This research develops three text analytic techniques to improve survey questionnaires. The first is open-ended response mining. Narrative responses on a survey are mined for themes then used to develop new questions. Closed-ended responses identify subgroups who agree/disagree with the question. Then open-ended responses examined for systematic differences which suggest new constructs that dis...
abstract the present study was an attempt to investigate the effect of critical thinking on writing ability of 60 iranian intermediate efl learners studying at chenar language institute in khuzestan, iran. to this end, the participants of the study were selected based on their performance in an pet test, a cornell critical thinking test form x and a pre-test of writing. the participants un...
in this research,the authors conducted a study comparing two groups of male and female english language learners studying in a elt institute,in terms of their performance on their achievement test including listening comprehension,vocabulary,grammar,and reading comprehension and found no significant difference between the group except in listening comprehension part of the test in which the f...
this research was conducted to examine the effect of a concurrent training on rest level of leptin of plasma and some hormonal factors in non-athlete subjects. the research population included non-athlete men who didn’t participate in any organized sport activities. 30 men were chosen voluntarily among the above-mentioned population and were divided into 2 groups: experimental (15 subjects) an...
In 1998, Bedau et al. de ned a set of metrics for characterizing the long-term evolutionary dynamics of a system. They argued that no known arti cial system demonstrates the unbounded evolutionary activity observed in the fossil record. In response we have developed a series of toy models that approach and eventually succeed in demonstrating unbounded evolutionary activity. The underwhelming su...

An open-ended carbon nanotube or a tubule is a part of some regular hexagonal tessellation of a cylinder. A tubule T is said to be k-resonant if for every k (or fewer) pairwise disjoint hexagons, the subgraph obtained from T by deleting all the vertices of these hexagons must have a Kekule structure (perfect matching) or must be empty. The 1-resonant tubules can be constructed by an approach pr...
This paper introduces a new classification scheme called “open-ended texture classification.” The standard approach for texture classification is to use a closed n-class classifier based on the Bayesian paradigm. These perform supervised classification, whereby all the texture classes have to be predefined. We propose a new texture classification scheme, one that does not require a complete set...
Background: Manual coding of open-ended survey responses is time-consuming, expensive, and error-prone. However, this task can be recast as a multi-label text classification problem, to which natural language processing and machine learning techniques can be applied. Aim: The aim of this work is to assess the suitability of various machine learning techniques to the problem of automated coding ...
