Grading Multiple Choice Questions Based On Similarity Measure (Published)
Recent findings show the poor performances of students in Multiple Choice Questions (MCQ) examinations. This could be attributed to the administration of questions on application of knowledge rather than on fundamental of knowledge. Candidates doing these examinations at times choose options that are close to the actual answer but get zero (0) as the reward. The objective of developing a system that rewards a candidate based on the approximation of an option chosen not on the exactness of the option to the answer was therefore formulated in this study. 500 MCQs with their model answers, students’ answers and scores obtained from two universities in Nigeria were collected. Jaro similarity measure was used to compute the degree of similarity between the model answers and the student answers. Results of the experiment show an average deviation of 13.3 marks. The adoption of this method of grading would be very beneficial in evaluating learners on e-learning platforms. The result is encouraging but could be improved upon with semantic similarity measure hybridized with string similarity.

Robinson’s diagram as a tool for dealing with Skolem’s criticism of formal language (Published)
In this paper, I wish to present Robinson’s diagram as an attempt to overcome the problem of formal language, which was indicated in 1922 by Skölem as the “relativity of set-theoretical notions”. Robinson’s diagram is a symbolic representation of information. The diagram of a mathematical structure M is the set of all elementary sentences of one of the forms j or ¬j which hold in M, where j = R(a1,….,an) for any R, a1,….,an which denotes relations of individuals a1,….,an, in M. The diagram is syntactic and semantic at the same time. Using the diagram with the philosophical position that links semantics and syntactic it is possible to find the unique model that is described by a set of axioms.
