Baidu's Natural Language Processing (NLP) leverages the company's vast data resources to advance innovative technologies in natural language processing and knowledge graphs. This NLP initiative has unlocked several fundamental capabilities and solutions, offering over ten distinct functionalities, including sentiment analysis, address identification, and the assessment of customer feedback. By employing techniques such as word segmentation, part-of-speech tagging, and named entity recognition, lexical analysis enables the identification of essential linguistic components, eliminates ambiguity, and fosters accurate comprehension. Utilizing deep neural networks alongside extensive high-quality internet data, semantic similarity calculations allow for the assessment of word similarity through word vectorization, effectively addressing business scenario demands for precision. Additionally, the representation of words as vectors facilitates efficient analysis of texts, aiding in the rapid execution of semantic mining tasks, ultimately enhancing the ability to derive insights from large volumes of data. As a result, Baidu's NLP capabilities are at the forefront of transforming how businesses interact with and understand language.
