Abstract | Headlines are particularly important for online news outlets where there are many similar news stories competing for users' attention. Traditionally, journalists have followed rules-of-thumb and experience to master the art of crafting catchy headlines, but with the valuable resource of large-scale click-through data of online news articles, we can apply quantitative analysis and text mining techniques to acquire an in-depth understanding of headlines. In this paper, we conduct a large-scale analysis and modeling of 150K news articles published over a period of four months on the Yahoo home page. We define a simple method to measure click-value of individual words, and analyze how temporal trends and linguistic attributes affect click-through rate (CTR). We then propose a novel generative model, headline click-based topic model (HCTM), that extends latent Dirichlet allocation (LDA) to reveal the effect of topical context on the click-value of words in headlines. HCTM leverages clicks in aggregate on previously published headlines to identify words for headlines that will generate more clicks in the future. We show that by jointly taking topics and clicks into account we can detect changes in user interests within topics. We evaluate HCTM in two different experimental settings and compare its performance with ALDA (adapted LDA), LDA, and TextRank. The first task, full headline, is to retrieve full headline used for a news article given the body of news article. The second task, good headline, is to specifically identify words in the headline that have high click values for current news audience. For full headline task, our model performs on par with ALDA, a state-of-the art web-page summarization method that utilizes click-through information. For good headline task, which is of more practical importance to both individual journalists and online news outlets, our model significantly outperforms all other comparative methods. |

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.
