We describe how to extend the ACT-R production system to model human errors in the performance of a high-level cognitive task: to solve simple linear algebra problems while memorizing a digit span. Errors of omission are produced by introducing a cutoff on the latency of memory retrievals. If a memory chunk cannot gather enough activation to be retrieved before the threshold i s reached, retrie...

In language communication, an utterance may be segmented as a concatenation of chunks that are reasonable in syntax, meaningful in semantics, and composed of several words. Usually, the order of words within chunks is fixed, and the order of chunks within an utterance is rather flexible. The improvement of spoken language translation could benefit from using bilingual chunks. This paper present...

Definition A chunk is meaningful unit of information built from smaller pieces of information, and chunking is the process of creating a new chunk. Thus, a chunk can be seen as a collection of elements that have strong associations with one another, but weak associations with elements belonging to other chunks. Chunks, which can be of different sizes, are used by memory systems and more general...

In this paper we explore two strategies to incorporate local morphosyntactic features in Hindi dependency parsing. These features are obtained using a shallow parser. We first explore which information provided by the shallow parser is most beneficial and show that local morphosyntactic features in the form of chunk type, head/non-head information, chunk boundary information, distance to the en...

With the fast development of mobile communication technologies and increased capabilities of smart terminals, the multimedia service has become one of the most attractive applications in mobile Internet. And the combination of socialbased mobile multimedia and mobile peer-to-peer (P2P) network has attracted increasing research interests in recent years. However, how to deploy large scale P2P-ba...

The problem of chunk-based resource allocation for the uplink of Long Term Evolution is investigated. In this paper, a combined order using the promethee method and analytic hierarchy decision for chunk allocation algorithm is proposed. The utility of each order is sorted based on promethee method approach so that the utility of each order could be approximated as the average of all criteria on...

Inspired by previous chunk-level reordering approaches to statistical machine translation, this paper presents two methods to improve the reordering at the chunk level. By introducing a new lattice weighting factor and by reordering the training source data, an improvement is reported on TER and BLEU. Compared to the previous chunklevel reordering approach, the BLEU score improves 1.4% absolute...

Distributed live streaming has brought a lot of interest in the past few years. In the homogeneous case (all nodes having the same capacity), many algorithms have been proposed, which have been proven almost optimal or optimal. On the other hand, the performance of heterogeneous systems is not completely understood yet. In this paper, we investigate the impact of heterogeneity on the achievable...

In this paper, the automatic labeling of semantic roles in a sentence is considered as a chunking task. We define a semantic chunk as the sequence of words that fills a semantic role defined in a semantic frame. It is straightforward to convert chunking into a tagging task using one of several IOB representations. Using this representation each word is tagged with I, which means that the word i...

Outlier detection in data streams has gained wide importance presently due to the increasing cases of fraud in various applications of data streams .The techniques for outlier detection have been divided into either statistics based , distance based , density based or deviation based. Till now, most of the work in the field of fraud detection was distance based but it is incompetent from comput...
