Human game players rely heavily on the experience gained by playing over the games of masters. A player may recall a previous game to either obtain the best move (if he has previously seen the identical position) or suggest a best move (if similar to others seen). However, game-playing programs operate in isolation, relying on the combination of search and programmed knowledge to discover the b...

This paper describes a HMM-based chunk tagger and its extensions used in KRDL for the shared task of CoNLL'2000. Compared with standard HMM-based tagger, this tagger incorporates more contextual information into a lexical entry. Moreover, an error-driven learning approach is adopted to decrease the memory requirement. It keeps only positive lexical entries which contribute to the error reductio...

Abstract Bio-inspired optimization aims at adapting observed natural behavioral patterns and social phenomena towards efficiently solving complex problems, is nowadays gaining much attention. However, researchers recently highlighted an inconsistency between the need in field actual trend. Indeed, while it important to design innovative contributions, trend bio-inspired re-iterate existing know...

The rapidly expanding size of data makes it difficult to extricate information and store as computerized knowledge. Relation extraction term play a crucial role in resolving this issue. Automatically finding concealed relationship between terms that appear the text can help people build computer-based knowledge more quickly. Term is required one components because identifying significant essent...

Chunking is segmenting a text into chunks, sub-sentential segments, that Abney approximately defined as stress groups. Chunking usually uses monolingual resources, most often exhaustive, sometimes partial : function words and punctuations, which often mark beginnings and ends of chunks. But, to extend this method to other languages, monolingual resources have to be multiplied. We present a new ...

Just-In-Time Information Retrieval agents proactively retrieve information based on queries that are implicit in, and formulated from, the user’s current context, such as the blogpost she is writing. This paper compares five heuristics by which queries can be extracted from a user’s blogpost or other document. Four of the heuristics use shallow Natural Language Processing techniques, such as ta...

Movement sequences such as typing or tapping display important interactions among Wnger movements arising from anticipatory motion (preparing for upcoming events) and coupling (non-independence among Wngers). We examined pianists’ Wnger tapping for the inXuence of cognitive chunking processes and biomechanical coupling constraints. In a synchronization-continuation task, pianists repeatedly tap...

The study investigated the effects of chunking and perceptual patterns that guide the drawings of Rey complex figure. Ten adult participants (M age=22.2 yr., SD=4.1) reproduced a single stimulus in four drawing modes including delayed recall, tracing, copying, and immediate recall across 10 sessions producing a total of 400 trials. It was hypothesized that the effect of chunking is most obvious...

During language acquisition, children learn to segment speech into phonemes, syllables, morphemes, and words. We examine word segmentation specifically, and explore the possibility that children might have generalpurpose chunking mechanisms to perform word segmentation. The Voting Experts (VE) and Bootstrapped Voting Experts (BVE) algorithms serve as computational models of this chunking abilit...
