applied to build the relationship models between affective satisfaction and design features of the mobile phones. The proposed method can be used for a guideline to evaluate the affective satisfaction over the internet. Moreover, designers can use this method in product families other than mobile phones.

Relevance to industry

The results of this study can be used to evaluate affective satisfaction of consumer electronic products efficiently. Moreover, designers can get feedback on their prototypes of products through analyzing the evaluation results.

Recommendation system using location-based ontology on wireless internet: An example of collective intelligence by using ‘mashup’ applications

Location-Based Service (LBS) is considered as a key component of upcoming ubiquitous environments. A recommendation system based on LBS is expected to be an important service in ubiquitous environments, and most hardware technologies such as location estimation of a user by using Global Positioning System (GPS), as well as hi-speed internet access through cell phones, are currently supported. However, in terms of software, most services are driven and supported by a LBS service provider only. Consequently, lack of participation of users may occur in mobile environments. In this study, we suggest a LBS knowledge base inference platform with ontology which considers the current location and available time of users. Our knowledge base supports user participation as collective intelligence. We mashed up Open Application Programming Interface (OpenAPI) for scalable implementation of the system. Through experiments, we show that a user can build up his/her knowledge base, and by using this information, the system recommends to other users appropriate information that matches the user’s condition and profile through inference.
