Diagram Interpretation and e-Learning Systems
نویسندگان
چکیده
We describe a system capable of grading free-form diagrammatic answers. Our matches meaningful parts of a diagram with equivalents in a model solution. This is complicated by errors, omissions, and superfluous items in the student answer. The result of matching is used to calculate the grade and generate appropriate feedback; it performs at least as well as a human marker on a variety of diagram types. We describe tools that allow the easy creation of questions, marking schemes, and diagram editors suitable for embedding in a VLE quiz engine.

Mothers' Interpretation of E-learning during COVID-19 Pandemic
The global spread of COVID-19 has caused disruptions in many aspects of our lives. Education systems worldwide have changed dramatically. Numerous countries have encouraged schools to shift to e-learning and, as a result, parental involvement in their children’s education has changed. This study focused on mothers’ involvement in children’s education during the COVID-19 pandemic and probed thei...
متن کاملConstrained Seismic Sequence Stratigraphy of Asmari - Kajhdumi interval with well-log Data
Sequence stratigraphy is a key step in interpretation of the seismic reflection data. It was originally developed by seismic specialists, and then the usage of high-resolution well logs and core data was taken into consideration in its implementation. The current paper aims in performing sequence stratigraphy using three-dimensional seismic data, well logs (gamma ray, sonic, porosity, density, ...
متن کاملThe Prediction of Forming Limit Diagram of Low Carbon Steel Sheets Using Adaptive Fuzzy Inference System Identifier
The paper deals with devising the combination of fuzzy inference systems (FIS) and neural networks called the adaptive network fuzzy inference system (ANFIS) to determine the forming limit diagram (FLD). In this paper, FLDs are determined experimentally for two grades of low carbon steel sheets using out-of-plane (dome) formability test. The effect of different parameters such as work hardening...
متن کاملMapping Sequence diagram in Fuzzy UML to Fuzzy Petri Net
This ability in fuzzy UML, practically leaves the customers and market’s need without response in this important and vital area. Here, the available sequence diagrams in fuzzy UML will map into fuzzy Petri net. However, the formal models ability will be added to the Semi-formal fuzzy UML. This formalization will add the automatic processing ability to the Semi-formal fuzzy UML. Further more, t...
متن کاملCLARET: A new Relational Learning Algorithm for Interpretation in Spatial Domains
A new learning algorithm: Consolidated Learning Algorithm based on Relational Evidence Theory (CLARET) is presented, which integrates a machine learning methods with graph matching techniques. A systematic approach to nding interpretations is demonstrated for an on-line, hand drawn, schematic diagram and symbols recognition system. The approach uses an adaptive representational bias and search ...
