Language is a complex but fundamental human skill, the goal of which is communication among individuals. To fulfill this goal, speakers and listeners have to perform a number of distinct tasks, among them associating words with their meanings (semantics), and conveying or inferring sense from the relationships among words in the sentence (syntax). Recent studies, using imaging techniques to ide...

Much progress has been made in the past two decades, and increasingly since the popularizing of the Internet and the advent of the Web, in exploiting new technologies in support of the dissemination of geographic information. Data warehouses, spatial data libraries, and geoportals have proliferated, and today’s users of geographic information have a wealth of potential sources that can be searc...

Two groups of children who were slow in expressive language development (SELD) at age 2 and a matched group of toddlers with normal language were re-evaluated at age 4. Assessment included measures of productive syntactic skills in spontaneous speech and narrative abilities in a standard story retelling task. Four-year-olds who continued to perform below the normal range in sentence structure p...

Study of patterns on images is recognized as an important step in characterization and classification of image. The ability to efficiently analyze and describe image patterns is thus of fundamental importance. The study of syntactic methods of describing pictures has been of interest for researchers. Array Grammars can be used to represent and recognize connected patterns. In any image the patt...

A formalism for ~he representation of "semantic emphases" is introduced, using principal and accessory instantiatiQns. It m~es it possible to convert predicate expressions inbo network-like structures. As an application criteria for ooligatory and optional actants are dealt with. 11 ~ 12, t I ~ t2, t I starts t2, t I finishes t 2 etco (Allen (1984); Bier-winch (1988) for the general framework)....

In this work a proposal for automatic textual segmentation is described. The proposal uses the output of an automatic syntactic analyzer – Parser Palavras – to create textual segmentation. Parse trees are used to infer text segments and a dependency tree of the identified segments. The main contribution of this work is the use of the syntactic structure as source for the automatic segmentation ...

Computational thinking has been identified as an essential 21st century skill. Unfortunately, many computer users, particularly children, consider programming to be hard and boring. There are two fundamental barriers to making programming more appealing: cognitive challenges to overcoming the hard part, and affective challenges to overcoming the boring part. AgentCubes is a new 3D creativity to...

In this paper, we employ the centering theory in pronoun resolution from the semantic perspective. First, diverse semantic role features with regard to different predicates in a sentence are explored. Moreover, given a pronominal anaphor, its relative ranking among all the pronouns in a sentence, according to relevant semantic role information and its surface position, is incorporated. In parti...
