[Purpose/significance] The construction of Technological Innovation Service Platform is heavily reliant on intelligent search engine, and the key lies in automatic semantic annotation. While the general search engine could not fully fill the requirements the platform asks, and it mainly deals with texts in professional fields. With semantic annotation technology, we can quickly get the documents of an enterprise semantically organized and structured so as to provide precise knowledge services to users. [Method/process] This paper conducts an in-depth research towards the issues related to key technologies and application of intelligent search engine, based on the fact that semantic annotation can be understood as the semantic organization of a set of documents. Therefore, this paper proposes a method to automatically annotate digital text fragments by extracting some key concepts to form a concept set based on occurrence frequencies, positions and relations between concepts or instances, with the help of structural semantic concepts resources or collections. [Result/conclusion] Then, we evaluated the experiment result, and conducted application research in automatic composition. At the same time, the update and evolution of ontology and semantically annotated fragments form a virtuous cycle of continuous process improvement. This paper aims to provide a useful reference to the automatic semantic annotation for professional literature.
