Abstract(in English) | To use multiple and large amount of lifelogs effectively, we need methods that can efficiently analyze these data. In this report, we propose a novel data mining method that enables us to analyze the data with subtle relationships between different kind of data. We show a method that reveals both the properties of combinations of the items have, and the set consists of the similar terms if a subset of the items are given as a query pattern. The effectiveness of our methods comes from the use of Zero-Suppressed Binary Decision Diagrams(ZBDDs) : a data structure that can represent the set of the combinations of the items with less memory and we can execute some kinds of set operations on them. We show our method can be executed effectively with the use of ZBDDs in experiments using MovieLens data sets. |
