  2. Statement of this topic • RPI Personal Library is a small-scale, personalized digital library oriented to individual student. Unlike the traditional many-to-one model, RPI personal library could provide one- to-one customized service based on students' interests and habits.

  3. Why I choose this research topic • 1 Information needs of the times The whole society has stepped into an era of information economy. The information has become the driving power of social development, and the main capital to create wealth. If the info couldn’t be integrated and innovated, the users will not utilize it effectively. Provide accurate and relevant materials to people based on their preference and usage behavior is one of the most important aspect to improve the quality of information service.

  4. Why I choose this research topic • 2 Survey of RensSearch In the class "Foundations of HCI" last semester, the team I belonged to did a questionnaire survey about RensSearch by using Google document online. We got a conclusion from the survey that it’s difficult for Libraries to meet expectation of people, especially in this era of information explosion. In order to achieve higher quality of service, Folsom should enhance and expand its digital library business by using information technologies.

  5. Why is digital infrastructure important? Providing ordered and standard resources Building digital infrastructure is the first step to achieve personal library service. every operation in the process of constructing user-oriented service must be done on standard and ordered resources.

  6. Why is digital infrastructure important? Providing foundation to intelligent retrieving. From the view of searching relevant information, domain ontology could also be used to unify query keywords, and to describe user's interests in the process of user modeling.

  7. Related Works Extract metadata In order to protect current digital materials, and to make good use of multiple resources, we can encapsulate multiple digital library resources in to a whole metadata base by using XML/RDF.

  8. Related Works Construct Domain Ontology By using information from metadata base, and semantic dictionaries and thesaurus in field of certain subjects, we can construct domain ontology under the help of domain experts.

  9. Related Works Example of a Library Domain Ontology

  10. Related Works Ontology reasoning and updating After constructing domain ontology, we have to find implicit information by doing reasoning process. For example, sometimes a concept can be using in multiple areas, so we should discover the relations and the differences between them, maintaining reasonable logical connections, and avoiding build ontology repeatedly. Tools: SWRL: an inference rule language Jess(Java expert system shell): an efficient reasoning engine.
