**Foreword**
With the rapid advancement of mobile internet technology, machine learning, and the accumulation of big data, natural language processing (NLP) has experienced significant evolution. More and more tech giants have recognized the potential of this field and are investing heavily in research, partnerships, and acquisitions to expand their presence in NLP. This has led to a fierce competition where companies are not only trying to dominate the market but also to establish themselves as industry benchmarks.
At the same time, emerging startups are making waves by offering innovative solutions in areas such as intelligent interaction, speech recognition, and machine translation. These companies are striving to carve out their own space in the vast landscape of NLP, aiming to create new standards and push the boundaries of what is possible.
Artificial intelligence has become a familiar concept for many, but most people still have only a superficial understanding of NLP. By tracing the history of NLP, this paper explores the major transformations that occurred in 2015, identifies current challenges, and outlines future directions for the development of this crucial technology.
**I. Tracing Back to the Source – The Development of Natural Language Processing Technology**
Since its inception at the 1956 Dartmouth Conference, artificial intelligence has aimed to enable machines to perform intellectual tasks. One of the key goals has been to allow machines to communicate with humans in a more natural and efficient way, understanding human language and interacting in a manner that feels familiar.
Over the past two decades, the rise of the internet has driven strong demand for NLP technologies. As these technologies have advanced, they have also significantly enhanced core internet capabilities. For example, information retrieval, a fundamental function of search engines today, has improved greatly due to better natural language understanding. In the early days of the internet, a search for "kimono" might return results about shoes and clothing, but modern systems now provide much more accurate results thanks to NLP advancements.
In recent years, many tech giants have made strategic moves in this space. Google acquired Wavii in 2013, a company known for its NLP capabilities. Microsoft integrated NLP into its virtual assistants like Xiao Bing and Cortana, while Facebook used it to power its AI assistant M. These developments show how NLP is becoming a central component of digital services.
**II. The Development of Natural Language Processing Technology – Continuous Exploration and Steady Progress**
2015 marked a pivotal year for NLP. With the rise of deep learning algorithms and the availability of large-scale data, the field saw remarkable progress. Major players focused on solving complex issues in speech recognition, semantic understanding, and intelligent interaction, continuously refining their models and algorithms.
New products introduced in 2015, such as Baidu’s robot and Rokid’s smart assistant, showcased the growing integration of NLP with physical devices. These robots could understand user input, analyze information, and interact in a more natural way. They were also capable of integrating with smart home systems, enhancing user experience through voice commands and gesture-based interactions.
Far-field speech recognition also saw breakthroughs, allowing users to interact with devices from greater distances. Innovations in microphone arrays and noise suppression techniques significantly improved the accuracy of voice recognition, especially in quiet environments. Chinese speech recognition, in particular, achieved a near-97% accuracy rate, demonstrating the power of deep learning in handling complex linguistic structures.
Moreover, the introduction of “root embedding†improved the performance of Chinese NLP tasks, enabling machines to better understand user intent. Data-driven dialogue systems also gained traction, with models like Deep Match CNN and Neural Responding Machine achieving impressive results in generating natural conversations.
Many companies also opened up their NLP tools to the public. Facebook released open-source deep learning libraries, while Google, Microsoft, and IBM launched their own platforms. These tools are now widely used across industries, driving innovation and improving the efficiency of NLP applications.
As NLP continues to evolve, it is clear that the technology will play an even more critical role in shaping the future of human-computer interaction.
