Due to the open technology environment, service environment such as broadcasting/communication integration, and the evolved content consumption structure, there is an increasing need for an environment where necessary content can be easily found and consumed. That's why we developed a customized content recommendation technology based on the user's characteristics and situations. In this example, we explored and developed a user-tailored broadcast content recommendation search for broadcast video and related content using language analysis, search, mining, and semantic technologies.

The broadcast content recommendation search system is composed of four systems, including data collection, content search, content recommendation, API server. They can be divided into independent systems. These independent systems are classified into data collection, content indexing, content analysis, content navigation, content search, user analysis, and content recommendation.


Project Information
  1. Content and preference data platform: Managing collection and storage of broadcast metadata and related information at KBS for content analysis, user profile information for broadcast analysis, broadcast service history, and user feedback information.
  2. Recommended Search Platform: By analyzing the content consumption history data of the user, the degree of similarity in patterns between two users who consumed different kinds of content is derived, and the subsequent content recommended search result is provided.
  3. Recommended search algorithm development: Two algorithms are implemented. One is a content-based algorithm that recommends content based on a user's input (search term, menu, content). This is done by analyzing the similarity or association between contents based on the characteristics of the collected content metadata. The other is a recommendation algorithm based on users' personal preferences and profiles. It uses a user-based collaborative filtering technique and an item-based collaborative filtering technique.
  4. Recommended Search Management: Implementing data and service management features required for recommendation systems, such as collection management, index management, project management, API management, and content management.
  5. Recommended Search Utilization Service: Develop recommendation search interface and implement utilization services such as program-related menu and related recommendation page, content/keyword/person-based recommendation search, customized recommendation work, and recent recommendation work.
