Chinese mobile search engine Sogou Inc. wants to focus on boosting its artificial intelligence capabilities as it plans to publicly float its shares in the U.S., Reuters reported.

Sogou CEO Xiaochuan Wang reportedly said in an internal email that the Sohu.com Inc. unit would aim to lead AI efforts in China by focusing on natural language processing and moving from search to answering questions.

The company would also hike its investments in AI, big data and the internet of things, Reuters said.

Meanwhile, Sogou declined to comment on the possible size of the potential IPO, which earlier reports said could be valued at up to $5 billion. The company plans to file a registration statement for the IPO, which is aimed at stepping up competition with rival search engine Baidu Inc.
