A never-ending learning system that has a fluent understanding of human language on technologies

Word2Tech builds services on top of a “never-ending learner” that can extract “technological semantics” from text. The learner was trained with hundreds of millions of tech documents and has been learning to understand new technologies 24/7 since then. The learner enables us to provide services to search literatures, and track R&D activities, influential patents, 33M experts, products & competitors within millions of organizations. It also allows us to generate literature review around any tech field or social / economic topic.


We were part of Expert Graph, which was founded in 2021 by Dr. Chang Wang at New York. Our mission is to produce high quality technology related analysis results that people can actually use on a daily basis.

We have the most comprehensive technology data on US companies, schools and research labs.


We maintain the most up-to-date R&D data for more than 3M organizations and 33M experts across all fields of science and technology.

We have developed exclusive semantic analysis techniques to map free text into 200K pre-defined semantic technology categories that machines understand. This allows our system to go beyond keyword matching.


A fairly complicated text analysis platform has been built to support our services. The platform contains: a central knowledge graph storing hundreds of millions of documents; a semantic analysis component to decompose the input into a number of semantic tech categories that machines understand; a semantic search engine to find organizations & experts using business, tech, goods, services, etc.; a number of site crawlers tracking new tech data in real-time; a pipeline with dozens of built-in natural language processing and machine learning components to analyze queries, documents and provide search results with explanations.

Our users come from more than 200 countries or territories across the world. Most of our users are researchers, engineers, tech managers, and professors. Some business men, recruiters, reporters and investors also use our services to read literature review, track the most recent research progresses, analyze companies and find talents.


More specifically, we serve users from hundreds of well-known organizations in industry (e.g. Amazon, Apple, Cannon, Google, IBM, Microsoft, Nvidia, Sony, Visa, etc.) and most top universities across the world (e.g. CMU, Columbia, Harvard, Princeton, Stanford, UCB, Yale, etc.).
