Short Text Mining for Classifying Educational Objectives and Outcomes

Abstract

Most of the international accreditation bodies in engineering education (e.g., ABET) and outcome-based educational systems have based their assessments on learning outcomes and program educational objectives. However, mapping program educational objectives (PEOs) to student outcomes (SOs) is a challenging and time-consuming task, especially for a new program which is applying for ABET-EAC (American Board for Engineering and Technology the American Board for Engineering and Technology-Engineering Accreditation Commission) accreditation. In addition, ABET needs to automatically ensure that the mapping (classification) is reasonable and correct. The classification also plays a vital role in the assessment of students' learning. Since the PEOs are expressed as short text, they do not contain enough semantic meaning and information, and consequently they suffer from high sparseness, multidimensionality and the curse of dimensionality. In this work, a novel associative short text classification technique is proposed to map PEOs to SOs. The datasets are extracted from 152 selfstudy reports (SSRs) that were produced in operational settings in an engineering program accredited by ABET-EAC. The datasets are processed and transformed into a representational form appropriate for association rule mining. The extracted rules are utilized as delegate classifiers to map PEOs to SOs. The proposed associative classification of the mapping of PEOs to SOs has shown promising results, which can simplify the classification of short text and avoid many problems caused by enriching short text based on external resources that are not related or relevant to the dataset.

Semantic Querying of Knowledge Rich Legal Digital Libraries Using Prism1

“…in terms of techniques and applications. Among the search techniques currently in use, some form of keyword search [17] or text mining based association search [1] are prevalent. In recent research, however, an emerging trend of searching digital libraries using knowledge graphs (KG) is gaining popularity [8] with the goal to improve semantic matching [9].…”
