Crop production problems are common in Sri Lanka which severely effect rural farmers, agriculture sector and the country's economy as a whole. A deeper analysis revealed that root cause was farmers other stakeholders domain not receiving right information at time format. Inspired by rapid growth of mobile phone usage among mobile-based solution is sought to overcome this gap. Farmers needed published (quasi static) about crops, pests, diseases, land preparation, growing harvesting methods...
With the continuous advancement of methods, tools, and techniques in ontology development, ontologies have emerged various fields such as machine learning, robotics, biomedical informatics, agricultural crowdsourcing, database management, Internet Things. Nevertheless, nonexistence a universally agreed methodology for specifying evaluating quality an hinders success ontology-based systems each component is required overall system turn impacts usability use. Moreover, number anomalies...
Achieving quality in use (i.e., the higher-level objectives) is now widely accepted for building a usable system and software product. However, ontology engineering discipline which theories are not yet well developed adapted thus, still does have an agreed methodology standards evaluation. As result, ontology-driven may consist of badly engineered that usable. This will turn cause adverse effect on corresponding system. It necessary to alleviate this problem by formulating evaluation...
In creating a usable Information System (IS), the quality of information is crucial for making right decisions. Although, many Quality (IQ) features have been identified in broader context, only certain IQ would become applicable each domain from usability perspective. This study focuses on theoretical analysis to identify which be significant produce agricultural system with respect developing countries. Accuracy, Credibility, Context-specific, Completeness and Timeliness are as essential...
People working in the agriculture domain Sri Lanka are affected by not being able to get vital information required support their related activities a timely manner. Some of can be found government websites, department leaflets, newspapers, etc. The is hard find from these knowledge sources due its unstructured, incomplete, varied formats, and lack targeted delivery methods. Thus finding right within context which manner challenge. relevant needs provided only structured complete way, but...
This study describes the mobile-based user needs-driven knowledge management system that supports decision making process by considering needs and preferences. Agriculture is one of domains, in which, users seek specific information relevant to their rather than searching accessing general from Web, books, magazines or other sources. Thus, conceptualized solution was created applying participatory sensing, natural language processing ontology theories techniques a novel way order satisfy...
Potato is the most popular root crop and plays a crucial role in human nutrition worldwide. However, farmers Sri Lanka face many challenges throughout at different stages of potato production. This study intends to provide context-specific actionable information using Packages Practice (PoP) model through an ICT-based mobile platform. To investigate farmers’ challenges, field survey was conducted major growing Districts Lanka. Primary data were obtained pre-tested structured questionnaire,...

Cinnamon (Cinnamomum zeylanicum Blume) is indigenous to Sri Lanka which holds a virtual monopoly of cinnamon in the world accounting for around 90% global trade. Because its industrial applications and medicinal properties, there growing demand true world. Major drawbacks industry are low productivity quality, poor value addition, lack market information, smallholdings, accessibility, inadequate unsatisfactory extension services. This study identified stakeholders services Lankan proposed...
Ontology is a machine interpretable way of representing knowledge in precise and complete favorable to solve many problems the field engineering. Different areas evolve with time applications which use ontologies should be updated new accordingly. It more effective combine existing application rather than designing ontology from scratch. When combining ontologies, keeping original usability initial heterogeneity components are main obstacles. As there no universal standard for naming...
