Grading essays ontologies

Ontology and Epistemology are branches of philosophy. Let us try and simplify these complex topics. It tries to pin point things around us that actually exist. It is the study of the nature of being or becoming existence and their differences and similarities.

The process of textual entailment is guided by hypotheses, which are extracted from a domain ontology. Textual entailment checks if the truth of Grading essays ontologies hypothesis follows from a given text.

We enact textual entailment to compare students answer to a model answer obtained from ontology. We validated the solution against various essays written by students in the chemistry domain.

In the current con- text of massive open online courses MOOCassessment is challenging as it aims to ensure consistency, reliability and do not favor one person against another.

In formative assessment the problem of workload and timely results is even greater, as the task is carried out more frequently while the interpretation of one human marker differs from another. While essay questions are advantageous to student learning and assessment there are obvious disadvantages for the in- structor.

Grading of essay and discussion questions is time consuming even with the help of teaching assistants. Au- tomated essay grading [21] aims at automatically assigning a grade to a students essay by means of various features.

Since the argument structure is crucial for evaluating essay quality, persuasive essays are extensively studied [22].

We argue that information technology is able to assist and support teachers in these challenges. Our research hyphotesis relies on the correlation between textual entailment [1] and answer correctness.

In a typical answer assessment scenario, we expect a correct answer to entail the reference answer. However a student may wish to skip the details already mentioned in the question.

Hence, the problem is whether the answer, along with the question, entail the reference answer. Let the question be a, student answer be sand the reference answer be r.

We propose the usage of recognizing textual entailment RTE along with shallow text features to train on the system dataset and testing it on the test dataset provided. The evaluation metrics used will be according to the Coh-Metrix system [10].

The rest of the paper is organized as follows: Section III details a running scenario on students essays in the chemical domain. Section IV discusses related work, while section V concludes the paper.

The system is structured on layers. The second layer exploits the OWLNatural service [9], to generate natural text from a selected ontology.

We organise the text generated by OWLNatural as a set of hypotheses. In the second layer, textual entailment is used to analyse the domain hypotheses on the available essays. Automatic grading includes also various readability metrics.

For this step, we use GATE tool for natural language process- ing [4], to get the number of tokens or number of sentences from text. We integrate Coh-Metrix service [11] to compute various cohesion and coherence metrics for written texts. The following four components are detailed: AI] 9 Nov Fig.

Developing the domain ontology We assume that the professor provides a corpus of relevant documents in the domain of interest. Our approach is to automatically generate a domain ontology from this corpus. For this task, we rely on Text2Onto framework for ontology learning from textual resources.Grading: Grades will be based on three factors: (1) quizzes, (2) three take-home essay exams, and (3) class participation.

There are five unannounced quizzes, each worth 10 points. There are five unannounced quizzes, each worth 10 points.
