A parameterized algebra for event notification services
- Trang 61-63
Event notification services are used in various applications such as digital libraries, stock tickers, traffic control, or facility management. However to our knowledge, a common semantics of events in event notification services has not been defined so far. We propose a parameterized event algebra which describes the semantics of composite events for event notification systems. The parameters ser......

Logic Trạng thái Phân tán Dịch bởi AI
- Trang 55-57
Chúng tôi giới thiệu một logic thời gian để lý luận về các ứng dụng toàn cầu. Trước tiên, chúng tôi định nghĩa một logic mô-đun cho địa phương tính, nhúng các lý thuyết địa phương của mỗi thành phần vào một lý thuyết về các trạng thái phân tán của hệ thống. Chúng tôi cung cấp cho logic một hệ thống tiên đề đầy đủ và chuyên sâu. Sau đó, chúng tôi mở rộng logic với một toán tử thời gian. Đóng góp củ......

Evolution specification of multigranular temporal objects
- Trang 78-85
The main key feature of temporal databases is to maintain all values taken by object attributes over time. Since historical information may be needed at different levels of detail, multigranular temporal databases have been introduced, in which different attributes can be stored at different temporal granularities. An important issue that has not been addressed, however is that the required level ......

On non-local propositional and local one-variable quantified CTL*
- Trang 2-9
We prove decidability of 'non local' propositional CTL*, where truth values of atoms may depend on the branch of evaluation. This result is then used to show decidability of the 'weak' one-variable fragment of first-order (local) CTL*, in which all temporal operators and path quantifiers except 'tomorrow' are applicable only to sentences. Various spatio-temporal logics based on combinations of CTL......

Temporal views as abstract relations
- Trang 116-123
Many natural languages use prepositions to mark relations between entities of various kinds-between physical entities and their spatial locations, between temporal entities and their temporal locations, between abstract entities of various kinds (e.g. between ideas and their 'mental locations'). I show that the consequences of using prepositions to relate temporal entities emerge naturally from th......

A continuous planning framework with durative actions
- Trang 108-114
This paper describes a continuous planning framework to be used by a planning agent situated within an environment, which reasons about goals with priorities and deadlines, and actions with duration. The framework assumes that goals may be generated continuously, which requires the interleaving of planning and execution. Constraints upon time may mean it is not possible for all goals to be achieve......

A finite-state approach to event semantics
- Trang 124-131
Events employed in natural language semantics are characterized in terms of regular languages, each string in which can be regarded as a motion picture. The relevant finite automata then amount to movie cameras/projectors, or more formally, to finite Kripke structures with partial valuations. The usual regular constructs (concatenation, choice, etc) are supplemented with superposition of strings/a......

Reasoning with disjunctive fuzzy temporal constraint networks
- Trang 36-43
The disjunctive fuzzy temporal constraint network (DFTCN) model is a framework that allows reasoning with fuzzy qualitative and quantitative complex temporal constraints. However, its general complexity is exponential. In this work, we review methods that can reduce this complexity, based on graph topology and preprocessing. The final goal is to integrate all these methods into a general tool for ......

Indexed flows in temporal /spl times/ modal logic with functional semantics
- Trang 146-153
Two classical semantical approaches to studying logics which combine time and modality are the T /spl times/ W-frames and Kamp-frames (Thomason (1984)). In this paper we study a new kind of frame that extends the one introduced in Burrieza et al. (2002). The motivation is twofold: theoretical, i.e., representing properties of the basic theory of functions (definability); and practical, their use i......

A similarity search method of time series data with combination of Fourier and wavelet transforms
- Trang 86-92
Time-series data, such as stock exchange rates and weather data, has widely been used in many fields. Similarity search of time-series data is important because it is useful for predicting data changes and searching for common sources. In this paper, we propose a new similarity search method of time-series data using both a discrete Fourier transform (DFT) and wavelet transform (WT). A method of r......
