Negation recognition in medical narrative reports

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.

Learning under conditions of hierarchy and discipline: the case of the German Army, 1939–1940

To survive in and adapt to dynamic, turbulent, and complex environments, organizations need to engage in learning. This truism is particularly relevant for army organizations in times of war and armed conflict. In this article a case of army operations during World War II is analyzed on the basis of ?rtenblad’s integrated model of the learning organization and Argyris and Schön’s theory of action approach. Among others, it is found that survival of and adaptation to combat conditions is possible through single-loop learning, provided that this learning takes place in an open and productive learning climate. This and other conclusions have important implications for theory and practice of organizational learning under conditions of hierarchy and discipline.

Variability in children’s early reading strategies

The present study examines the development of sight word reading in young children by examining changes in their self‐reported reading strategies over time. A sample of 65 five to seven year olds were asked to read 40 real word items, all carefully matched for letter length and word frequency, on three separate occasions. Changes in the children’s word identifications were measured using immediately retrospective verbal self‐reports. Overall, the results showed some variability in the children’s self‐reported reading strategies. Over time the children relied less on phonological strategies and moved towards reliance on directly retrieving words from memory. This change was most evident in the older children; while both year groups showed similar patterns of shifting reliance from explicit phonological strategies to retrieval, this shift was simply less frequent among the younger children. An analysis of word‐specific changes in reading strategies showed that the older children had a better sight vocabulary for more complex word items. These findings provide further support for Ehri’s mediated phase theory in explaining children’s development in learning to read.
