Natural Language Processing for learners of foreign languages: some problems and suggested solutions.

Abstract:
When someone is learning a foreign language, a great amount of high quality language input is needed. This is especially true when discovery learning is encouraged. When students can discover for themselves some elements of how language works, much deeper processing is taking place. This in turn has long-term benefits due to a more conceptual grasp of the language that has been derived from the language being studied rather than through mere surface translations. Non-native speakers do not have the luxury of time to be exposed to a great amount of high quality input, on which they might otherwise test language hypotheses. When students have a large amount of high quality language in a database through which they can isolate specific language items, they can observe, hypothesize and test their findings. And this is what Data Driven Learning is - a pedagogical application of NLP. I am currently working on a small program that can present lines of text in order of the sum of the items in each example. The result should be a screen of text, with the target item centered and its context presented in order of familiarity of vocabulary items. For research purposes, this concordancer is all but ready. It remains to find out if the hypothesis that providing students with contexts is likely to understand contributes to the intended pedagogical gain.

IA-64 (Intel Architecture 64 bit)

Abstract:
Intel and Hewlitt-Packard teamed up to create a new 64-bit architecture that is the successor of the RISC and CISC architectures. They called it EPIC (Explicitly Parallel Instruction Computing). This architecture could serve as a platform for creating a processor that can run in parallel, with more simplified hardware requirements (more than CISC) to include more advanced drives to achieve better performance. Compared to the previous Intel processor, they will contain a large amount of registry. Zaroven should maintain consistency with IA-32, both hardware and PA-RISC software.
The lecturer discusses the main ideas behind this architecture.

Corpus-oriented speech synthesis

Abstract:
Traditional speech synthesis in the time domain uses (relatively) a small number of usually phonetically motivated units (allophytes, dipony, syllables) from which the collection is traced back. In the synthesis, however, the segments are deformed as a result of prosodic modifications, which degrades the quality of the resulting speech. Therefore, more modern approaches make use of a greater number of heterogeneous segments (ranging from 10 ^ to 10 ^ 6). With such a record database, the need for prosodic modifications to the background subsides, but it is an interesting problem to select units that are in some sense optimal.

Enhancing Czech WordNet

Abstract
After explaining how WordNet and its follower EuroWordNet are and how they came about, I would like to focus on the current state of the EuroWord Net at our faculty and look at its expansion. To do this, I will use the experience I have gained in a specific work on spreading a cluster of lexical data and setting up the problems associated with this work.

Theory Refinement in Active Learning: An Application in Morphological Disambiguation of Czech "

Abstract:
Our work stands in the border between machine learning and natural language processing. We employ inductive logic programming to induce a set of rules for a morphological disambiguation of Czech. In this task, it is expensive to collect a sufficient amount of labelled examples needed for training. On the other hand, unlabelled texts are freely available. The objective of active learning is to select those examples that will be most informative for the learner. Since this example selection proceeds step-by-step, it is possible to refine the actual theory in order to disambiguate the new selected examples correctly. Thus, we aim at a combination of techniques: theory refinement within active learning. The outline of our approach and some experimental results will be presented.

Design of tools for universal cognitive modeling

Abstract:
The concept of the Tonal tool for universal cognitive modeling, on whose design and implementation I work, will be presented. The introduction briefly mentions the issue of finding a suitable conceptual device for cognitive modeling.
Next, the theoretical background of the Tonal instrument concept. I will divorce the context with the natural language semantics and Transparent Intentional Logic (TIL). Describe the modeling entity of the Tonal tool and on the examples I will illustrate their use. We mention the possibility of using the model of access to the field of artificial intelligence (machine learning, data mining, neuron site, genetic algorithms).
The general description of the dynamics of cognitive models is based on the model of the transfer of attention in the model.
On top of that, I will introduce the role of Tonal as a workbench for research in the field of cognitive science and its use in computer science, which is forced by a brother to research the "cognitive element" in thought.

