Automatic Identification of Terms for the Generation of Students’ Concept Maps
نویسندگان
چکیده
Willow [1], an adaptive multilingual free-text Computer-Assisted Assessment system, automatically evaluates students’ free-text answers given a set of correct ones. This paper presents an extension of the system in order to generate the students’ concept maps while they are being assessed. To that aim, a new module for the automatic identification of the terms of a particular knowledge field has been created. It identifies and keeps track of the terms that are being used in the students’ answers, and calculates a confidence score of the student's knowledge about each term. An empyrical evaluation using the students' real answers show that it is robust enough to generate a good set of terms from a very small set of answers.

Search-based optimization methods have been used for software engineering activities such as software testing. In the field of software testing, search-based test data generation refers to application of meta-heuristic optimization methods to generate test data that cover the code space of a program. Automatic test data generation that can cover all the paths of software is known as a major cha...
متن کاملBanach module valued separating maps and automatic continuity
For two algebras $A$ and $B$, a linear map $T:A longrightarrow B$ is called separating, if $xcdot y=0$ implies $Txcdot Ty=0$ for all $x,yin A$. The general form and the automatic continuity of separating maps between various Banach algebras have been studied extensively. In this paper, we first extend the notion of separating map for module case and then we give a description of a linear se...

For Fr$acute{mathbf{text{e}}}$chet algebras $(A, (p_n))$ and $(B, (q_n))$, a linear map $T:Arightarrow B$ is textit{almost multiplicative} with respect to $(p_n)$ and $(q_n)$, if there exists $varepsilongeq 0$ such that $q_n(Tab - Ta Tb)leq varepsilon p_n(a) p_n(b),$ for all $n in mathbb{N}$, $a, b in A$, and it is called textit{weakly almost multiplicative} with respect to $(p_n)$ and $(q_n)$...
