Several methods are proposed for mapping free text into standard terms defined by the Unified Medical Language System (UMLS). For example, natural language processing techniques are used to map identified noun phrases into concepts. They are, however, not appropriate for real time applications. Therefore, in this paper, we present a new algorithm for generating all valid UMLS concepts by permuting the set of words in the input text and then filtering out the irrelevant concepts via syntactic and semantic filtering. We have implemented the algorithm as a web-based service that provides a search interface for researchers and computer programs. Our preliminary experiment shows that the algorithm is effective at discovering relevant UMLS concepts while achieving a throughput of 43K bytes of text per second. The tool can extract key concepts from clinical texts for ind...

The ADEPT team has created a digital learning environment (DLE) that adds educational value to a digital library by offering a suite of services for teaching. Encouraged by the results of implementations in undergraduate geography classrooms, the team now shifts its focus from experimental prototype to deployable system. Everett Rogers' Diffusion of Innovations theories are used as frameworks for analyzing this complex transition. Recommendations for lowering the barriers to adoption related to complexity, trialability, and observability include the prioritization of development efforts focused on stabilizing the system, the creation of documentation and an online demonstration, and anonymous logins to the system. To increase perceived relative advantage, existing technical and copyright issues in integrating the Alexandria Digital Library must be overcome. To increase compatibility, the speed at which pedagogical change is achieved must be rethought. Finally, recruitment efforts should focus on innovators and early adopters before moving on to early majority, late majority, or laggard adopters.

The ADEPT education and evaluation team interviewed professors about their use of geography information as they prepare for class lectures, as compared to their research activities. We found that professors desired the ability to search by concept (erosion, continental drift, etc.) as well as geographic location, and that personal research collections were an important source of instructional materials. Resources in geo-spatial digital libraries are typically described by location, but are rarely described by concept or educational application. This paper presents implications for the design of an educational digital library from our observations of the lecture preparation process. Findings include functionality requirements for digital libraries and implications for the notion of digital libraries as a shared information environment. The functional requirements include definitions and enhancements of searching capabilities, the ability to contribute and to share personal collections of resources, and the capability to manipulate data and images.

We interviewed nine geography faculty members who teach undergraduate courses about their information seeking for research and teaching and their use of information resources in teaching. These data were supplemented by interviews with four faculty members from another ADEPT study about the nature of knowledge in geography. Among our key findings are that geography faculty are more likely to encounter useful teaching resources while seeking research resources than vice versa, although the influence goes in both directions. Their greatest information needs are for research data, maps, and images. They desire better searching by concept or theme, in addition to searching by location and place name. They make extensive use of their own research resources in their teaching. Among the implications for functionality and architecture of geographic digital libraries for educational use are that personal digital libraries are essential, because individual faculty members have personalized approaches to selecting, collecting, and organizing teaching resources. Digital library services for research and teaching should include the ability to import content from common office software and to store content in standard formats that can be exported to other applications. Digital library services can facilitate sharing among faculty but cannot overcome barriers such as intellectual property rights, access to proprietary research data, or the desire of individuals to maintain control over their own resources. Faculty use of primary and secondary resources needs to be better understood if we are to design successful digital libraries for research and teaching.
