A novel extreme learning fault diagnosis based supervision applied to mathematical formula contrastive analysis

Focusing on the issue of few contrastive analysis technologies existing on mathematical formula in literatures, two methods of mathematical formula contrastive analysis subject to PDF and XML document formats are proposed. First, a novel extreme learning machine (ELM) fault diagnosis based supervision is presented and applied to mathematical formula contrastive analysis subject to PDF document. The strategy employs its merits such as fast learning speed, ease of implementation high efficiency and minimal human intervention, and not rely on the hidden neurons tuned. At the same time, the supervision mechanism is combined to realize the novel mathematical formula contrastive analysis based ELM supervision (ELMS). Second, a new mathematical formula contrastive analysis based MathML subject to XML document formats is presented. The idea first recognizes and extracts mathematical formulas in the detected XML document, normalizing the markup code of mathematical formulas. And then creating the tree presentation of mathematical the formula according to its presentation markup code, normalizing the tree structure by rule base, level traversing the tree to normalize the variable names and to get structure code of the tree. At last, searching the formula information table that named by the structure code. If the table exist, then searching the preorder traversal sequence of the tree in the table. If the records exist, then searching the postorder traversal sequence of the tree in the records. The searching result confirm if the mathematical formula belong to plagiarism. The experimental results reveal that the proposed algorithms can complete the contrastive analysis accurately of mathematical formula in XML documents whatever it existings PDF or XML format and has high performance on detection accuracy and speed.

Towards semantic mathematical editing

Currently, there exists a big gap between formal computer-understandable mathematics and informal mathematics, as written by humans. When looking more closely, there are two important subproblems: making documents written by humans at least syntactically understandable for computers, and the formal verification of the actual mathematics in the documents. In this paper, we will focus on the first problem.For the time being, most authors use ▪, ▪, or one of its graphical front-ends in order to write documents with many mathematical formulas. In the past decade, we have developed an alternative wysiwyg system GNU ▪, which is not based on ▪. All these systems are only adequate for visual typesetting and do not carry much semantics. Stated in the MathML jargon, they concentrate on presentation markup, not content markup.In recent versions of ▪, we have started to integrate facilities for the semantic editing of formulas. In this paper, we will describe these facilities and expand on the underlying motivation and design choices.To go short, we continue to allow the user to enter formulas in a visually oriented way. In the background, we continuously run a packrat parser, which attempts to convert (potentially incomplete) formulas into content markup. As long as all formulas remain sufficiently correct, the editor can then operate both on a visual or semantic level, independently of the low-level representation being used.An important related topic, which will also be discussed at length, is the automatic correction of syntax errors in existing mathematical documents. In particular, the syntax corrector that we have implemented enables us to upgrade existing documents and test our parsing grammar on various books and papers from different sources. We will provide a detailed analysis of these experiments.

MPML3D: Scripting Agents for the 3D Internet

The aim of this paper is two-fold. First, it describes a scripting language for specifying communicative behavior and interaction of computer-controlled agents ("bots") in the popular three-dimensional (3D) multiuser online world of "Second Life" and the emerging "OpenSimulator" project. While tools for designing avatars and in-world objects in Second Life exist, technology for nonprogrammer content creators of scenarios involving scripted agents is currently missing. Therefore, we have implemented new client software that controls bots based on the Multimodal Presentation Markup Language 3D (MPML3D), a highly expressive XML-based scripting language for controlling the verbal and nonverbal behavior of interacting animated agents. Second, the paper compares Second Life and OpenSimulator platforms and discusses the merits and limitations of each from the perspective of agent control. Here, we also conducted a small study that compares the network performance of both platforms.

