This book shows ways of augmenting the capabilities of Natural Language
Processing (NLP) systems by means of cognitive-mode language processing.
The authors employ eye-tracking technology to record and analyze shallow
cognitive information in the form of gaze patterns of readers/annotators
who perform language processing tasks. The insights gained from such
measures are subsequently translated into systems that help us (1)
assess the actual cognitive load in text annotation, with resulting
increase in human text-annotation efficiency, and (2) extract cognitive
features that, when added to traditional features, can improve the
accuracy of text classifiers. In sum, the authors' work successfully
demonstrates that cognitive information gleaned from human eye-movement
data can benefit modern NLP.
Currently available Natural Language Processing (NLP) systems are weak
AI systems: they seek to capture the functionality of human language
processing, without worrying about how this processing is realized in
human beings' hardware. In other words, these systems are oblivious to
the actual cognitive processes involved in human language processing.
This ignorance, however, is NOT bliss! The accuracy figures of all
non-toy NLP systems saturate beyond a certain point, making it
abundantly clear that "something different should be done."
