The iBT, on the other hand, focuses more on moderate-scope items (i.e., those requiring the processing of an entire paragraph (or close to it)), with this level of scope proving to be the most common one.
The GEPT-A has a more even distribution in scope across its items than does the iBT, with a much lower proportion of narrow-scope items than the iBT.
Figures 5 and 6 illustrate the relative percentage of SV and LV scoped items in the cache-hit resulting data items.
Taking into consideration the suitability of different cache replacement policies for SV and LV scope categories, we split the physical cache into two parts, one catering for the SV scoped context data items and the other for LV scoped items.
This policy is biased towards replacing an SV scoped item from the cache store because the validity expiry time for such items is more than likely to be closer than LV items.
While some users may not mind being shown targeted ads to help them pick out a new TV, this example brushes over the full scope of items being marketed to you based on your data.
In his 15 years with Value Village he has worked to grow the company's recycling division, expanding the scope of items diverted from landfills from three categories to almost 20, including plastics, metals, sporting goods and kitchenware.
The selected guidelines were scored using the AGREE instrument, which uses 4-point scales for each item: scope and purpose (3 items), stakeholder involvement (4 items), rigour of development (7 items), clarity and presentation of the recommendations (4 items), applicability of the guideline (3 items), and editorial independence (2 items).
The caching strategy is then configured to utilize OF replacement policy for SV scoped data and SE policy for LV scoped data items.
In this sense, the nature and scope of item selection is unimportant provided that the item set is sampled to provide appropriate domain coverage.
Contrastingly, under the SE policy, LV scoped data items occupy a greater share of the context-hit space i.e. under the SE policy it takes a 30% share in the case of 0.75 SV/0.25 LV, 58% in case of 0.5 SV/0.5 LV and a 80% share in the case of 0.25 SV/0.75 LV (see Figure 6 ).
