Table 1 shows statistics of the linkage results. Table 2 presents statistics of the evaluation data sets for the Freebase KB. Table 3 shows statistics of our subgraph for training TransE. Table 4 is performance comparison of different pmethods on the task of last-item recommendation. Four tables and three figues of this paper. Figure 1 presents a linkage example of MovieLens 20M items with Freebase entities. Note: We highlight the MovieLens IDs and Freebase IDs. Figure 2 examines the effect of popularity on the linkage results. Note: We use A, B, … to indicate the bin number in an ordered way. The first three subfigures correspond to the popularity analysis on Freebase, and the last three subfigures correspond to the popularity analysis on YAGO. Figure 3 examines the effect of recency on the linkage results. Note: We use A, B, … to indicate the bin number in an ordered way. The first subfigure corresponds to the recency analysis on Freebase, and the second subfigure corresponds to the recency analysis on YAGO.
