Negation recognition in medical narrative reports 总被引：1，自引：0，他引：1
Substantial medical data, such as discharge summaries and operative reports are stored in electronic textual form. Databases
containing free-text clinical narratives reports often need to be retrieved to find relevant information for clinical and
research purposes. The context of negation, a negative finding, is of special importance, since many of the most frequently
described findings are such. When searching free-text narratives for patients with a certain medical condition, if negation
is not taken into account, many of the documents retrieved will be irrelevant. Hence, negation is a major source of poor precision
in medical information retrieval systems. Previous research has shown that negated findings may be difficult to identify if
the words implying negations (negation signals) are more than a few words away from them. We present a new pattern learning
method for automatic identification of negative context in clinical narratives reports. We compare the new algorithm to previous
methods proposed for the same task, and show its advantages: accuracy improvement compared to other machine learning methods,
and much faster than manual knowledge engineering techniques with matching accuracy. The new algorithm can be applied also
to further context identification and information extraction tasks.

否定是关于陈述句中个别词语或整个陈述的否定过程和结果。否定可分为语义否定和语用否定。语义否定是否定句子表达的命题的真实性，即否定句子的真值条件。而语用否定指的是对语句的适宜条件的否定，否定的是语句的隐含意义或言外之意，即非真值的意义。它是利用语境手段而实现的否定，其实现的过程需要人类的认知参与。在日常话语中，语义否定往往结合使用语用否定．使话语意义更加确定、完善、丰满。 相似文献

“半”的模糊语义不同,其隐含的否定意义也不同,通过系统分析总结出模糊量“半”在不同组合中的弱否定特征：否定部分量、部分性质、部分程度和动词的部分特征,还可否定质变。“半”在表模糊极小量时,只用在否定句中。最后还对强否定“不”和弱否定“半”的语义特征进行了对比。 相似文献

A critical assessment of mass-mediated stereotypes by media users can be deemed as beneficial for an open and humane society. One important concept in this regard is negation, which refers to an internal attempt to negate newly encountered stereotypic media content. This study predicted that disposition-content congruence moderates the negation process. In fact, it investigated whether those whose prejudicial dispositions are congruent with the stereotypic content negate less. An experiment (N = 245) using a quota-based sample was used to test the hypothesis. Participants read stereotypic crime texts including the “criminal foreigner”-stereotype or matched control texts. As hypothesized, unprejudiced readers who held favorable attitudes toward the social minority group negated the stereotypic information. Conversely, highly prejudiced individuals showed even less negation when exposed to the stereotypic versions of the crime texts. Highly prejudiced readers might have viewed exposure to criminal foreigners as a confirmation of their attitudinal predispositions. 相似文献

Up to now, negation is a challenging problem in the context of Sentiment Analysis. The study of negation implies the correct identification of negation markers, the scope and the interpretation of how negation affects the words that are within it, that is, whether it modifies their meaning or not and if so, whether it reverses, reduces or increments their polarity value. In addition, if we are interested in managing reviews in languages other than English, the issue becomes even more problematic due to the lack of resources. The present work shows the validity of the SFU ReviewSP-NEG corpus, which we annotated at negation level, for training supervised polarity classification systems in Spanish. The assessment has involved the comparison of different supervised models. The results achieved show the validity of the corpus and allow us to state that the annotation of how negation affects the words that are within its scope is important. Therefore, we propose to add a new phase to tackle negation in polarity classification systems (phase iii): i) identification of negation cues, ii) determination of the scope of negation, iii) identification of how negation affects the words that are within its scope, and iv) polarity classification taking into account negation. 相似文献
