Building an AI-Powered Writing Assistant for WPS Office

WPS Office is a productivity tool developed by Kingsoft, used by over 150 million users worldwide. The company's AI department built a smart writing assistant using semantic matching algorithms such as intent recognition and text clustering. This tool exists both as a web application and WeChat mini program that helps users quickly create outlines, individual paragraphs, and entire documents by inputting a title and selecting up to five keywords. The writing assistant's recommendation engine uses Milvus, an open-source similarity search engine, to power its core vector processing module. Building the WPS Office smart writing assistant involves making sense of unstructured textual data, using the TFIDF model for feature extraction, extracting features with a bi-directional LSTM-CNNs-CRF deep learning model, creating sentence embeddings using Infersent, and storing and querying vectors with Milvus. AI isn't replacing writers; it's helping them write more efficiently and effectively.
