title = "Theory-informed design and evaluation of an advanced search and knowledge mapping system in nanotechnology",
abstract = "Effective search support is an important tool for helping individuals deal with the problem of information overload. This is particularly true in the field of nanotechnology, where information from patents, grants, and research papers is growing rapidly. Guided by cognitive fit and cognitive load theories, we develop an advanced Web-based system, Nano Mapper, to support users' search and analysis of nanotechnology developments. We perform controlled experiments to evaluate the functions of Nano Mapper. We examine users' search effectiveness, efficiency, and evaluations of system usefulness, ease of use, and satisfaction. Our results demonstrate that Nano Mapper enables more effective and efficient searching, and users consider it to be more useful and easier to use than the benchmark systems. Users are also more satisfied with Nano Mapper and have higher intention to use it in the future. User evaluations of the analysis functions are equally positive.",

note = "Funding Information: Specifically, patent documents are collected from the united States Patent and Trade-mark Office (uSPTO, www.uspto.gov), the European Patent Office (EPO, www.epo .org/index.html), and the Japan Patent Office (JPO, www.jpo.go.jp). Together, these three patent offices issue the majority of nanotechnology-related patents around the world [12]. The uSPTO database supports online full-text access to all the patents issued since 1976. The EPO database offers free access to European patents since 1978. The JPO database consists of the patents issued since 1976. The NSF database supports online title/abstract searches of all the funded projects since 1989, nearly 200,000 grants in total. we used a set of key words provided by domain experts [28] to obtain nanotechnology-related documents from each source database. we collected 97,509 full-text nanotechnology-related patents from the uSPTO database, 3,596 from the EPO database, and 1,150 from the JPO database, as well as 10,114 grant documents from the NSF database. Funding Information: Acknowledgments: This research is supported by the following awards: National Science Foundation, “SgEr: Inter-repository Patent analysis to understand worldwide Nanotechnology research and Development” (cMMI-0738803) and “Mapping Nanotechnology Development” (DMI-0533749). The authors thank the united States Patent and Trademark Office, the European Patent Office, and the Japan Patent Office for making their databases available for research purposes. Funding Information: Following our theoretical foundations (i.e., cFT [64] and clT [58]), and consistent with previous search system interface design research (e.g., [30, 39, 50, 55, 61, 66]), we implemented distinct search functions to support different levels of task complexity. For each document collection, Nano Mapper provides three search functions: patent (grant) number search, quick search, and advanced search. Both patent (grant) number search and quick search constitute basic search functions of Nano Mapper. They aim to support users{\textquoteright}low-complexity search tasks by matching the task with a low-complexity search interface, thus providing better cognitive fit. a patent (grant) number search returns the patent (grant) document with the specified patent (grant) number. a quick search allows users to specify one or multiple key words to be used to search in the document title, abstract, or claims. The advanced search supports high-complexity task-searching demands. It allows users to search patent or grant documents using a combination of search criteria defined over multiple fields of a document. as shown in Figure 2, example fields supported by the advanced search on uSPTO patent documents include patent title, examiner, inventor, assignee, assignee country, classification code, abstract, and claims. In response, Nano Mapper will return a list of patent or grant documents that includes the patent or grant number, title, and publication date, thereby allowing users to review specific articles for details.",
