A fundamental step in sentence comprehension involves assigning semantic roles to sentence constituents. To accomplish this, the listener must parse the sentence, find constituents that are candidate arguments, and assign semantic roles to those constituents. Each step depends on prior lexical and syntactic knowledge. Where do children begin in solving this problem when learning their first lan...

An interesting question surrounding semisupervised learning for NLP is: should we use discriminative models or generative models? Despite the fact that generative models have been frequently employed in a semi-supervised setting since the early days of the statistical revolution in NLP, we advocate the use of discriminative models. The ability of discriminative models to handle complex, high-di...

Conceptual modelling methods such as ER (Chen, 1976), EER (Elmasri and Navathe, 1994; Gogolla, 1994), KISS (Kristen, 1994), NIAM (Nijssen and Halpin, 1989), OOSA (Embley, Kurtz, and Woodfield, 1992) and ORM (Halpin, 2001) have traditionally been developed with the aim of providing conceptual models of database structures. More recently, however, such modelling methods have shown their use for m...

Support for generalization hierarchies is widely recognized as a desirable feature of data models. While such hierarchies are indeed supported by data models such as NIAM and object oriënted models, the relational model is still deficiënt in this respect. Proposed enhancements suggested by Smith and Smith in their SHM model and by Codd in his RM/T model have not been included in Codd's new vers...
