In this chapter, we cover the foundations of abstract syntax. This includes the notion of conformance of terms (trees) or models (graphs) to signatures or metamodels . The proposed notations for signatures and metamodels correspond to proper software languages in themselves, giving rise to a ...
图神经网络代码模型（GraphCodeBERT）GraphCodeBERT是在CodeBERT的基础上进一步改进的模型，它引入了图神经网络（Graph Neural Network，GNN）来更好地处理代码的结构信息。代码的语法和语义结构可以自然地表示为图结构，例如抽象语法树（Abstract Syntax Tree，AST）。GraphCodeBERT通过GNN对代码的图结构进行建模，能够更深入...
To discover the dependency graph between files, we can process theUntyped Abstract Syntax Tree(AST) to detect links. Because the information inside the AST isn’t as rich as the typed tree, we know that our resolution will be a super-set of the actual dependency graph. Using the typed tre...

接着执行词法语法分析方法,将规则有向无环图中各个节点的EPL转换为与其对应的AST(Abstract Syntax Tree,抽象语法树),再将AST翻译为任务java代码。最后调用maven命令打包java代码为任务jar包,并将任务jar包及基础运行库一并提交到Flink-on-YARN集群。 Flink有多种运行模式(例如 standalone Flink cluster、Flink cluster...

libFirm contains algorithms for construction of the SSA form directly from the attributed syntax tree. A set of analyses and optimization phases is provided. This version includes a complete backend for the IA32 and SPARC architecture, as well as unfinished backends for MIPS, ARM, and AMD64....
Syntax T = minspantree(G) T = minspantree(G,Name,Value) [T,pred] = minspantree(___)Description T = minspantree(G) returns the minimum spanning tree, T, for graph G. example T = minspantree(G,Name,Value) uses additional options specified by one or more Name-Value pair arguments...
Graph-theoretic methods, in various forms, have proven particularly useful in linguistics, since natural language often lends itself well to discrete structure. Traditionally, syntax and compositional semantics follow tree-based structures, whose expressive power lies in the principle of compositionality, ...
