Purpose The purpose of this paper is to complement an available system of qualitative analysis of efficiency of scientific activities with assessment of novelty of a subject of research that gives a more complete pattern for evaluating the efficiency of efforts of both scientists and research teams. Design/methodology/approach The approach is based on detection of specified linguistic patterns with further evaluation of similarity and novelty scores of obtained definitions at the sentence level. Findings This work presents an algorithm of automatic search for a new subject of research in scientific papers on the basis of statistical and linguistic analyses of description of new terms. Application of patterns specified in a given manuscript with further utilization of well-known methods of similarity and novelty detection scores makes it possible to evaluate the degree of novelty of a subject of research. Practical implications As a practical application of the proposed algorithm, the algorithm of determination of authority of a scientist will facilitate assessment of personal contributions of certain authors made in a certain field of study. Originality/value The main contribution of a given manuscript is in application of linguistic patterns recognition and calculation of similarity and novelty scores to the area of scientific results with further proposition of the method of automatic search for a new subject of research in scientific manuscripts.

Purpose This exploratory study aimed to investigate the potential impact of sentence-level comprehension and sentence-level fluency on passage comprehension of deaf students in elementary school. Method A total of 159 deaf students, 65 students ( M age = 13.46 years) in Grades 3 and 4 and 94 students ( M age = 14.95 years) in Grades 5 and 6, were assessed for nonverbal intelligence, vocabulary knowledge, sentence-level comprehension, sentence-level fluency, and passage comprehension. Group differences were examined using t tests, whereas the predictive and mediating mechanisms were examined using regression modeling. Results The regression analyses showed that the effect of sentence-level comprehension on passage comprehension was not significant, whereas sentence-level fluency was an independent predictor in Grades 3–4. Sentence-level comprehension and fluency contributed significant variance to passage comprehension in Grades 5–6. Sentence-level fluency fully mediated the influence of sentence-level comprehension on passage comprehension in Grades 3–4, playing a partial mediating role in Grades 5–6. Conclusions The relative contributions of sentence-level comprehension and fluency to deaf students' passage comprehension varied, and sentence-level fluency mediated the relationship between sentence-level comprehension and passage comprehension.
