A common computational goal is to encapsulate the modeling of a target phenomenon within a unified and comprehensive ”engine”, which addresses a broad range of the required processing tasks. This goal is followed in common modeling of the morphological and syntactic levels of natural language, where most processing tasks are encapsulated within morphological analyzers and syntactic parsers. In ...

Determining and modeling phonological phenomena is necessary to generate speech from textual input. These phenomena include letter to sound conversion, syllabification, sound change, stress assignment and intonation assignment. This paper presents work on Urdu phonological processes and provides algorithms to convert textual input into phonologically annotated output, required for Urdu text-to-...

We predict stock markets using information contained in articles published on the Web. Mostly textual articles appearing in the leading and the most influential financial newspapers are taken as input. From those articles the daily closing values of major stock market indices in Asia, Europe and America are predicted. Textual statements contain not only the effect (e.g., stocks down) but also t...

This paper introduces iAutoMotion, an autonomous video retrieval system that requires only minimal user input. It is based on the video retrieval engine IMOTION. iAutoMotion uses a camera to capture the input for both visual and textual queries and performs query composition, retrieval, and result submission autonomously. For the visual tasks, it uses various visual features applied to the capt...

This paper introduces INblobs, a visual editor and interpreter for interaction nets that is presently being developed at Minho. The editor is based on Blobs, a front-end for drawing and editing graph diagrams written with wxHaskell. The tool fills a gap in the community, since all the existing tools for interaction nets take as input textual descriptions of nets. INblobs includes a visual edito...

We studied changes to the pattern of speech errors as a function of selectively attending to one word in a sequence to learn how attention is implemented in language production. Three hypotheses were tested: (1) attention specifically inhibits the past, (2) attention enhances the activation of the present without affecting the past or the future, and (3) attention decreases priming of the futur...

In this paper, a review of the role of input, output and instruction in second language acquisition is provided. Several pedagogical interventions in grammar instruction (e.g., processing instruction, input enhancement, structured output and collaborative output tasks) are presented and their effectiveness reviewed. A final and overall evaluation is provided at the end of the paper.
