| Outline of Final Research Achievements |
This report describes the development and evaluation of a "Latent Variable Model" (LVM) classifier that detects evidence for specific human values at either the passage or full-document level. To determine suitability for a specific application, an extrinsic evaluation method reflecting the use of the classification results for content analysis was performed. To extend the utility of the technique, the relationship between words and human value was analyzed to discern patterns of language use. To characterize the versatility of the classifier, new test collections containing newspaper articles about the Fukushima Daiichi nuclear power disaster were developed in which human values were manually assigned as a gold standard at document level. Results obtained on these collections has informed the design of future test collections in which human annotation will be performed at sentence level and multiple categories.
