Intermediate representations

xThe paper studies an automatic translation method that translates from the text of a language (L1) to the speech of an unwritten language (L2). Normally the written text is used as the bridge to connect a translation module that translates from the text of L1 to the text of L2 and a synthesis module that generates the speech of L2 from the text.

Web-based instructional software offers new opportunities for collaborative, task-oriented in-service training. Planning and negotiation of content to adapt a web-based learning resource for nursing is the topic of this paper. We draw from Cultural Historical Activity Theory to elaborate the dialectical relationship of changing and stabilizing organizational practice. Local adaptation to create a domain-specific resource plays out as interactions of orientations and instrumentalities. Our analysis traces how orientations, i.e.

Interpreted computer programs — in a batch or interactive session — are either decoded and then immediately executed or are decoded into some efficient intermediate representation for future execution. BASIC, Perl, and Python are examples of immediately executed computer programs. Alternatively, Java computer programs are compiled ahead of time and stored as a machine independent code called bytecode. Bytecode is then executed on request by an interpreter called a virtual machine.

This paper reports a research effort in Information Extraction, especially in template pattern matching. Our approach uses reach domain knowledge in the football (soccer) area and logical form representation for necessary inferences of facts and templates filling. Our system FRET' (Football Reports Extraction Templates) is compatible to the language-engineering environment GATE and handles its internal representations and some intermediate analysis results.

This paper describes a 'Logical Form' target language for representing the literal meaning of English sentences, and an intermediate level of representation ('Quasi Logical Form') which engenders a natural separation between the compositional semantics and the processes of scoping and reference resolution. The approach has been implemented in the SRI Core Language Engine which handles the English constructions discussed in the paper.

This paper proposes a method for organizing linguistic knowledge in both systematic and flexible fashion. We introduce a purely applicative language (PAL) as an intermediate representation and an object-oriented computation mechanism for its interpretation. PAL enables the establishment of a principled and well-constrained method of interaction among lexicon-oriented linguistic modules. The object-oriented computation mechanism provides a flexible means of abstracting modules and sharing common knowledge. ...

1.2 Canonical Level This intermediate level of representation usually consists of the verb itself, (or perhaps a more primitive semantic predicate chosen to represent the verb) and a list of possible roles, e.g. arguments to the predicate. These roles correspond loosely to a union of the various semantic types indicated in the schemas. The schemas above could all easily map i n t o : SUPPORTS(l,2, ,).

This paper deals with the automatic translation of route descriptions into graphic sketches. We discuss some general problems implied by such inter-mode transcription. We propose a model for an automatic text-to-image translator with a two-stage intermediate representation in which the linguistic representation of a route description precedes the creation of its conceptual representation.

The interpretation of temporal expressions in text is an important constituent task for many practical natural language processing tasks, including question-answering, information extraction and text summarisation. Although temporal expressions have long been studied in the research literature, it is only more recently, with the impetus provided by exercises like the ACE Program, that attention has been directed to broad-coverage, implemented systems. In this paper, we describe our approach to intermediate semantic representations in the interpretation of temporal expressions. ...

We present a probabilistic model extension to the Tesni` re Dependency Structure e (TDS) framework formulated in (Sangati and Mazza, 2009). This representation incorporates aspects from both constituency and dependency theory. In addition, it makes use of junction structures to handle coordination constructions. We test our model on parsing the English Penn WSJ treebank using a re-ranking framework.

Operations in the intermediate stage segregate some elements and group others, forming coherent representations. In late visual process- ing stages certain regions of the object are selected for further scrutiny, memories are activated, objects are recognized and associated with meanings. In the case of visual stimuli found to be aesthetically pleasing, these operations elicit emo- tional processes, which feedback into the system via attentional mechanisms.

Epigenetic mechanisms, such as histone modifications, control eukaryotic development beyond DNA-stored information. Intrigu-ingly, there is an under-representation of repressive marks in quies-cent (resting) cells, stem cells and regenerating cells, but a selective accumulation of aberrant histone lysine methylation profiles in aging, ‘‘stressed’’ and tumor cells, particularly for the H3K9, H3K27 and H4K20 methyl marks.

This textbook introduces sparse and redundant representations with a focus on applications in signal and image processing. The theoretical and numerical foundations are tackled before the applications are discussed. Mathematical modeling for signal sources is discussed along with how to use the proper model for tasks such as denoising, restoration, separation, interpolation and extrapolation, compression, sampling, analysis and synthesis, detection, recognition, and more. The presentation is elegant and engaging.
