Knowledge maps in agriculture and rural development

Abstract

rapid changes in the external environment require the decision-makers to select new approaches and methods of decision-making (Svoboda 2008). information and knowledge systems based on knowledge approach and or/MS methods have an important role in this process. Quality decision support systems and information and communication technologies and the quality of the provided information and knowledge for the decisionmakers are an important source of competitiveness (Šilerová, Kučírková 2008). This quality is based on the user's satisfaction with these systems (Beránková et al. 2008) and their elements as mathematical models. in connection with these facts and with wide-spread theory of knowledge mapping, more and more questions dealing with their practical use arise.Do we need to formalize knowledge? Do we need to formalize its using a knowledge map? What are we to do with a (mathematical) model to consider it as a knowledge map? is the approach of the linear programming model construction (creation) process an analogue to the process of the knowledge map creation? is there any relevant application of this process in agriculture and rural development? Some answers to these questions will issue from the following text. And finally: can we read a solution from a model in the same way as knowledge from a map? Knowledge maps in agriculture and rural developmentZnalostní mapy v zemědělství a rozvoji venkova H. Brožová, T. Šubrt, J. Bartoška Department of Engineering Systems, Faculty of Economics and Management, Czech University of Life Sciences Prague, Czech RepublicAbstract: The possibility of knowledge maps use in the decision-making process in agriculture and rural development is discussed in this paper. Each knowledge map presents a visualization of knowledge using different tools, where a mathematical model can be applied as one of them. The hierarchical structure of a knowledge map conforms to the general structure of a mathematical model. The mathematical model, when successfully solved and correctly read, is a knowledge map in itself. The parallels exist also between the creation process of a mathematical model and of a knowledge map. in general, every phase of a system approach can lead to a special knowledge map. The following paper explains this process and demonstrates it on the farm production structure optimisation problem solved by using a linear programming model. Key words: knowledge formalisation, system approach, decision-making, map creation process, model creation process Abstrakt: znalostní mapy mohou být významným nástrojem při řešení problémů zemědělství a venkova. Každá znalostní mapa vizualizuje znalost pomocí různých nástrojů. Speciálním typem této vizualizace či formalizace může být matematický model, protože hierarchická struktura znalostní mapy odpovídá obecné struktuře matematického modelu. Správně aplikovaný úspěšně řešený matematický model je tedy znalostní mapou. Existuje také paralela mezi postupem tvorby znalostní mapy a matematického modelu. Proces aplikace znalostních map ve formě ma...

Construction of Remote Sensing Indices Knowledge Graph (RSIKG) Based on Semantic Hierarchical Graph

“…They consider formulas as a special case of KG [38], because formulas satisfy the definition of KGs that represent the relationships and attributes of modeling systems [39]. Therefore, building KGs using formulas [40] could be a manner of semi-automatically developing and manipulating graphs, with mathematical semantics used to identify concepts within the graph [41].…”

Constructing Crop Portraits Based on Graph Databases Is Essential to Agricultural Data Mining

“…Lange et al [10] suggested a multiontology-based foods-for-health knowledge system. Brožová et al [11] studied the optimization of agricultural production structure using knowledge graphs. Zheng et al [12] proposed an ontology-based system for agricultural knowledge management.…”

Modified Ishikawa Diagram as a Tool for Knowledge-Mapping of Agronomic Practices

“…Znalostí mapy jsou děleny na tři základní typy (Gordon, 2000): myšlenkové mapy, koncepční mapy a kognitivní mapy. O využití znalostního mapování v agronomii se zmiňuje i zdroj (Brožová et al, 2008).…”
