Conclusion

Although some of the highly productive authors had a larger co-authorship network and are at the center of co-authorship clusters, a number of single-author publications were heavily cited.

Top five disciplines that contribute to information retrieval are computer science, library and information science, engineering, telecommunications, and management.
