Description With the explosive growth of digitization, many cultural heritage institutions have been converting physical objects of cultural heritage into digital representation or descriptive representation and to make it publicly available for everyone. The main goal of these institutions is to construct a national identity using cultural heritage. However, the conversion resulted in several issues such as the documents 1) are descriptive in nature, 2) are ambiguous and brief, 3) use dedicated vocabulary, and 4) contain a lot of term variations. Most of the time, the issues are caused by the aggregated fault in annotating the documents. Besides, there is short query problem which is caused by naive user who has little prior background knowledge in cultural heritage domain. In this research, the main aim is to model information access system to overcome partially the issues arising from the documentation process (conversion from physical to descriptive representation) and the background knowledge of the users of digital cultural heritage. Therefore, one types of information access tool which is information retrieval system that allow the user to access, learn, and explore the information on cultural heritage. Basically, the main idea for the information retrieval system is to incorporate the link relationship between terms into the Language Model by extending Dirichlet Smoothing to solve the problems arising from both the documentation process and background of the users. In conclusion, the proposed solution will solve the problems arising from the documentation process and the background knowledge of the users of digital cultural heritage.
