This paper presents a brief survey of the current efforts in the Semantic Web literature with respect to
the three research topics of Linked Data, semantic search and search interfaces. First we give a basic
overview about Linked Data, discussing the concepts, principles and examples of relevant initiatives such as Linked Open Data (LOD). Second we review current and relevant work on semantic search, with a particular focus on entity search from different perspectives: entity type identification, entity query suggestions, and entity attributes ranking. Finally we highlight some approaches to semantic search interfaces from two perspectives: the design of search interfaces, and the evaluation of search interfaces. Our survey offers new ways of understanding the evolving connections between Linked Data, semantic search and search interfaces.
