Many Natural Language Processing (NLP) techniques have been used in Information Retrieval. The results are not encouraging. Simple methods (stopwording, porter-style stemming, etc.) usually yield significant improvements, while higher-level processing (chunking, parsing, word sense disambiguation, etc.) only yield very small improvements or even a decrease in accuracy. At the same time, higher-...
After studying linguistics, Dr. Chapman received her PhD from the University of Utah in Medical Informatics with a research focus in natural language processing (NLP). She spent ten years at the University of Pittsburgh and moved to the University of California, San Diego in 2010. Dr. Chapman's work has mainly addressed extraction of information from clinical reports, including identifying evid...
Evaluating natural language processing (NLP) systems in the clinical domain is a difficult task which is important for advancement of the field. A number of NLP systems have been reported that extract information from free-text clinical reports, but not many of the systems have been evaluated. Those that were evaluated noted good performance measures but the results were often weakened by ineff...
Neuro-Linguistic Programming (NLP), an emergent, contested approach to communication and personal development created in the 1970’s, has become increasingly familiar in education and teaching. There is little academic work on NLP to date. This article offers an informed introduction to, and appraisal of, the field for educators. We review the origins of NLP, and summarise its nature as a method...
In the NLP context identification has become a prominent way to overcome syntactic and semantic ambiguities. Ambiguities are unsolved problems but can be reduced certain level. This ambiguity reduction helps improve quality of several processes, such as text translation, simplification, retrieval, word sense disambiguation, etc. Context identification, also known contextualization, takes place ...

Structured data on customer feedback is becoming more costly and timely to collect organize. On the other hand, unstructured opinionated data, e.g., in form of free-text comments, proliferating available public websites, such as social media blogs, forums, websites that provide recommendations. This research proposes a novel method develop knowledge-based recommender system from (text) data. Th...
Crowdsourced applications to scientific problems is a hot research area, with over 10,000 publications in the past five years. Platforms such as Amazons Mechanical Turk and CrowdFlower provide researchers with easy access to large numbers of workers. The crowds vast supply of inexpensive, intelligent labor allows people to attack problems that were previously impractical and gives potential for...
