End-users conduct various on-line activities. Quite often they re-visit websites and use services to perform repeated activities, such as on-line shopping. The end-users are required to enter the same information into various web services to accomplish such repeated tasks. Typing redundant information repetitively into such services negatively impacts the user experience. In this study, we propose...
We propose a statistical semantic analysis method for Chinese terms. We use words, part-of-speech (POS) tags, word distances, word contexts and the first sememe of a word in HowNet as features to train a Support Vector Machine (SVM) model for analyzing term semantics. The model is used to identify dependencies embedded inside a term. A Conditional Random Field (CRF) model is used afterwards to incorporate...
This paper examines the relationships between the many-valued logics G~ and G~n of Esteva, Godo, Hájek, and Navara, i.e., Gödel logic G enriched with Łukasiewicz negation, and neighbors of intuitionistic logic. The popular fragments of Rauszer's Heyting-Brouwer logic HB admit many-valued extensions similar to G which may likewise be enriched with Łukasiewicz negation,...
Main microblog research is focus on the structural analysis of social networks, rather than the text and topic analysis. Traditional topic detection methods could not be applied due to the microblog short text features and structural characteristics. We taken advantage of availability of latent dirichlet allocation (LDA) to expand the text feature space, and used frequency statistics for our topic...
This research proposes an expanded semantic graph definition that serves as a basis for an expanded semantic graph representation and graph matching approach. This representation separates the content and context and adds a number of semantic structures that encapsulate inferred information. The expanded semantic graph approach facilitates finding additional matches, identifying and eliminating poor...
Data availability in online social networks as well as the business world has lately not been an issue. Vast amounts of data are being generated by social networking users in the form of informal interactions. What has been an issue, is the transformation of data into useful information, that in time and with appropriate processing becomes knowledge. In this paper we examine knowledge generation under...
This paper defines and shows the merit of measures for quantifying the degree of relatedness of information of interest and the importance of new information found within a large number of free text documents. These measures are used for identifying and sorting free text documents that are found to contain related information of interest and, in some cases, new information of interest related to a...
Today, web services are widely used for data exchange. The format of individual messages exchanged among them is usually described with XML schemas in WSDL documents. It is a common practice that there is not only one but a whole family of formats each, for example, tailored for a specific consumer. In such environments, the design and maintenance of the web service interfaces and, in particular,...
In the context of asynchronously communicating services, responsiveness guarantees that a service and its environment have always the possibility to communicate. The responsiveness preorder describes when one service can be replaced by another such that responsiveness is preserved. We study responsiveness for possibly unbounded services with and without final states, and present for both preorder...
We challenge the validity of Dempster-Shafer Theory by using an emblematic example to show that DS rule produces counter-intuitive result. Further analysis reveals that the result comes from a understanding of evidence pooling which goes against the common expectation of this process. Although DS theory has attracted some interest of the scientific community working in information fusion and artificial...
This paper is about the 150 Digit project, a web 2.0 portal designed for the publicity and dissemination of the exhibitions set up for the celebration of the 150 years of Italian unity. Targeted at schools, 150 Digit encourages the active participation of the users to the classification (in terms of tagging) of the exhibition contents and to the creation of new contents. The social components of the...
Pervasive computing systems including smart phones, home computing systems, or intelligent home appliances collect and store more and more information about users. The amount of information that is constantly being accumulated for each user is enormous. Collected information comprises the user's digital data like messages, online social network connections, or tweets and the user's physical context...
In this paper we present the DLM 3.0 project's vision for e-mail communication in enterprise. The project promotes the use of semantic techniques, based on case studies and ergonomic analysis to improve current email tools, in an enterprise context. The project's realm is to create a corporate social network centered on email, with email being connected to the company tools, and automatically interacting...
Previously studied fuzzy bipolar conditions of type ”and if possible” are made of a mandatory condition c and an optional condition w. They allow expressing complex preferences of a conjunctive nature. We define in this paper, a new kind of fuzzy bipolar conditions of the form ”or else” which express complex preferences of a disjunctive nature. We show that the ”or else” form can be used as a negation...
Semantic information retrieval requires that we have a means of capturing the semantics of documents; and a potentially useful feature of the semantics of many documents is the temporal information they contain. In particular, the temporal expressions contained in documents provide important information about the time course of the events those documents describe. Unfortunately, temporal expressions...
Most research works related to FCA depend on the hypothesis of that the possession of an attribute by an object is crisp: either an object has an attribute, or not. When facing the complex real world, it is impractical to expect any individual has complete knowledge, so it makes more sense to admit uncertain formal concept analysis is a more powerful tool from a more realistic perspective. In this...
Many transformation systems for program optimization, program synthesis, and program specialization are based on fold/unfold transformations. In this paper, we investigate the semantic properties of a narrowing-based unfolding transformation that is useful to transform rewriting logic theories. We also present a transformation methodology that is able to determine whether an unfolding transformation...
Active sets are introduced in the context of providing a model to underpin mass assignment. It is argued that active sets provide an active definition of a fuzzy set where the agents providing the voting model are active and as such may modify their voting patterns depending on circumstances. We show that the model supports semantic unification and separation and therefore provides a fluid negotiating...
In this paper, we describe an approach to database preference queries based on the notion of fuzzy outranking, suited to the case where partial preferences are incommensurable. This model constitutes an alternative to the use of Pareto order. Even though outranking does not define an order in the strict sense of the term, we describe a technique which yields a complete pre-order, based on a global...
