... heterogeneous graph with nodes V and edges E, and G = (V,E) = (V M ∪V U ,E M ∪ E U ∪ E MU ). G is divided into three subgraphs, G M , G U and G MU . G M = (V M ,E M ) is a weighted undirected graph representing ... data for training and the rest for testing. Before building the graphs (i.e., the tweet graph, the author graph, and the tweet-author graph) , the dataset was preprocesse...

... restricted to acyclic graphs that have at most one head per node. Dependency graphs satisfying these constraints are called de- pendency forests. Definition 1 A dependency graph G is said to be a ... sentence will be an undirected graph where each edge has a label with an annotation indicating whether the recon- struction process should prefer to link the pair of nodes with a leftward...

... this paper is on function words, a class of words with little intrinsic meaning but is vital in expressing grammatical relationships among words within a sentence. Such encoded grammatical infor- mation, ... reordering. This simple model works well when properly coupled with a well-trained language 712 model, but is otherwise impoverished without any lexical evidence to characterize the r...

... standard operation for working with such graphs is unification. The unification operation succedes only on a pair of compatible graphs, and its result is a graph containing the information ... semantic information in the form of directed graphs where attributes correspond to vectors and values to nodes. There is a simple correspondence between such graphs and the matrix notation lin...

... a pattern with which to expand it and then filling out that pattern with words drawn from a unigram distribution. This kind of coupled generative process can be naturally formalized with tree ... gen- erate MR and NL associated with MR rules m -v (top). Transducer rule 2 selects MR rule r from the MR gram- mar. Rule 3 simultaneously writes the MR associated with rule m and chooses an...
