Abstract

The invention discloses a data fusion method and device. The method comprises the steps of extracting attributes in first data and second data, wherein the first data and the second data comprise a corresponding relationship of the attributes and attribute values; calculating semantic similarity values among all the attributes, determining the semantic similarity values larger than a first presetthreshold value, and determining attributes corresponding to all the semantic similarity values as pairs of common attributes of the first data and the second data; determining the similarity value between the first data and the second data by comparing the attribute values corresponding to each pair of common attributes, and fusing the first data and the second data if the similarity value between the first data and the second data is larger than a second preset threshold value. According to the data fusion method and device, on the premise of guaranteeing the accuracy of data fusion, the rate of data fusion is increased.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a data fusion method and device. Background technique [0002] Data fusion is to merge and deduplicate data pointing to the same entity, and finally realize the retention of data pointing to different entities. For example, the song "Wangqingshui" from QQ music is stored in the song library, which contains several attributes, such as the singer Andy Lau, and the song is 4 minutes long; in addition, the song "Wangqingshui" from Xiami Music is also stored in the song library , including singer Andy Lau, release date 1994 and other attributes. Since the two songs are essentially the same song, in order to avoid song query errors, the system needs to fuse the two songs, that is, merge them into one song "Wangqingshui" and store it in the song library. The fused song contains the above All attributes of both songs. [0003] In the process of data fusion, it is necessary to first dete...
