Standardized Hudup dataset based on Movielens 1m

Standardized Hudup dataset receives information from raw data, which is composed of ten units such as “hdp_config”, “hdp_account”, “hdp_attribute_map”, “hdp_nominal”, “hdp_user”, “hdp_item”, “hdp_rating”, “hdp_context_template”, “hdp_context”, and “hdp_sample”. Each unit has particular functions, which is described in the section of data description. Hudup dataset is meta-data which models any raw data with abstract level. The default raw data which is source of Hudup dataset here is Movielens 1M. It is possible to consider that Hudup dataset is secondary data whereas Movielens is primary data. The raw rating data Movielens (GroupLens, 1998) 1M has 1,000,209 ratings from 6,040 users on 3,900 movies (items), which is available at https://files.grouplens.org/datasets/movielens/ml-1m.zip.标准化Hudup数据集从原始数据中获取信息，其由hdp_config、hdp_account、hdp_attribute_map、hdp_nominal、hdp_user、hdp_item、hdp_rating、hdp_context_template、hdp_context以及hdp_sample等十个单元构成。每个单元均具备特定功能，相关说明详见数据描述章节。Hudup数据集属于元数据（meta-data），能够以抽象层级对任意原始数据进行建模。本数据集默认的原始数据来源为Movielens 1M。可以将Hudup数据集视为二次数据，而Movielens则为一手原始数据。Movielens 1M原始评分数据（GroupLens，1998）包含来自6040位用户对3900部电影（条目）的1000209条评分，该数据集可从https://files.grouplens.org/datasets/movielens/ml-1m.zip获取。
