  In this paper, we describe Topic Pages, an inventory of scientific concepts
and information around them extracted from a large collection of scientific
books and journals. The main aim of Topic Pages is to provide all the necessary
information to the readers to understand scientific concepts they come across
while reading scholarly content in any scientific domain. Topic Pages are a
collection of automatically generated information pages using NLP and ML, each
corresponding to a scientific concept. Each page contains three pieces of
information: a definition, related concepts, and the most relevant snippets,
all extracted from scientific peer-reviewed publications. In this paper, we
discuss the details of different components to extract each of these elements.
The collection of pages in production contains over 360,000 Topic Pages across
20 different scientific domains with an average of 23 million unique visits per
month, constituting it a popular source for scientific information.
