| Abstract | The objective of this research is to study the technology main paths by adding missing citations through the use of bibliographic coupling (BC) and co-citation (CC). Core patents are identified and used for patent citation network (PCN) analysis. In the citation network, patents with strong links are analyzed to construct the technology main paths. Previous researches have shown that both bibliographic coupling and co-citation may help in finding missing citation patents, so this study will utilize bibliographic coupling and co-citation to add missing citations into the original citation network and construct the technology main paths in the field of photovoltaic by connecting the strong links. The time duration of main paths from the original photovoltaic patent network has been relatively short. Furthermore, the number of patents has not exceeded three. A possible reason to explain the short time duration may be the nature of patents that is focused on technological innovation. On the contrary, the photovoltaic network after adding the missing citations has contained more links and presented a more complete trail for the main paths. Moreover, the network has sustained for longer in time duration. The results indicate that utilizing BC and CC methods to supply missing citations is an effective way in constructing the technology main paths. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
