display _ name: a material injection machine,

equipment_id：“e_filler”}

wherein, the subject feature may be "process _ segment"; the attribute feature may be "display _ name" or "equipment _ id"; and the attribute information is usage data of "injector" and usage data of "e _ filer".

the usage u (< r1, r2 …, rd > | d ≦ δ) of the multi-hop association { < r1, r2 …, rd > | d ≦ δ }, wherein the number of bars δ is a system parameter;

entity and attribute (e.g., e1. A1) as the usage u of the return attribute _a―ret (e1.a1)；

Use of entities and attributes (e.g., e1. A1) as IS NULL or IS NOT NULL filter attributes u _a―null (e1.a1)；

Entity and attribute (e.g., e1. A1) usage u as a value filtering attribute that IS NOT IS NULL or IS NOT NULL filtered _a―pred (e1.a1)

The usage u as the set of attributes of the Distingt clause (i.e., return attributes such as { e1.A1, e1.A2, …, e1.A { n } }) _as―dist (e1.a1，…，e1.an)；

Usage u as a set of attributes of packet clauses (e.g., { e1.A1, e1.A2, …, e1.A { n } }) _as―grp (e1.a1，…，e1.an)。

For example, the sliding window size is denoted as W and the step size is denoted as S. In practice, for example, W, S may be selected to be 1 month, 1 day (or 1 week, 1 hour). For each time period (e.g., 1 hour) of the sliding window step, the usage of the target current request field is calculated and stored. Element usage is reserved in the system for all step periods (e.g., 1 hour) within a window-sized period (e.g., 1 week), a set of target current request fields for one step period (1 hour) is newly generated and reserved as the window slides forward (in the future direction) for one step, and the oldest set of target current request fields for one step period (1 hour) and above is planed.