Converting Saint Paul: A new TEI P5 edition of The Conversion of Saint Paul using stand-off methodology

This article reports on the details behind a poster presented a the Text Encoding Initiative (TEI) Members' Meeting at the University of Maryland, College Park, in November 2007. It looks at the creation of of af scholarly electronic edition of a late-medieval play, The Conversion of Saint Paul from Bodleian MS Digby 133 using TEI P5 XML. In addition to exploring various new features available in the TEI P5 Guidelines, it also examines the methodology used to create the text, up-scaling from purely presentation markup to descriptive markup, and how this might simplify the creation of such editions. In an attempt to create an interoperable, flexible, and agile edition, it stores anything not directly related to the transcription of the text in separate files in a stand-off manner. In an attempt to experiment with creating a resource which leverages the advantages of networked editions, it documents the attempt to interoperate with the Middle English Dictionary. Although this first appears to be a failure, it highlights some of the inherent problems in attempting to build editions that are dependent on the resources of others. The article concludes with an urge to text encoders to make more of an effort to share examples of, both good and bad, community practice.

AUTOMATIC GENERATION OF GAZE AND GESTURES FOR DIALOGUES BETWEEN EMBODIED CONVERSATIONAL AGENTS

In this paper we introduce a system that automatically adds different types of non-verbal behavior to a given dialogue script between two virtual embodied agents. It allows us to transform a dialogue in text format into an agent behavior script enriched by eye gaze and conversational gesture behavior. The agents' gaze behavior is informed by theories of human face-to-face gaze behavior. Gestures are generated based on the analysis of linguistic and contextual information of the input text. The resulting annotated dialogue script is then transformed into the Multimodal Presentation Markup Language for 3D agents (MPML3D), which controls the multi-modal behavior of animated life-like agents, including facial and body animation and synthetic speech. Using our system makes it very easy to add appropriate non-verbal behavior to a given dialogue text, a task that would otherwise be very cumbersome and time consuming. In order to test the quality of gaze generation, we conducted an empirical study. The results showed that by using our system, the naturalness of the agents' behavior was not increased when compared to randomly selected gaze behavior, but the quality of the communication between the two agents was perceived as significantly enhanced.

DEVELOPMENT OF MULTIMODAL PRESENTATION MARKUP LANGUAGE MPML-HR FOR HUMANOID ROBOTS AND ITS PSYCHOLOGICAL EVALUATION

Animated agents that act and speak as attendants to guests on shopping web sites are becoming increasingly popular. Inspired by this development, we propose a new method of presentation using a humanoid robot. Humanoid presentations are effective in a real environment because they can move and look around at the audience similar to a human presenter. We developed a simple script language for multimodal presentations by a humanoid robot called MPML-HR, which is a descendant of the Multimodal Presentation Markup Language (MPML) originally developed for animated agents. MPML-HR allows many non-specialists to easily write multimodal presentations for a humanoid robot. We further evaluated humanoid robots' presentation ability using MPML-HR to find the difference in audience impressions between the humanoid robot and the animated agent. Psychological evaluation was conducted to compare the impressions of a humanoid robot's presentation with an animated agent's presentation. Using the Semantic Differential (SD) method and direct questioning, we measured the difference in audience impressions between an animated agent and a humanoid robot.

MPML: a markup language for controlling the behavior of life-like characters

Animated agents have the potential to convey information in a more natural way than other media traditionally used on the world-wide web, such as text, audio, or video clips. They also allow for more natural styles of human–computer interaction than navigation through hypertext documents. In this paper, we will introduce the multi-modal presentation markup language (MPML), which is a powerful and easy-to-use XML-style language enabling content authors to script rich web-based interaction scenarios featuring life-like characters. MPML is a powerful language as it provides controls for the verbal and non-verbal behavior of affective 2D cartoon-style characters, presentation flow, and the integration of external objects, like Java applets. MPML is easy-to-use since we also offer a graphical scripting environment (a visual editor) that facilitates the creation of complex presentation scripts. We will describe the tagging structures of MPML, the MPML3.0 Visual Editor, and illustrate the usefulness of the tagging structures of the language by the actual implementation of a web-based casino where the user may interact with life-like characters.
