Embodiment Construction

[0044] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0045] The invention realizes a dispatching method that uses the update unit as a dispatching unit for calculation. This method is based on the fact that different update units of the same website have different update states and update time points, and cannot be updated at a unified time. For this type of information, if one update unit is used as an information update unit and processed separately, and each update unit counts and uses its own update strategy, each scheduling unit can be updated in a timely and effective manner while reducing download consumption.

[0046] Several concept descriptions in the present invention:

[0047] Entrance: refers to the starting page of a website, through which we can traverse the information of the website. The scheduling module will start periodic scheduling from the entrance, and the extraction module will return ...

Abstract

The invention provides a scheduling method for information units in a vertical search engine. The method is based on a collecting and scheduling system and comprises the following steps: a scheduling module initiates an inlet domain name scheduling; an extraction module identifies the types of an extracted second-level domain and marks; the scheduling module receives the extracted second-level domain and identifies the mark; that the identified information units are updated or not is judged; the domain information, and history update records of the information units are added to or updated to an updating unit page. According to the history update records, a time point, at which next updating occurs is predicted, and information unit scheduling is performed at the time point. According to the invention, in the vertical search, information unit characteristics are provided, and a better application effect on a website with a big difference between the update cycle and the update time point of each information unit is achieved.

Description

technical field [0001] The invention relates to a method for dispatching network information, in particular to a method for dispatching information units in a vertical search engine. Background technique [0002] Now users have a lot of personalized search requirements. Such requirements are generally specific in scope and have high requirements on data quality. Therefore, corresponding search manufacturers have launched vertical searches based on specific directions, such as news search, video search, music search, and Weibo. Search and novel search and so on. These vertical channels have some obvious features: 1. The data type is consistent, the source is very narrow, and almost all of them are directional crawls; 2. The timeliness of data is very high, and they hope to be included in the system as soon as possible; 3. Data needs to be continuously updated; 4. The activity of data updates varies greatly. [0003] With these specific requirements, for the collection syste...
