A task completion engine to enhance search session support for air traffic work tasks

Providing support for users during their search sessions has been hailed as a major challenge in interactive information retrieval (IIR). Providing such support requires considering the context of the search and facilitating the work task at hand. In this paper, we consider the work tasks associated with air traffic analysts, who perform numerous searches using a multifaceted search interface in order to acquire business intelligence regarding particular events and situations. In particular, we develop a novel task completion engine and seamlessly incorporated it within a current air traffic search system to facilitate the comparison of information objects found. In a study with 24 participants, we found that they completed the complex work task faster using the comparison feature, but for simple work tasks, participants were slower. However, participants reported (statistically) significantly higher satisfaction and had (statistically) significantly higher accuracy using the search system equipped with task completion engine. These findings help to steer systems to provide a better support to users in their search process. © Springer International Publishing AG 2017

An Intelligent Marketspace Mobile Application for Marketing Organic Products

Sustainable food security (Sfs) desires not only that people always have passage to ample and nutritious food, but also that this food be formed with minimum environmental impact. This research is aimed at developing a mobile application for marketing organic farm products with the functionality of automated geo-location services, preferred goods delivery services, easy access to different organic farm produce. The mobile user platform consists of the Presentation, Business, Data and Data storage which is a slight variation of the Model-View-Controller architecture. It also takes into deep awareness the configuration, security and communications aspect as these are the underlying factors for the robustness of mobile application. The Presentation Tier consists of the user interface and the logic used to navigate around the user interface meaningfully. It modifies and shows information into a human distinct pattern. The Business Logic tier is essentially efficient for information transfer between the user interface and the database of the project. The last layer of the three-tiered architecture is the Data Access tier, which is made up of the Database servers. The application was implemented in Java, SQLite (local) and PHP for the backend server and Amazon Web Services for cloud infrastructure. Farmers were engaged in cursory testing. Users find the application concept very interesting

Ontology-Based Model for Food Transformation Processes - Application to Winemaking

International audienceThis paper describes an ontology for modeling any food processingchain. It is intended for data and knowledge integration andsharing. The proposed ontology (Onto-FP) is built based on four mainconcepts: Product, Operation, Attribute and Observation. This ontologyis able to represent food product transformations as well as temporal sequenceof food processes. The Onto-FP can be easy integrated to otherdomains due to its consistencies with DOLCE ontology. We detail anapplication in the domain of winemaking and prove that it can be easyqueried to answer questions related to data classication, food processitineraries and incomplete data identication
