Development of a Web-Based Application for the Automatic Creation of Concept Maps

Abstract

Concept maps are two-dimensional visual tools providing the definition of the relationships between the concepts in a certain subject area. Although various studies indicate that the graphical display of information has a positive contribution to the process of learning, the creation of concept maps in contents especially with a high text density brings some difficulties with it. It is observed that since studies are conducted on the automatic creation of concept maps for the purpose of overcoming these difficulties, but the algorithms used in these kinds of studies are generally developed according to the language structure, the products introduced do not adjust to the language structure of Turkish. From this viewpoint, a web-based application was developed for the creation of concept maps for Turkish texts by using the term frequency and inverse document frequency algorithms and the application developed was published at www.kavramharitasiolustur.com. The concept maps created by the application can be downloaded in a format that can be used directly in web-based learning environments.

Educational Data Mining Studies in Turkey: A Systematic Review

“…Therefore, it is recommended that qualitative data should be used in data mining studies and that text mining methods should be employed in the process of preprocessing data. For example, the web-based application developed by Aydogdu and Guyer (2018) for the automatic generation of concept maps can be used as a tool in the preprocessing of textual data since it performs sorting according to the weight value of terms in a document set.…”
