This study develops a collocation theory for instructional use, based on theoretical frameworks of linguistics and second language pedagogy. It also creates a comprehensive knowledge base for practical application. Collocations do not exist in isolation. Using the Precision Marker Interconnect concept, collocation resources are constructed based on linguistic ontology and practices in International Chinese Language Education. Collocations are analyzed from syntactic, semantic, and pragmatic perspectives and categorized into logical, formal, and instance levels. Additionally, it formalizes the specific content of collocations through collocation sequences. This paper utilizes the BCC (BLCU Corpus Center, abbreviated as BCC) to extract over 700,000 high-quality collocations, filtered by formalized rules, and adopts a human-in-the-loop approach to validate and optimize the results. This process leads to the development of a knowledge base of over 200,000 collocation pairs to meet teaching needs. The implementation of this knowledge base in International Chinese Language Education has shown promising outcomes.
