摘要： The present invention proposes a temporally-controlled item recommendation method and system based on rating prediction. According to this invention, the item recommendation method comprises inputting an item to be recommended; determining a temporal rating model related to the item, the temporal rating model being used to predict variation of the rating of the item with time; applying one or more recommendation strategies to the determined temporal rating model to determine optimal recommendation times of the item; and recommending the item to a user at the determined optimal recommendation times. In different embodiments, the temporal rating model of the item can be selected from a set of pre-stored temporal rating models or automatically generated according to history data in the system. In addition, the selected temporal rating model can be adjusted in accordance with user preference information or user feedback information. The item recommendation system of this invention is able to consider the change of a user's interest in a given item with time so as to increase the effectiveness of recommendations and improve user experience.

摘要： A full-text data base retrieving device retrieves a data base in accordance with a query. A full-text index has character location information representative of location of each of key character sequences of N characters that appear in the data base, where N is a positive integer. A query memory memorizes the query as a retrieval key character sequence. A separating section separates the retrieval key character sequence into a plurality of retrieval key character sequences of N characters to extract contexts as extracted contexts from the retrieval key character sequence in accordance with the retrieval key character sequences. A context classifying section classifies the extracted contexts into classified contexts having the classification numbers, respectively. An index retrieving section retrieves the full-text index in accordance with the sorts of the retrieval key character sequences and the classified contexts to read the character location information as a retrieval result out of the full-text index. A detecting section detects appearance locations of the retrieval key character sequence in the full-text data base to produce the appearance locations as a detected result.
