Description

Apparatus and Method for Recommending Customized History Information According to User Characteristics The present invention relates to a history information recommendation technology, and more specifically, to a device that recommends customized history information based on user characteristics. Research is currently underway to analyze user groups and identify their characteristics by utilizing existing personalized service delivery technologies that provide information by allowing users to set keywords or categories and searching for the set keywords or types. The time consumption required for internet users to seek out new areas is further increased, and from the perspective of service providers, there are problems such as economic losses from operating systems that are not used or have low usage frequency, as well as the need for investment to continuously expand system capacity. In particular, the aforementioned service provision method provides information that is too broad or too narrow depending on the range of keywords specified by the user, so it not only requires a lot of time to find the desired information but also has the problem of obtaining accurate information. On the other hand, there is a need for research that minimizes the time required to find desired information and selects specific historical records from among numerous records by prioritizing the output of preferred historical information based on user characteristics and the number of historical records viewed. The background technology of the present invention is disclosed in Korean Registered Patent No. 10-2298585. FIG. 1 is a drawing illustrating a customized history information recommendation device based on user characteristics according to an embodiment of the present invention. FIG. 2 is a drawing for explaining the recommendation system section of a customized history information recommendation device according to user characteristics according to an embodiment of the present invention. FIG. 3 is a diagram illustrating history data of a customized history information recommendation device according to user characteristics according to an embodiment of the present invention. FIG. 4 is a diagram illustrating a method for recommending customized history information based on user characteristics according to an embodiment of the present invention. FIGS. 5 and 6 are drawings for explaining the calculation process of a method for recommending customized history information based on user characteristics according to an embodiment of the present invention. The present invention is susceptible to various modifications and may have various embodiments. Specific embodiments are illustrated in the drawings and described in detail in the detailed description. However, this is not intended to limit the present invention to specific embodiments, and it should be understood that it includes all modifications, equivalents, and substitutions that fall within the spirit and scope of the invention. In describing the present invention, detailed descriptions of related prior art are omitted if it is determined that such detailed descriptions would unnecessarily obscure the essence of the invention. Furthermore, singular expressions used in this specification and claims should generally be interpreted as meaning "one or more" unless otherwise stated. Throughout the specification, when it is stated that a part is "connected (connected, in contact, combined)" with another part, this includes not only cases where they are "directly connected," but also cases where they are "indirectly connected" with other members interposed between them. Furthermore, when it is stated that a part "includes" a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but rather allows for the inclusion of additional components. The terms used herein are merely for describing specific embodiments and are not intended to limit the invention. Singular expressions include plural expressions unless the context clearly indicates otherwise. In this specification, terms such as “comprising” or “having” are intended to indicate the presence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof. The present invention will be described below with reference to the attached drawings. However, the present invention may be implemented in various different forms and is therefore not limited to the embodiments described herein. Furthermore, in order to clearly explain the present invention in the drawings, parts unrelated to the explanation have been omitted, and similar parts throughout the specification have been given similar reference numerals.
