为了对新闻媒体平台的重大事件进行话题演化建模分析,基于隐含狄利克雷分布(LDA主题模型算法)对话题动态建模,在变分推断主题模型基础上建立衡量话题内容和热度变化的流行话题模型(TTM-OLDA)。针对用户关注的重大新闻事件发展方向与热度,提出话题内容向量与流行因子,对整个话题生命周期进行量化,从而有效地从大量相关新闻中挖掘出话题演化细节,帮助用户更好地掌握话题发展情况。在特定新闻板块筛选的数据集下,通过设置对比实验和人工评测方式,验证该方法在困惑度上优于在线主题模型算法。  相似文献

This study assessed the ability of history students to choose the essay topic on which they can get the highest score. A second, equally important question was whether the score on the chosen topic was more highly related to other indicators of proficiency in history than the score on the unchosen topic. Overall, for both U.S. and European history, scores were about one third of a standard deviation higher for the preferred topic than for the other topic. For U.S. history, about 32% of the students made the wrong choice; that is, 32% got a higher score on the other topic than on the preferred topic. In European history, 29% made the wrong choice. In the U.S. history sample, the preferred essay correlated .40 with an external criterion score, compared to .34 for the other essay; in the European history sample, the preferred essay correlated .52 with the external criterion, compared to .44 for the other topic.  相似文献

This paper deals with the statistical modeling of latent topic hierarchies in text corpora. The height of the topic tree is assumed as fixed, while the number of topics on each level as unknown a priori and to be inferred from data. Taking a nonparametric Bayesian approach to this problem, we propose a new probabilistic generative model based on the nested hierarchical Dirichlet process (nHDP) and present a Markov chain Monte Carlo sampling algorithm for the inference of the topic tree structure as well as the word distribution of each topic and topic distribution of each document. Our theoretical analysis and experiment results show that this model can produce a more compact hierarchical topic structure and captures more fine-grained topic relationships compared to the hierarchical latent Dirichlet allocation model.  相似文献

While prior knowledge of a passage topic is known to facilitate comprehension, little is known about how it affects word identification. We examined oral reading errors in good and poor readers when reading a passage where they either had prior knowledge of the passage topic or did not. Children who had prior knowledge of the topic were matched on decoding skill to children who did not know the topic so that the groups differed only on knowledge of the passage topic. Prior knowledge of the passage topic was found to significantly increase fluency and reduce reading errors, especially errors based on graphic information, in poor readers. Two possible mechanisms of how prior knowledge might operate to facilitate word identification were evaluated using the pattern of error types, as was the relationship of errors to comprehension. Implications of knowledge effects for assessment and educational policy are discussed.  相似文献

This paper studies the teacher perceived applicability of historical topics for interpretational history teaching and the criteria teachers use to evaluate this applicability. For this study, 15 expert history teachers in the Netherlands striving for interpretational history teaching were purposefully selected. Teachers were asked to mention historical topics using a ranking task technique to rank topics in order of applicability and to elaborate on how the topics were ranked. The results showed a large variation in perceived applicability among topics, both within and between teachers. Eight different topic-applicability criteria were discerned in the teachers’ elaborations: (1) topic knowledge; (2) topic affinity; (3) topic constructedness; (4) topic deconstructability; (5) topic abstractedness; (6) topic sensitivity; (7) topic materials; and (8) topic inclusion in the history curriculum. We found that teachers tended to judge topics as applicable for interpretational history teaching partly depending on the degree of ‘canonised interpretativity’ in lesson materials and the curriculum, and to the degree to which they belonged to ‘cold’ (morally neutral) or ‘hot’ (morally sensitive) history. A theoretical implication of the findings is that interpretational history teaching is topic-dependent. Teachers can be supported to teach history as interpretation by structured pedagogies.  相似文献

The effects of topic knowledge, text coherence, and topic interest on learning from text were examined. One hundred sixty high school students participated in 1 of 4 groups according to their levels of topic knowledge and interest. Participants read 1 of 3 versions of a scientific text: minimally coherent, locally coherent, and locally and globally coherent. Text comprehension was examined by tasks aimed at tapping both textbase and situation-model levels. The contribution of topic interest seemed to increase according to the quantity of learners' topic knowledge. High-knowledge and high-interest students performed significantly better than those in the other 3 groups in all tasks. Text version differentiated students' performance on all measures but 1. The expected Group x Version interactions did not emerge.  相似文献

Students studied instructional materials under two choice conditions. In one case, students were free to choose the topic of study from six alternatives; in the other, the topic was assigned randomly. In addition, some of the students received immediate tests on the materials while the others took placebo tests. When free to choose the topic, students had higher affect for the material, showed greater willingness to continue work on the topic later, and spent more time studying the materials. While the presence of an immediate test increased delayed retention, freedom to choose the topic did not. A measure of students’ perceptions of the amount of freedom they felt in the choice and no-choice situations suggested that they felt relatively but not absolutely freer when able to choose the topic. Apparently, the relative increase in feeling of freedom was sufficient to influence affective but not cognitive outcomes.  相似文献
