Frequently, assigning categories to items i nvolves judgment calls which may be error prone or subject to shifts in perspect ive. For example, if 10,000 tasks are to be categorized according to 15 task typ es, an incorrect or not preferred category may be assigned to a task as a result of, for example, a misunderstanding or misinterpretation of the task or the ava ilable categories. Often, there may be inconsistencies in how items are categori zed if, for example, different persons are categorizing the tasks and each inter prets items or categories slightly differently, if the same person views items s lightly differently on different days, and/or if a person’s interpretation of ta sks and categories evolves during the process. A person’s categorization of his or her one thousandth item may be more informed, performed with a different degr ee of care, and/or approached differently from the person’s approach in categori zing his or her tenth or hundredth item, such that the same item might be catego rized one way if encountered at one point in time, but differently if encountere d by the same person at another point in time. Moreover, reviewing the quality of categorizations also tends to be time consuming and inconsistent. For example, different persons checking and rechecking prior categorizations at different ti mes and with different perspectives may catch some obvious errors or otherwise r efine categories for certain items, but may do so inconsistently, as the review may also be performed by multiple people with varying and/or evolving perspectiv es and approaches over potentially many days, weeks, or months. Sometimes, an or iginal categorization of an item may be preferable over a recategorization durin g quality review by the same person (but, e.g., on a different day) or by anothe r person (who may, e.g., have a different perspective or approach).”
