Details of these techniques have been published elsewhere and summaries of particular results will be provided below. Introduction While writing is an essential part of the educational process, many instructors find it difficult to incorporate large numbers of writing assignments in their courses due to the effort required to evaluate them.

The IEA can be applied for both distance education and for training in the classroom. At a minimal level, the IEA can be used as a consistency checker, in which the teacher grades the essays and then the IEA re-grades the essays and indicates discrepancies between the two grades.

Based on evaluations of the IEA over a wide range of essay topics and levels, the IEA proves as reliable at evaluating essay quality as human graders.

Computer grading of student prose using modern concepts and software. Intelligent essay assessor software IEA uses Latent Semantic Analysis LSAwhich is both a computational model of human knowledge representation and a method for extracting semantic similarity of words and passages from text.

Thus grading and commenting on written texts is important not only as an assessment method, but also as a feedback device to help students better learn both content and the skills of thinking and writing. View more information and demonstrations hosted at Knowledge Technologies.

A huge drawback is that the tests are time-consuming and difficult to grade fairly and accurately, particularly for large classes or nationally administered exams. The LSA similarity between words and passages is measured by the cosine of their contained angle in a dimensional "semantic space".

Thus grading and criticizing written products is important not only as an assessment method, but also as a feedback device to help students better learn both content and the skills of thinking and writing. Over many diverse topics, the IEA scores agreed with human experts as accurately as expert scores agreed with each other.

This overall approach is consistent with the goals of "Writing Across the Curriculum" because it makes it easier for faculty outside of English or the humanities to introduce more writing assignments in their courses.

In each case, the essays were also graded by at least two course instructors or expert graders, for example professional readers from Educational Testing Service, or other national testing organizations.

However, the ability to convey information verbally is an important educational achievement in its own right, and one that is not sufficiently well assessed by other kinds of tests. Indexing By Latent Semantic Analysis.

A demonstration is available at: Essays can be evaluated on a secure server and scores can be returned directly either to the students or to the teachers along with the essays.

The holistic method has been tested on a large number of essays over a diverse set of topics. To verify the effectiveness of this approach for providing accurate grades, the average correlation among the three human graders was 0.

A demonstration is available at http:The computer software, called Intelligent Essay Assessor, uses mathematical analysis to measure the quality of knowledge expressed in essays. It is the only automatic method for scoring the knowledge content of essays that has been extensively tested and published in peer-reviewed journals.

The Intelligent Essay Assessor (IEA) is a set of software tools for scoring the quality of essay content.

The IEA uses Latent Semantic Analysis (LSA), which is both a computational model of human knowledge representation and a method for extracting semantic similarity of words and passages from text.

This model is then used to score student responses. Software products such as e-raterĀ® by Educational Testing Service (Burstein, Tetreault & Madnani, ) and Intelligent Essay Assessor TM. The Intelligent Essay Assessor (IEA) is a set of software tools for scoring the quality of essay content.

The IEA uses Latent Semantic Analysis (LSA), which is both a computational model of human. The Intelligent Essay Assessor software, being presented Thursday at a meeting of education researchers in San Diego, mimics the way a teacher grades essays.

The software focuses on content rather than writing ability, but ''it turns out the two are highly correlated.
