| Abstract | Web search queries can offer a unique population-scale window onto streams of evidence that are useful for detecting the emergence of health conditions. We explore the promise of harnessing behavioral signals in search logs to provide advance warning about the presence of devastating diseases such as pancreatic cancer. Pancreatic cancer is often diagnosed too late to be treated effectively as the cancer has usually metastasized by the time of diagnosis. Symptoms of the early stages of the illness are often subtle and nonspecific. We identify searchers who issue credible, first-person diagnostic queries for pancreatic cancer and we learn models from prior search histories that predict which searchers will later input such queries. We show that we can infer the likelihood of seeing the rise of diagnostic queries months before they appear and characterize the tradeoff between predictivity and false positive rate. The findings highlight the potential of harnessing search logs for the early detection of pancreatic cancer and more generally for harnessing search systems to reduce health risks for individuals. |

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.
