Abstract: A method of generating content information that matches at least one stored keyword is described. At least one keyword associated with content information is stored. At least one previously searched keyword in a search record is matched with the at least one stored keyword associated with the content information. First-category mapping data is generated based on a first mapping between the matched at least one stored keyword and the at least one previously searched keyword. Second-category mapping data is generated based on the content information and the at least one stored keyword. A received target keyword is determined to be included in the first-category mapping data. In response to the received target keyword, which is included in the first-category mapping data, circuitry of a terminal searches for the content information associated with the target keyword in the second-category mapping data and displays the content information.

Abstract: A method for data retrieval is described. Interface circuitry of an information processing apparatus receives a request for data retrieval from a database. The database stores content sharing information in a social network. The request includes a first user identifier and a first link identifier. The processing circuitry determines whether the first user identifier and the first link identifier are associated in the database as a consequence of a previous sharing of a first article corresponding to the first link identifier using the first user identifier. Further, when the first user identifier and the first link identifier are determined to be associated, the processing circuitry searches for a first message identifier in the database. The first message identifier identifies a first message that includes information of the previous sharing of the first article. The processing circuitry then retrieves the first message according to the first message identifier.

Abstract: A method for relieving the symptoms of arthritis externally is described. The method involves the use of sliced ginger root, moxa, produced from mugwort, and a needle. Freshly cut ginger roots are sliced into slices approximately one centimeter thick and placed on the skin near the area afflicted with arthritis. The moxa, preferably in the form of a rolled moxa cigar, is stood vertically atop the slice of ginger and ignited. The moxa cigar is permitted to burn down to the surface of the slice of ginger, heating the ginger as well as the skin of the patient. Due to the heat, the skin of the patient is blistered. After a duration of time, the ginger slice is removed from the skin, the blister is punctured with a needle, and allowed to heal. This process leaves the patient free of arthritis-induced pain or similar symptoms.
