Abstract: The disclosure generally relates to code recommendation. In one embodiment, code snippets may be extracted using an invocation-centered code slicing process and then grouped according to the method usages. For each method usage, a representative code snippet may be selected and stored in the knowledge base in association with metadata. In operation, the programming context may be obtained and used to query the knowledge base to retrieve one or more code snippets for recommendation. In one embodiment, the recommended code snippets may be ranked to improve the utility and user friendliness, and the metadata may be used to provide variation points and possibly other auxiliary information to improve the operation efficiency and user experience.

Abstract: The present invention discloses a soluble or dispersible long-acting mold-proof polyisocyanate or modified polyurethane, and the mold-proof materials made thereof, wherein an amino group (NH)-containing mold-proof agent (benzimidazol or a derivative thereof) becomes a portion of a PU structure in a urethane or urea reaction; thus, the mold-proof material has the superior compatibility and solubility and can be solved or dispersed in various solvents. Further, the polyisocyanate reacts with a saline and a polyol both having reactive functional groups to implement the adhesion between the mold-proof material and the substrate; thus, the mold-proof material can be applied to an inorganic material, such as a metal or a glass. Therefore, the mold-proof material and the derivatives thereof of the present invention have a superior dispersibility/solubility and a long-acting mold-proof effect.
