18 / 196Deliverable 2.3: Requirements Specification for the Vertical Industrial Use Case1.2.2 Challenges of Content Management in News MarketsAccording to the relevance of content investigated in the previous section, two challengeshave been derived:1. Extraction of specific information from content items2. Enrichment of content with additional informationIn the following, these challenges are described and domain-specific high-level requirementsare derived for the vertical use case.1.2.2.1 Information Extraction from Content ItemsThe content which is to be analyzed by the journalist can be available in different mediatypes, like photos, images, videos or texts. The task of the journalist is to identify and extractthe relevant information from these content items. An example of a photo from a basketballmatch is given in Figure 6.Player: John DunkingTeam: BasketsFigure 6: Information extraction from photographs [Pixelio2010]The exemplary photograph in Figure 6, shows a scene from a basketball game. A journalist,who is writing an article about this game, may have access to a large repository of such photos.An appropriate content management system should be able to support the journalist byextracting relevant information from the photos to allow an efficient selection and assignmentof the photos. As shown in the example, the identification of the players, e.g. the scorer,could be the goal of the journalist, as he wants to write about this player as the match winner.According to the need of identification of specific entities in cross-media content items, a contentmanagement system for journalists should support recognition algorithms.

The capability ofextracting information from existing content items is a prerequisite for the efficient selectionand reuse of content for authoring purposes.The main challenge for CMS in the news market is to provide appropriate and customisablerecognition algorithms for cross-media content items. The journalist using the CMS should beable to customise the kind of entities that should be extracted according to the context he isworking in.1.2.2.2 Enrichment of Content with additional InformationThe enrichment of content addresses the need of journalists to gather information for an articlehe is authoring. The automatic enrichment reduces the effort for the investigation andsearching of related content. An example of an enrichment scenario is given in Figure 7 anddescribed in the following.Player Information:Name:Height:Weight:John Dunking6 ft 6 in215 lbPlayer Information:Name: John DunkingTeam: BasketsContentenrichmentTeam: BasketsPosition: Shooting Guard-------------------------------Statistics:Avg.

The player “John Dunking” was thebest player of the game and the journalist wants to point out him in the article. He has onlythe name of the player and of his team. The content enrichment functionality is able to retrieveadditional and related information about the topic and provides this information to thejournalist. Thereby the journalist is able to use the results to enrich the existing content withthe retrieved information.The content enrichment includes the retrieval of information from different sources and theenrichment of the existing content with the retrieved information. Figure 8 shows a simplified,abstract content enrichment process.© IKS Consortium2010
