摘要:
An information processing apparatus, method and computer program product cooperate to provide graphical trends of posts regarding a posting subject and additional information. The apparatus includes a collector that collects posts regarding a posting subject that proceeds over time. A counting unit is included that counts a number of collected posts for each of different classes of posts. A display controller causes graphs to be displayed along a time-axis illustrating time-wise trends in the posts for each class together with additional information. The additional information is information that includes at least one of posts at respective times and information regarding the posting subject.

An information processing apparatus learning a preference of a user for a content item includes acquiring means for acquiring an operation or expression of the user for a certain content item as feedback information; training data generating means for generating training data for the preference learning from the feedback information acquired by the acquiring means; and learning means for learning the preference of the user and how to attach a meaning to the feedback information in association with the training data by using multiple pieces of training data generated by the training data generating means.
摘要:
A method visually and clearly manages and displays a large amount of gene expression data obtained using a large number of DNA chips. The types of DNA chip are displayed in a leftmost column of a matrix, parameters such as times in a time series, treatment methods, types of samples, and the like are displayed in the top row, and expression value data corresponding to the respective cells are displayed as small matrices. Treatment methods or types of samples of Channel 1 and Channel 2 are displayed in the rows and columns of the small matrices. When a cell in a small matrix is clicked, a scatter diagram for corresponding expression value data is displayed.
摘要:
The present invention relates to an information processing apparatus, an information processing method, and a program in which a content piece matching preference information of a user or a content piece similar to a specified content piece can be searched for with a smaller amount of computation and can be provided to the user. Each of items of metadata (such as title, artist name, genre, review text, tempo, beat, and rhythm) of music is classified into any of cluster layers (first to n-th layers), and is classified (clustering) into a plurality of clusters provided in the cluster layers into which actual information of each of the items is classified. Then, instead of the metadata, cluster information including cluster IDs (such as CL11 in FIG. 2) of the clusters into which actual information of each of the items of metadata is classified is compiled in a database as information indicating the features of music. The present invention can be applied to a homepage server for recommending a purchase of content such as music data, a video recorder for recommending a recording reservation of a television program, and the like.
摘要:
An information processing apparatus and an information processing method, a recording medium, and a program make it possible to generate a positive history vector and a negative history vector. A negative history vector is generated from initially registered contents. If the initially registered contents are not changed, and an operation log is supplied, whether or not the supplied operation log is a positive history is determined. When the supplied operation log is a positive history, a program vector corresponding to the operation log is additionally stored as a positive history, and a positive history vector is generated from a sum of program vectors. When the supplied operation log is a negative history, a program vector corresponding to the operation log is additionally stored as a negative history, and a negative history vector is generated from a sum of program vectors.
