purpose: this paper introduces an amino acids industry knowledge service platform, which integrates industry data, science literature, and technology knowledge from patents.

design/methodology/approach: from the perspective of knowledge organization, the amino acids industry knowledge service platform comprises a basic data layer, a knowledge representation layer, and a knowledge service layer. the platform integrates heterogeneous information sources by means of a multi-dimensional integration index. it enables users to find technology knowledge from patents by employing the semantic theory of inventive problem solving (triz).

findings: this paper constructs an integrated amino acids industry database, which offers a general service oriented to the public, and a technical innovation knowledge base, which offers a value-added service oriented to enterprises.

research limitations: the technical innovation knowledge base only includes parts of amino acids technology knowledge, making it suitable to meet certain specific needs.

practical implications: semantic annotation of technical innovation knowledge from patents requires manual work by domain experts.

originality/value: the amino acids industry knowledge service platform offers not only an integrated search service for amino acids industry information, but also a deep tech mining service for technical innovation knowledge of amino acids. it will offer a more personalized knowledge service in the future.
