    An important factor for discriminating between Web pages is their genre (e.g., blogs, personal homepages, e-shops, online newspapers, etc). Web page genre identification has a great potential in information retrieval since users of search engines can combine genre-based and traditional topic-based queries to improve the quality of the results. So far, various features have been proposed to quantif... View full abstract»

  • Document Length Normalization by Statistical Regression

    Publication Year: 2007, Page(s):11 - 18
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (432 KB) | HTML iconHTML

    The document-length normalization problem has been widely studied in the field of information retrieval. The cosine normalization (Baeza-Yates and Ribeiro-Neto, 1999), the maximum if normalization (Allan et al., 1997) and the byte length normalization (Robertson et al., 1992) are the most commonly used normalization techniques. In (Singhal et al., 1996), authors studied the retrieval probability o... View full abstract»

    The WindowDiff evaluation measure (Pevzner and Hearst, 2002) is becoming the standard criterion for evaluating text segmentation methods. Nevertheless, this metric is really not fair with regard to the characteristics of the methods and the results that it provides on different kinds of corpus are difficult to compare. Therefore, we first attempt to improve this measure according to the risks take... View full abstract»

    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (470 KB) | HTML iconHTML

    We present a music information retrieval approach based on power laws. Research in cognitive science and neuroscience reveals connections between power laws, human cognition, and human physiology. Empirical studies also demonstrate connections between power laws and human aesthetics. We utilize 250+ power-law metrics to extract statistical proportions of music-theoretic and other attributes of mus... View full abstract»

    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (530 KB) | HTML iconHTML

    The integration of semantic representation and retrieval technologies into mainstream Web applications depends on the ease of adoption and re-use of existing information and meta-data. While for textual information, analysis of the text content is quite standardized, for multimedia resources many archives and repositories resorted do define different metadata representations, creating obstacles to...

    The amount and heterogeneity of data in biomedical research, notably in interdisciplinary fields, requires new methods for the collection, presentation and analysis of information. Important data from laboratory experiments as well as patient trials are available but come out of distributed resources. The Charite - University Hospital Berlin has established together with the German Research Founda... View full abstract»

    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (332 KB) | HTML iconHTML

    In this paper, we evaluated the efficacy of mined association rules between words for measuring the similarity between documents to enhance the text retrieval. In our experiments, for each document relevant to a query, we formed a group of documents having at least one common frequent set of words with the answer document. Then we measured the precision of the documents in the same group as an ans... View full abstract»

    The present paper describes a Bayesian network approach to information retrieval (IR) from natural language texts in Greek. The network structure provides an intuitive representation of uncertainty relationships and the embedded conditional probability table is used by inference algorithms in an attempt to identify documents that are relevant to the user's needs, expressed in the form of Boolean q...

    This research project is headed for designing a rational believable agent with a goal based rational- emotional architecture which has to interact with humans in communicative scenarios by facial expressions. The proposed model defines interactions among rationality, personality and emotion to make rational decisions with emotional regulation and improve decision making process by means of applyin...

    Vehicular platoon are a promising approach to new transportation systems, with innovative capabilities, such as vehicle sharing and adaptability to demand. This paper presents a multiagent solution to the platoon control problem with a linear configuration. In our case, a platoon is a vehicle train composed of a head vehicle and a variable number of followers. The head vehicle is human-driven or a... View full abstract»

    Human behavior representation in military simulations is not sufficiently realistic, specially the decision making by synthetic military commanders. In order to address some of these deficiencies, we have developed a computer implementation of Recognition Primed Decision Making (RPD) model using Soar cognitive architecture and it is referred to as RPD-Soar agent in this paper. The proposed impleme... View full abstract»

    Distributed constraint optimization is increasingly used for problem solving by multiple agents. However, there are situations where the system is made up of heterogeneous agents, for which the context, the structure, and the business rules define the interactions that are possible between them. As an example, supply chains are made up of interdependent business units having some form of customer-... View full abstract»

    Online buyer coalition formation problem is an application of e-commerce and distributed agent technology. Most existing works in this topic involve social utility based approaches that assume the agents' utilities to be transferable. However, we argue that there are situations where the transferable utility model is not well suited for the problem, and that coalition stability is a more important... View full abstract»

    Unlike mono-agent systems, multi-agent planing addresses the problem of resolving conflicts between individual and group interests. In this paper, we are using a Decentralized Vector Valued Markov Decision Process (2V-DEC-MDP) in order to solve this problem. It uses an utility function which is returning a vector representing both individual and group interest. The individual interest of an agent,... View full abstract»

    In science and engineering courses, students are often presented a situation for which they are asked to identify the relevant principles and to instantiate them as a set of equations. For an ITS to determine the correctness and relevance of the student's answer and generate effective feedback, it must map the student variables and equations onto the physical properties and concepts that are relev...
