As these tools become more ubiquitous with general population, different managment problems start to arise. As these members' interactions become large, it is impossible for manual handling of moderation tasks without automatic or semi-automatic techniques.Of course, web mining techniques are very useful for understanding text patterns or browsing patterns in Websites, opening an opportunity to develop new algorithms to discover community members' patterns which have to be moderated. There have been previous work done on text patterns discovery for moderation that have reduced the moderation task to finding spammers. However, the moderation problem is much more complex: it involves not only text but also behavior patterns from bulling of other members to fights between them. We present a dissimilarity measure which includes human interaction aspects combined with these interactions' contents semantics not just free words of text. We show how we successfully applied our method into a real Virtual Community of Practice to detect users that should be moderated.","PeriodicalId":263450,"journal":{"name":"Web Intell.

Such an exploration pattern is applicable to many systems, including shipment and travel planning. This paper formally introduces and analyzes a sequential variant of the general model. According to that variant, only a single agent engages in exploration at any given time, and when an agent initiates its exploration, it has complete information about the minimum value obtained by the other agents so far. We prove that the exploration strategy of each agent, according to the equilibrium of the resulting Stackelberg game, is reservation-value based, and show how the reservation values can be calculated. We also analyze the agents' expected-benefit maximizing exploration strategies when they are fully cooperative i.e., when they aim to maximize the expected joint benefit. The equilibrium strategies and the expected benefit of each agent are illustrated using a synthetic homogeneous environment, thereby demonstrating the properties of this new exploration scheme and the benefits of cooperation.","PeriodicalId":263450,"journal":{"name":"Web Intell.

Especially novice users need to acquire both knowledge about the underlying ontology structure and proficiency in formulating formal queries e.g. SPARQL queries to retrieve information from Linked Data sources. So as to simplify and automate the querying and retrieval of information from such sources, this paper presents an approach for constructing SPARQL queries based on user-supplied keywords. Our approach utilizes a set of predefined basic graph pattern templates for generating adequate interpretations of user queries. This is achieved by obtaining ranked lists of candidate resource identifiers for the supplied keywords and then injecting these identifiers into suitable positions in the graph pattern templates. The main advantages of our approach are that it is completely agnostic of the underlying knowledge base and ontology schema, that it scales to large knowledge bases and is simple to use. We evaluate all 17 possible valid graph pattern templates by measuring their precision and recall on 53 queries against DBpedia. Our results show that 8 of these basic graph pattern templates return results with a precision above 70%. Our approach is implemented as a Web search interface and performs sufficiently fast to provide answers within an acceptable time frame even when used on large knowledge bases.","PeriodicalId":263450,"journal":{"name":"Web Intell.

A qualitative way is desirable for service selection according to agents' preferences on non-functional Quality of Service QoS attributes of services. However, it is challenging when the decision has to be made for multiple agents with preferences on attributes that may be incomplete. In this paper, first use a qualitative graphical representation tool called CP-nets to describe preference relations in a relatively compact, intuitive and structured manner. We then propose a preference reasoning algorithm to construct a derivation tree from a CP-net for each agent and then generate all service patterns for this agent. The Rank semantic is used together with the Lex semantic to provide the ordering of different service patterns. After that, we merge ranked service patterns for all agents and select a set of services that satisfy these agents the most. Finally, we also propose a semantic validation algorithm to show the satisfactory degree of the best service patterns according to other voting semantics. Experimental results indicate that this method can always obtain optimal outcomes which closely satisfy all agents, within acceptable execution time.","PeriodicalId":263450,"journal":{"name":"Web Intell.

Ras","doi":"10.3233/WIA-130268","DOIUrl":"https://doi.org/10.3233/WIA-130268","url":null,"abstract":"Recently, numerous successful approaches have been developed for instrument recognition in monophonic sounds. Unfortunately, none of them can be successfully applied to polyphonic sounds. Identification of music instruments in polyphonic sounds is still difficult and challenging. This has stimulated a number of research projects on music sound separation, new features development, and more recently on hierarchically structured classifiers used in content-based music recommender systems. This paper introduces a hierarchically structured cascade classification system to estimate multiple timbre information from the polyphonic sound by classification which is based on acoustic features and short-term power spectrum matching. This cascade system makes a first estimate on the higher level decision attribute which stands for the musical instrument family. Then, the further estimation is done within that specific family range. Experiments showed better performance of a hierarchical system than the traditional flat classification method which directly estimates the instrument without higher level of family information analysis. Traditional hierarchical structures were constructed in human semantics, which are meaningful from human perspective but not appropriate for a cascade system. We introduce a new hierarchical instrument schema according to the clustering results of the acoustic features. This new schema better describes the similarity among different instruments or among different playing techniques of the same instrument. The classification results show the higher accuracy of cascade system with the new schema compared to the traditional schemas.","PeriodicalId":263450,"journal":{"name":"Web Intell.
