Modelling Grammaticality-grading in Natural Language Systems Using a Vector Space Approach
Journal Title: Journal of Advances in Mathematics and Computer Science - Year 2017, Vol 23, Issue 3
Abstract
There exist several natural language processing systems that focus on checking the grammaticality (grammatical correctness or incorrectness) of natural language texts. Studies however showed that most existing systems do not assign specific scores to the grammaticality of the analysed text. Such scores would for instance prove very useful to second language learners and tutors, for judging the progress made in the learning process and assigning performance scores respectively. The current study was embarked upon to address this problem. A grammaticality grading model which comprised of 6 equations was developed using a vector space approach. The model was implemented in a natural language processing system. Correlation analysis showed that the grading (in %) performed using the developed model correlated at a coefficient of determination (R2) value of 0.9985 with the percentage of grammatical sentences in evaluated texts. The developed model is therefore deemed suitable for grammaticality grading in natural language texts. The developed model would readily find use in computer aided language learning and automated essay scoring.

Structure of Some Pregroups and Length Functions
The concept of Pregroups was introduced by Stallings in 1971. Subsequently the concept of Pregroups was developed by many other researchers. Stallings originally defined a set with a binary operation satisfying five axi...
Some Commutativity Theorems in Prime Rings with Involution and Derivations
Let R be a ring with involution ′∗′ . An additive map x 7→ x ∗ of R into itself is called an involution if (i) (xy) ∗ = y ∗ x ∗ and (ii) (x∗)∗ = x holds for all x; y ∈ R. An additive mapping δ : R → R is called a derivat...
