We present a case study of the use of Dynamic Condition Response (DCR) Graphs, a recently introduced declarative business process model, in the design of a cross-organizational case management system being developed by Exformatics A/S, a Danish provider of knowledge and workflow management systems. We show how DCR Graphs allow to capture directly both the behavioral constraints identified during meetings...
This paper describes how natural language processing and ontologies are exploited for automatic text categorisation. The approach introduced is part of the MANENT system, an infrastructure for integrating, structuring and searching Digital Libraries. The procedure of structural information extraction, and of the automatic classification of the records according to natural language understanding and...
This paper presents a meaning-based method to distinguish text without or with little semantic content from text that has meaning which can be processed. The basic method assumes that a semantic analyzer will be able to produce less output from semantically less grammatical input text. The method was pilot-tested on a corpus of blog spam. Future improvements, including a method to distinguish semantically...
It is a challenge to identify the relevant pieces for further intelligence analysis among a big chunk of data. Filters have been built to provide such a function in almost all the network traffic capture and analysis tools as well as signature-based intrusion detection systems. However, most filters only work on strings of words, numbers, and/or other symbols. This paper proposes a type of context-aware...
A novice user is generally required to pass the Human Interactive Proof(HIP) before they are allowed to register web services, since there are so many automated software tools and automated scripts available in public web services. Thus there are many variations to help HIP. Text-based CAPTCHA is the most common method, where each user is asked to discern the hidden characters in noisy-images. Many...
Based on the former studies of transferred epithet and Fauconnier and Turner's conceptual integration theory, this paper adopts a cognitive semantic approach to the in-depth analysis of the on-line meaning construction of transferred epithet. This study explores the meaning construction of transferred epithet from a new perspective. It can help the language learners have a better understanding of...
State-of-the-art supervised approaches for automatically detecting disease reporting events are typically constructed using manual training examples. Such systems suffer from high initial, and sustainability costs.
Recent research has been focused on the creation of intelligent compositional systems that utilize ontologies as a knowledge base to facilitate the composition of new systems/workflows. Within this “ontology-driven” compositional systems field, experts have created knowledge representation models to satisfy requirements of their own domain rather than considering a general perspective. This paper...
In order to apply the web crawler's technology to the construction of video semantic information, this paper propose the video information collection architecture based on Web crawler after has analyzed the basic principles, key technologies and problems of the current crawler technology. The system framework divided to two parts. The background part mainly manage Web crawler; Foreground part mainly...
This study examined the feasibility of decoding semantic information from human cortical activity. Four human subjects undergoing presurgical brain mapping and seizure foci localization participated in this study. Electrocorticographic (ECoG) signals were recorded while the subjects performed simple language tasks involving semantic information processing, such as a picture naming task where subjects...
Affective lexicons are a useful tool for emotion studies as well as for opinion mining and sentiment analysis. Such lexicons contain lists of words annotated with their emotional assessments. There exist a number of affective lexicons for English, Spanish, German and other languages. However, only a few of such resources are available for French. A lot of human efforts are needed to build and extend...
This paper presents a new edge-counting based method using Word Net to compute the similarity. The method achieves a similarity that perfectly fits with human rating and effectively simulate the human tHought process that is people prefer to consider more differences when the semantic distance between two word is closer, and vice versa. At last, we weigh up our model against a benchmark set by human...
Epistemic relativism is the term used to denote the fact that knowledge established in a society (or part of a society) is specific to that society (or part of the society) and, thus, possibly different from knowledge established in any other society (or part of the society). Epistemic relativism results from the fact that knowledge is socially constructed, in a historically conditioned way. This...
This paper presents a tool for automatic generation of ANSI C code from models expressed in IOPT (Input-Output Place-Transition) Petri Nets. The inputs of the tool are PNML (Petri Nets Mark-up Language) files containing the IOPT Petri net models. The tool has two different interfaces: one relying on a simple graphical interface (amenable to be used by humans), and a second one with a command line...
The most common approach in Cross Language Question Answering (CLQA) is to employ question translation. The easiest way to conduct question translation is by translating the source question into target language using existing machine translation or bilingual dictionary. However, the error resulted by the question translation may influence the accuracy of CLQA. This research proposes an adaptation...
Thanks to ICT, Web emergency and Internet, the achievement of maintenance services and monitoring can be performed automatically, remotely and through various distributed information systems. Hence the emergence of the concept of services offered through maintenance architectures, ranging from autonomic systems to integrated systems where knowledge management, cooperation and collaboration are vital...
Humans create efficient social structures in a self-organized way based on a feature called homophily. This paper proposes the use of homophily in Service-Oriented Multiagent Systems to create efficient self-organized structures and provide a decentralized service management.
A stylistic device frequently employed by filmmakers is the synchronous montage (composition) of audio and visual elements. Synchronous montage helps to increase tension and tempo in a scene and highlights important events in the story. Sequences with synchronous montage usually contain rich semantics which is relevant for understanding a movie. This property is currently not exploited in automated...
We present two social tagging games based on the Chain Model for object association. GiveALink Slider and Great Minds Think Alike harness human power to generate large streams of social tagging data. Such social annotations are utilized to help people organize Web resources and infer semantic relationship, which in turn can enhance Web applications such as search, recommendation, navigation, and categorization...
Electronic negotiations are business negotiations conducted via electronic means using information and communications technologies (ICT). Two dominant types of electronic negotiation systems are automated negotiation systems for software agents and negotiation support systems (NSSs) for humans. However, the integration of two types for human-agent negotiations is an important task. In this paper,...