Morfematically analyze the casein

Abstract:
The aim of the lecture is to present ideas for the design and implementation of a morphematic analyzer based on a combination of form-forming and word-formation analysis. As the shape-forming analysis has already been algorithmically described, one step is to smooth the morphematic analysis, namely algorithmization of the word-word analysis. The result of the morphematic analysis is to determine the structure of the analyzed word and the identification of the individual morphs. The aim is to find a suitable representation of the morphus and to evaluate the possibilities of automatic processing of selected derivation processes. The application of the morphemic analyzer on the corpus of Czech texts will then yield usable statistical data reflecting the current state of the cousin.

Introduction to system verification (model checking)

Abstract
The lecture deals with the support of decision-making and management processes and information flows using university information systems (UIS - University Information System) in connection with the development of computer networks and possibilities of remote work with data. This in turn leads to changes in the sets of typical users of each application, and to a significant increase in the number of new users, in the case of the University of Teachers and students. When deploying the information system, one of the important input decisions is the degree of involvement of affected persons in direct work with the system.

Multimedia Data Indexing

Abstract:
Recently, the need to manage various types of data stored in large computer repositories has drastically increased and resulted in the development of multimedia database systems with the goal of uniformly managing voice, video, image, text and numerical data. Among the many research challenges that multimedia technology involves - including content placement, presentation, synchronization, ... - content-based retrieval plays a dominant role. In particular, there is an urgent need for indexing techniques that can support the execution of similarity queries. This paper presents some basic index structures.

Dialogue Interface Generator

Abstract
The dialog interface seems to be an appropriate solution for communicating the user with the computer. This solution will allow the number of potential users of computer systems to be captured by people who do not know what to do with these systems. One of the dialog entry standard used in the dialog interfaces is VoiceXML. Due to the large number of existing applications whose user interface is based on HTML, the idea was to automatically generate dialogs for the above mentioned applications. In the lecture, lectures will be introduced to the basic principles of dialog generation. Further, the problematic points of this approach will be discussed, along with the suggestion of possible solutions.

Registration of images taken with an axial tomograph

Abstract
The Optical Microscopy Laboratory (LOM) has an interesting device available at the patented University of Heidelberg, which allows observing objects under a microscope (a cell) from a multi angle - axial tomograph. The cells are attached to the fibers that can be rotated. The axial resolution of the microscope is always superior to lateral resolution. Compositions of several images can be improved. A major step towards improving resolution is the good recording of the image (ie, the relative picture of the image so that the observed objects are as close as possible). During the lecture will be introduced an effective algorithm for the registration of the point set points developed in LOM, which is suitable for this purpose.

Reading mathematical expressions to the blind

Abstract
Visually impaired students currently have the opportunity to acquire knowledge faster and to a greater extent thanks to the development of computer technology and information technology. However, for the study of graphic objects, they still need the assistance of a visible worker who adjusts materials to the appropriate form. This category also includes the study of mathematical texts. The lecture will provide a brief overview of how math texts can be passed on to blind people. We will focus on different ways of reading or editing mathematical expressions. Furthermore, students will be introduced to the design of a multimodal way of reading mathematical expressions and using a dialog for their editing. In this context, the MathML markup language will be mentioned. At the end of the lecture will be demonstrated the prototype system for the study of mathematical expressions by the blind.

Pattern recognition in computer typography

Abstract
We describe the pattern technique as a means of obtaining and recognizing information in the data, and using the word-cutting patterns in the slot machine at the same time. We have developed the PatLib library for general pattern manipulation, and we intend to use it more widely for recognizing various phenomena in quote material, such as sentence boundaries, segmentation, compound word seams. We will describe the architecture of the library. Next, we formulate the idea of ​​the Pattern Translation Process, a pattern-recognition machine, on a stream of expanded rate material. We discuss the benefits that PTP would bring over "traditional" techniques (such as Omega Translation Processes).

Reconstruction of round objects using simplex networks

Abstract
The lecture will address the problem of how to determine and represent the surface of an unknown real object based on the set of input points measured on its surface. An overview of the methods that are used to resolve this issue will be provided. Since we observe mainly round objects (cell nuclei) in the optical microscopy laboratory, we will focus on the discussion of individual methods towards usability in our application. Deeper development of the method based on deformation of the simplex network, which is suitable for the reconstruction of round objects, will be introduced.
