In video database systems, one of the most important methods for discriminating the videos is by using the objects and the perception of spatial and temporal relations that exist between objects in the desired videos. In this paper, we propose a new spatio-temporal knowledge representation called 3D C-string. The knowledge structure of 3D C-string, extended from the 2D C-string, uses the projec...

The paper introduces a grammar formalism for defining the set of sentences in a language, a set of labeled trees (not the derivation trees of the grammar) for the representation of the interpretation of the sentences, and the (possibly non-projective) correspondence between subtrees of each tree and substrings of the related sentence. The grammar formalism is motivated by the linguistic approac...

We describe here a method for discovering imitative textual allusions in a large collection of Classical Latin poetry. In translating the logic of literary allusion into computational terms, we include not only traditional IR variables such as token similarity and ngrams, but also incorporate a comparison of syntactic structure as well. This provides a more robust search method for Classical la...

1.1 Silenus Silenus (Mi et al., 2008; Mi and Huang, 2008) is a forest-based tree-to-string SMT system. A packed parse forest is a compact representation of all derivations (i.e., parse trees) for a given sentence under a context-free grammar. A tree-to-string rule describes the correspondence between a source parse tree and a target string. Unlike previous tree-to-string (Liu et al., 2006; Huan...
