The number of published manufacturing science digital articles available from scientific journals and the broader web has increased exponentially every year since the 1990s. Assimilating all of this knowledge by a novice engineer or an experienced researcher requires a significant synthesis of the existing knowledge space contained within published material to find answers to basic and complex queries. Recent advances in Technical Language Processing (TLP), a sub-field of Natural Language Processing (NLP), have created opportunities to leverage the rich data available from multiple procedural sources, including research articles, magazines, and textbooks, to develop new applications in data-driven manufacturing, education, and data-guided design. TLP enables the extraction of valuable text-based scientific information fast and efficiently using word embeddings. This dissertation focuses on developing tools for enabling information extraction and structured representation of knowledge for the manufacturing science domain.One of the significant challenges to analyzing manufacturing vocabulary is the lack of a named entity recognition model that enables algorithms to classify the manufacturing corpus of words under various manufacturing semantic categories. In this work, we present a supervised machine learning approach to categorize unstructured text from manufacturing science abstracts and content obtained from relevant technical books in discrete manufacturing and label them under various manufacturing topic categories. We created a FabNER dataset and model to perform the manufacturing-specific information extraction. Two use cases in topic modeling and similar entity recommendations demonstrate the value of the developed NER model as a Technical Language Processing (TLP) workflow for manufacturing science documents. The textual data is further used to create the word embeddings of contextual representation through transformers-based language models. To address the limitations of using vanilla language models, we introduce ManuBERT (Bidirectional Encoder Representation from Transformers for Manufacturing text) as an extension of the state-of-the-art BERT model with manufacturing domain-specific language information. We evaluate this language model using the named entity recognition, mask prediction, and binary classification task. Furthermore, the combination of traditional word embeddings and entity recognition is used to conduct unsupervised NLP research on solar cell materials to anticipate new solar cell materials based on existing knowledge present in 1.72 million abstracts and patents.The information extraction tools developed are further used to create a structured representation of manufacturing knowledge through Knowledge Graphs (KG). A KG can power question-answering systems, organize knowledge and infer results through queries. We created FabKG (Manufacturing knowledge graph) by utilizing structured and unstructured knowledge sources. For the structured knowledge, textbook index words, research paper keywords, and FabNER (manufacturing NER) was utilized to extract a sub-knowledge base contained within Wikidata. For the KG developed through unstructured knowledge source, a novel crowdsourcing method for KG creation is proposed by leveraging student notes, which have invaluable information but are not captured as meaningful information, excluding their use in personal preparation for learning and written exams. The knowledge graph developed through notes and human annotations is evaluated by annotators. Finally, some potential use cases and the question types answered through the knowledge graph are shown.
