Model categorization, the fifth step in the safety model calibration process, is one of the most important steps.
In addition, based on our categorization, the third sub-category of feedback exchanges, social interaction, is classified into two sub-types: on-task and off-task interactional exchanges.
In last year's report, it found that the Thai government does not fully "comply with the minimum standards for the elimination of trafficking" (pdf., p.339), which earned it a "Tier 2 Watchlist" categorization, the second-worst grade a country can get.
During the categorization, the first author read and reread the text repeatedly in order to get immersed in the data.
The first two authors participated in data analysis and categorization; the first author coded data, which was re-checked and discussed by members of the study team.
The positive negative neutral categorization in the second study was aimed to characterize the 272 candidate words and to test for the occurrence of a hedonic asymmetry.
More significant is the power of categorization in the first place: whose definition of a given situation or event as one or other problematization prevails (Deroy and Clegg 2011)?
Moreover, the association between exposure and outcome was assessed using different statistical methods: multiple linear regression that used PCB levels as a continuous variable in two studies (Jacobson et al. 1985 and Winneke et al. 1998) and an F-test for trend that used a four-level cord blood PCB categorization in the third study (Darvill et al. 2000).
To cope with these issues, the first step is based on an unsupervised classification, which provides a first 'rough' categorization of pixels; the second step, based on the segmentation, enables us to extract the geometric shape, and, in turn, to only categorize as archaeological class those pixels belonging to geometrically (rectangular and linear) shaped clusters.
In general, the use of the Klimisch evaluation method resulted in stronger discrepancies among categorizations into the first two ("reliable without restrictions " and "reliable with restrictions") versus the last two reliability categories ("not reliable," "not assignable") (Fig. 1; Additional file 1: part D, Table D1).
