    Survey of Semantic Search ResearchEetu M¨ akel¨ aSemantic Computing Research Group,Helsinki Institute for Information Technology (HIIT),Helsinki University ofTechnology, Media Technology, and University ofHelsinkieetu. makela@tkk. fi, http: //www. cs. helsinki. fi/group/seco/Abstract. This paper surveys the research field of semantic search, i.e. searchutilizing semantic techniques or search of formally annotated semantic content.The survey identifies and discusses various prevalent research directions in se-mantic search, as well as extracts common methodology used in them.1IntroductionThis paper surveys the research field ofsemantic search, defined for the purpose ofthispaper as either search utilizing semantic techniques or search of formally annotatedsemantic content. The survey is based on reading and exploring some 20 different pa-pers and approaches to semantic search. The material was gathered based on a keywordsearch for ’semantic AND search’ in various publication databases, as well as by goingthrough references in papers already found, and is meant to be a sufficient representativeof the variety of semantic search related research.From the data gathered in the survey, a number of prevalent research directions insemantic search were identified, based on similarity ofresearch goals. These, as well asthe individual approaches that are part ofthem, are described in chapter 2 ofthis paper.Besides research directions, the papers were also analyzed for common methodology.The methods used in the various approaches are noted when they are discussed, but theactual descriptions of the common design patterns are located in chapter 3. The paperends with a chapter drawing conclusions.2Research Directions in Semantic SearchFrom the corpus of research utilized in this survey, five distinct research directionsemerged. While the categories sometimes do not differmuch in methodology, they seemsufficiently separate and coherent with regards to research goals, to be an accurate clus-tering of the research space. The five directions presented are: augmenting traditionalkeyword search with semantic techniques, basic concept location, complex constraintqueries, problem solving and connecting path discovery. All of these are described indetail in the following subchapters.
